If you recently installed a concrete pool in your home or backyard, maintenence is important to you and you want to keep it looking great. Many pool owners pay a pool service to regularly clean it and properly adjust it and add chemicals. This is to provide assurance that your expensive investment is protected with expertise. Too often, fly by the night pool cleaners can cause more harm than you can imagine. They often offer the lowest prices to gain clients and they do not have expertise, training, or skills to properly deal with plaster finish pools. The end results can be expensive repairs.
After about 5-10, (or sooner if your pool water chemistry is off) years, an in-ground swimming pool with a plaster finish may start to show signs that it’s time to have the plaster redone. Warning signs include metalic stains, wear spots where the concrete or shotcrete shows through, and roughness of the surface that makes it uncomfortable to walk or sit on. (If it is unpleasant to run your hand along the side of the pool or to climb up the stairs, your plaster may be wearing out.) Keeping your pool’s plaster in great shape is also important because the plaster increases the pool’s structural value and integrity.
Pool plaster cost
The typical cost to have a pool replastered is between $30 and $50 per square foot in Wisconsin. Prices for plastering are far less in Florida due to the quantity of pools and much longer seasons. Therefore, it’s impossible to compare Florida and Texas to Wisconsin. Assuming an average pool size of 16 feet by 32 feet, 4 feet deep on the shallow end and 8 feet on the deep end, that’s total of 1,088 square feet. If the cost is $29 per square foot, replastering would cost $31,552. If you are not certain if replastering is called for, your pool may be a candidate for resurfacing, you should have a pool repair company like Pool Envy in Green Bay, Wisconsin, or Pool Envy in Texas, come and inspect it for you.

- Bicarbonate wash the swimming pool to close up the capilaries in the pool plaster and

Other repairs like replacing tiles will add to the cost as well.
