The ultimate paint for brick and stone
Emperor Masonry Paint is the next generation of paint for brick and stone, engineered to let your walls breathe and protect the surface beneath, proven to last at least 25 years and backed by a lifetime guarantee.
Moisture is the enemy of brick and stone
Like a sponge
Brick and stone are porous, meaning they absorb rain. That moisture can often soak into your home, causing damp and damage.
Needs to breathe
That moisture needs a way out. Block it and it gets trapped inside, eventually forcing its way through and damaging itself.
Paint often doesn't do both
From limewash to standard masonry paint, most paint for brick and stone makes a trade-off between water resistance or breathability. Your walls pay the price either way.
The trade off no one tells you about
When water gets into brick and stone it causes a range of problems for your walls. It gets into the wall, builds up behind the paint and eventually causes it to peel and flake, driving damp into your home.
So the instinct is to seal it, but trap moisture inside a wall and you get the same problems from the other direction.
Traditional paints and coatings force you to choose, keep rain out or let the walls naturally breathe.
- Limewash – highly breathable, but very little water resistance
- Oil-based masonry paint – high water resistance, but very low breathability
- Standard masonry paint – offers some water resistance and some breathability, but not enough of either. Water still gets in, moisture still gets trapped and the paint can still peel
Paint brick and stone without the compromise
Your home is asked to accept a compromise – keep water out or let walls breathe. On exposed homes, that compromise shows up as damp, peeling paint and wasted time and money.
But you don’t need to choose anymore. With our cutting-edge nano-technology, you get the best of both worlds.
How it works
Keeps rain out
Within Emperor Masonry Paint there are millions of microscopic pyramids with tiny gaps between them.
When rain hits, it only touches the tips, so it can’t spread or soak in, reducing water absorption by as much as 96%.
Lets walls breathe
At the same time, those same gaps allow water vapour to pass through.
A droplet of rain is millions of times larger than a molecule of water vapour, so while rain is too large to get in, water vapour is small enough to move through the surface.
That means it stays highly breathable, with an SD breathability value of 0.03, similar to limewash and well below the 0.5 often considered ‘breathable’.
Tested. Proven. Guaranteed.
It’s easy to make claims, but we believe in proving them. Every benefit we talk about has been independently tested by a world leading laboratory.
Most importantly, after 25 years of harsh weathering, it showed no change in performance or appearance. That’s why we’re so confident in it, we back it with a lifetime guarantee.

Frequently asked questions
Can you paint silicone render?
Yes, you can paint silicone render using the correct paint, which must be a silicone-based masonry paint.
What paint should you use on silicone render?
Silicone render isn’t a typical surface. With added resins to the formulation to provide it with water repellent properties, applying a standard masonry paint which are often acrylic-based will result in compatibility issues and potentially peeling paint. Alongside this, using a standard masonry paint will allow reduce breathability and remove water repellent properties, impacting the performance benefits that a silicone render provides.
In order to maintain this performance and ensure the paint can adhere properly to the silicone render, you need to use a silicone-based masonry paint like Emperor Masonry Paint when painting silicone render.
How long does masonry paint last on silicone render?
Providing you have used a suitable paint, how long a paint lasts depends on the paint itself. Emperor Masonry Paint lasts a minimum of 25 years on silicone render without peeling or flaking, which is why it comes with a lifetime guarantee.
How do you prepare silicone render for painting?
In order to paint silicone render, you must ensure the surface is clean and sound.
Firstly, wash the masonry down with a pressure washer (on a low pressure), hosepipe or a stiff brush and hot water. Then apply a fungicidal cleaner to the wall where there are problems with organic growth.
If there are any cracks or holes in the wall, make sure you fill these with a good-quality exterior filler. If there is any peeling paint, remove this using a paint scraper back to a ‘firm edge’, where no more paint can be removed.
