3M quartz plaster

Doesn't look too good. Perhaps your local BBB could give you some advice on what to do.


3M quartz plaster

I found some pictures at http://cms.3m.com/cms/US/en/2-125/cFiliFP/view.jhtml and the plaster seems quite even, not much like yours. I don't know what I would do.

When you visit the other pools, try to ask the owners if they are happy with the plaster. If they are then the surface is probably close to what it should be. If the owners are unavailable when you visit, I would be suspicious that the company is trying to keep you away from possible negative feedback.

Good luck

Strange way of doing things. Letting a pool sit that long without water will lead to excessive check cracking. Didn't see the pictures but some check cracking is normal. Splotchiness and an ununiform dispersal of the colorquartz is normal. It's not a bathtub so don't expect perfection there's is just too many variables. The way we do colorquartz is last plasterer out drops the hose in and then we return for an in pool acid wash. That allows for the wet cure to begin when it should not a couple of days after the fact.

Anyone else have problems with a quartz plaster finish? My pool company has told me it's everything from the water well, brass valves, the heater...but certainly cannot be their product.
They acid washed it in December and problems are re appearing in March.

Quartz plaster problems

underthewire, it sounds as if you have a staining problem.

Stains are most often a result of metals such as copper that the pool company implied. Have the copper levels checked. If the problem is in your well water, then a metal-out product will prevent the stains. If the problem originates from the pool or its fixtures, you need to determine which fixture and why.

A low pH, total alkalinity, and/ or low hardness levels all lead to increased corrosion and breakdowns of metals, but also result in the etching and softening of the plaster surface, so you probably would have noticed something was wrong there.

Please give more details about the stains - size, color, progression.

We just had 3M done but solid white. It is not splotchy but it did stain while waiting to fill with water. Now that it is full the stains will not brush out. The pool company said the would take care of it. They did say to brush constantly and the more you brush the longer it would last. I have not noticed any cracks yet but the plaster dust in the water makes it hard to see.

I'm pleased to hear your pool is finally full after the extremely long wait and battle you have had.
