Stamped Concrete or Paver Sealer Turned White

Thank you for visiting Concrete Sealer Review throughout 2022 and beyond for concrete and brick paver sealer tips and advice. In this article, we explain what causes concrete or brick paver sealer to turn white sometimes, and what you can do to fix it. If you have any suggestions for the best way to fix concrete or brick paver sealer that turned white, or if you have any questions, feel free to leave us a comment below.


Paver Sealer Turned White

Paver Sealer Turned White

Why has my Brick Paver or Stamped Concrete Sealer Turned White?

This is a very common question and a fairly common occurrence. Typically, this happens to filming acrylic-based sealers that leave a shine on the surface. These sealers are typically applied to brick pavers and stamped concrete surfaces to enhance the overall appearance.

There is no one specific reason that your old sealer has blushed by turning white or cloudy, so there is no one remedy to fix it. In this article, we will go over the main reasons that your sealer has failed so you will be able to fix this problem permanently.

Cheap Acrylic Sealer

In general, just stay away from the paint stores or Big Box stores brands. These “wet look” sealers have a high failure rate due to the inferior acrylics used.

Solution: To fix you will need to remove the sealer with a concrete or paver sealer stripper.

Trapped Water/Moisture and Over Applied Sealer

Trapped moisture under the sealer is the most common reason that the sealer has turned white. This happens to sealers that are not breathable or over-applied. The sun will raise the moisture out of the concrete or bricks but the water cannot escape as it is trapped under the sealer.

Solution: Applying a solvent such as Xylene or Lacquer Thinner will emulsify the current sealer, removing the trapped moisture and restoring the shine. Not a guaranteed fix but is worth the attempt.

Solution 2: If the solvent does not work, you will need to use a sealer stripper to remove and start over.

Efflorescence Salts Trapped under Sealer

Efflorescence is a soluble salt that raises to the surface of the concrete after it is installed. This may never form or may take up to a year to show. Make sure that all efflorescence is removed prior to sealing the surface.

Solution: Strip off the sealer first, then use an efflorescence cleaner to remove the white residue.

Polymeric Sand Issue (New as of the last few years)

We have seen more and more issues with polymeric sand installs. Not so much an issue with the sand, but with poor installation. Polymeric sands are installed by sweeping the sand into the joints, then blowing off the excess from the top of the surface. The sand is then misted with water to activate the polymer bond. The problem arises when the sand is not completely removed from the top of the surface prior to misting with water. The polymeric sand in many cases contains “cementitious” properties. This, when activated by water, may leave a thin layer on top called a “poly haze”.

Solution: Strip off any sealer, then use a mild acid or white vinegar to remove the poly haze.
Please ask any questions you may have on removing the white haze from your brick pavers in the comment area below.

I only seem to get the white in the area between the bricks to look like grout. The cement is dyed and I tried Tolulene on some cracks and it took the color out. Can I use a stripper that won’t take out the color?

Best I could, floor is approx. 24’X30′ and the white is very sporadic.

These porcelain tiles were sealed but now have white film on them. Is this moisture caught under the sealer or effervescent? How can we fix it? We are in uk

Concrete contractor completed a new tan decorative walkway back in April. There are white marks up by the stoop. They have been there since the beginning. They applied a water based cure and sealer. Is there anything I can do?

I had a stamped patio poured last year. The guy also sealed it. It looked great at first and within two days it started showing white patches. I contacted the guy who did it and he said to clean it with soap and water. I have did this several times last year and this year and have got no results. Any ideas or suggestions on what to do?

In the process of resealing my patios. I had a contractor seal them last fall however white spots started to emerge after winter. I’ve since pressure washed the patios in hopes to just reseal. However I wanted to confirm if I need to strip the patios prior to sealing due to the white spots found in the pictures below. Please advise, and thank you for your time! This site is great.

Thank you for the quick response! I just want to confirm, even with me pressure washing the patio(s) I can still apply the xylene solvent? A few pavers have what looks like bare/raw spots.

Our paver patio was sealed two days ago. This morning we noticed that the edge of the patio has turned a hazy white, and there are also some water spots from our irrigation system (sprinklers were not run until a full 36 hours of dry time had passed-weather was warm, sunny and windy). Poly metric sand was used in the joints. Two questions: Can the hazy whiteness be easily removed from the affected pavers, or will the whole patio need to be re-sealed? Also, when the entire patio gets rained on (or sprayed with a hose), will the whole thing… Read more »

I have a stamped driveway and have a well which water leaves a white film where the sprinklers spray on the drive way. Is there a sealer that will keep the water from causing the white film.?

We poured concrete in winter and then sealed. We have white spots small and big under the sealer. What do I need to do to get back to original concrete finish? Also once sealer(clear) went out it significantly darkened the concrete. I’m guessing due to excess moisture? It has been poured for 5 months. Please help!!

SpecChem was the sealer the concrete guy used. It has efflorescence and white dots in the concrete. I just can’t get it out with sealer on. So not sure if we should strip sealer and clean with efflorescence cleaner and reseal or if it’s just a lost cause or something else we can put on concrete to keep a concrete floor.

Thank you…. Is there some proper prep work I should do prior to application? Wash it? Let it dry? For how long? I just read something about it needed to be very dry and no rain for like 48 hours for good application?!? Also, do you recommend spraying or rolling it on?

Hi, I have a colored/stamped concrete sidewalk, I sealed it a few years ago and it looked great, last summer it was starting to look like it needed it again, so I resealed, used same sealer I had some left over from first time. It was a very hot day when I did it… Looked good for about a month and noticed it getting white spots. Now I want to fix this problem this summer….so about 8 months later. How do I go about this? Try spraying Zylene on and try resealing? Just Zylene to see if it helps? Or… Read more »

Had my existing stamped patio re-sealed when I got more concrete pored about 4 months ago. They did not strip the original sealer before applying new. It looks like it is now turning white. Do I need to strip and re-seal?

I had a sealer applied and it turned white soon after. Applying Xylene makes my patio look new again but it only lasts a couple months and the white comes back. I have applied Xylene three times over the summer using a low nap paint roller and it’s still is coming back. Thoughts?

I have a coloured stamped back patio. I tried to seal it myself with BEHR low luster seal which is water based and it dried cloudy white so I tried stripping it with BEHR masonry and concrete paint thinner. After stripping it looks even more white. I was scared to leave it on too long thinking the colour may go with it? So it was only maybe 5-10 minutes of sitting before washing off with steel brush and hose. When i wet it, the white areas go away but the colour pigment definitely looks different. Should I try stripping again… Read more »

I didn’t have enough square footage for a local person to refinish my stamped concrete, so I decided to do it myself. I pressure washed the front porch and I used some acetone to remove some light water spots. There were some stubborn water spots that I used a “15-minute stripper” from my shed. Well, now I have two sections with a white hazy look. Is this trapped moister? Is this stripper residue? What would you recommend? Xylene? Or should I get a sealer stripper? Or is there something else I need to do?

Had a patio poured 5 days ago with integral color then stamped with a darker release color. They stated they would not seal for a couple weeks. Some areas that have seen a lot of water have spots. It has also rained for 2-3 days. Any idea what the spots are and if there is anything I should have them do prior to sealing.

We needed to apply Xylene to release trapped moisture on a newly stamped driveway project. Basically the 1200 sq ft of driveway needed to be sprayed down with the xylene. Is a new application of sealer needed ?

My installer power washed concrete paver patio and sealed same day. A few weeks later, white spots like in this picture started to appear. They claim this is normal for concrete and will fade over time. Do you agree? Thanks in advance.

What causes the sealer to only get white blotches when it is wet (rain) BUT, all the white blotches go away as soon as the patio dries.? Seems like if it is trapped moisture, where does it go when the deck is dry? Dan

I put SW HC water based deck stain on stamped concrete, let dry 24 hrs. Then put 1coat
water based sealer, let dry 48 hrs, then second coat same sealer with nonskid additive mixed in. Deck dry for two days, then rain. Next morning, white haze splotched all over area that got wet. Here’s the kicker…when the sun drys the deck, all splotches go away?? What’s going on?! Dan from Pompano Beach

But why does the white haze go away entirely when the patio dries? Shouldn’t it still show when the patio is dry, if it’s moisture trapped? How do I take it off?

Hi, this question isn’t about white hazing but rather over spray lines. We applied our sealant on our 30 day old broom finish concrete and we have marks/overlap lines. If I spray Xylene, then roll out the sealer will it blend out the over applied sealer? Thus making the over spray lines less visible?

Hello! I applied Cure and Seal concrete sealer on my garage floor. It turned white and hazy. Is this an issue that has to be fixed or can I just let it be? I don’t care for the looks just want to make sure it is functional. Appreciate your advice on this!

Hi, I had a new driveway put in last week, and they sealed it with Sika sealant. It looked great. That night it rained and by the morning it looked horrible, with big white marks all over, some blocks were 100% covered, others not…very random. See photos. Is this bloom due to rain moisture trapped under sealant or efflorescence. Best removal method please?

If I have some areas with white and apply the sealer over this is the white going to show through?
The stamped concrete has been power washed. I sealed it a couple times myself using an inexpensive sealer Homax and it sounds like the problem was from my application.
I am hiring someone to reseal it and want to know if using this sealer will eliminate the white. I have not sealed it in over 5 years and don’t really think there is any sealer left on it.

We have colored concrete that was stamped with a slate pattern. They used a liquid release instead of powder. Then sealed a day or 2 after the pour…. it did not rain before the sealer dried but it was cold.it looked beautiful. Within a short period of time we noticed some whiteish spots in one area. Now a month and a half or so later we are seeing more whiteish areas all over. Is this normal color from the concrete or is something not right?
