Primera stone Wet edge finish issues, large circular spots

[raskle]

We recently completed a 14' x 34' gunite pool with the Primera Stone Wet edge Blue Ocean finish.
As soon as the pool was full we noticed a couple of 18 inch roundish blemishes in the plaster.

I would love to hear if anyone has seen this before or has advice. The installer said it might be scale and to wait 28 days for the plaster to cure.
Does this seem normal, if so what can be done about them?

I have Primera Stone as well, it was a replaster done in 2018. I don't remember having anything like this. Also, the picture you posted doesn't show that the plaster is smooth. It looks like indentations. They smoothed my whole pool with hydraulic sanders. Maybe it is just the resolution of the photo you posted. Can you feel a smooth finish? If so, is this section you pictured the same smoothness as an area that is good?

This area of the pool is a little lumpy and there is a slight divot around this blemish in the plaster

I would suggest having the PB or the plaster supervisor come out and look at this close up. Have them jump in the water and feel it. While all plaster is "handcrafted" so you can expect some inconsistencies, you should have them do a detailed review now and not wait 28 days.

Love this color, its a top contender for us. Would you say it trends navy blue or green? Can you post some more pictures? thanks!

Here are a couple of pictures of the plaster day and night. We really love the color and it is more blue than green.

what did your PB say about the spotting and indentations?
I have Primera Stone as well and no serious issues.

We fixed the white spots on our Primera stone plaster by burning them off with acid!
We likely spilled some water on those spots before the pool was full, and it left a ring
I cut a slot in a large sponge and zip-tied it to a piece of 3/4" PVC pipe.
Then wearing goggles and gloves I poured acid into the pipe with a funnel while the sponge end was submerged and over the spot.
Acid is heavier than water, so it sinks into the sponge.
I did not have to scrub too hard, the acid did most of the work.

Hope this helps someone else in the future.

Thanks...

Last question..is it slippery to walk on when you are in the pool? On the sun deck? The finish seems very smooth.

Hi Metal, my finish has a slight texture, feels like stone, and is not slippery at all. I imagine if there were some algae growth it could get slippery.

Hi Raskie - My Primera Stone finish, Sapphire Treasure, was installed six days ago and I have a large light spot in the deep end that is getting bigger and looks a lot like your ring except it is light all through the spot. I was actually thinking that the start up service had put acid in that area but not sure what has caused it. Did your contractor have any ideas what caused your issue?
