When paver sealing makes sense
Paver sealing isn't required for the pavers to function — properly installed pavers with polymeric joint sand last 25-50 years with no sealer at all. Sealing is an aesthetic and protective choice that makes sense in three situations: when colors have faded or weathered, when joint sand has degraded and needs reactivation, or when stain protection matters (driveways with frequent oil exposure, pool decks with sunscreen/chlorine exposure).
Sealing schedule
Year 0 (after installation): no sealing — let pavers cure and weather for 60-90 days first. Year 1-5: optional first sealing if color enhancement is desired. Year 5-7: typical first sealing on installations that didn't get an early seal. Year 7-12: second sealing if needed. Most paver installations need 2-3 sealings over their 30-50 year life.
Sealer types we use
Penetrating sealers: soak into the paver to provide stain resistance without changing appearance. Best for driveways and high-traffic areas. Film-forming sealers: create a protective layer on top, enhance color (wet look). Best for patios and decorative areas where appearance matters. Joint-stabilizing sealers: combine sealing with polymeric sand activation in one application.
What sealing won't fix
Settled pavers: sealing doesn't lift sunken sections. Broken pavers: cracked or chipped pavers need replacement, not sealer. Missing joint sand: requires fresh polymeric sand application before sealing. Severe staining: oil that's penetrated deep into the paver needs poultice treatment before sealing.
