An aqueous penetrating capillary solution that provides surface protection and up to 2mm in-depth impregnation of the substrate.

Sealer 405WB reacts with the interfaces in pores and capillaries of the mineral surface and forms invisible water-repellent interfacial compounds.

Except for cracks and structural flaws, Sealer 405WB will protect the concrete from water seepages; leaving the original appearance unchanged.

Suitable for use on: Concrete, Cement Fibre Board, Brick (end wall)
The amount required is dependent on absorbance of substrate and desired penetration depth. For maximum absorption into substrates, up to 1 litre per square meter may be required
