Faux Rock and Pebble Tec Renovation

I have an almost 20 year old pool with a lot of Faux Rock Surface that is in need of some refinishing and repairs. Hoping to get some insight and support from an others that have dealt with this as it seems advise from different guys that do the work is all over the place. We live in the high desert and the hold/cold cycles have been hard on it. Any insight anyone has on the repair/repaint/replaster would be appreciated. My biggest question is on the faux rock refinishing with I left at the end.

Start with the pebble tec:
The spa is cracking and delaminating on the seats and step. It is going to need to be replaced in the spa at minimum. I found after removing some pieces that it was originally a blue color!? We have been in the house 7 years and it was never a blue color since we have been here. However the pool area is still in decent shape with no cracks(faded the same), however you can tell that some of the mortar has been worn away. I can pick some of the pebbles of fairly easily.

How much of the stone surface is originally exposed with pebble tec?

I have gotten some quotes from guys that work as subs to local pool contractors, around 10k for the pool and spa to be demod out and have StoneScape Mini Pebble installed. The Spa alone is 3-4k so I will likely bite the bullet and spend the $ and do both the pool and spa so they match. The Pool companies these guys are subs for wants 16k for the same install. For 6k less I will probably go with a sub directly.

Now for the more confusing part and area that is hard to find more information on. The Faux Rock:

I have some obvious areas that are going to need repairs. Lots of hairline cracks. I have gotten some guys that say 50% of it needs to be torn out and replaced for up to 60k in cost. Most say to use some sort of bond kote product over the big cracks and paint or stain it accepting that the hairline cracks will be there and show back up forever and that is the nature of the beast.

The bridge across the skimmer is going to need to be completely torn out and replaced. I epoxied it together years ago.

So after I determine the best method of repairs. One of the biggest questions that comes up is what is the best methods for re coloring the faux rocks?
Some guys want to use concrete stains, some want to use paint products. Usually exterior latex paint watered down. Some say put a Sealer on after to help keep water from getting into the hairline cracks, some say it is a bad idea to use sealer because it will need to be sand blasted off if you ever want to repaint it again. There isn't a lot of information I can find on this online. I understand the idea of not using sealer because the problems with repaint. However I also get the idea of water proofing it to keep moisture out of the cracks and keep it from breaking down any further. Anyone that has insight into this process I would truly appreciate.

Thank you for taking the time to read everything and provide me with insight.
 
On the faux rocks - no repair will make it as good as new. Pick your poison as each method will leave you will problems to deal with in the future.

It looks like your pebble used palster with organic coloring which is less expensive for a builder. Insist on a full chip out and inorganic colors for your new plaster job.

Not All Color Pigments are Good for PoolsIt appears the plaster products that contain “organic” pigments become bleached (loss of color) over time when subjected to chlorine (an oxidizer). But products with “inorganic” pigments generally do not become bleached. Additionally, experiments which subjected both organic and inorganic pigments to LSI aggressive water showed that neither type of pigment lost their color from etching.

Thanks, I was trying to figure out if there is a forum search? I really need to make sure I get the water chemistry down solid now that I am putting in new plaster. I have a salt system and for the last 7 years all I have really had to do is keep the PH correct, shock on occasion, keep the CYA level up by manually adding CYA, and keep enough salt in. I haven't really paid much attention to things like total hardness or calcium.

I might just let the last guy I talked to do the stain rather than the paint the first guy was going to use, then seal it to keep water out of the cracks. If it needs to be repainted/stained in 5-7 years I will sand blast it off if I need to. Would likely only take me a half a day to do it and I have a 100lb sand blaster.
 
Search should be on the top bar depending on what device you are using.
