Best way to clean Slick Sand?


New Member
Greetings fellow painters,

What I have done: Sprayed coats of SPI epoxy on raw fiberglass, Sprayed coats of Slick Sand, Block sanded with 220 grit, Blew pressured air

What I want to do:
Spray new coats of Slick Sand

Question: What's the best way to clean the Slick Sand, if cleaning is needed at all?

Note that I have SPI's 700 and 710 cleaners, and also the Pro51 Wax and Grease Remover below. Thanks for your input!

If you haven't contaminated it I would blow it, tack it and shoot it. Did you drip sweat on it or something? Or leave off tacking it, just dust off with a clean cloth and air.


Trying to be the best me, I can be
Just for peace of mind I'd use the SPI 700. Spray it on, wipe it off with a proper type prep wipe (never use anything but a prep wipe), no microfiber cloths or other "clean" cloths.

Idk, if its freshly sanded... it is porous, id be careful putting water based on it. Dry it thoroughly.

Because of the recent server crash, the tail end of this thread was lost in the ether. To summarize what I had stated earlier, I decided to get a new spray bottle. I sprayed the slick sand with SPI's water-based #700 and wiped it with painter paper sheets, a couple of times, taking off residual grey slick sand powder. I then waited for 24 hours and finally sprayed three new coats of Slick Sand. It's looking good so far.
Thanks again for all the help guys.
