Waterproof wall paint is a type of paint that resists water and humidity, consisting of resins, pigments, and additives that form a durable coating on the wall surface. It can be applied to a surface that either keeps water where you want it or out of where you don’t want it. This coating is a waterproofing membrane, which is a thick, flexible, and easy-to-clean material.
To make wood waterproof, remove paint and other coatings down to bare wood with sandpaper or strippers. There are three best options for waterproofing wood: oils like tung oil or Danish oil, synthetics like polyurethane, varnish, or lacquer, and natural wood oil like beeswax. Waterproof paint can cost more than standard varieties at $1 to $8 per square foot. Moist areas of the home may need to be sealed to prolong its life and preserve its color.
There are four best methods to make wood waterproof: using a natural, non-toxic sealant like beeswax, using a natural wood oil like beeswax, or coating most types of paint with clear polyurethane or acrylic. One way to make a water-based emulsion paint waterproof is to add a water-resistant agent, such as a silicone-based additive, to the paint. The safest method is to apply a primer beforehand and a sealant over the paint after finishing.
To prevent water seepage in your house, follow these 9 tips and techniques:
- Choose the right paint: Check for any damage before starting.
- Clean and prime the wall: Wash the walls with mild soap and warm water.
- Select the right paint: Choose the right paint, allow time to dry, apply multiple coats, and sand between coats.

How do you waterproof over paint?
Waterproofing paint can be achieved by coating it with clear polyurethane or acrylic, which can be as effective as spraying a sealant but may add a glossy or shiny finish. This can also add an amber hue, but this isn’t necessarily harmful as it blocks UV sunlight and protects the finish. If you want to use an interior paint outdoors, you can mix in a waterproofing additive like Paint Proofer to repel water and resist mold and mildew, or choose a paint with a waterproofing agent already mixed in.
How can I make my paint waterproof?
In order to render a water-based emulsion paint waterproof, it is recommended that a water-resistant agent, such as a silicone-based additive, be added prior to the application process. Alternatively, a clear waterproof sealant can be applied to the painted surface once it has dried.
How to waterproof a painting for outdoors?
To improve your home’s interior decor, consider investing in outdoor decor such as decks, patios, and balconies. Outdoor decor can increase curb appeal and provide better value for a house if it’s sold. Adding patterned throw pillows and colorful planters can make these spaces more inviting. Picture hanging can also revive lackluster brick or concrete walls. Durability is a priority when hanging artwork outside, as it exposes it to various weather conditions.
To do this, look for loose canvas at the sides and tape them down. If the canvas is white, cover it with newspaper and spray the entire front and back with clear acrylic sealer. If your art piece has a wooden frame, take it apart first.
Can I use vinegar to prep for paint?
Distilled white vinegar or baking soda are excellent non-chemical cleaning alternatives for wall preparation. Wearing rubber gloves during the cleaning process ensures safety. The initial sweep is crucial for removing loose dust and debris, which is essential for painting. Before starting, cover floors with tarps or old blankets to collect any falling dust. Choose the right dusting tool, such as a soft broom, a brush tied with a microfiber cloth, or a vacuum with brush attachments. Start from the top and work your way down the wall to ensure efficient removal of dust and cobwebs. Wearing rubber gloves throughout the cleaning process ensures a clean and safe environment.
How to seal paint for outdoor use?
To clean painted wood, mix TSP with warm water, lightly sand it, remove dust, and apply polyurethane sealer. Sand cured polyurethane can also be used. Applying more coats of polyurethane sealer can help preserve the wood’s appearance and prolong its lifespan. Sunlight’s ultraviolet (UV) rays are the main enemy of painted outdoor items, as photodegradation breaks apart the molecules that form the protective bond. Paint pigments, which absorb UV rates at a greater rate, also contribute to this destructive process. Therefore, it is essential to seal painted wood to prevent its degradation.
Can I put a water seal over paint?
Water Seal is a water-based paint that can be utilized on uncoated surfaces, such as brick, stone, or concrete, which have been left bare. The hydrophobic properties of the substance in question have the potential to affect the adhesion of paint. If applied correctly, the product can last up to four years, depending on the orientation of the wall in question and the prevailing climatic conditions. The product contains additives that reduce the formation of beads during application. Therefore, it is advisable to allow the surface to weather for a period of time before making a visual assessment.
Can you waterproof water-based paint?
To improve water-based paint’s water resistance, apply a waterproof sealant or varnish after drying. This can enhance its suitability for various conditions and applications. Waterproof water-based paint is particularly useful in humid areas like bathrooms, where steam and condensation can cause peeling or blistering. When combined with a waterproof primer, it blocks moisture, keeping walls clean. It also benefits interiors like kitchens, laundry rooms, basements, and kids’ rooms, as they can prevent damage and clean up mold and mildew.
How to seal water-based paint?
The application of polyurethane to a painted surface represents an effective method for the protection of paint. It is recommended that water-based products be used for color protection, as they do not undergo the same degree of yellowing as their oil-based counterparts. Polyurethane can be applied over any type of paint, provided that it is free of contaminants and prepared in accordance with the relevant specifications.
What to add to paint to make it washable?
Create your own washable paint by mixing dishwashing liquid, cornstarch, and food coloring in a bowl. Mix the ingredients together and pour into individual bowls. Add food coloring and use a paintbrush to mix it into the paint mixture. Paint on windows to spread cheer and let kids and adults paint whatever they want. Clean up is easy with a spray bottle of water and a washcloth, and window cleaner to remove streaks. This makes cleaning windows a win/win situation, as happy kids and clean windows are a win/win situation.
What can you add to paint to make it wipeable?
Most vinyl matt paints are washable, and a water-based varnish can be used to add additional protection against wear and tear. Polyurethane varnish is often used as an extra layer of protection. To make a vinyl matt painted wall wipeable, you can apply Polyvine Decorators varnish, which can be applied by roller or brush and takes 15-25 minutes to dry. However, most good quality vinyl matt paints can be used for wiping clean without the extra cost. Overall, using a water-based varnish can help protect the paint from wear and tear, making it a versatile and cost-effective option for wall painting.
What can I put over paint to seal it?
Solvent-based polyurethane sealants are more effective for sealing wood due to their stronger film. Other options include water-based polyurethane sealants, polycrylic sealants, and paint and sealer product combinations.

📹 How to Waterproof Bricks
How I recently waterproofed the exterior bricks of my cottage using a breathable, waterproof, self cleaning masonry creme from …
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.
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.
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 !
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.
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
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 👍🚀
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?
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!
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 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.
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.
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?
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.
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 !
