![]() Removing plaster/cement material is generally detrimental. Regardless of how those treatments are done, acid treatments (bath or wash) are generally detrimental to a plaster finish, whether it is typical white plaster, colored plaster, color quartz or pebble pools. After a few days of that acid wash treatment, they will neutralize the pool water with sodium bicarbonate or perhaps soda ash. Some plaster companies will fill quartz pools immediately after plastering and then do an acid "bath" (adding many gallons of acid to the pool water) once the pool is filled with water. Some plaster companies will acid "wash" both quartz and pebble pools before filling to remove the so-called cream layer and expose the quartz or pebble, and they may do that the day of plastering or the day after. My plaster looked like white day 1 almost but day after day it was like opening up a gift.įrom all I read quartz should be filled right after it’s done like other finishes. If u look at my plaster day 1 and after all the brushing it’s night and day. I didn’t see any of those in my quartz either bit after all my brushing they came through cause I was taking off the cream and dust. Regarding the change in color after the acid wash. It’s amazing the change in surface over that month from brushing. He said more of a better to be safe than sorry. I also followed up woth the owner of the plaster company and he said the same thing. I even commented to my builder and his guy who speaks Spanish talked woth the guys and they explained this. I have quartz and the plaster company barely used acid before we filled causexthey wanted me to brush off the cream so the surface would not get worn with a full acid wash. ![]() Bond: are you satisfied that whatever those stains were, were normal for a quartz finish, or were they the result of a faulty installation? And if the latter, is correcting it as they are doing a satisfactory solution, or a hack job to cover their mistakes? Again, I have no idea, but I'd like to. I'm glad that the spa and pool are looking better. Sorry, I'm asking more questions than I can answer, but those are the answers I'd want to know if this were my pool. And how is the acid neutralized once it's done? Did your guy neutralize the whole pool? Or just add acid, brush it around, and tank the entire pool's pH? If the latter, what are the long term effects of lowering the pH like that on new plaster (and other pool equipment)? How does one do a controlled acid wash with the pool full of water? I hadn't heard of that before. Do small areas at a time, and as quickly as possible. Not just rinse it into the deep end, unless the deep end is filled with a neutralizing solution. Apply that mixture appropriately to the affected areas, and when the acid has performed its "duty," neutralize it immediately. Prepare the acid mixture to the "strength" (pH) required for the job (but no stronger). Pre-prepare some sort of neutralizing capability. Huh? This is what I was taught constitutes a proper acid wash. One of the pic's implies they are somehow acid washing the sun deck while the pool is full. From the pics, it seems they emptied Bond's spa to acid wash it, or did you say they didn't use acid on the spa? What did they do?ĥ. Does that weaken the pebble and/or expose more of the pebbles than it should? Would that second wash impact its lifespan?Ĥ. Acid washing pebble a second time (assuming it was acid washed enough the first time) would reveal more pebble than is preferred. Acid washing new plaster would compromise its feel, it's smoothness and its lifespan to some degree.Ģ. Pebble is acid washed to remove enough plaster to reveal the right amount of pebble. IMissNimoy: your signature says "gray plaster." I was unaware that plaster would be acid washed as part of a normal installation. Just to remind, I feel I only have a slight handle on some of this, and have no experience with quartz.
