    MasterSeal 588 is an elastomeric cement based waterproof coating for concrete and masonry

    How does MasterSeal 588 work?

    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 or roller. 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 Master Builders Solutions​ Technical Services Representative for further advice on the correct selection of mesh.

    MasterSeal 588 is suited to the following applications:

    • For waterproofing of water-retaining structures which may be subject to movement.
    • To protect concrete from water, carbonation and de-icing salts.
    • Suitable for internal and external use against positive water pressure.
    • Suitable for use in wet area waterproofing where tiles are to be installed directly on top of the membrane using a proprietary tile adhesive
