Cohe Waterproof Sealant Black 4L


Liquid Rubber Waterproof Sealant is a water based alternative to conventional hot applied or solvent based waterproofing systems.
It is applied as a liquid then when cured, forms a flexible elastic membrane able to withstand stresses and vibrations without cracking or peeling from the surface.
As a permanently flexible and seamless coating, Liquid Rubber Waterproof Sealant produces a fully adhered chemical waterproof coating that resists cracking and ageing.

4-8m² coverage for 2 coats – Please allow an extra 0.5L/sqm for concrete or rough/porous surfaces

Liquid Rubber Waterproof Sealant is 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 Waterproof Sealant 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.
