WATERPROOF SEALANT
Liquid Rubber Waterproof Sealant is quite literally a liquid rubber that can be applied like any normal paint to most common surfaces to waterproof and protect surfaces. Due to it’s amazing adhesion to almost any substrate, it is the most universal sealer and protector for all craftsman and kiwi DIY’ers.
Once applied to a substrate, Liquid Rubber acts as an adhesive and bonds extremely well to the substrate, curing to form a highly flexible and seamless rubber membrane that prevents water infiltration and stops rusting and corrosion. This seamlessness means there are no joins, which is where traditional waterproofing methods can fail.
