Mapei Planiseal 88 is a pre-blended powder, composed of a cement-based compound, selected graded aggregates and special synthetic resins according to a formula developed in the MAPEI research laboratories. When mixed with water, Mapei Planiseal 88 becomes a fluid mortar that can be applied by trowel, brush or by spray with excellent adhesion to the substrate for complete waterproofing, even in the presence of slight negative pressure.

Mapei Planiseal 88 can be applied with a brush, trowel or spray. For application by brush or spray, apply 2-3 coats to the perfectly cleaned and solid substrate which must be thoroughly soaked with water beforehand. When applying by trowel reduce the mixing water to 5-6 litres for each bag.
