How to make a rough pool plaster finish smooth using our NON-CORROSIVE Pool Plaster Diamond Disc?
Are you worried about the rough finish of your pool and want to fix it without spending much money? We’ve got a seamless DIY solution for you to do it well.
For that, you just need to understand why is pool plaster significant and why does it get rough? Although there are different kinds of swimming pool water systems get to know yours. A smooth pool plaster finish is important because it prevents potential damage to a bathing suit, skin irritation, and potential areas for dirt to build in the swimming pool. The pool plaster finish gets rough with time due to out-of-balance pool water chemistry, organic matter that blows into the water and sinks to the pool bottom, other foreign elements and objects that enter the pool, and washing with acid.
The Most Common Cause of Pool Staining is metal corrosive materials or organic debris mixing with the ph levels in swimming pool water. All pads use a corrosive metal for diamond bonding unless specified because of the cost. That causes rust problems from the residuals most of the time after use. Our diamonds are bonded with a NON-CORROSIVE material.
You can use our non-corrosive Pool Plaster Diamond Disc to cater to the problems of roughness or staining in your pool plaster. Since the disk consists of non-corrosive bonding material, you can use with water or not. The pool plaster manufacturer recommendeds to apply the pool plaster thickness to 5/8 inch thick when applied. Our DIY process will help you eradicate spot etching, calcium nodules, skin abrasions, bathing suit damage, and topical staining. It will result in a consistent color surface and will make your pool a pleasant place to entertain.

Before Using Pool Plaster NON-CORROSIVE Disc
The picture above shows an overexposed aggregate pool plaster surface caused by excessive use of muriatic acid. Pool Plaster surfaces with coarse sandpaper 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 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 done. Start on the inside coves and 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 wet 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. When using pool plaster disc without water it is important not overheat the disc by doing a 5 Ft. x 5 Ft. area then use a hose to wash off plaster residual material remaining. This will keep the pool plaster disc and pool plaster from over heating. Excessive heat will cause break down in the integrity of both pool plaster disc and pool plaster.
 
The DIY process of resurfacing your pool majorly consists of only 3 steps followed by some initials. 
 
  1. You first need to drain your pool, maintain lights, stair steps, fittings, tile, anchors, railings, etc. below the waterline. 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).
 
  1. Start with walls under the waterline tile moving downward, next floor. Flat surfaces of the pool will be done then start on inside coves and corners. When using pool plaster disc without water it is important not overheat the disc or plaster by doing a 5 Ft. x 5 Ft. area then use your hose to wash off plaster residual material remaining. This will keep the pool plaster disc and pool plaster from over heating. Excessive heat will cause break down in the integrity of both pool plaster disc and pool plaster.
 
  1. 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 plaster gouging. 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.
 
 
Selecting a Disc
We have three good product options for a non-corrosive disc. 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 whereas, WD7070: 70 Grit NON-CORROSIVE Honed Diamond Disc is used on semi-coarse pool plaster or when new polished quartz plaster is to be polished or needs to be buffed lightly. The third one is 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 polish down your pool plaster to a flat surface. You need to remove all surface scaling, rough aggregate, and trowel marks. Start by processing 5 square feet before you stop. Remember not much or no pressure needed. LET THE PADS DO THE WORK. Feel the surface you just processed with your hand. If the areas are felt smoother than others, continue till pool plaster surface is consistent. Uniform texture throughout the pool is significant. 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 will be approximately 1,500 to 2,000 so. ft. per disc depending on roughness and plaster material being removed. When using pool plaster disc without water it is important not overheat the disc by doing a 5 Ft. x 5 Ft. area then use a hose to wash off plaster residual material remaining. This will keep the pool plaster disc and pool plaster from over heating. Excessive heat will cause break down in the integrity of both pool plaster disc and pool plaster.
 
Step 2
Now, use WD7120 non-corrosive honed diamond disc for final refining and polishing. You’ll need to remove that slightly textured feel of the plaster. Polish about 4 square feet before you stop. The surface now must have a pleasant smooth to the touch finish. If you can feel areas that have texture, continue with the WD7120 pad to get the smoothness you desire. The surface will result in a much smoother one now. Coverage approximately 2,000 to 3,000 so. ft. per pad depending on plaster material. When using pool plaster disc without water it is important not overheat the disc. After doing a 5 Ft. x 5 Ft. area use hose to wash off plaster residual material remaining. This will keep the pool plaster disc and pool plaster from over heating. Excessive heat will cause break down in the integrity of both pool plaster disc and pool plaster.

Get to know that proper pH, alkalinity, and calcium hardness levels are essentials to prevent etching of pool plaster. You can start the process by refilling your pool.
Remember that plaster of your pool is essential. You must monitor changes in the surface to avoid larger-scale problems down the road, practice a consistent pool care routine, keep the water balanced, take care of the chemical levels and try to keep your pool covered when not in use so that stain-causing materials do not affect badly.
