Painting exterior brick traps moisture inside the masonry, which can damage bricks and any paint covering them. Certified chimney sweeps and masons do not recommend painting chimneys to stop water from entering. When choosing masonry paint, consider the level of protection you want. For example, waterproof masonry paint like Emperor can keep exterior walls dry and keep your home 6°C warmer. However, it should not be used on floors and does not stop floor seepage or leaks.
Outdoor masonry paint acts as a protective barrier, shielding walls against harsh weather conditions such as intense sun exposure, heavy rain, and cold temperatures. This added protection helps prevent external damp issues. If you are looking to paint over areas of exterior masonry that have had paint fail, understand why to ensure it does not happen again.
The stabilizing solution or primer is a common topic in exterior wall paint. Normally, masonry walls can be primed with a thinned solution of water-based masonry paint. However, sometimes, the surface can peel, leading to failure. To address this issue, remove as much peeling paint as possible.
To waterproof exterior foundation walls, use DRYLOK Original Concrete and Masonry Waterproofer, a versatile formula that can be applied to approved interior and exterior surfaces. Standard masonry paints do not prevent this absorption, as they are often acrylic-based masonry paint. Acrylic masonry paints absorb some moisture, making them “weatherproof” or “weather resistant”.
Dri-lok is a great product for painting unpainted masonry, but cracks must be repaired. The brick wall coating acts as a brick waterproofer and helps prevent water ingress, causing dampness. If you need to waterproof exterior brickwork, apply a sealer to trap moisture inside the property. Sandtex masonary paint is top-notch, waterproof, and flexible, as long as it is put onto a good base (the Satabliser solution first).

When not to use masonry paint?
Masonry paints are water-based and should not be applied below 10C due to their potential freezing and peeling. They are heat-resistant, but the specific formulation depends on the location. In the UK, basic masonry paint can handle both summer and winter temperatures, but in countries like Spain, a heat-resistant formula may be needed. This type of paint can expand and contract with bricks, preventing cracking, flaking, and chipping. Masonry paint can protect homes from dampness, rot, and chemical effects, reducing their attractiveness, energy efficiency, and resale value.
It also acts as a physical impact barrier, preventing damage from small stones and other minor hazards. Masonry paint can be used to protect homes from dampness, rot, and chemicals, enhancing their energy efficiency and resale value.

What are the benefits of masonry paint?
Masonry paint offers six main benefits for property owners: airborne pollution protection, algal growth prevention, efflorescence protection, crack prevention, spalling treatment, and blistering prevention. It is particularly beneficial for properties near coastlines, where salt (chloride) can damage walls and structures. EcoSpray-Foam Systems offers two types of masonry paint, secoFLEX and secoTHERM, which provide protection against water damage, mold, chloride, algae, dampness, and more. These paints can help prevent airborne pollution, prevent algae growth, prevent eflorescence, prevent cracking, spalling, and blistering.
What are the disadvantages of drylok?
Brian Jeffries, a seasoned BPA Advisor, shares his knowledge on construction projects and materials, focusing on architecture and building envelopes. When looking for waterproofing solutions, there are many options available, including Drylok, XYPEX, and Damtite. However, it’s important to note that these brands and materials are not created equally, and some can perform better than others. Drylok is a waterproofing product that can be used on frozen surfaces and in temperatures under 48 F.
It sets quickly, needs to be used within 10 minutes, and is the most expensive option. It’s crucial to choose the best option for your project, as it can be challenging to determine which product is best for your needs.
Does masonry paint keep water out?
Masonry paints like Dulux Weathershield provide some weather protection but are not 100% waterproof. They are designed to remain attractive without peeling or flaking but do not completely prevent water from soaking into the brickwork. Emperor Paint, an advanced masonry paint, creates a super hydrophobic surface on exterior walls using nano-technology to repel water off the surface.
When choosing a waterproof masonry paint, it is crucial to ensure it is breathable. Breathability refers to the ability for water vapor to transfer through a paint, which is crucial for a masonry paint. If a paint is waterproof but not breathable, moisture trapped within the property will cause significant damp issues. Therefore, it is essential to choose a paint that not only offers weather protection but also prevents moisture from escaping the property.

Will masonry paint run in the rain?
Acrylic masonry paints are the most prevalent type of masonry paint utilized in the United Kingdom. They are water-based and possess weatherproof properties. These paints have low breathability and a lifespan that ranges from one year to fifteen years. Such products are available from leading manufacturers, including Dulux, Crown, and Sandtex. Silicone masonry paint represents a technologically advanced coating material comprising silicone resins treated in a manner analogous to that of a water-based paint.
📹 How to Waterproof Bricks
How I recently waterproofed the exterior bricks of my cottage using a breathable, waterproof, self cleaning masonry creme from …
Personally I think these treatments have their place in solving a problem but that problem will stem from using porous bricks in the splash courses (i.e. below DPC level) and secondly from using a cementitious mortar with porous bricks. I’m not one of the “breathable/nothing but lime mortar” fanatics but I certainly recommend looking at the advice offered from The Brick Development Association when it comes to specifying brick and mortar type selection. They have a great leaflet on Severely exposed brickwork that’s well worth a read.
Charlie Love the content but I have a question for you. I have a neighbours retaining brick wall that sits about 5ft higher than my path separating their property from my garage. Obviously over the years th we e had been an awful lot of water ingress that leaves my side looking damp and looking ready to lose its facing. So my question is how do I protect the bricks?? Is this crème suitable? Or can you suggest an alternative please? Regards Alan
Thanks for this Charlie, again a product I’ve not come across before, so interesting to be made aware of its existence. I live in a relatively modern property so luckily don’t feel the need to apply this as from their guidance it would cost me around a grand for the whole house. There are however a few places that routinely get and stay damp, so I may just try a tester on some small areas to see how it performs over time ! I wish people would double check what you’ve said, before charging in to criticise in the comments, it gets very tedious ! Be assured most of us appreciate your content, but still take personal responsibility for our own actions and do further research before deciding whether to follow what you’ve advocated or not as the case may be !
I used a similar product on this gravel render i have on my house in the med, it was from Sovereign Chemicals and is called weather check, about the same price and looks similar, it defiantly works, i have had it on for over 10 years and you can see how quickly my house drys out after rain compared to my neighbours with the same finishing. and yes its breathable.
Hi Charlie, thanks for sharing – really helpful article as always. I’m guessing this wouldn’t be affective on an already painted wall as the brick wouldn’t be able to absorb it effectively? Do you have any tips on how to treat an already painted wall (red brick) or is it a case of stripping the paint back and starting again from scratch?
I plan on doing something similar for my lower bricks of my 20’s house including repointing, the other issue I have is water bridging across below ground level. In my sitting room if i lift the boards its soil, and in the bottom 1/4 there is water which doesn’t stand but does increase when it rains and I can see the water coming through the bricks below the external ground level. I don’t know wether just to dig down in stages and apply a sealant, or to attach an external membrane to the wall and poor a deep concrete skirt below ground level around side of the house that gets the water. I’m unsure how deep the footings are though.
Hi, any advice on removing old paint and applying new breathable paint? We are buying a house and we are aware of few issues of the old paint being cracked at places and potentially being not breathable. Any advice on what product/approach to use to remove the old paint the easiest way and then what product to apply. Thank you in advance!
Can this be applied on interior brick or breezeblock behind plasterboard? Ive had a leak from a roof and its tracked down the cavity wall between mine and my neighbours house but water was coming in on my side and the breeze block is a bit wet. Will let it all dry out but want to use a sealant of sorts to ensure no moisture will result in damp or mould issues. Any help or advice would be gratefully received.
Great article, I need some advice please, I have a brick built lock up which the rear brick wall faces a railway embankment and is north facing, this wall is showing damp patches through to inside! How would you go about preventing further damp ingress through this brick any particular product, the unit is heated during winter. Keep up the good work 👍🚀
We are getting cold/ damp bridging inside our conservatory, which is built onto the garage, so the exterior wall of the garage is the interior of the conservatory on the other side of the window if that makes sense. The wall in question is rendered and painted, could this creme or other water seal be applied over this finish to prevent the damp cross bridging the window?
Great article Charlie, thanks. Does this product work below ground? Found damp entering unpointed bricks just above the footings, a leaking cement down pipe hopper contributing to the problem and hiding the location. Solid Stock brickwalls, (1934 build). The location is to be covered below ground once treated.
Nice informative article, thinking about using Storm dry which is a similar product. I only have 2 questions… 1) Will this keep the house warmer in winter? Of course you cant beat insulation but a dry wall is warmer than a wet wall when the wind hits it.. 2) Can i use EWI on the wall in future after waterproofing it?
Great job Charlie. This masonry cream is great. I have an old house (built 200 years ago) with hand made porous bricks. I used Sovereign ‘Weather-Chek’ facade cream, which in all fairness looks identical to the cream you used. My bricks did go very dark in colour once applied, but this faded in 2-3 days. It’s not cheap, but a great barrier from the elements. Also has a life span of up to 25 years, which is way better than the clear water seal type liquids which only seem to last a year or two. It’s a good job you covered your patio area, I got some spots on a my stone path and still have marks two years later.
I love what you do in your articles but honestly feel this is misguided. Traditionalt built (mostly pre WW2) Brick and Stone built buildings need to breath or you will trap water and push it inside. Cement mortar also seals in damp and causes problems. Please dont take my word for it but have a google and avoid making expensive mistakes. Best of luck with the works !
