After 8 years, we have a few cracks and chips in the pebble tec of our spa. We were told by many pool professionals we should re-pebble the entire spa, as it will only last 8-10 years. But after reading the great info on this forum, it appears the pebble tec should last up to 20 years!! Note, the spa doesn't have any cracks (we did a dye test).
Thanks for any advice in advance. I was going to call the contractor tomorrow to set a date to re-pebble both the pool and spa (as was recommended to do it before it got worse), but I'm hoping just a patch and repair job will do the trick!
