Becoming a Paver Whisperer is a term we coined regarding letting the hardscape surface tell the applicator what type of sealer and how much of it should be applied.  Not all concrete pavers are designed the same and they have had different histories.  Some pavers may only need one coat of paver sealer, and others may need three coats.  Pavers that have been previously sealed typically don’t require two coats of sealer as quality sealers leave their chemical base in the pores of the paver, even if a film-forming topcoat has worn away.  Clay pavers should not be sealed with paver sealers designed for concrete; instead, they should be treated like natural stone for sealing purposes.
