Waterproofing Paint

Waterproofing paint helps protect walls, floors, and other surfaces from damp, mould, and recurring water problems. Whether you're dealing with basements, wet surfaces, or rising damp, the right coating prevents water from getting in and keeps the surface in better condition for longer. Promain offers a range of waterproof coatings suitable for both internal and external use.

How Waterproofing Paint Works

Waterproofing paint forms a water repellent barrier over the surface. It stops moisture from penetrating through plaster, masonry, concrete or wood. Many coatings are suitable for wet or dry surfaces and can even be used where active water leaks have been a problem, depending on the product and surface preparation.

Benefits of Waterproofing Paint

  • Protects against moisture: Helps prevent damp, mould, and mildew forming on interior and exterior walls.

  • Improves durability: Coatings reduce dust pick up, resist dirt and reduce wear over time.

  • Works on various materials: Paint can be applied to brick, plaster, metal, plastic, wood, and more.

  • Versatile paint finishes: Choose from a smooth or non-gritty finish depending on the area.

  • Saves on maintenance: A good coating cuts back on repainting and prevents recurring efflorescence.

Types of Waterproofing Paint

  • Damp proof paint: Ideal for surfaces suffering from rising damp or condensation.

  • Concrete coatings: Portland cement-based solutions that resist water pressure in basements and cellars.

  • Clear or coloured options: Paints come in a range of colours and sheen levels, including bright white or gloss for a clean, professional look.

Waterproofing Paint for Walls

Walls - especially masonry or previously painted surfaces - need proper protection to avoid long-term damage. The first coat should always be applied to a clean surface free from contaminants like sand, dirt or dust. A good product will offer high adhesion even in slightly porous areas.

Waterproofing Paint for Bathrooms

Bathrooms are high-moisture environments where a solvent free coating is ideal for walls, doors, and trim. Paints with a non-yellowing finish are best suited for maintaining a clean look, and a water repellent barrier helps stop mould and mildew forming around baths and showers.

Waterproofing Paint for Concrete

Concrete walls and floors benefit from specialist coatings that resist pressure from water. Paints containing portland cement help cure the surface and seal small cracks, and are suitable for use in cellars, garages and foundations. A waterproof coating also helps prevent recurring efflorescence, which can damage the finish.

Waterproofing Paint for Wood

Waterproof paint for wood protects fences, gates, and decking from damp and decay. A solvent based formula may be used for higher durability, or a clear product to keep the natural look. Choose paint that is suitable for use on timber and compatible with previous coatings if the wood is already painted.

Waterproofing Paint for Roofs

Roof surfaces require coatings that can handle expansion and contraction due to weather. Coatings that stay flexible and resist dirt and UV damage are recommended. Ensure that the product has been tested for adhesion on wet or dry surfaces, especially if it's being applied over previously painted areas.

Waterproofing Paint for Showers

Shower walls need a tough waterproof coating with a smooth, non-gritty finish. It must prevent moisture from reaching plaster or cement backboards behind tiles. For best results, apply with a brush and allow the product to cure fully before exposing it to water—many can be cured immediately or within just four hours.

Clear Waterproofing Paint

Clear coatings protect without changing the appearance of the surface. They’re ideal for use on natural stone, brick, or previously painted decorative masonry. Products like Centrecoat R28 provide a transparent water repellent barrier that won't affect sheen or colour.

Recommended Products from Promain

  • Zinsser Watertite Waterproofing Paint: Designed for basements and walls, this damp proof paint resists water pressure up to 34 psi and prevents mould and recurring efflorescence with a bright white, non-yellowing finish.

  • Murfill Waterproofing Coating: A flexible paint coating that offers high adhesion to masonry, ideal for exterior house walls, and protects against moisture and dirt.

  • Murfill Quartz Waterproofer: Reinforced with quartz for added durability, this waterproofing paint is a good alternative for concrete or render surfaces needing extra strength and a non-gritty finish.

  • Centrecoat R28 Pure Sealer: A clear, solvent free water repellent sealer for stone, brick and porous surfaces that does not affect appearance.

  • Mapei Antipluviol W: A water-based coating suitable for external masonry. Provides a transparent barrier against rain, mildew and contaminants.

How to Apply Waterproofing Paint

  1. Clean the surface: Remove contaminants like dust, sand, and grease.

  2. Prime if needed: Some surfaces such as plaster or previously painted areas may need a primer.

  3. Use a paint brush or roller: Apply the first coat evenly. For rough or masonry surfaces, a brush works best.

  4. Allow drying time: Some products cure immediately, while others require just four hours between coats.

Maintenance and Durability

Clean painted surfaces regularly to remove dirt and mildew. Check for flaking or peeling areas and touch up as needed. Good maintenance helps extend the life of the coating and prevents rising damp or mould from returning.

Mistakes to Avoid

  • Poor prep: Skipping cleaning leads to weak adhesion.

  • Wrong conditions: Don’t apply to wet surfaces unless the paint allows it.

  • Not checking compatibility: Avoid applying solvent based paint over incompatible coatings.

Environmental Tips

Promain stocks solvent free and water-based coatings where lower VOCs are needed. Always read the product data sheet and dispose of leftover paint responsibly.

Cost Breakdown

Pricing varies by product, coverage and surface type. Higher-quality coatings save money over time by preventing water damage and reducing repainting needs.

DIY or Professional?

  • DIY: Works well on small interior jobs like bathrooms, plaster walls, or internal doors.

  • Professional use: Ideal for large masonry projects, high-risk wet areas, or surfaces with active water leaks.

Safety Tips

  • Use gloves and a mask, especially when applying solvent based coatings.

  • Work in a well-ventilated space.

  • Store all products safely away from heat, pets and children.
