Johnstone’s Stormshield Smooth Masonry is a highly durable, water-based masonry paint that provides up to 15 years of protection. Rain resistant after just 20 minutes, it is a truly dependable exterior paint with excellent colour retention and high opacity. Offering coverage of up to 17m2 per litre, it can be used on cement rendering, rough cast, brick or concrete with ease. 

Highly resistant to dirt and stains, it is a favourite among trade professionals thanks to its durability and long life expectancy.

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.

If you're looking for an exterior wood coating with the benefits of the Stormshield, Demidekk offers superior protection.

Can Johnstone's Trade Stormshield Smooth Masonry be used on pvc gutters and downpipes?

We recommend applying Zinsser Bulls Eye 1-2-3 Primer before applying the masonry paint to the PVC surface to ensure adhesion.
