Mastertop P 660 

Mastertop P 660 is a low viscosity, two component, solvent free, rapid curing, polyurethane primer which exhibits excellent adhesion to both concrete and to asphalt.

Mastertop P 660 is primarily intended for use as a primer for use on both concrete and asphalt substrates in certain carpark deck applications.  On concrete substrates, Mastertop P 660 is only to be used on suspended slab decks with a moisture content of less than 4% and where there is no risk of rising damp .
