White Haze on Pavers

Written by Scott Paul

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 .

What is the proper way to use methylene to remove xylene / silicone based clear
coat from pavers on a driveway ? I need help !
DeckRestAdmin |Y-m-d H:i:s
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

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?
DeckRestAdmin |Y-m-d H:i:s
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.

it's always good - to read instructions before application of the stuff. it
causes the majority of problems.

as a saying goes - who buys cheap suit pays twice. a cedar fence or pave owner
should use something to furnish it corresponding by price.

I think that the product has a proper price to be applyed to really good brick
paves. Is there any sealer for woods with the same non-yellowing effect?

maybe the partial replacement would help?

Stripping of the previous sealer seems to be the cure for the white haze on the
brick pavers. This is the problem I am facing in connection with the brick
pavers in my home.

Do you hink this product will also help keep the moss down? I noticed the pavers
on one side of my residence tend to grow moss. It makes sense it is shaded and
on the rain side of the house, I scrap it off and have used a sealer yet the
moss returns, Is it because it is sealed improperly or is it the actual sealer
that makes a good host for the moss?
DeckRestAdmin |Y-m-d H:i:s
No this product will not help with moss. the sealer also does not promote moss
growth. Moss typically grows in wet ground and that is probably why it keeps
coming back.

It seems very common for all types of pavers to develop this white haze and one
is not aware of the cause due to efflorescence. If at all this happens, it would
be advised to leave the professional deck engineers to cure this.

They do not all get a white haze but a small percentage will.
