We had a Quick Paint Rate customer asking about rates for limewashing.


As you know, with your Quick Paint Rate licence you get full support, so if there is a rate you can't find,you can give us a call with the details and one of our painting estimators will supply the rate.


It's all part of your Quick Paint Rate licence.


Prior to applying make sure you dampen down the walls. Best thing for this is a garden pump action spray filled with water.


The limewash can only be applied by brush. You need a long haired, flat brush (wallop brush). Apply using criss-cross action.


Ensure that each coat is applied thinly:  Too thick and the limewash will crack.


Initially, you don’t see anything (the coating is ‘translucent’) and then as the coating dries, the colour appears.


Failing to control the drying will inhibit carbonation and compromise the success of the project causing issues such as shrinkage, hairline cracking, dusting and even delamination of the limewash.

AVOID rapid drying caused by direct, strong sunlight, winds or overly warm rooms.


DO NOT apply where the temperature is below 5 degrees Celsius and for a few days after this.


Allow 12hrs between each coat.


Coverage of limewash onto smooth lime plaster/render is around 3-4m2/L/Coat.


The min. number of coats is THREE: Externally, the minimum is 4nr. Coats.
