We called a couple of companies and they all said it was delamination, I think someone mention not using acid or doing some step before applying the resurfacing?I see this pool mainly having a delamination problem, as the plaster is simply falling off the walls without any bonding to the underlying surface.
However, the top step crack is a concern regarding structural or movements problems. But given the other more obvious delamination (bonding failure) situation, I think the contractor just didn't know how to properly perform quality work. I think a good contractor could redo this pool and make it work.
The water heater is not an invasive appliance. I don't see how it can cause that type of damage. It is likely coincidence.This all started to happen when we turned on the water heater and then this blue thing started to come off very slowly from the sides, as it is now is is separated from the side like 5”. I wonder if there is something broken under the pool to make it move when the water heater is on? Could that be something like thT causing it?
They probably did not put a bonding coat on the old plaster before they applied the new plaster. The bonding coat is like paint primer and improved the adhesion between the old material and the new material. Whoever does the work next needs to do the proper surface preparation.I think someone mention not using acid or doing some step before applying the resurfacing?
There was a guy here several years ago - from Europe I believe - who tiled his own pool. And then he had to rip it all out and start over because the adhesive he used failed. He was extremely detail oriented and the pool was amazing.
Someone smarter than I can probably link his thread into here.
Thanks for that info, that is true, If I take this on my own I will have to rent a mixer because I won't be able to do it on my own.If you've ever seen them plaster a pool they have a large truck for the mixing and the spray it out of a nozzle. At least that is what they did on mine. Just mixing that amount of plaster without a machine would be a serious task!
hi there!! I have already made a few post in this beautyful site, that I've stumbled upon from a swedish poolforum a few days ago. I must say that I'm totally blown away by the projects you post in here. It's already yield us inspiration to add what you call a tanning ledge in one part of our...www.troublefreepool.com
The mixer is the easy part. You also need a crew of several skilled plasterers because it all has to be applied nearly simultaneously or it will develop cracks where fresh plaster meets partially cured plaster. You're really better off hiring it out.Thanks for that info, that is true, If I take this on my own I will have to rent a mixer because I won't be able to do it on my own.
Oh my gosh! I read that whole thread last night and my heart just sank when he said the tiles started falling off. So terrible. I bet he never came back to the post because he had a nervous breakdown after that. Terrible.Thanks zea3 - I wish he would have continued posting - it was an amazing build.
