Johnstone's Trade Stormshield Pliolite Masonry
Best for: Painting when the weather won't cooperate or time-sensitive jobs that can’t wait for a dry spell.
When the weather won’t wait, the Johnstone’sTrade Stormshield Pliolite Masonry finish lets you get the job done come rain, wind or snow. This specialist exterior paint uses advanced Pliolite® technology to deliver excellent adhesion and durability.
It can be applied in temperatures as low as -5°C and is shower-resistant in just 20 minutes. That means less worrying about sudden weather changes and more confidence in getting the job done right.

Johnstone’s Trade Stormshield Aqua Guard Exterior
Best for: Exterior wood and metal trim like doors, windows, soffits and fascias, especially where low odour and a fast turnaround are priorities.

This low-odour, fast-drying paint is ideal for time-sensitive projects and delivers up to 8 years of dirt, weather, and stain resistance in a flexible, microporous finish.
The flexible coating helps resist cracking and peeling, making it suitable for exterior joinery such as doors, windows, and trim exposed to changing temperatures.
This range includes a high-performance exterior primer undercoat, as well as Aqua Guard Satin and Aqua Guard Gloss finishes.
Johnstone’s Trade Stormshield Flexible
Best for: Window frames, doors and trim that are subject to significant movement and expansion, where long-term durability is the priority over fast drying.
The Johnstone’s Trade Stormshield Flexible range is designed to deliver long-lasting protection for exterior wood and metal, including windows, doors and trim.
Formulated with advanced microporous technology, these flexible coatings move with the substrate, helping resist cracking, peeling and blistering. This makes it perfect for areas exposed to frequent temperature changes, helping maintain a smooth, professional look over time.
Available finishes include:
Johnstone’s Trade Stormshield Stabilising Solution
Best for: Preparing highly porous or unstable exterior masonry surfaces before painting.
The Johnstone’s Trade Stormshield Stabilising Solution is an essential preparatory product designed to stabilise surfaces before applying masonry coatings. It works by penetrating and binding defective areas, such as chalky, powdery or weathered substrates, creating a sound base for paint application.
Ideal for exterior use on cement rendering, brick and concrete, this solution improves adhesion and helps ensure a consistent, lasting finish. It’s particularly useful when working with older or weathered surfaces that may otherwise affect the performance of your chosen Johnstone’s Trade Stormshield topcoat.

FAQs
Johnstone's Trade Stormshield can be used on most exterior masonry surfaces, including brickwork, concrete, rough cast and cement rendering. Some products within the range are also suitable for use on exterior wood and metal, particularly the satin and gloss finishes.
Yes. Proper surface preparation is essential for achieving the best results. Before application:
-
Ensure the surface is clean and dry before beginning.
-
Remove any loose and flaking paint and repair defective areas.
-
Treat fungal or algal growth with a fungicidal wash.
It may be worth getting some filler to repair cracks, larger holes and gaps on the wall, which would still show after being painted over. For highly porous or unstable areas, use Johnstone's Trade Stormshield Stabilising Solution to help stabilise surfaces and improve adhesion.
The Stormshield Smooth Masonry formula is not breathable, meaning it won't allow moisture to escape once applied. For most modern brick or rendered properties in good condition, this isn't a problem. However, it's worth choosing a specialist breathable masonry paint instead if your property has:
-
Solid walls (typically pre-1920s, no cavity)
-
Lime render or lime plaster
-
A history of damp or moisture ingress
-
A previously breathable coating on the walls
If none of the above applies, Stormshield Smooth Masonry is an excellent, long-lasting choice for your exterior walls.
