Residential and Commercial Pressure Washing Specia
Was helping a friend seal some pavers. When we got there tonight there were white stains on the pavers from the caustic beads. It appears like the caustic bleached some of the pavers. Is this something that can be fixed? What should I do? Thanks for your help.
 
I would somewhat agree in the sense that if they were integral colored gray when made and the color is leached or bleached out they never gonna be like as good as new. Only option would be to replace or ask for mercy in letting you stain/mask them...
Still could be case of not knowing exactly what yer looking at. I advise posting pics up to clarify that your not just dealing with efflo or a previousely sealed situation. Previous seal getting water under it will whiten out the finish. Solution in such case can get complex. Waterbased seal may clear out once good and dry but don't count on it. More than likely the water will have wasted and changed the makeup AND adhesion of the finish/coating/seal. If it don't dry out then removal is in order. Solvent based going white can have similar issues but doesn't usually clear up unless flashing/remelting with xylene and/or recoating.

they were stained ofter cleaning
 
Hi. Mark
Sounds like they were sealed with moisture still trapped in the brick, I always leave them atleast 24 hours of minimum 45 degree weather and thats with full sun.

Ive had to remove some similar homeowner f-ups up here, and it's alot of really hot water and moving very slow and carefully with a turbo.

Not saying that's the right way, but the only way I found other than wait a year for it to wear.
 
Here's a tip to see if you have waited long enough before sealing.

Before sealing, throw a rubber mat down on the surface and wait a few minutes. Pick up the mat and look at the side that was facing down. If there's condensation on it, the surface insn't completely dry.
 
Last on this was that he thought there wasn't any previous seal left and it turned white after cleaning and not that it turned after resealing. I am left to think efflo with out seeing it up close. For all we know it could have a flattened or natural look solvent or waterbased seal still on there and that is what whitened/clouded out..fun times anyway ya slice it..
