What Not to Do When Sealing Pavers
Sealing your paver patio is meant to protect and enhance it—but doing it incorrectly can do more harm than good. Whether you're applying a sealer for the first time or reapplying after a few years, knowing what not to do when sealing pavers is essential to avoid haze, peeling, or wasted product.
One of the biggest sealing paver patio mistakes is sealing too soon after installation. Applying sealant before the pavers fully cure and dry can trap moisture and efflorescence, leaving a cloudy, uneven finish that’s difficult to fix.
“A man who carries a cat by the tail learns something he can learn in no other way.”
— Mark Twain
When it comes to sealing, it’s best to learn from others’ mistakes—before making your own.
Common Sealing Issues and How to Prevent Them
Here are some of the most frequent sealing issues and how to avoid them:
-
Sealing before pavers are fully dry
Moisture beneath the surface leads to cloudiness and bonding failure. Wait 60–90 days after installation and allow at least 24–48 hours of dry weather before sealing. -
Skipping cleaning
Sealing over dirt, stains, or efflorescence locks imperfections in place. Always pressure wash and brush the surface, then let it dry completely. -
Applying too thick a coat
More isn’t better. Over-application causes bubbling and peeling. Apply in thin, even layers with a sprayer or roller. -
Using the wrong type of sealer
Not all sealers are compatible with all paver types. Choose the right formula—film-forming for gloss, penetrating for natural looks, and breathable for wet climates. -
Not compacting jointing sand beforehand
Without compaction, sand won’t settle properly, and sealing won’t lock it in. That leads to early erosion and weed growth.
Seal Smarter with the Right Tool
Before sealing, compact the surface and jointing sand one final time. The Tomahawk JXPC50H Plate Compactor is ideal for this task. With 1,420 lbs. of compaction force and a homeowner-friendly electric design, it helps prevent loose sand and ensures a smooth, tight finish for better sealer adhesion.
“If you don't have time to do it right, when will you have time to do it over?”
— John Wooden
Sealing is only as strong as the prep work that comes before it.
