Ronseal Thompson One Coat Water Seal 2.5L

This product is designed for porous, unpainted surfaces like brick, stone, concrete, and wood. Applying it over paint may lead to poor adhesion or peeling.

The protection is designed to be long-lasting, but the exact duration can depend on environmental conditions and the type of surface treated. Reapplication may be needed after several years.

This product is specifically formulated for exterior use. For interior surfaces, consult products designed for indoor environments.

The coverage is approximately 4 square meters per litre. This can vary depending on the porosity of the surface being treated.

The approximate drying time is 2 hours. However, this can be influenced by ambient temperature and humidity levels.

The product can be applied to damp surfaces, but it should not be applied to standing water or excessively saturated surfaces. Allow excess water to drain off first.

No, it provides invisible protection and is designed not to alter the natural appearance or color of the treated surface.

This can indicate the surface is not porous enough or a previous treatment is still active. Test on a small, inconspicuous area first. Ensure the surface was properly prepared and free from contaminants.

Ensure consistent application with a brush or roller, avoiding overworking the product. Apply in a uniform direction. If streaks persist, a second *light* coat might be needed after the first has dried, though this is not typical for one-coat products.

This usually occurs if applied to a surface not suitable for water sealants or if the surface was not adequately prepared (e.g., still had dirt, grease, or loose material). Clean the surface thoroughly and reapply, ensuring proper prep.
