SEAL iT is a new generation water-based fluoropolymer impregnation sealer designed to give up to 5 years oil and water repellency to porous wall & ground surfaces.
For professional-grade protection on your concrete, masonry, and paving projects, the Protect-It Seal-It 5L is a reliable trade and DIY solution designed to enhance durability while maintaining the natural look of your surfaces. This water-based sealer penetrates deep into the substrate, providing long-lasting resistance against water, oil, and dirt — perfect for patios, paths, driveways, and garden features.
Its easy-to-apply formula ensures quick coverage, allowing both tradespeople and DIYers to get the job done efficiently while protecting surfaces from the Irish climate.
