Thompson's One Coat Water Seal - 5L

The Ronseal Thompson's One Coat Water Seal is a high-performance waterproofing solution designed to protect brick, concrete, stone and wood surfaces with a single coat. It uses a unique micro silicone emulsion to prevent water penetration and the damage that can follow freeze–thaw cycles. The product is formulated for easy application and can be applied directly to damp surfaces, delivering long-lasting protection within hours. Suitable for use on a variety of masonry and timber substrates, it helps reduce efflorescence and provides a clear finish. This 5 Litre container covers approximately 4 m² per litre, enabling you to treat larger areas efficiently. The coating dries in about 2 hours and can be applied with a brush or roller, making preparation and application straightforward on walls and other protected surfaces.
