Problem: Article: Before you can begin refinishing your pool, you’ll need to be sure that you can afford it. The average resurfacing project costs around $6 per square foot. Add up the total square footage of your pool and multiply it by 6 to get a ballpark estimate of how much you can expect to spend.  Certain longer-lasting surfacing materials like fiberglass or tile may add considerably to the overall cost of your project.  This estimate only covers the costs of basic materials, and may not account for extensive repair work or additional equipment that may be necessary to see the project through. Start by removing all patio furniture, electronics and other accessories from the pool area and storing them in a separate location. Stripping a swimming pool tends to spread lots of dust and debris. If you’re not careful, you could ruin more delicate items and leave yourself with a big mess to clean up. Tape a few tarps or weather-resistant drop cloths down around the outer perimeter of the pool. Be sure to also throw one over any nearby furniture or appliances you can’t find storage space for. While the pool is still full, check to make sure the jets, filters, skimmers and lights are all working the way they’re supposed to. If there’s a problem with any of the pool’s equipment, you’ll be able to address it before the actual resurfacing gets underway.  Take a close look at each of these areas and perform a few quick tests, like turning the underwater lights off and on and running your hand over the jets to feel whether they’re circulating water correctly. Keep an eye out for debris and other large obstructions that may be clogging the skimmers.
Summary: Estimate your budget for the project. Clear the surrounding area. Protect the area around the pool. Confirm that the pool’s other features are functional.
