New to pools. The home we purchased last year needs rebar repair & re-plastering. Please advise on the actual longevity of the Quartzcapes, Colorscapes, Gemstone type surfaces. We've ruled out the pebble finishes, because of the polarized opinions on them & the cost/benefit doesn't fit our needs. How long have the quartz plaster finishes been around? Is it more for aesthetics? Will the surface of the quartz become more rough as it ages? White plaster was recommended by two of the PB for our needs one recommended an additive to prevent staining (Meta-Max). Any information would be appreciated.
