Captain Tolley's Creeping Crack Cure Sealant

Capt Tolley's Creeping Crack Cure Sealant is a one-part, water-based acrylic co-polymer penetrating sealant designed to locate and seal fine leaks in hairline cracks, joints and hard-to-reach gaps. The sealant is thinner than water, allowing it to move by capillary action into cracks and joints that conventional surface sealants may not reach.

As the sealant is absorbed into the leaking area, it helps identify the source of the leak. Once cured, it forms a clear, flexible seal that accommodates movement when dry.

What is this sealant used for?

This penetrating sealant is used to seal small leaks in homes, boats and caravans. It is suitable for cracks, joints, fittings, trims, surrounds and ageing materials where water ingress occurs through fine gaps.
