MasterSeal 588 - An elastomeric cement based waterproof coating for concrete and masonry

Formerly THOROSEAL FX100


MasterSeal 588 powder is a blend of Portland cements, selected silica sands and modifying agents. When mixed to a slurry consistency with MasterSeal 588 liquid, an acrylic polymer emulsion, it can be easily applied by brush, roller or spray equipment. It cures to give an elastomeric flexible membrane that remains flexible even when submerged.

MasterSeal 588 must be reinforced with mesh across all construction joints and cracks. The reinforcing mesh may be either 100% virgin polypropylene or alkali resistant glass-fibre mesh depending on the properties required, please consult your local BASF Technical Service Representative for further advice on the correct selection of mesh.
