FAQ
What's the difference between a damp-proof membrane and a waterproof coating?+
A damp-proof membrane (DPM) is designed to prevent moisture *rising* through brickwork, acting as a barrier. Waterproof coatings, on the other hand, create a surface layer that repels water from *external* sources, preventing it from penetrating the wall. Using them together provides comprehensive protection.
How much preparation do I need before applying a waterproofing coating?+
Thorough preparation is vital for optimal adhesion and performance. This includes cleaning the substrate with a suitable cleaner, removing loose paint or existing coatings, and ensuring the surface is dry before application – typically 24 hours after cleaning.
Are these products suitable for use on concrete walls?+
Many of our mid-range options are compatible with concrete, but always check the manufacturer’s technical data sheet. Some may require a primer to ensure proper adhesion and long-term protection against alkali attack in the concrete.
What tools will I need for applying a membrane?+
For applying membranes, you’ll generally need a taping knife or smoothing tool to create a seamless barrier. A measuring tape is essential for accurate cutting, and a sharp utility knife provides precise edges – always use caution.
How do I calculate the area I need to cover?+
Accurately measure the surface you intend to treat in square meters. Multiply this by the coverage rate specified on the product's technical data sheet to determine how much product you’ll require for your project – always buy a little extra for overlaps.
Can I apply these products to exterior walls?+
Several coatings are designed for external use, however, check the manufacturer’s specification carefully. Ensure compatibility with existing paintwork and consider weather conditions during application for best results.
What kind of surfaces can these membranes be applied to?+
Most breathable DPMs are suitable for brick, blockwork, and rendered walls. However, always verify the manufacturer’s suitability data sheet before commencing work, particularly with unusual substrate types.
How long does a waterproofing coating typically last?+
The lifespan of a waterproof coating depends on factors such as application quality, environmental exposure, and maintenance. Regular cleaning and occasional reapplication may be needed to maintain its protective barrier over 5-10 years.
Are these products suitable for preventing condensation?+
While waterproofing prevents external water ingress, our membranes are breathable, allowing moisture vapour to escape from within the wall cavity. Combining this with good ventilation helps manage internal humidity and reduce condensation risk.
What should I do if the product doesn't adhere properly?+
Ensure the substrate is clean, dry, and free of loose particles. If adhesion remains an issue, consult the manufacturer’s technical support for advice – a primer may be necessary or underlying damage needs addressing before application.
