Fibreglass Finish Disadvantages
There is more cost
Something to consider if you choose to go the fibreglass route is that it is more expensive than a marbilite.
If you decide to choose a darker colour pool, you have more chance of white wax marks. It is a cosmetic issue that appears with darker colour finishes but they do tend to fade over time.
Some clients experience a slippery surface from the pools, this does depend on the client and their expectations. if you recognise this issue, it can be fixed with a non-slip surface finish.
