View Full Version : New patio install. Have a question about joint sand
08-03-2009, 07:56 PM
We just finished up with a small patio 10x10. We used the Holland pavers for this job. After we swept in the joint sand( Paver Set Polymeric Sand by sakrete) it left a white milky film to the pavers. We have used this product for all our jobs and this is the first time we have seen this. Its only in the spots where the sand was dumped on to the pavers. After calling sakrete up they told us to use white vinegar and water. We did this and nothing. What can we use to take the milky film off the pavers? :confused:

Darren, most likely that film is joint sand that was not completely removed or was pushed into the surface of the pavers when dumped. Many companies have chemicals to attempt to remove the poly sand, but it wearing away will be about the best. Have know guys to take a wire brush to the pavers, but some skill is involved to prevent gouging or streaking. You also have to be using a paver that is hard enough to be brushed.
If this problem had occurred with Techni-Seal, SRW or one of the other paver related producers, I'm sure you would be able to get a rep right out there for assistance. Not sure if your going to get that good of a response from Sakrete. They are marketing towards the homeowners, rather than the professionals.

I would use Techniseal Hardscape cleaner. We use it 5 to 1 ratio. we use it on
all jobs, which we used polymeric sand on. Leaves it nice and clean.
Best of luck.

Thanks for the help guys. We cleaned (swept) the patio twice before we lightly misted it with water. We have used white vinegar water solution and then tryed tsp cleaner.. Was going to try a efflorescence cleaner and see if that helps.. Where could I get techniseal hardscape cleaner??
Thanks again guys

Whoever sells the other Techniseal products can get it.

Just sweeping will leave a fine layer of dust, that when activated by water leaves a haze or slight, rough texture to the pavers. Best success is when a blower is used, with caution, to clean the joints to the chamfer and remove and excess or dust from the surrounding pavers.
Try here for a local Tecniseal dealer or contact the rep for some guidance or on location assistance. http://techniseal.com/locator.php?region_Id=1&langue_Id=1
I am meeting with the local Techniseal rep tomorrow on a perplexing job, so that I can gain the "manufacturers" recommendations.
