We get a lot of calls from people who want their swimming pool “sandblasted” What they really want is the failed coating removed so that they can apply a new coating. Sandblasting in the hands of a good operator can do a good job of coating removal; sand blasting by a less than good operator can end up with substancial damage to the concrete, as had happened with this pool. The concrete in the deep end was severely pitted and the coating was coming off in sheets. Typical for an “after finish” by baking soda blasting is shown in the “after” area in the photo above, or the blue area in the after photo of the pool at right. The deep end of this pool went right to bare concrete as nothing was bonded to the chewed up concrete .The contractor re-coating this pool had substancial repairs to do on those areas – repairs that could have been avoided if the pool had been soda blasted by us when it had been done about two years prior. |
