## Description

Anthracite Grey Construction Sealant & Adhesive All-In-One Hybrid Polymer | Superior to Silicone Sealant | Waterproof, Odourless, Anti-Mould, Paintable | Kitchen Bathroom Outdoor - 300 ml 3 Pack : desertcart.co.uk: DIY & Tools

Review: Works great, waterproof when used externally - Plugged the hole i needed it for. Waterproof and hasnt leaked so i assume its good quality and durable. Straightforward to use simply insert into silicone gun and snip the end off. Colour is indeed jetblack.
Review: TOP QUALITY - Good stuff, stays a bit tacky for a while. Best to line each side of the gap to be filled, if possible, with masking tape. Remove the tape after you filled and levelled it or the tape might stick to the filled edge.
