Certificate type
A lightweight, breathable, insulated traditional lime plaster mix for internal or external use.
Application
Pour no more than 15 litres of clean water into a mixing tub.
Gently add Warmcote, mixing with a plasterer’s paddle, don not add all of the dry plaster at once, bring gradually 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 Warmcote is uniformly mixed, gently add all the fibres from the small bag and mix thoroughly, it does not need to stand, it can be used straight away.
DIRECTIONS FOR USE
Ensure that the background is clean and free from loose friable or dusty material.
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 however recommend its use as a finish on timber frames or backgrounds where background movement is a factor, a finish coat of Limecote would however be perfect.
Description
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.
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.
Features and benefits:
- Breathable, flexible, very lightweight and can be applied at practically any thickness.
- Useful for making good damaged clay lump, cob, masonry or daub.
- Made with lightweight minerals as the aggregate in place of sand.
- The lambda value of Warmcote is approximately 0.140 W/mK; about five times more thermally efficient than a standard lime plaster and eight times better than sand and cement.
