Breathable | Lightweight | Flexible | Sustainable
Warmcote™ has been developed to offer insulation for traditional, historic buildings where the use of modern systems would be inappropriate and potentially damaging.
Used in conjunction with sustainable, breathable boards such as cork, wood fibre or sprayed hemp, Warmcote's traditional lime plaster mix can make a significant improvement to the living environment of a home, as well as reducing the energy bill and the carbon footprint. The original drive behind its development was to offer some thermal benefit to traditional 'hard to insulate' buildings, particularly timber framed buildings where it may be aesthetically undesirable to apply boards to the exterior. It is breathable, flexible, very lightweight and can be applied at practically any thickness. The best achieved so far is 8" in two passes. Warmcote is incredibly useful if you are making good damaged clay lump, cob, masonry or daub.
Warmcote is made with lightweight minerals as the aggregate in place of sand. The results of testing so far put the Lambda value of Warmcote at around 0.125 W/mK. That is about five times more thermally efficient than a standard lime plaster, and eight times better than sand and cement.

Warmcote is a dry ready mixed feebly hydraulic lime plaster for internal or external use. It is packaged in 25kg recyclable LDPE bags.
MIXING: Pour no more than 7 litres of clean water into a mixing tub. Gently add Warmcote, mixing with a plasterer's paddle. Do not add all of the dry plaster at once, bring gradually up to the required consistency.
If necessary, add more water. There is no 'right or wrong' amount of water to add, it can be used at whatever consistency best suits the job, be it thinned down for spraying, or thick enough to hand trowel. Once the Warmcote is uniformly mixed, gently add all the fibres from the small bag and mix thoroughly. Ensure that the background is clean and free from loose and friable material. Lightly damp down, avoiding a film of water on the surface. Warmcote can be used for the full thickness of plaster from dubbing out to a polished finish in one, two or multiple coats on most backgrounds. It also works very well as a scratch coat beneath a Limecote finish. We would not recommend its use as a finish on timber frames or backgrounds where background movement is a factor.
Caution: Calcium Hydroxide is an IRRITANT.
We have no minimum order quantity: you can order as many or few bags as you like. We can deliver to the whole of the UK. For a smaller quantity (1-3 bags), we would normally despatch these in boxes via Parcelforce/DHL. The cost is generally governed by the number of packages. Anything more than 1-3 bags would go onto a pallet, up to a maximum of 40 bags per pallet (1 tonne). This will be a tail lift delivery, effectively dropped at the kerb/lorry side where safe. Please advise us of any special delivery instructions, as we will not be held responsible for any issues arising at the delivery point. The drivers will work with you to get your pallet delivered safely and effectively. Pallet delivery costs are priced per pallet and are postcode driven, and we can offer additional services such as AM delivery and timed delivery. All are chargeable extras. This is a service that we pass on the cost that we pay - we do not make any money out of this service and we do not charge for the pallets. The other option is collection from us in Haverhill: again, this needs to be booked in. Because of lead times and safety concerns, we cannot currently accept walk-ins due to the current situation.
"Limecote and Warmcote are ideal products for use on timber framed buildings and low strength substrates with their excellent flexibility, bond, and light weight compared to sanded plasters. Being dry bagged makes it easy to transport and store, with the added advantage of being able to adjust the mix to suit thin or very thick coats without compromising the product, or the quality of the finished work."
"Best Lime plaster system on the market!! I found this accidentally due to the coronavirus pandemic as stocks of everything ran out, and it's changed the way all of the plasterers in our area are now plastering conservation listed buildings as well as new builds... due to its unique formula and characteristics of extremely quick application, drying, workability and breathability. It's rare to find such a great product and more importantly a great level of customer service in the build industry."
"As self-builders of a very large community project, Limecote has been an outstanding product, making all the difference to our progress. It keeps well in sealed bags even outside; it mixes easily and safely; being half the weight of sand-based products, it is easy to carry and apply to the walls; excellent adhesion mean that less is dropped and wasted... and not having to constantly limewash going forward make it a no-brainer."
