Скачать или смотреть New Pool Surface Issues: What is Normal and What is a Defect?

So what is a normal discoloration and what is a defect in a plaster job? That is a tough one and what may look like a defect could be perfectly normal. Almost every builder makes a customer sign a form stating that color variations are normal and we call that Mottling in the industry.

I have seen several problems caused by the improper filling of a plaster pool. Unlike Pebble Tec, Fiberglass, and Vinyl pools, plaster pools pose some significant issues even when you are just filling a newly plastered pool. It is basically like wet cement in the first few days. One thing you should never do is turn off the water before it is above the tile line. If you do, there is a big chance that you will have a ring around the entire pool, right where the water was turned off at. This ring of discolored plaster will be permanent. You also do not want to use the autofill to fill the pool. That line will leave a streak down the side of the plaster at the autofill outlet into the pool. Last, you want to make sure the hose you fill the pool with is wrapped in a towel and left in the deep end of the pool. Any failure of these points will leave some type of discoloration in the plaster.

Brushing the pool is also a critical step in a correct plaster start-up. But you only want to use a soft bristle brush, nylon, or poly bristles. These are the brush type of choice. Do not use any pool brush with Stainless Steel or wire bristles or this will leave permanent marks on the pool surface. You also do not want to put any type of vacuum in the pool for the first 3-4 weeks. If you vacuum the pool with your manual vacuum with wheels, chances are you will leave wheel marks in the plaster that may not come off until the pool is drained, and acid washed. Even using a leaf rake on the bottom can cause some marks if you are not careful. The only thing I suggest for the first week is brushing the pool with a nylon brush and doing nothing else.

I have seen some new plaster pools with dog footprints, kid’s hands and feet marks, and object marks on the surface and walls. While the plaster is curing you should not enter the pool and you should try your best to keep pets and kids out of the water. I wouldn’t get in the pool for the first 2-3 weeks and if you use the pool the first week prepare to leave some marks on the pool plaster. The best thing you can do is to keep the pool off-limits for the first 2-3 weeks. No pool toys in the pool and no swimming.

With a proper start-up and plenty of brushing, the plaster can feel very smooth but still be rough in many areas. I suggest if you have young children, maybe purchase some swim shoes for the first 6 months. The kids will likely be using the pool for hours on end and over time their feet and hands will get small abrasions to form the new plaster, causing bleeding. This is perfectly normal and almost all new plaster will do this to your feet and hands. After the plaster fully cures this won’t be an issue, but that could take up to 6 months.

Just keep in mind that it takes a while for a new plaster pool to fully cure. Anything you do to it in the first two weeks can cause permanent marks and damage to the surface.

In recent years I have also seen known defects in PebbleTec pools. A rust stain will appear, sometimes dozens of them the size of a pencil eraser or a penny. These are caused by bad pebbles that have metal in them. The builder will warranty this and he will chip out the bad pebbles. The rust stains should go away at this point.

Another issue that is common with PebbleTec is calcium build up causing a white hazy appearance to the pebbles. This can be cured with a drain and bead blasting (glass beading) and is not a defect. But the process to remove the calcium is expensive. It is just a natural occurrence since PebbleTec is rock and calcium buildup is inevitable.
