replaster or do aqua bright

i have a 1960s kidney shaped pool with stains in its marble dust plaster, i wanted to know if anyone has done the aqua bright instead of replastering , is it better ,more cost efficient , etc

thanks for any info

Resurfacing a pool depends FIRST on contractor skill and dedication, and only SECOND on material. So, you're asking the wrong question. The question you want to ask is, "What pool surface, that can be skillfully applied by a finish contractor from MY area, would be best?".

You do NOT want to be a local contractor's test case for "Aqua Bright", no matter how great a surface it is.

Bottom line: this is usually not a question we can help much with, especially for forum members who do not identify the area of the country they are in.

Good luck!
