How Often Should Pavers Be Resealed?
By Athanasios Vamparis, NanoXperts Certified Surface Protection Specialist · Published
Rather than a fixed interval, it is more useful to know what shortens or extends the life of the protection on your specific installation.
What shortens the interval
Some installations need attention noticeably sooner than others:
- Driveways with vehicle traffic and turning tires
- Areas exposed to deicing salt and plowing
- Shaded, poorly draining patios that stay damp
- South-facing surfaces with heavy all-day UV
- Pool surrounds and grill areas with frequent spills
The water test
As with concrete, pour water on a clean, dry paver. Beading means the protection is still doing its job. Rapid absorption and darkening means the paver is drinking again.
Test in two or three different zones — a walkway edge behaves differently from the middle of a patio.
Joint sand and weeds
Loss of joint sand, weed growth and ants in the joints are separate issues from the protection itself, but they affect the overall result and should be addressed as part of the work rather than sealed over.
Do not wait for visible damage
Re-treating a surface that is still in decent condition is straightforward. Recovering a surface that has been absorbing stains for several seasons involves considerably more preparation.
