My customer has a rather large pebble pool about 5 yrs. old that is VERY BADLY scaled. In 25yrs. it is the worst I've ever seen. Trouble is, after washing, washing, washing with 3-1 muriatic, my tender little back went bye bye. This pool will take about 6 days to fill with the well pump and I have a Labor Day deadline. The potential for severe damge from acid washing is so great that I would not trust anyone but the most experienced pro to attempt it.Has anyone got any thoughts or experience bead blasting pebble finishes. I'm thinking that it might be more forgiving than acid and I can relax about letting someone else take the reigns. Your advice is greatly appreciated.

  • You might want to look at www.orendatech.com and view the video on line. Scale can be controlled as well will go back into solution with eco friendly SC-1000. To my knowledge it is the only sequest that is non-hazardous & non-toxic eco-friendly that will control scale and actually disolve existing scale without acid washing the pool! Contains no phosphates and is available from SCP & Superior accross the country.
  • Thanks Jeffrey, We're doing exactly that without the scraping. I've also filled a drum with acid solution and rigged a hose and valve to simplify washing. Acouple of friends are going to help me today and tomorrow. I still can't stand or sit for very long and driving beyond the corner store is awfull. I think I'll set up some shade, fan, and cot and really make them remember the experience!

    We usually scrape the whole pool first with old plaster trowels. You scrape the surface like you are shaving the pool finish. Then a heavy acid wash and pressure wash. We use 4000psi pressure washer with about a 30 degree tip and hold the wand about 6-12" away from the surface. Ypu may have to repeat the process to clear it up entirely, but a pebble finish should put up with the abuse pretty well. The whole process is tedious, but a two man crew can usually get it done in a day. This is for a typical pool in the Buffalo, NY area. (3-8ft dp, 600-700 sq ft surface area)

  • Thanks David.

    After allowing the adrenaline and pain killers a chance to wear off some, I realize blasting with any media, including walnut would likely not produce a positive result. We'll get er done on time somehow.
  • I know my beadblast subcontractor does beadblast pebble waterlines (where there is not tile) all the time... beadblasting the entire pool is going to be PRICEY I would imagine!!! I would think similar to resurfacing pricey, at least out here!
