Remember, even the best exterior masonry paint suffers from improper application. Our guide to the best paint brushes in the UK helps you choose the right products for edging, detailing, corners and small surfaces.

It’s the most expensive per square metre, there are question marks about its durability, and it only comes in two colours. Also, be aware of allergies before splashing out on certain products. Some masonry paints contain acrylates, which can trigger severe allergies. This blog post has plenty of information on why acrylates are harmful and how to avoid them. Sandtex® Microseal® masonry paint is microporous and provides sealing attributes that protect the coating against water ingress. This means that the coating allows the surface to breathe and moisture to evaporate whilst at the same time protecting the coated surface from water penetration.

Choosing between the Crown and Rustins offerings is harder. The latter is touch-dry within half an hour, which is highly impressive, especially for outside work in autumn or winter. However, it comes at the cost of acrylic composition, which may put off people who suffer from related allergies.
