Pool Plaster Diamond Disc are made with an NON-CORROSIVE bonding material and can be used with or without water. This ensures no rust or corrosion stains from residual material. Rough pool finishes also known as over exposed aggregate or tool marks can be honed and polished (resurfaced). Pool Plaster Diamond Disc removes iron stains, organic stains, topical buildup, pool scale (plaster surface build up) also known as Calcium Scale, Waterline scale, and Calcium Nodes leaving a pleasant smooth finish.

Roughness, scaling, and discoloration is topical problems in pool plaster finishes caused by 3 common practices used to maintain swimming pools with plaster pool finishes.

  1. Pool Chemistry: Lack of knowledge or neglect of pool chemistry is shown on pool plaster finish. The pool plaster surface is the report card of the water chemistry maintainer. Bad pool chemistry such as a high pH and/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 becomes noticeable. Calcium Scale, Waterline Scale.
  2. Acid Washing: This seems to be common practice for a quick fix. However, muriatic acid eats away at cement surrounding the pool aggregate (quartz, pebble, marble chip, etc.) over exposing it causing a rough finish, weaker plaster, and most of the time worst results than prior. Remember cement is the base of ALL POOL PLASTERS.
  3. Salt: Salt itself from a salt water pool has issues of attacking cement in plaster over time causing a rough finish.

    Before Using Pool Plaster Disc

    The picture above shows an overexposed aggregate pool plaster surface caused by excessive use of muriatic acid. Pool Plaster surfaces with course sand paper feel will cause skin abrasions, irritation, and bathing suit damage. This can literally make the swimming pool unusable over time. Leaving the pool finish rough and discolored will lead to spot etching, topical stains, permanent scale and algae adhesion. You will have to re-plastering your pool if not corrected.

     

    Polishing (resurfacing) your rough pool plaster with a pleasant 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 in color), having a smooth pleasant plaster finish is easy and will add years to your existing pool plasters 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.

     

    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. Items that you need to maintain below the waterline are lights, stair steps, fittings, tile, anchors, railings etc. We all know that things below the water line 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 4500 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 waterline tile moving downward, next floor. After ALL flat surfaces of the pool are done. Start on the corners. Pool plaster disc can be used with or without water. Begin with applying the whole face of the pool plaster disc evenly and lightly against the plaster. Too much pressure will cause premature wear of disc and deep swirl marks in plaster. The weight of the tool is all that is needed. As you progress you will see the pad take the roughness away leaving a honed resurfaced to the touch finish.

    Disc Selection

    1.) WD7050: 50 Grit NON-CORROSIVE Pool Plaster Disc is used on coarse pool plaster or trowel marks to be removed and leaving a slight texture.

    2.) WD7070: 70 Grit NON-CORROSIVE Honed Diamond Disc is used on semi-coarse pool plaster or when new polished quartz plaster is to be honed or lightly buffed.

    3.) WD7120: 120 Grit NON-CORROSIVE Pool Plaster Disc to removes the slight texture giving a pleasant smooth polish finish.

    Step 1

    Use selected 50 Grit or 70 Grit you selected to clean and hone down your pool plaster to a flat surface. During this step, your going to remove all surface scaling, rough aggregate, and trowel marks. (View before polish plaster finish picture). Start by processing 4 square feet before you stop. Feel the surface you just processed with your hand. Remember not much or no pressure needed. Let the pool plaster disc do the work. You want the pool plaster to have an even slight texture surface. If you feel areas that are smoother than others. Continue till pool plaster surface is consistent. It is important for pool plaster surface to have a uniform texture throughout. By removing the top 1/16" or 1/8" of plaster you have now removed all surface imperfections, stains, and trowel marks. This is the base and start of your new polished (resurfaced) pool finish. Disc coverage approximately 1,500 to 2,000 so. ft. per disc depending on roughness and plaster material being removed.

    Step 2

    Use WD7120 non-corrosive honed diamond disc for final honing and polishing. During this step, you’re going to remove that slight texture feel of the plaster. (View the after polish plaster finish picture shown to see what you will achieve.) Polish about 4 square feet before you stop, feel the surface you just process. It will have a pleasant smooth to the touch finish. Now you will start to feel and see your polished pool finish. If you can feel areas that have texture, continue with the WD7120 pad to get the smoothness you desire. You will make the final decision on how smooth the surface will be. Coverage approximately 2,000 to 3,000 so. ft. per pad depending on plaster material.
