Does concrete need to be sealed after curing?
Sealing concrete is important for long term durability. Film forming sealers generally impart a gloss to seal the surface and reduce staining of the underlying concrete. Penetrating sealers generally do not change the appearance of the concrete surface but provide better long term protection against the deteriorating effects of such elements as de-icing salts, acid rain, sea water and ocean spray. Sealing products are used after the initial curing compound has worn away. Typically 30-45 days.
