Resurface Rough Pool Plaster

Before using Pool Plaster Disc

Pool Plaster Diamond Discs made with a NON-CORROSIVE bonding material used with or without water. Our NON-CORROSIVE Plaster Diamond Disc ensures no rust or corrosion stains from residual material. Rough pool finishes known as overexposed aggregate or tool mark can be honed and polished (resurfaced). Pool Plaster Diamond Disc can remove iron stains, organic stains, topical build-up, pool scale Known as Calcium Scale, Waterline scale, and Calcium Nodes leaving a pleasantly smooth finish. Roughness, scaling, and discoloration are topical problems in pool plaster finishes caused by the three most common practices used to maintain swimming pools with plaster pool finishes.

  1. Lack of knowledge or neglect of pool chemistry shown on pool plaster finish. The pool plaster surface is the report card of the water chemistry maintainer. Bad pool chemistry, high pH, or calcium hardness, among others, are seen on the pool plaster surface soon within days or weeks. While other poor practices are more subdued at first before becoming noticeable. Calcium Scale, Waterline Scale.
  2. Acid Washing: This seems to be a common practice for a quick fix. However, muriatic acid eats away at the portland cement surrounding the pool aggregate (quartz, pebble, marble chip, etc.), overexposing it really causing a rough finish, weaker plaster, and most of the time with worst results than prior. Remember portland cement is the base of ALL POOL PLASTERS.
  3. Salt: Saltwater itself from a saltwater pool has issues with attacking cement in plaster over time relating to a rough finish. Read Are Salt Water Systems Bad for Concrete Pools?

Polishing (resurfacing) your rough pool plaster with a pleasantly smooth finish using our two-step process is easy to perform and most of all cost-effective. Whether you have a color quartz finish (Multi-colored plaster) or standard plaster (white), having a smooth pleasant plaster finish is easy and will add years to your existing pool plaster's life.

Manufacturers recommend pool plaster thickness to be a minimum of 5/8 inch thick when applied. So you have some plaster to work with when removing the rough finish.

The two-step resurfacing eliminates calcium nodules, spot etching, skin abrasions, bathing suit damage and will give you a consistent color surface that makes entertaining in and around your pool area a pleasure.

Drain your pool. Now is the time to replace and repair anything below the waterline. Waterline is lights, stair steps, fittings, tile, anchors, railings, etc. We all know that things below the waterline need work at one time or another. So now is the time to do the work.

The two-step process is easy. Using our 7” non-corrosive diamond flexible discs attached to AG7529 7” Velcro pad on a polisher or sander. (Maximum 3500 RPM). Our 7" diameter hook and loop backer pad AG7529 used with our 7" pool plaster disc ensure 100% contact with the pool plaster finish you are resurfacing. (using a smaller diameter backing pad will cause the pool plaster disc to wear uneven and reduce the life of the pool plaster disc) The process will be sanding (resurfacing) your rough pool plaster with our NON-CORROSIVE Pool Plaster Disc.

Start with walls under the waterline tile moving downward, next floor. After ALL, the flat surfaces of the pool are smooth. Start on the inside coves and corners. The disc will work with or without water. Begin with applying the whole face of the pool plaster disc evenly and lightly against the wet plaster. Too much pressure will cause premature wear of the disc and deep swirl marks on the surface. The weight of the tool is all that is needed. You will see that the pad removes the roughness leaving a smooth to the touch finish. When using a pool plaster disc without water it is important not to overheat the disc by doing a 5 Ft. x 5 Ft. area then use a hose to wash off residual material remaining. This will keep the pool plaster disc and pool plaster from overheating. Excessive heat will cause a breakdown in the integrity of both pool plaster disc and pool plaster.
