Signs You Need Interlock Sealing

Water No Longer Beads – Water absorption indicates sealer has worn and pavers are unprotected from moisture damage
Colour Appears Faded – UV exposure has degraded the surface, sealing will restore and protect the original colour
Stains Penetrating Easily – Without sealer barrier, oil, grease and organic stains absorb into paver surface
White Haze or Peeling – Film-forming sealer is failing and needs to be stripped and reapplied
3+ Years Since Application – Most sealers need renewal every 2-3 years to maintain protection

Benefits of Sealing Interlock Pavers

Sealing provides multiple advantages:

Protection

  • Blocks oil, grease, and food stains from penetrating
  • Reduces water absorption and freeze-thaw damage
  • Shields against UV fading and colour loss
  • Prevents salt damage from winter de-icing
  • Inhibits moss, algae, and weed growth

Appearance

  • Enhances natural paver colours
  • Provides wet-look or matte finish options
  • Creates uniform appearance across surface
  • Hides minor surface imperfections
  • Restores faded pavers to like-new look

Maintenance

  • Makes cleaning easier - dirt does not penetrate
  • Spills wipe up instead of staining
  • Reduces frequency of deep cleaning needed
  • Stabilizes joint sand against washout
  • Extends time between re-sanding

Value

  • Extends paver lifespan significantly
  • Maintains property appearance
  • Protects your hardscape investment
  • Lower long-term maintenance costs

When Interlock Should Be Sealed

Timing matters for best results:

New Installations

  • Wait minimum 60-90 days after installation
  • Allow efflorescence to naturally release
  • Ensure pavers are fully cured
  • Clean before sealing

Existing Interlock

  • After professional cleaning
  • When current sealer has worn
  • Before staining becomes permanent
  • When colour enhancement is desired

Ideal Conditions

  • Dry pavers (no rain 24-48 hours prior)
  • Temperature 10C - 30C
  • Low humidity
  • No rain expected for 24 hours after
  • Late spring through early fall in Ottawa

Not Recommended When

  • Pavers are wet or damp
  • Rain is forecast
  • Temperature below 10C
