Waterproof Paint – Protective Coatings
Waterproof paints are essential in environments where structural integrity and long-term durability are at risk from persistent moisture. Designed for use on concrete, render, stone, and other porous building materials, these coatings form a water-resistant barrier that protects against surface breakdown and mould growth. Some formulations are flexible enough to accommodate movement and hairline cracks, making them ideal for detailing and remedial works in challenging spaces.
Within this category you'll find solutions for both interior and exterior surfaces, from walls and floors to basements, plant rooms, and balcony areas. In spaces like commercial food zones or prep areas, waterproof coatings may be applied alongside kitchen paint to withstand steam and frequent cleaning. Where penetrating damp is a recurring problem, compatible systems can be combined with damp-proof paint to deliver added moisture control. With options in smooth, textured, and breathable finishes, our waterproof paints can be applied by brush, roller or spray, and are tintable to match existing design schemes.
Waterproof Paints FAQs
Can waterproof paint stop active leaks?
No, waterproof paints are designed to prevent water ingress, not fix existing leaks. Leaks must be resolved before coating.
Is surface preparation important for waterproof paint?
Yes. Surfaces must be clean, dry, and stable. Use appropriate primers and degreasers where recommended.
Are waterproof paints breathable?
Some products are vapour-permeable, allowing trapped moisture to escape while still blocking liquid water. Always check the technical datasheet.
What types of surfaces can I paint with waterproof paint?
These coatings are suitable for masonry, concrete, render, brickwork, plaster, and more - depending on the product selected.
Can waterproof paints be used on walls with rising damp?
Not alone. Rising damp requires a proper barrier treatment such as a DPM or tanking slurry before applying paint.
Do I need a primer before using waterproof paint?
In most cases, yes. A suitable primer ensures proper adhesion and maximises the lifespan of the topcoat.
