External Decorative Lime Plaster, Exeter

Exeter townhouse external repairs and redecoration

We were tasked by our client to restore their lovely townhouse, including the external decorative lime plaster. The house has not had a huge amount of work done to it for quite some time and when we hacked off the existing render, we discovered a multitude of repairs to be made before we could consider re-plastering. The client is based abroad and we were liaising via email mainly. It can be difficult when you don’t meet a client face to face; we were relying on photographs to show the client the extent of underlying damage to their property.

Initial works

Before Earthouse could get on site, we arranged the scaffolding via Shane Hardy Scaffolding Ltd. Scaffolders at this time of year are incredibly busy and we had a tight schedule to work to. The property has an old glass conservatory at the front and we needed to remove the glass panels so the scaffolding could be erected close to the house. We used locally based Cullompton Glass & Glazing to do this. The glass panels are now being carefully stored by them, ready to be replaced once we have finished the rendering work.

Removing existing render

The render on the building was cement based and incredibly thick as you can see on the photograph below; getting it off the building was hard work, especially during this summer’s heatwave! Our team worked tirelessly for a week hacking the render off so we could get started on the restoration work. The problem with cement based render is that if any defect in the building or roof allows water ingress, the water is unable to escape through the cement render. This causes a build up of water within the structure of a building and during excessive cold or hot periods, it can do a lot of damage to your walls. The frost and thaw process means that water turned to ice expands and cracks the substrate. In this case, the substrate was stone and you can see on the photograph below that the water had cracked the majority of stone in this top elevation of the house, leaving it very unstable.

Stone & brick repairs

In order to ensure that the damaged stone in the photo above was stabilised, we raked out all the loose pieces and packed the area with lime prior to rendering.

On other areas of the house, there were a number of repairs to contend with. In the phot below you can see how we have used stainless steel helipads and resin to repair and stabilise the stone and brick work on top of the stone plinth.

Lime rendering

Lime is the correct material to use on this type of building. It allows moisture to dissipate in a way that sand and cement based renders do not. For the exterior walls we have used … in a three coat build up. We always find it quite amazing to look underneath the render of a house and discover that it is not as you might expect. You may imagine that houses are built solely of brick or of stone, and perhaps they were initially. However, their history may have seen repairs and additions and you may find that a house is constructed of various types of stone from different localities and various different bricks. The worst cases we have seen are where rubble has literally been stuffed haphazardly into gaps! The photo below shows just a few different building materials on this house.

External decorative lime plaster

Prior to us commencing the removal of the existing render, we took profiles of all the areas of decorative plasterwork. We did this so that we could replicate the existing decorative lime plaster exactly. Once the profiles were taken we were able to create templates from wooden blocks and stainless steel, which we could then use to shape the lime plaster as per before. In order to be able to do this, we used a particularly thick mix of lime plaster so it would hold the shape. We shaped the plaster when wet and then allowed to dry slowly. It is imperative in this extremely hot weather that lime plaster does not dry out too quickly as it will crack. In order to slow the drying process we mist the walls with a fine water spray and we also use wet hessian ‘curtains’ on the scaffolding. When the breeze passes through the wet hessian it cools the walls.

To see how we formed the intricate decorations on the lime plaster, have a look at our video.

In order to retain the character of the building we have reinstated the lines that would have originally appeared in the plasterwork.

After we had created the tools above, we used these to recreate the original Georgian decorative plasterwork. This was mainly around the top of the house, although there was some work to be done around the windows.

Painting Lime Plaster

Lime plaster is a breathable surface material. In order to preserve this breathable quality, lime plaster should be painted using a breathable coating. This could be a lime wash or a silica paint. On this occasion we recommended using silica paint from Farrow & Ball. After taking advice from the local Planning Office, our customer also spoke to their neighbours; in a row of houses it is also a good idea to find out if anyone else is planning a near future repaint and if so, to see if an element of colour matching could be incorporated. Depending on where you live there may be different restrictions in place as to what colour you can use on your property; this is particularly important to take into account when painting a listed building. However, on this occasion there were no restrictions in place. So that the house remains sympathetic to its surroundings, a near match to the existing white colour is being used. Our customer also opted for marginally darker grey to pick out the detailing on the decorative plasterwork.

Building Restoration Chepstow, Monmouthshire

Building restoration project

We were contacted just after Christmas to undertake works on a building restoration project in Chepstow. In close connection with Parker SW Ltd, we have done remedial stone work to the cottage walls. This included patching a number of small holes. There was not a huge amount of remedial work required, so we were quickly onto lime rendering the internal walls.

The first photograph shows the cottage wall with the flattening coat.

The second photograph shows the window surround covered with flattening coat. The customer wanted to preserve the fireplace detail, which you can see in later photographs.

We re-rendered using a three coat build up of lime mortar, which allows the building to breathe. The photograph below shows the scratch coat of lime render on the internal walls of the sitting room. The stone lintel has been cleaned up and remains uncovered. The drying process will take about 8 weeks in total, these walls are nearly ready for the final coat.

Earthouse were also asked by the customer to install an oak timber floor. Once the floorboards were laid, the oak was treated with lime, which gives it a weathered look. The oak is then polished to finish it and protect the wood.

We visited the property on a number of occasions to build up the layers of lime render. Our most recent visit was to finish up and complete any snagging. This includes filling any small cracks which naturally appear as part of the drying process, as shown in the photo below.

Installing windows and oak trusses

The customer chose to replace the old windows and chose a wooden frame in keeping with the building. The trusses were also replaced using oak.

Church Restoration, Devon

Our church restoration and conservation projects

Earthouse Building Conservation have been very fortunate to have been involved in a number of church restoration and conservation projects over the years. There are a wide variety of churches in Devon, built at various stages throughout recent history. You can read more about the history of Devon’s churches on the Britain Express website.

The very first church we worked on was Westwood Chapel around 10 years ago. This was an internal job, re-rendering the walls and around the door and a window. You can read more about this job in our blog post Earthouse Projects.

Colebrook Church Restoration

We have recently completed work on the Church of St Andrew in Colebrook, near Crediton in association with Skinner Construction.

The church tower

The church is a Grade I listed building, with the original structure thought to have been built in the late 13th and early 14th centuries. It is mainly built in volcanic stone and read sandstone. The church has undergone a number of restorations; British Listed Buildings gives a thorough history in their entry on the Church of St Andrew. Earthouse was contracted to do a number of structural repairs and to re-point using lime on the south elevation and east gable.

Restoration work commences at the Church of St Andrew, Colebrook

The scaffold in place ready for work to commence

We were working from a specification provided by Russ Palmer – Historic Building and Church Architect. Russ came on site to agree the colour of the lime pointing mix.

Our sample panels were comprised of three different lime and sand mixes as shown in the photo below:

1. seashell sand from Padstow Sea Sand Ltd

2. local red 50/50 sand from an Uffculme quarry

3. yellow 50/50 Chardstock sand

Sample panels - church restoration and conservation - re-pointing

Sample panel showing 3 mortar mixes using different sand

Russ decided that mix no 1 was the most in keeping with the church and the rest of the existing mortar.

The first few days were spent hacking out the existing mortar. It became apparent that there were a few large repairs that needed to be done prior to us re-pointing. We hadn’t been able to see this on our previous visits as there was no access to the higher areas until the scaffold was in place. We used stainless steel helical ties and resin to repair large cracks within the stone work. This strengthens and stabilises the building. The repairs took around 2 days. The lime re-pointing then took a further 13 days.

The photos below are the final finished re-pointing.

Building with Mass Cob

Building cob walls

If you are considering building or re-building using cob, you have two options. You can either use cob blocks or mass cob.

We have previously discussed the benefits of using cob as a sustainable and ecological option for new builds and if you have an existing cob building this should always be repaired using cob. This is not only to maintain the integrity of the structure and its history, but also to keep your local Conservation Officer happy!

Mass cob wall construction

Cob blocks

Cob blocks are crafted from pre-mixed mass cob, formed into manageable sized building blocks, which are left to dry naturally until they are a strong, solid building material. Cob blocks can be purchased from specialist suppliers, such as J&J Sharpe in Devon, usually by the pallet.

The quality of cob blocks can vary depending on the subsoil used and the craftsmanship of the producer. On occasion it can be difficult to get hold of cob blocks, due to the limited seasonal drying times in the UK and increases in demand.

Generally, we would use cob blocks to repair existing cob walls. Defective cob can be cut out and removed in order to easily insert cob blocks. They would then be fixed into place using an earth mortar. Of course it is possible to build new walls using cob blocks, and this is certainly something we have done in the past. You will need to weigh up the availability of cob blocks and a mass cob source, as well as considering price and weather conditions when making your decision as to whether to use cob blocks or mass cob for your project.

Cob bricks

You may also see cob bricks being mentioned in your quest for more information on this topic. Cob bricks are smaller versions of cob blocks and may be used for smaller repairs.

Mass cob

Using mass cob is cob building in its most basic and original form. Mass cob is produced in a cob pit and uses the following materials:

  • Subsoil (the clay/silt/aggregate that lays beneath the surface i.e. under the topsoil)
  • Wheat or barley straw – fibrous straw strengthens the mass cob, binding it together
  • Water
  • Coarse sand – only if necessary, depending on the composition of the subsoil

Mass cob can be dug out and mixed ‘by hand’ or with the use of a digger. The topsoil is dug out and removed. A pit is then dug to the required depth and the subsoil is set aside for mixing. Once the pit has been dug out, some of the subsoil is added back in and mixed with good quality wheat or barley straw and clean water. The materials are then thoroughly mixed together until they are fully integrated and consistent throughout. This process is continued until you have enough supply of mass cob and may be ongoing throughout a project.

I prefer a dryer mix, although others may find a wetter mix preferable. Some people choose to combine the cob mix using their feet to tread in, but you can’t do this on a large scale and a digger can be used instead. Additional pits can be dug on site to supply your cob mixing pit.

Coarse sand may be added to the mixture to give the mass cob more body and to help with drying if you have a mainly silt and clay subsoil. If your subsoil already contains a high proportion of aggregate, this may not be necessary.

Cob pit

A cob pit can be located on site, which has advantages when it comes to cost and availability. We have recently been working on a site with a cob pit in Mid Devon – see the video below showing how the cob is mixed.

COB PIT!!Cob has got to be the most eco friendly building material on the planet. The earth is plentiful and the carbon footprint can be measured in metres rather than miles! We are mixing by digger, but you can do this manually. This pit is on our site, straw is being added to strengthen the mix.#masscob #devoncob #ecobuilder

Building with mass cob vs building with cob blocks

There are advantages to building with both cob blocks and mass cob. See the table below for more information.

Mass CobCob blocks
Available on site, dependent on siteBought from a supplier, not always readily available
Is made with the local subsoil, so true to the integrity of the buildingReady to use immediately
Anyone can mix mass cobCan be used all year round
Labour intensive Remain the same size
Limited by supply on siteShorter drying times (already dry when bought)
Can be used all year round, but would need full scaffold coverEasy to use for repairs to existing cob
Shrinkage when drying must be taken into account
Longer drying times
Creates a mono structure – very strong

Mass cob mono-structures

A cob block wall is without doubt a strong structure, however, due to the nature of the blocks and the use of mortar joints, it is not as strong as a wall built from mass cob. Mass cob walls and buildings are known as mono-structures; there are no joins, which gives the building enormous strength and when maintained properly these structures have been recorded as lasting hundreds and thousands of years.

Exterior mass cob walls tend to be built 600mm – 1000mm thick. It is not necessary to build the internal walls this thick, but they would still need to be larger than a regular brick wall.

Mass cob can be transported from the cob pit, to the site of the building using trucks and trailers or if close by, wheelbarrows and by hand. The video below shows work taking place at one of our sites. Mass cob is being added layer by layer in ‘lifts’ of 600-900mm. You can see the stone plinth below which provides a stable base for the cob wall, but more importantly it limits water getting into the cob later on, which can cause damage and even collapse.

Cellar restoration project, Devon

Cellar restoration project

Prior to us becoming Earthouse Building Conservation Ltd, we were just plain old Earthouse. One of the first projects we undertook as Earthouse in 2002 was this fantastic cellar restoration. The customer rang us the other day to discuss another project at her property and when I went to visit I couldn’t resist asking for another look at the cellar! Unfortunately in 2002, I don’t think I had a phone that could take photos and I wasn’t keen on lugging a camera around building sites, so I don’t have any before photos to show you, but this is what the cellar looks like now.

Cellar restoration using lime render, Devon

The cellar restoration was part of a larger project at the house. Myself and the owners were unsure of the history of the house and the reason for the niches in the cellar – was it used to store food? Wine? Someone even suggested it looked like a morgue for infants. I am not sure about this theory! As you can see the owners now use it to store wine, a great use for a unique space. For more information about cellar restoration, there is an article in the Building Conservation Directory.

Lime plasterwork

The niches in the cellar have been carved out of an extinct riverbed, we could see the layers of silt when we started restoring the cellar. There were a number of structural repairs we had to carry out prior to the rendering, which we did using cob blocks, lime mortar and then coated with lime render. This was then lime washed. Limewash is a great product but it does need redoing relatively regularly to keep it looking fresh and to maintain its’ protective qualities. The cellar has not been lime washed since we did the original work, hence why it is looking a little tired. We will post an update once we have carried out the new lime washing.

If you have a project you would like to discuss further, please Contact Us.

Cob cottage restoration and external lime rendering, Mid Devon

Cob repair to external walls

As with many beautiful cottages we come across in Devon, this one had been coated in a sand and cement render and painted with a non-breathable plastic based paint. As we know very well by now, plastic paints are not good for the environment…well, they certainly aren’t that great for your house either! This cottage is located on a busy road so had a few challenges in that respect. We carefully risk assess all our jobs prior to commencement and ensure that we take appropriate safety measures.

We began by removing the cementitious render, uncovering a few damaged patches of cob in the process. The owner had contacted us because they had signs of damp and were well aware that they needed to remove the existing render in order to stop the problem getting any worse. Once the cob was patched using cob blocks supplied by Scott Parr, we prepared the substrate for external lime rendering.

External lime rendering

For this job we used a three coat build up of lime render. External lime rendering should only be undertaken at certain times of year; lime render that is caught out by frost before it is fully dried out or ‘cured’ can be problematic later down the line. Be aware of this if any builder suggests they can lime render the exterior of your house in the UK during the winter months! This work was undertaken last summer.

The photograph above shows the first flattening coat of lime render before if has fully dried out. There are gaps around the windows as the customer was having them replaced, but we were able to work around this. We ‘made good’ around the windows once they were installed. The stone buttress is a great feature of the house and was left revealed; in later photographs you can see this has been cleaned and re-pointed.

Silica paint decoration

The customer chose to paint their newly lime rendered cottage using a silica paint system produced by Sto Ltd.

The photograph above shows the road facing side of the cottage. The customer chose a vibrant shade of silica paint, produced by Sto Ltd. Paint colour is a very personal choice and whilst some customers prefer to independently make their decision, Earthouse can help advise on shades and colours in order to make the very best of a building. On this occasion and on our advice, the customer has changed their mind and decided to repaint at a later date in a more subtle colour. The photographs below show the completed lime rendering and silica paint decoration on the cottage.

The stone buttress has been re-pointed with a lime mortar, with a locally sourced red sand from a quarry just three miles away in Uffculme. The pointing will aid in preserving the stone work. This lime mortar is an NHL 2 hydraulic lime mortar, which is suitable for the soft Heavitree stone of which the buttress is constructed.Lime render on thatch cottage with silica paint decoration, Mid Devon

External lime rendering, Devon

Lime rendering, Devon

Our customer asked us to undertake the external lime rendering on the rear of her cob and brick cottage in East Budleigh, Devon. At Earthouse Building Conservation we work on both large and small building restoration and conservation projects. We were pleased to accept this job as we had previously done the front exterior lime rendering and some internal works inside the cottage.

Preparation of substrate for lime render

The substrate on the cottage is a mixture of old cob and newer red brickwork. We removed the sand and cement render; fortunately the cob below was in a good condition so we did not need to do any repairs on this occasion. The timber lintel above the downstairs window was rotten and full of woodworm, which meant that the wood was flaky and crumbling. We replaced the rotten wood with a new oak lintel.

 

 

The photo’s below show the flattening coat of lime render and the final application. The window frames will be cleaned to finish the job. The render used was a hydraulic NHL 2 mix, which takes approximately 2 weeks to dry out and it will then be decorated with a silica paint system.

A guide to Cob and Lime Maintenance

Cob and Lime Maintenance

We talk a lot about restoring cob and lime buildings on this site – probably because by the time Earthouse has received a phone call, there is already a problem! In this blog we are going to talk about maintaining your building so that you do not get to this point.

Unfortunately, if you can see the problem, it generally means there is something underlying. In the worst cases we have seen, this has been severe damage due to complete deterioration of the cob structure. The most common reason customers contact us is to say that there is a crack in their plaster, or a damp patch has appeared. When we hear this, we know that the issue will be that a cob or stone wall has been rendered using modern cementitious render. Modern cementitious renders have their place; on modern buildings with a damp course and effective air circulation systems. They were never meant to be used on cob or stone walls and consequently cause problems.

Water damage to decorative plaster

Water damage to decorative plaster

The damage is almost always caused by water ingress. Modern cementitious renders are waterproof; this means that if water somehow gets in it cannot escape, so it remains within the structure and moisture builds up over time. The frost and thaw process aggravates this deterioration, resulting in the cob degrading into a topsoil-like substance.

However, cob buildings if treated correctly can last for hundreds or even thousands of years; as long as you are prepared to spend money putting right what previous generations have got wrong, there is no reason your building cannot last for a similar timespan. In addition to this, conservation officers will no longer allow you to render cob in sand and cement, as this does not conserve the integrity of the building.

Cob and Lime Specialists

As a cob and lime specialist, if we can see cracking or damp on your walls, we will assume that there could be issues with the underlying cob. They may also say that they cannot diagnose the extent of any damage without being able to see beneath the plaster. As a guide, if you have excessive or large visible cracks to the render, you should expect a number of cob repairs.

Whilst it is straightforward to give a cost for lime rendering per square metre, it can be difficult to provide a quotation for remedial cob work. Generally Earthouse advises customers to allow a 15-20% contingency for cob repairs, although this may differ depending on the situation. There is no steadfast way to deduce the state of the cob without taking the render off; we have worked on properties where the render looks fine, but the cob is really badly affected underneath. Conversely we have taken off badly damaged render expecting the worst, only to find that minimal cob repairs were required.

This shows an extreme example where the cob structure had been undermined at the base of the wall and was subsequently repaired by Earthouse

How to avoid cob deterioration

If you have a cob property there are things that you can do to maintain the integrity of your building.

Cob cottage with cementitious render removed

  • Prior to buying a cob property, you might consider asking a cob and lime specialist to accompany you on a site visit. If the property has been rendered in anything other than lime it may be that you can negotiate on the price, as ideally you would re-render the house.
  • If you suspect a cob property has been plastered in cementitious materials, ask the surveyor to confirm the render material and the paint used.
  • If your house is cob, always consult a builder that has specialist knowledge of cob and lime render.
  • Remove aggressive creeping plants at the earliest opportunity as they can damage structures. Be aware that any plant or tree that touches the building can affect the render negatively, particularly if it is windy.
  • Damaged or blocked guttering is probably the most common cause of water ingress; check your gutters and ensure they are cleared regularly.
  • Thatched houses tend not to have guttering; ensure there is an alternative way to drain excess water away from the house, for example via a French drain soakaway.
  • If you have anything other than lime render on your walls we would suggest that you remove this internally and externally. If you have a cob property, this will then need to be re-rendered in lime based products. Stone or brick properties without a damp course will need to be treated with lime based mortars throughout.
  • If removing the render internally and externally throughout the house is not an affordable option, it may be that there are key areas that you could restore to prevent further damage.
  • Use the correct decoration on walls that have already been lime rendered. We recommend lime wash or you could choose one of the excellent silica based paints internally. Externally you also have the option of using a casein distemper or a clay based paint. Please see our blog Lime Wash vs Silica Paint for more detail.
  • If you decide to use lime wash, bear in mind that you will need to re-decorate within 3-5 years to maintain your aesthetics.

Finally if you are concerned about your property, please contact us. We are able to provide free advice about the best way to approach any remedial or preventative work.

Tadelakt Bathrooms

Tadelakt Bathrooms and Wet-rooms

Earthouse recently worked on a new Tadelakt bathroom in association with Parker SW Ltd. Although it is an ancient plastering material, Tadelakt can create a contemporary look. When applied correctly, Tadelakt creates a waterproof surface meaning it is ideal for bathrooms and wet-rooms, reducing the requirement for tiles and unsightly grouting. It is also superior to regular plaster in bathrooms, which simply soaks up water, causing potential damp issues and mould.

View of the Tadelakt bathroom wall.

View of the Tadelakt bathroom wall.Traditional bathroom tiling has not been used here because it is simply not required. Showers and sinks can be fitted straight onto the Tadelakt walls. 

Polishing the Tadelakt

Tadelakt can be mixed in a range of colours and shades. On this occasion, a light grey was chosen. This is the largest area we have plastered in Tadelakt and required a lot of polishing. Tadelakt is hand polished with a polishing stone, we use porcelain polishing stones which can be purchased from Mike Wye Associates.

Once the Tadelakt has been polished it needs to be sealed. This is a three stage process; initially olive oil soap is used, followed by punic wax and finally carnauba wax.

Tadelakt is low maintenance once is has been sealed; it will require re-sealing periodically, but this can be done by the customer as required. It is best to avoid using harsh chemicals on the plaster; soap and water will clean it effectively.

Bespoke Tadelakt

Earthouse can create bespoke bathrooms, wetrooms and feature walls. Due to it’s versatility we can create unique baths, seats and beautiful storage features. Tadelakt is not limited to bathroom usage; it can be used throughout a house, injecting colour and an interesting fresh style. It can also be used externally.

For more information, please see our previous post about Tadelakt plastering.
