What types of sealers are there?
Typically, there are two types of carriers for sealers: water based or solvent based. However, there are many different types of sealers. Some are penetrating and some are surface sealers. Please contact us for the appropriate type for your specific project.
When is the best time to seal?
Concrete should not be sealed before full cure (28 days) and stone should be sealed as soon as possible in high-traffic areas. Patios and walkways sometimes do not require sealing.
What does a sealer do?
Sealers by name are a little deceiving as sealers do not block everything out. What they are intended for is to buy you time to clean up stains before they penetrate through the sealant.
How do I remove stains before sealing?
There are various cleaners for various stains and the selection is based on substrates. Please contact us before applying certain cleaners as they can have irreversible reactions with certain stones.
