Hydrostop 401

Hydrostop 401 is a product designed for plastering and sealing holes, voids, cracks, joints, and seams. It can be used as a waterproof plaster on walls made of concrete blocks, concrete, and brick, without salt efflorescence. The mortar is applied in areas where water does not flow out during sealing. It is intended for use both internally and externally in residential, industrial, and public utility construction. The product is non-flammable. For sealing monolithic concrete structures, Hydrostop Professional Mixture should be used, and for water flowing under pressure, Hydrostop-Fix is recommended. Hydrostop 401 should not be used on marble. If mineral salt efflorescence appears on the wall, Hydrostop Injection should be used. Waterproof plasters for large surfaces are usually applied using Hydrostop Plast.
