After several delays, it sounds like we'll finally be getting plaster this weekend!
Going with a custom color mini-pebble, similar to what I've seen described here as reverse Tahoe. Plaster guy likes the bicarb start-up idea and will allow me to handle it all without any impact to the warranty. He's actually a fan of the bicarb start-up for regular plaster, but hasn't seen it done on pebble before. He echoed my concerns about how smooth the old part of the baja shelf was (old plaster was barely bonded), and we've decided to do an acid etching, followed by scarifying the surface with an angle grinder, and then a good bod coat. His prep guy is coming out tomorrow to pressure wash and apply the bond coat, so I need to get the acid etching and scarification done tonight.
Have slowly been working away in the mean time, but don't really have any good pictures. Grouted the accent tile on the water feature wall, flushed all the plumbing lines just in case there was any dirt/debris in them, another pressure test with all the plumbing at the pad in place, plumbed the sheer descent, lots of touch up grinding on the concrete decking, installed the pool light, and got the filter set up (fresh o-rings, new glycerin filled gauge, filled with fresh sand). Have also purchased most of the supplies needed for the electrical work, but haven't had time to install the sub-panel or pull wire yet.
I'll be sure to post pictures of the progress this week. Kids are getting excited about being able to swim again.
