Hello,
We are in the middle of our long-awaited resurface job and I'm seeing some concerning things. Our old plaster required a total chip out, but the sub contractor did leave what seemed to me like around a 15% coverage of old plaster on the final chipped out surface. Today, the subs cleaned up the debris, rinsed the surface down with water from a hose and applied a dark grey bonding agent called Permakote. As you can see though, they left significant portions of the old plaster unbonded, particularly around the tile line. Based on a video I saw from the National Plaster Council, I think this area is an ITZ prone to etching, so one would think that should definitely get the bonding agent.
I am going to send these pics to the contractor tonight and ask him, but I wanted to get your opinions. This morning when I called him to review what the work would be, he was pretty peeved that I had looked up the application spec sheet on the finish (PMM Marquis Quartz) and questioned that the subs would apply the product to spec. The contract (and the spec sheet) said that they would acid wash before applying the bonding agent, but they did not. The workers said that they do not need to acid wash on a chipped out surface.
So, questions:
1) Should they have chipped out all the old plaster (see pics of the job)
2) Should they have acid washed before applying the bonding agent?
3) Should they have applied the bonding agent in a uniform coat across the entire surface? (the pic with the grey splatters shows the bonding agent application)
4) If those answers are yes, how should I proceed to remedy?
On portions of the old white plaster near the tiles, I can brush off chalky material with my fingers and even find small chunks of plaster that flake off. I'm thinking that is not ideal.
Thanks,
Mike
