Preparation of the interior pool surface is critical to the long term adhesion of the new interior surface. Over the years, we have determined that removal of the surface material is the most effective process. This can be accomplished mechanically by using air-driven jackhammers or by using Water Jetting technology to blast away the existing surface. Water Jetting or Hydro-Blasting as it is sometimes called, is the future of surface preparation. Used by many industries to clean a variety of surfaces, the system uses a diesel driven compressor to create a 40,000 PSI stream of water that completely pulverizes the existing plaster surface.
Independent engineering studies have concluded that Water Jetting is the best process to remove the surface material while preserving the integrity of substrate.
