Key Features

Waterproofs in One Coat: Our waterproof sealant creates an invisible, durable barrier designed to protect suitable surfaces against water ingress. One coat provides long-lasting waterproofing without changing the natural appearance of the surface, making Polar Clear Waterproofing Sealant ideal for everyday interior and exterior maintenance.

Protects a Wide Range of Surfaces: Our clear waterproof sealant is suitable for masonry, brick, stone, concrete, tile, grout and wood, providing transparent protection against moisture. Use around the home, garden and other suitable exterior areas where a discreet waterproof barrier is needed without covering the original surface.

Easy to Apply with a Brush or Roller: Ensure the surface is clean, dry and free from dirt, grease and loose material before application. Our clear silicone sealant waterproof formula can be applied directly by brush or roller, making it straightforward for DIY users to create a consistent protective coating without complicated preparation.

1m² Coverage per Litre: Our waterproof coating sealant covers up to 1m² per litre depending on surface porosity and application method. Touch dry in around 4 hours and fully cured within 12 hours, giving you reliable waterproof protection with minimal downtime for suitable interior and exterior projects.
