MAPEFLEX PU55 SL
One-component polyurethane sealant for joints subject to lengthening of up to 7.5% when in service.
Applications:
Flexible sealing of joints (distribution joints, isolation joints, check joints, etc.) in internal and external floors in ceramic, stone, concrete, wood, etc., in areas subject to intense, heavy traffic such as warehouses, car parks, supermarkets, etc.
N.B.: Mapeflex PU55 SL generally adheres well to non-absorbent surfaces. However, to improve adhesion at the edges of the joints, we recommended that they are pre-treated with Primer M. Then wait from 30 minutes to 5 hours, until the primer is no longer sticky, before sealing the joints with Mapeflex PU55 SL.
