If you were to look at one of our paints you will always be able to find the SD Value and this is regardless of the brand, in fact if you look at competitors’ products they usually always state the SD Value of their paints, because they know they are offering a truly breathable paint.One of the main reasons for this failure is that a building can undergo significant movement, both structurally and thermally.Once a crack appears water can penetrate the crack and be held within the wall behind the non-breathable or waterproof coating, which can include cement and paint.This equates to moisture having to travel through the equivalent of 1 metre of air to escape.
The vast majority of paints can technically be classed as “breathable”, as they will eventually allow some moisture to escape.
There is no defined European Standard as to what constitutes breathability and there are at least 8 different ways to measure the breathability of a material.
