Reliable, long-lasting seals, with weatherproof expanding foam
Expands on application to fill cavities and then sets firm, with user reviews noting resistance to wet conditions. The weatherproof description and user feedback point to a formulation that keeps seals intact in damp environments.
Robust seals block draughts and moisture, reducing the need for repeat repairs and helping protect masonry joints.
Coverage for multiple jobs, with twin 500ml cans
Sold as a twin pack of 500ml cans, allowing separate repair tasks or a spare can for future use. Two cans give greater combined volume than single-can packs.
Convenient for homeowners tackling several small repairs, with enough material to cover more than one patch or to keep a reserve for later.
Blends with masonry, with stone-coloured formulation
Stone colour is specified in the product description, making the cured foam less conspicuous against brick or stone surfaces. Colour match reduces contrast compared with standard bright white foam.
Repairs are easier to conceal on stone or masonry, cutting down on visible patchwork and helping results look neater.
