MasterTop P 650 is a high grade; low-viscosity, two-component epoxy primer and surface sealer. MasterTop P 650 is used as a sealer or scratch coat with, and without, the addition of quartz sand.
Where is MasterTop P 650 applied?
MasterTop P 650 is suitable for the sealing of concrete surfaces, as well as for the filling of fissures and joints. To improve adhesion MasterTop P 650 is sprinkled with quartz sand while still wet to create a mechanical key for subsequent coatings.
MasterTop P 650 may be mixed with sand to the desired consistency to repair patches or form covings. In either case the mixed mortar must be applied to a surface previously coated with MasterTop P 650 resin and whilst still tacky.
Note: Refer to the Method Statement for Thin Section Epoxy Repairs if required using MasterTop P 650.
