We got off to a late start this year but my grandfathers pool has finally been opened.

Anyway, the patio surrounding the pool consisting of 1 foot cement tiles hasnt been cleaned by more than a hose for nearly 40 years. Some of these stones, which probably used to be whitish, are black, and the remainder are thickly covered in moss. My question is this, if we were to rent a powerwasher(or more likely borrow a 9HP unit from my contractor), what amount of power would be neccesary? Also, what type of cleaning solution is needed, if any, to get these cement squares back to there original color, and to try to keep the moss away? What rates do the high end units rent at? Is their anything else I should know(other than don't touch the stream)?

Thanks,

Mike

Problem is, I need it out instantly, I cant wait for some chemicals to work their magic. I was thinking of just dousing it in gasoline and trying to burn it, but its a little close to the fence.

Wow, I botched that.  I meant stamping tool, the ones meant for packing down dirt. This root was about 4 inches by 6 inches.

Mike

Not this one. We spent 2 hours today with a drill and a 10 pound metal stamoung tool to cut the smallest root.

My other friend did say he would let me borrow his chain saw.

Mike

Thanks. An axe could be used for the roots, but not for the stump. I assume whoever I borrow the chainsaw from will have an axe, so I will borrow one of those too. I was kidding about the ANFO, though it is tempting.

The stump needs to go. We will be putting a track down for a cart(it is going to be a ride through), and that stump is right in the way.
