Clear Concrete Sealer
Blockseal is an aqueous polymer sealant that seeps into the porous surface of floors and walls to create a transparent barrier against dust, oil and water. It helps to repel stains, algae, and environmental weathering. This non-toxic, fast drying coating has been specifically designed as a block sealer. A 5L pack of Blockseal will cover up to 30m2 of surface area depending on the substrate.
Chewing Gum Resistant
This clear sealer has excellent release characteristics that makes it much easier to remove chewing gum from paths and pavements. It is also resistant to stains from soft drinks like cola, coffee, motor oil, brake fluid and more. Blockseal will also repel water and dirt, helping to prolong the life of your blocks.
Suitable for Floors and Walls
can be applied by brush, roller or spray on both horizontal and vertical surfaces. This makes it great for driveways, beer gardens, smoking areas, cafe forecourts, retail locations and more.
