Thanks for posting the link to that article. When it comes to cementitious products, I drive my subs crazy. I cover all slabs and keep them wet for at least two weeks. Stucco gets water several times a day. They often do not understand that if the material drys out the curing/crystallization stops and will not resume when it gets wet again. I'll be spraying my fresh plaster often until I can cover the pool with plastic overnight. No doubt the plasterers will think I'm crazy.
I was using plaster as a general term. I'm doing a pebble finish with an acid wash the next day to expose the aggregate.I think @onBalance csn give you better advice on this. I don’t think you want to wet plaster or else it will stain. I believe with plaster you want to let it set for a minimum of 6 hours after final trowel abs then fill immediately. I’m not sure if that same process applies to pebble finishes as well because they need to an acid etch to expose the aggregate. Again, Kim knows more than anyone about proper plaster startups.
I'm thinking about completely covering the pool with a large plastic sheet as soon as the plaster is done and leaving it until the acid wash to expose the pebbles. Black plastic to keep the sun out and keep the heat at the plastic. It would probably only be covered for a day but it would prevent premature drying and keep the plaster cooler. Do you think it is worth doing?In 100 degree temps and low humidity conditions, I would tent a pool and use a portable evaporative cooler to keep temps lower and humidity higher while the pool is being plastered, acid washed, and left empty for any period of time.
I'm definitely insisting on first job of the morning. If they show up in the afternoon I'll send them away. Unfortunately the only plastic I can get locally is clear or black. My thinking on black was that while it would absorb more heat, that heat would be kept away from the plaster.Yes, that would be better than doing nothing. But insist on being the first pool in the morning, and I believe that a white or light colored plastic tarp would reflect the sun's heat better than black.
Did you impose any of the requirements on the crew? If so, did they follow the requirements? I will be getting plaster (mini pebble tec) soon probably sometime next month (fingers crossed). My PB has only been out twice, for the initial dig and to assess damages to my home from the subs hired. I've been managing the project myself. I will try to impose some of the requirements as well.Thanks for another great read. I'll try to impose as many of those requirements as possible. Since I have have been a little more testy with them about getting my job completed they may not go along with all. It has been ready for plaster for over 4 months now so I think I'm within reason for starting to push hard.
They started work a little after 6:00 and were done 4 hours later. 8 batches in total.Your plaster finish looks great. Covering the pool with the plastic tarp will go a long way in helping the plaster to properly hydrate.
I am curious, how many hours did it take from start to finish?
I had a few requirements. One was to do full thickness pebble and not an inferior scratch coat followed by the radiant fusion coats. Unfortunately we had some issues right off the bat. They showed up with white pebble to blend with the micro radiant fusion and I was not happy about it. They wanted to use 4 bags white pebble and 7 bags radiant fusion per batch. They wanted to do that to save money since the cost of materials has gone up so much. Nice try but I caught it. I decided to have them use only white pebble for the first 2 batches and thereafter use 2 bags white pebble and 9 bags radiant fusion. My pool has been ready to plaster for 5 months and I'm tired of waiting so I compromised instead of sending them home. We will see how the end result looks after the acid wash.Did you impose any of the requirements on the crew? If so, did they follow the requirements?
