SP Interlock

SP Interlock – single component water-based coating containing a combination of non-acidic water-soluble agents, which penetrate through the open pores of aged concrete. SP Interlock sets up a chemical reaction (within the concrete) with the salts and limes present. It purges the impurities and unlike other sealants, SP Interlock works from the inside out. This is not a surface sealant. SP Interlock works to replace solids lost by age and weathering to strengthen concrete and works great on fixing salt damp. Learn More SPI >
