Ty-Mawr Limewash - With Casein

Availability: In stock

Limewash is the traditional paint used to finish lime work both internally and externally. Ty-Mawr's high-quality limewash is the ideal paint to use on lime plaster/render or masonry/brick pointed with lime mortar as it is the most vapour permeable paint.


 It is possible to add other ingredients to limewash, some of the most popular are; casein, to help it adhere to the background. Only add 500g casein powder (mixed into a paste), to a 20-litre bucket of limewash. We would recommend that this is used internally where a limewash aesthetic is required but where e.g. residues on the wall mean that a pure limewash will struggle to adhere. 


It should be noted, that additives can compromise the vapour permeability of the wall and so should be used with caution. Many limewash ‘paints’ on the market may have acrylics or other additives that may not be desirable technically for the building or environmentally - always

Details

Limewash is the traditional paint used to finish lime work both internally and externally. Ty-Mawr's high-quality limewash is the ideal paint to use on lime plaster/render or masonry/brick pointed with lime mortar as it is the most vapour permeable paint.

This is an extremely cost-effective paint and has good coverage - 20 litres will cover 60-80sqm per coat. It is now available in a beautiful range of tints and full colours to suit all tastes and budgets.

It has a matt finish and a 'depth' which most modern paints lack. It reflects light and appears to 'glow' in sunlight. The Ty-Mawr Limewash is a creamy off-white to which pigments can be added or premixed colours are available.

External Limewash 
Other additions to limewash
As well as adding fine aggregate to make a shelter coat or pigments to produce a colour, it is possible to add other ingredients to limewash, some of the most popular
are:
• casein, to help it adhere to the background. Only add 500g casein powder (mixed into a paste), to a 20-litre bucket of limewash. We would recommend that this is used internally where a limewash aesthetic is required but where e.g. residues on the wall mean that a pure limewash will struggle to adhere.
• raw linseed oil can also be used, usually externally at a ratio of a 100ml per 20-litre bucket.
• tallow - again this helps the limewash to bind and weather, as it is a ‘fat’, it is best added when the quicklime is ‘slaked’ (so that it dissolves when the limewash is ‘hot’), it is possible to buy pre-made ‘tallowed limewash’ which avoids having to deal with quicklime yourself.

It should be noted, that additives can compromise the vapour permeability of the wall and so should be used with caution. Many limewash ‘paints’ on the market may have acrylics or other additives that may not be desirable technically for the building or environmentally.

Benefits
  • Has been used as a decorative and protective finish for 1000s of years
  • Is extremely "breathable" (water vapour permeable) enabling any moisture that has entered the building to evaporate which results in healthier, drier buildings.
  • Contains no VOC's, this makes it safe for you and your familiy to live with (N.B. it is caustic, so skin and eyes should be protected during application but it does not off-gas or pollute the room in anyway).
  • Is mildly antiseptic so is still used in agricultural buildings prior to e.g. lambing, to help 'cleanse' the internal environment 
  • Gives a beautiful matt aesthetic which no modern paint can match and is just perfect for old buildings 
  • Tther components can be added to help it adhere to more backgrounds and to improve it's weatherability, please see The Lime Handbook or contact us for advice - tymawr@lime.org.uk 
  • Powder pigments can be added to create a limitless range of beautiful colours!
FAQs

How much limewash do I need? 

The number of coats vary but usually at least three coats are required. 

We work on 3-4 square metres per 1 litre per coat. 

How do I apply limewash? 

Please refer to our technical sheet in documentation for full details on the application of limewash. It can not be applied in the same way as an 'ordinary' paint! It is important to follow the manufacturer's instructions to avoid excessive dusting and failure.

How do I prepare the surface? 

The surface must be clean and free of lichen, old paint etc. It may be necessary to apply a 'shelter coat' which will give the limewash a perfect 'key' and helps the longevity of the limewash. 

Isn't limewash dangerous? 

Limewash, like all lime products is caustic, but as long as you wear goggles and protect your skin, there is no problem with using it. 

Do I need to limewash every year? 

No, a well prepared and well applied limewash to an appropriate background will last many years (usually 5-7 years), however, we still have many customers that limewash agricultural buildings internally every year as it is mildly antiseptic. 

Can I use limewash on wood? 

It can be used on wood - indeed the 'look' on limewashed wood has been quite fashionable in recent years, it does however degrade more quickly than on walls (although this is gradual and we think gives a pleasing aesthetic!) 

Can I use limewash over modern paint or plasterboard? 

These are not ideal backgrounds for limewash although it is possible to add other ingredients such as casein or linseed oil to help it to adhere if you are keen to have the 'feel' of limewash and have a background that is going to be problematic - call/email us for advice.
