replaster pool over existing plaster

If you want to resurface a concrete pool, your most economical choice is plaster. Certain products, such as Sider-Proof, actually make resurfacing in plaster easy enough for a do-it-yourselfer to tackle.

All in all, the average cost of resurfacing a pool in the U.S. is $7,000 per 1,000 square feet. Depending on where you live and what kind of pool you have, you can expect to pay anywhere between $1,500 and $100,000 for a quality resurfacing job.

The average cost per square foot is between $1-5. While there are some DIY options, most pool owners will hire a professional to replace the liners.
