Roof Area Roof Slope how-to Calc. For most contractors, keeping fresh concrete clean and new-looking is a real problem. No one can afford to wait until it cures, yet construction traffic is likely to leave permanent stains from oil, grease, dirt, chalk, etc. Accumulated dirt, grime, grease, oils, and other soils will be kept at the surface for easy wash-off prior to application of a final sealant. It boasts the same resistance to chemicals as standard StoneSaver , but behaves differently.
High alkalinity interferes with the bonding chemistry of most finishing sealants.
It sets up with microscopic pores which will allow moisture to escape, but will prevent penetration by the inherently larger molecules of stain-causing materials. It will erode faster, and will not completely reject water. The concrete's curing will continue for some time, but at 30 days its chemistry is compatible with standard StoneSaver sealant. The two sealants are totally compatible with one another. The performance of standard StoneSaver is unaffected whether or not Qwik- Start is first applied.
