    raising deck level around IG pool - building up bond beam?

    I'm going to echo what Brian and Jimmy have already said. You'd want to chip out existing bond beam to expose rebar to tie into the bonding grid (preferably in a few places), lots of rebar dowels epoxied into the existing bond beam, and a high strength concrete pour to raise it. And as Jimmy...

    Shell All 1 Pour or 2 Stages??

    As Brian said, no cold joint if done properly. Not sure how doing it multiple stages would "get rid of rebound", but it shouldn't have any negative impact. Cold joints in shotcrete (gunite) are in some ways a myth. Laboratory testing has shown that multiple layer shotcrete has no anisotropic...

    Confused by "gravel" types

    Because it has both AASHTO size #5 & size #7 rocks. Probably doesn't help explain it much, but trying to understand or explain the naming conventions for AASHTO aggregate sizing is an exercise in frustration.

    Start Watering New Gunite Right Away, or Wait?

    It likely means the top layer of the shotcrete is relatively porous, so water is both getting sucked into the interior faster when you water it, and evaporating from near the surface faster after you're done watering. Could also mean that ambient conditions are promoting fast evaporation...

    Start Watering New Gunite Right Away, or Wait?

    I wouldn't worry about it too much. The primary purpose of watering is to increase the strength of the final product, but even if you didn't water it at all it should be more than strong enough for the intended purpose (assuming proper mix and placement). You also live in a very humid climate...

    Skimmer Replacement

    You could, but you'll need to add a plasticizer to get it to flow into a space that small with the proper water to cement ratio. Even then I'd be worried about voids.

    Is this something I can do? Tile my whole pool that is.

    The mixer is the easy part. You also need a crew of several skilled plasterers because it all has to be applied nearly simultaneously or it will develop cracks where fresh plaster meets partially cured plaster. You're really better off hiring it out. Tiling is an option, but requires...

    DIY Pool Rehab

    Shortly after getting the pool up and running a small wet spot developed in the decking above the water line for the autofill pot. It's been attracting tons of bees, and a kid got stung during a pool party on Sat, so yesterday I finally got around to chipping out some concrete to investigate...

    fixing underside of pool deck

    The flexible sealant recommendation was in response to issue #2, the section of decking that's lifted due to earthquake/settling. You're not going to fix the issue with even the best adhesive/sealant, I was merely making a recommendation for something to help prevent water infiltration until...

    Skimmer Replacement

    Go back and read the article in post #12 of this thread. There's an expansion joint between the decking and the skimmer pour. You sort of have the right idea, but it'll be a lot easier to do in one pour making the separation/expansion joints vertical rather than horizontal as you're...

    fixing underside of pool deck

    Any of them. The 2nd one is specifically designed for use with concrete and the one I'd likely opt for, but all will work. The only difference between the other two is color.

    fixing underside of pool deck

    Issue 1 is a tough one. I think hydraulic cement would work well for this if you can get the cracks cleaned out well enough, and try to only apply in the crack rather than overlapping the paint at all, but that is a big if. It doesn't expand enough to cause issues unless a piece is barely...

    Yet another "how do I" thread (but at least I am a supporter now :))

    1) You should really try to do the pour in as few pours as possible Doesn't look like much volume, so depending on the volume of your mixer maybe you could get it with a single batch. 2) Why are you replacing all the water with bonding adhesive? That may not be a great idea in conjunction...

    Skimmer Replacement

    Not sure who you talked to at Custom Building Products, but they have two thinsets that are rated for submerged applications, both of which are carried by most Home Depot's. As mentioned in my PM a waterproofing agent on the bond beam beneath the tile is a good idea, and I like to use...

    Suggestions for repair of limestone coping

    Either one will work. Sanded will be more textured and won't fill in the really small holes and crevices. Non-sanded will be smoother and fill in every little hole. I'd probably use sanded to maintain a little more of the natural stone texture, but it's really personal preference. Looks to...
