White Haze on Brick Pavers is a common problem that in most cases can be prevented by using a high quality Brick Paver Sealer or by prepping the Brick Pavers properly. The 4 things that can cause White Haze:

1. Moisture trapped under sealer while applying a sealer while pavers or ground is wet. This can be remedied by spraying on xylene or aromatic solvent. This will re-emulsify the coating, releasing the trapped moisture. It should go away almost immediately.

2. Build up of too many coats of sealer. Can be remedied with xylene but will probably come back eventually. This usually happens when a sealer has been over-applicated.

3. Application of our sealer over a "cheap" previous sealer. You will need to strip everything.

4. Efflorescence. White chalk that is prevalent on new pavers. Usually sealed in and cannot be fixed without stripping the entire job. Efflorescence usually goes away 6-12 months after the pavers have been installed. You can speed up the process by using a muriatic acid solution to remove the efflorescence. Be careful! To much muriatic acid can burn the pavers.

Xylene is not a stripper but an emulsifier that will help fix a lot of problems. If you need to remove you will need to us a methylene chloride based stripper .

avatar You need a paint stripper that contains "methylene chloride" A popular brand name is called "Dads Stripper". You roll on the stripper on a section that is roughly 10'x10'. Let sit for a few minutes then powerwash off. The old coating will peel back like a white "skin". Make sure to use protective clothing and a respirator. Protect all vegetation and the house. You may need to strip more then once if you have multiple coatings to remove.

Good luck as it is not very fun

HELP ME! - re:   | | 2008-11-22 00:08:54
Dear Deck guys I recently did a brick paver driveway and noticed when the job was done that some areas had more coats then others. Now some parts of my driveway are shinier then others what can I do? I noticed you said Build up of too many coats of sealer. Can be remedied with xylene.

Will the xylene depending on how much I put on dim the harsher areas of my driveways down to blend with the rest of the sealed coat? Or do you have any other suggestions for this.

What xylene product would you recommend?

avatar The xylene will not remove or dull the areas where there is buildup of sealer shine. The only way to fix this is to add another coat to make everything an even shine. You cannot remove shine without stripping everything and starting over.

How long has it been since it was sealed? It can take up to a month to cure and it may dull and look more even.
