    finishing a new old pool, plaster? fiberglass? shallowing


    I have a 17 x 35 play style pool that was constructed in early 2008. Due to many circumstances the pool was never finished.

    The pool construction project stopped right after pre plaster inspection, and has sat in this state since. The pool is shotcrete not gunite. I have always pumped any collected rain water (im in SoCal so not much rain) from the bottom of the pool and have recently pressure washed the entire pool myself using a 13hp 4000 psi pressure washer in preparation for plastering.

    Due to some issues, we would now like to shallow the pool to reduce the slope and center depth of the pool correcting an issue with slope and shell thickness in one area. We would also like to modify the steps then plaster. Our budget is running very thin so I will need to do as much of this work myself. I have a friend with structural concrete experience and think we can handle this portion of the project. The plan is to drill and epoxy additional rebar into the bottom of the pool. We will tie the rebar in a grid similar to what was done during the construction of the pool. we will drill and epoxy pins into the steps to complete the step modification also.

    I am also concerned with applying plaster to this old shell that has been sitting. I am concerned that the shell is so dry that it will affect the curing of the plaster. Is there any other prep work (misting with water for a week prior to plastering?) / coatings that could be applied to reduce the risk of cracking / delamination? The plaster contractors I have discussed this with do not seem to be concerned.

    I have also been reading about fiberglass finishes instead of plaster, this seems like it may reduce some of the issues I may have with plaster.

    Anyone have any opinions / advice for me. Im on a tight budget

    I am not really a plaster expert, but I do know that it is fairly common these days to use a polymer cement bond coat. Other than that, you seem to have things well in hand.

    I don't recommend trying a fiberglass finish. While I have heard of some successful pools done that way, there is fairly few people with the correct experience, and you really need experienced people around when working with fiberglass on that scale. Plaster is much more DIY friendly at this time, with a much larger pool of people available to give advice.
