FAQ
What type of surfaces can Ronseal Damp Proofing & Waterproofing be applied to?+

How many coats are required for optimal protection?+
Typically, two generous coats are recommended for maximum effectiveness. Allow sufficient drying time between coats as per the product instructions – usually 12-24 hours depending on environmental conditions.
What preparation is needed before applying the coating?+
Thorough surface preparation is key. This includes removing loose mortar, cleaning with a suitable cleaner to remove dirt and contaminants, and potentially chasing joints for better penetration.
Can I use this product on exterior walls?+
Yes, but it’s specifically formulated for exterior applications. Ensure the wall is clean and dry before applying, and consider using a breathable paint afterwards for added protection.
How long does it take for the coating to dry?+
Drying times vary depending on weather conditions (temperature and humidity). Typically, it takes 12-24 hours between coats and 72 hours before redecoration. Always check the product data sheet for precise details.
Is Ronseal Damp Proofing & Waterproofing suitable for use in a damp basement?+
Yes, this coating can be used in basements but it's crucial to address the underlying cause of the dampness – rising damp or condensation. Proper ventilation is essential alongside application of the product.

You’ll need a brush, roller and possibly a sprayer depending on the surface area you're covering. Ensure your equipment is clean to avoid contaminating the coating.

When applied correctly, it allows for some breathability, preventing moisture build-up within the wall structure. However, always ensure adequate ventilation after application.
