If you’re looking for an affordable and effective way to restore your pool’s plaster surface, our Non-Corrosive Pool Plaster Disc delivers professional-quality results—right from your backyard. Whether dealing with rough textures or unsightly stains, this easy-to-use tool helps you achieve the clean, smooth finish your pool deserves.
Why Pool Plaster Matters Pool plaster serves more than just aesthetic purposes—it protects your pool shell, enhances swimmer comfort, and resists staining and abrasion. Over time, however, plaster can degrade due to: Imbalanced water chemistry Organic debris or metal exposure Harsh acid-based cleaners (like muriatic acid). These factors contribute to surface roughness, calcium buildup, spot etching, and discoloration—potentially requiring costly re-plastering if left untreated.
Non-Corrosive Pool Plaster Disc is the answer. Traditional abrasive pads with metal-bonded materials can increase sodium hypochlorite and sodium hydroxide levels, leading to corrosion, residue, scaling, and calcium nodules. This can be especially problematic for saltwater pools. Our disc utilizes a unique matrix-based, non-corrosive bonding material, ensuring it won't compromise your saltwater system or interfere with salt cell readings, helping to maintain efficient chlorine production. No, pool plaster disc residuals will likely not harm a saltwater generator.
Compatible Equipment. For best results, use a variable-speed sander or polisher that does not exceed 3,500 RPM. Optimal performance is typically achieved at speeds between 2,600 and 2,800 RPM. The tool should have a 5/8" spindle and be equipped with our AG7529 7" Hook & Loop-backed pad, which is designed to securely fit all of our pool plaster discs.
Use Wet or Dry. Effective in both wet and dry conditions, this disc can handle even the toughest pool plaster defects in a simple 2 step repair and resurfacing process. Use it dry to eliminate stubborn calcium nodules and stains, or wet to polish and achieve a smooth, like-new finish. It effectively removes spot etching, calcium nodules, surface roughness, and most visible staining, including [mention specific types, e.g., mineral and light organic staining]. It improves the appearance of your pool plaster, reduces surface roughness by up to 30%, and creates a more comfortable swimming experience.
First: Drain and Inspect the pool completely for best access. Take this time to inspect underwater fixtures like tiles, lights, and railings. Perform any needed repairs before resurfacing begins.
Second: Select the right pool plaster grit for the job.
WD7050 – 50 Grit Heavy-duty removing for rough plaster, trowel marks, or scaling. Leaves a light textured surface.
WD7070 – 70 Grit Heavy to Medium grit for smoothing , some scaling, quartz finishes. Leaves very light textured plaster.
WD7120 – 120 Grit Fine polish for final surface refinement. Leaves a smooth, honed finish.
Step 1. Flatten & Smooth. Start with WD7050 or WD7070 depending on surface severity.
Removes:
Trowel marks
Minor stains
Surface scaling
Aggregate roughness
(Each disc covers approx. 1,500–2,000 sq. ft. Removes approx. 1/16" to 1/8" of plaster. Work in 5 ft² sections. Rinse after each section when using dry. Check smoothness by hand before moving on.)
Step 2. Polish & Refine. Switch to the WD7120 – 120 Grit disc.
Removes:
Light texture
Surface dullness
Minor etching or discoloration
This step produces a comfortable, slip-resistant, visually appealing finish.
Common Issues Our Disc Solves
- Spot etching
- Calcium nodules
- Surface scaling
- Metal and mineral staining
- Skin abrasions and swimsuit damage
Why Choose Our Non-Corrosive Pool Plaster Disc?
