Stay away from using concrete coating. Water gets under, it bubbles, and cracks. The so called«life time» warranty they claim is not backed by Superior Pools. I used them and within 2 years of the $ 1800 lifetime coating, it required pulling up concrete and re pouring to a tune of $ 4000. TJ turned his back on us and did absolutely nothing to resolve. Our pool is great, he did great installation and service on the pool. I thought we had a true lifetime pool company until the concrete he not only poured but coated years later failed terribly. Very disappointed.
