View Full Version : Pressure Washing Cool Deck

I just got my first job pressure washing a Cool Deck Patio. Should I be concerned, as this type of surface is very thin. What would you guys use to clean this. It has stains from minerals from the sprinklers and just general dirt. My machine is 3750 PSI and 4 GPM.

I have to believe that someone out there knows the answer to this? Help, anybody?

The dirt can be easily remove with light water pressure. I'm not sure about the stain though. Kool deck is nothing more than a paint and a high psi washer, like yours, can remove the paint. If its too bad, try and sale your customer on a resurface job. It's very easy to do and you can buy everything you need at any local pool store. Good Luck

Thanks pool boy. So will chlorine mess it up?

Chlorine should be fine. Go by the kind you use for a swimming pool, rather than the kind for clothing. It has twice the active chlorine.

Pressure washing pool decks is fairly easy. You just need to clean them with lower pressure and use the appropriate cleaning solutions.
