Why Sealed Pavers Turn Cloudy or White (and What to Do)
A milky white haze on a recently sealed patio is frustrating. It's often called sealer blush, and it's usually moisture caught in the coating.
Common causes
Sealing a surface that wasn't fully dry, rain or dew before the sealer cured, or a coat applied too heavily.
Not the same as efflorescence
Efflorescence is a white mineral deposit coming out of the paver itself. Blush sits in the sealer layer. They're treated differently.
How it's fixed
Depending on the product, blush may be reactivated with a solvent or the sealer may need removing and reapplying.
What to avoid
- Sealing over it again
- Scrubbing with acid, which won't fix sealer blush
When to call a professional
Send close photos of the haze and the product name if you know it, and we'll tell you what's involved. See our paver sealing service.
What customers say
"I used First Class Pressure Cleaning to seal my aggregate driveway and they did a fantastic job. It was in rough shape as we had never sealed it before. Lots of salt damage as well from trying to de-ice the last winter storm. It looks so much better now. They even came back the next day for touch-ups on some areas where the winter salts had worn through to the concrete. Very happy with this company and the work they’ve done!"

"Great job done by Wally & crew for 1st Class Power wash. Front & Back porches along with large patio and lots of stairs. Furniture and planters moved and replaced. Sealant added to protect patio. Will use again!"

"Highly recommend! Andrew and his team were great at communicating and worked around rainy weather days to clean and seal our stamped concrete around the pool to ensure the product would successfully seal it. They were on time, friendly, and their communication throughout the process was amazing!"
