If you a swimming pool in your homes outdoor area, you probably want to keep it in good shape. You may even pay a service to regularly clean it and change the chemicals.
After about 10 years, an in-ground swimming pool with a plaster finish may start to show signs that its time to have the plaster redone. Warning signs include mineral stains, worn spots where the concrete or gunite shows through, and roughness on 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 thin.) Keeping your pools plaster in good shape is also important because the plaster increases the pools structural integrity.
The typical cost to have a pool replastered is between $4 and $7 per square foot. 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, thats total of 1,088 square feet. If the cost is $5 per square foot, replastering would cost $5,440. If you are unsure if replastering is called for, you should have a pool repair company like Pool Care in Brentwood, California, or Pools in Cypress. Texas, come and inspect it for you.
Replastering a pool is best done by an experienced professional with appropriate expertise and equipment. The typical process is as follows:
Clean and drain the pool, remove debris, and scrape pool walls with a wire brush or chisel to remove peeling plaster.
Acid-wash the pool.
Sand the pool surface to create a smooth surface that helps the new plaster adhere.
Apply the new plaster in small sections, allowing each to dry completely.
Refill the pool with fresh water and adjust the chemicals.
If the plaster on your pools surface is in really bad shape, your cost will go up to cover any additional repairs that may be required. Other repairs, like retiling, will add to the cost as well. If your pool has stains from minerals in the water like copper and iron, your pool pro may recommend that you deal with the problem if its source can be identified.
Fiberglass and vinyl-lined pools can be resurfaced for about the same cost as replastering a concrete pool: $2,500-$4,000.
