Product Code:  KATALYST180

The MARISEAL® KATALYSATOR is an accelerating additive for use with the MARISEAL® 250 / 260 liquid-applied polyurethane waterproofing membranes.


The MARISEAL® KATALYSATOR accelerates the MARISEAL® 250 / 260 allowing it to cure homogenous, at a quicker rate, even at low temperatures, so an overcoating is possible within 3-5hours. The MARISEAL® KATALYSATOR enables the MARISEAL® 250 / 260 to be applied in any desirable thickness, without forming bubbles


The MARISEAL® KATALYSATOR is mainly used when the MARISEAL® 250 or 260, needs to be overcoated within the same day of application or when the MARISEAL® 250 or 260, needs to be applied in higher coating thicknesses in one layer. The MARISEAL® KATALYSATOR accelerates the MARISEAL® 250/260 waterproofing coating for:

  • Waterproofing of Roofs
