I'm thinking about sealing my Oklahoma flagstone. I read that I need to pressure wash it first and do it first thing in the morning when its cool outside. I was going to use the 511 sealer from home depot unless someone has a better suggestion. I'll be converting to salt soon and want to do this first.
Also there is a small hairline crack in the mortar on my flagstone spillway from my hot tub. Can I just use sanded caulk to seal this? On the back of my pool I have a moss rock weeping wall. I guess I should seal this too. My only concern is the bottom level always sits in the water and I'd have to drain some water out in order to apply the sealer and then leave it drained for a day for it to dry. I'm worried this will cause a ring on the white plaster.
