When discussing brick sealers and sealants, it's important to note that a brick sealant is a type of water repellent applied to brick, stone, or concrete surfaces to create an invisible waterproof film that prevents water absorption and protects the material.
Clear sealants offer zero visibility, no toxic fumes, water repelling and, once dry, help maintain a clean and natural looking surface. They resist liquids, prevent stains and can even prevent chewing gum from sticking to the surface. Because all of our clear sealants are breathable, they allow for water repellency within hours of the product being applied. This means that the sealants we offer can be used in all weather environments, inside or outside.
Sealants are environmentally friendly and are proven to be very effective for over 10 years. The right sealer will protect the surface's natural appearance, all the while offering outstanding protection against water, chemicals, dirt and sunlight.

Interior Brick Sealer
If you're sealing interior brick walls in living rooms, kitchens, or around fireplaces, Promain has options that reduce dust, protect against stains, and remain breathable. Ideal for porous bricks and older properties, these products preserve the natural look while allowing moisture vapour to escape. Use a paint brush, low pressure sprayer, or spray gun for an even coat. Always apply appropriate safety wear and avoid direct sunlight during curing.
Wall Brick Sealer
Whether you’re working on exterior walls, facades, or exposed brickwork, our breathable brick sealer range includes solutions for protecting against rain, frost, and penetrating damp. Applying protective treatments to the exterior wall is essential to prevent moisture ingress, damp issues, and damage, which enhances both the durability and appearance of the surface. These impregnating coating systems sink into the surface, blocking water ingress without trapping moisture. Perfect for mid terrace houses, large dressed sandstone blocks, and any exterior brick surface that needs long-term protection.
Clear Sealant Range
Promain’s clear sealants are suitable for both interior and external walls. Our solvent free formulas remain breathable, won't yellow over time, and offer a stain resistant surface. They're easy to apply using a roller or brush, quick to recoat, and reduce long-term cleaning costs. Surfaces treated maintain their appearance, resist organic growth, and can help solidify jointing sand in paved areas.
Clear Sealant Spray
Spray sealers are ideal for uneven surfaces, joints, and edges. Perfect for steps, thresholds or areas where a brush won’t reach. Use a low pressure sprayer or spray gun to ensure complete saturation. Each unit offers a high surface average coverage - up to 20 m² - making it practical for exterior paths or smaller sections of masonry.
Clear Waterproof Sealant
Promain’s clear waterproof options are designed for outdoor use on brick, masonry, cement and concrete. These sealers penetrate porous surfaces deeply to prevent water ingress, mould, and further erosion. They help block organic growth stain while keeping the treated surface breathable. Apply on fully cured surfaces and store sealed in a cool, dry place after use.
Choosing the Right Sealant for Each Surface
Choose a masonry sealer based on location and surface type. Water-based sealers work best indoors or where breathability is key, such as on interior brick sealer jobs. For outdoor work, like exterior brick sealer applications or concrete walls, solvent free impregnating sealer products are preferred. They’re effective at resisting both oil and water, and don’t form a visible film. Some are also compatible with monocouche render systems and cement-based substrates. Masonry cream is another option, offering a breathable, water-repellent treatment that penetrates mineral surfaces like brick and stone for long-term durability.
Benefits of Breathable Sealants
A breathable sealer helps porous surfaces absorb moisture and release it gradually, avoiding trapped moisture issues that cause blistering, peeling or flaking. Ideal for heritage brickwork, specialist bricks, or any masonry surface providing ventilation. These products are especially useful where penetrating damp or rising damp is a concern.
Masonry creams are long-lasting, water-repellent treatments for masonry surfaces, and for best results, they should not be mixed with paints or other sealers.
Environmental Responsibility
All sealants sold by Promain meet strict environmental standards. Our low-VOC formulas are safe for indoor use and won't release harmful vapours. They’re suitable for use around children, pets, and in rooms with poor ventilation. Internal jobs should still follow all safety data guidelines, and surfaces should be completely cured before returning to normal use.
How to Apply Clear Sealants
-
Clean the area thoroughly - pressure washing external walls helps remove dirt and loose material.
-
Ensure the surface is completely dry before applying any sealant to achieve optimal adhesion and durability.
-
Allow the surface to completely cure - usually 24 hours minimum.
-
Use appropriate safety wear when handling or spraying.
-
Apply with a paint brush, roller, or low pressure sprayer in even strokes. For optimal protection, apply two coats, following product instructions for drying time between coats.
-
Avoid walking on treated surfaces for 24 hours; heavy use after 48 hours.
Do a few tests in small areas first to check absorption rate and finish - especially for film forming products that may leave a sheen.
Maintenance Advice
Gently sweep or low-pressure rinse every few months to extend the life of the seal. Watch high-wear areas such as doorsteps or driveways and recoat when needed. Most sealed brick or masonry surfaces can last 5–10 years between treatments with correct care.

Frequently Asked Questions:
What do you use between concrete and brick?
Use a flexible masonry-grade sealant or joint filler that can handle movement and thermal expansion.
Can you use concrete sealer on brick?
Only if it’s suitable for both. Most concrete sealers are too dense for brick. Use a breathable, penetrating product designed for porous masonry.
Is it worth sealing bricks?
Yes. It reduces water ingress, stops moss and algae, and cuts back on future maintenance.
What’s the best sealant for brick?
Promain recommends breathable, impregnating sealer options like Centrecoat R28 Pure Sealer or Mapei Antipluviol for exterior brick, and Bedec Interior Brick Sealer for inside walls.
