MasterSeal 501/502 - Surface applied capillary waterproofing system for concrete and block work
How does MasterSeal 501/502 work?
The MasterSeal 501/502 waterproofing system ensures the total and permanent solution to water leakage, ingress, or seepage in concrete structures or any cementitious substrate. The formation and development of insoluble crystals into water bearing capillaries and interstices effectively blocks the further passage of water and ensures permanent water tightness for the life of the structure.
MasterSeal 501 Supplied as a powder and mixed to a slurry consistency with water. MasterSeal 501 is applied directly to concrete, blockwork or cement renders in areas where general waterproofing is required. In powder form, the product may be used as a dry shake on horizontal construction joints. MasterSeal 501 has been tested according to BS 6920 conformity test for use in water up to 50°C.
MasterSeal 502 Mixed to a mortar consistency with water, MasterSeal 502 is used as a screed on surfaces subject to foot traffic, as a render, for remedial patch repairs, to form fillets, and in conjunction with MasterSeal 501 on substrates including brickwork and badly leached concrete.
