Finishguy, Thanks for you post. How wouuld you strip two layers of RiverRok plaster? Is this a blasting (sand, shot, ot other) operation of a chipping operation? What is done once down to the gunite - I assume the porosity of the gunitie will not be there as it must have plaster embedded? Do you then prep with a primer? The contractor did not acid expose the plasetr until the next day I I feel this was one major issue. Thoughts? It did not seem to expose well, then after haveing to do it several times there were areas that appear overexposed - the aggregate is more tan 1/2 exposed - ie ready to fall out. The other main issue was that the aggregae did not seem to bee evenly distributed. It appears that there were area where they used paste to feather in an area and when exposed left patches where ther was no aggregate. My biggest issue is not knowing what is acceptable and what is common. For example. I have 5 steps down that are about 6' in length. The gunite applicate had a nice even step, but after the plaster was done there was a considerable wave to the edge of the step - in excess of .75". Again the contractor has been good - but I feel I need to tell him to get another sub for the plaster. These guys have been doing plaster only for years, but not the River Roc product. Any comments would be appreciated.

I have recenly had a new inground pool installed. The plaster used is River Rok. The pool contractor used a sub-contractor to apply the plaster. Pool is in mid-Atlantic region. The initial plaster job was horrible - worst the contrcator had seen. They preped the plaster by applying a tie coating (epoxy with grit), removed plaster near the tile and fittings, and reapplied the plaster. Again - very poor job. Everyone agreed it should be redone for a third time. My questions are as follows: What are the long term risks associated with a 3rd replaster? Delaminations? Should I insist on removing previous layers to the gunite? I have withheld some money but not enough to strip the pool and replaster. The contractor is very supportive and agrees to correct the pool to my satisfaction. Should I not allow him to use the same sub contractor again even though he wants to? HELP
