Applying Johnstone's Trade Stormshield Smooth Masonry

For best results apply using a brush, roller or spray to a clean, dry surface. Apply 2 coats, 2-4 hours apart in dry conditions where possible though it is rain resistant after just 20 minutes. 

If the surface has signs of fungal growth, clean first with a fungicidal wash. Stormshield Smooth Masonry can be applied directly to bare surfaces but if the surface is highly porous or friable, apply a coat of stabilising solution first.
