Fix Rough, Stained Pool Plaster Without Damaging Your System
Dealing with rough pool surfaces, stains, or calcium buildup? Tired of tools that wear out your saltwater system? Our Non-Corrosive Pool Plaster Disc is made just for DIYers like you. Unlike old-school metal-bonded pads that can mess with your pool chemistry and damage salt cells, our disc uses a non-corrosive bonding material that’s safe for saltwater pools and won’t affect chlorine levels or readings.
You can use it dry or wet, with the pool full or drained, to tackle surface problems like calcium nodules, etching, roughness, and light staining (including mineral and organic marks). It smooths out plaster, improves its appearance, and makes your pool much more comfortable underfoot.
Perfect for DIY resurfacing and easy to use with your standard polisher or sander, this disc helps you bring your pool surface back to life, without the costly equipment damage.
Our Pool Plaster Discs are engineered with premium diamonds bonded with a specialized non-corrosive matrix. The pool plaster disc avoids the issues caused by traditional electroplated metal-bonded abrasive pads, which can elevate sodium hypochlorite and sodium hydroxide levels, leading to corrosion, residue buildup, scaling, formation of calcium nodules, and shortening the life of the salt cell. Instead, our matrix bonding material protects your mineral, chlorine, and saltwater systems, ensuring accurate salt cell readings and consistent chlorine production without compromise. It can be used in both empty pools and those filled with pH-balanced water, without affecting salt generator cell readings. No, pool plaster disc residuals will likely not harm a saltwater generator.
The three main causes of rough pool plaster finishes are:
- Ignoring pool chemistry: Neglecting to properly maintain pool chemistry can lead to elevated pH and calcium hardness levels, which will soon manifest on the surface of the pool plaster.
- Acid washing, while providing a swift solution, involves the use of muriatic acid to clean the pool, which can corrode the Portland cement surrounding the pool aggregate. This process can lead to a roughened and compromised finish.
- Salt exposure poses a challenge, particularly in saltwater pools where the salt content can gradually erode the cement in plaster, resulting in a coarse finish. This underscores the significance of comprehending the impact of salt on concrete pool surfaces.
Why Pool Plaster Thickness Matters
When new plaster is applied, it must be at least 5/8 inch thick. This gives you enough material to safely smooth out any rough spots later without damaging the surface. With the right thickness, you can sand down imperfections and still have plenty of plaster left, helping your pool finish last longer and look better over time.
Refresh Your Pool with a Simple 2-Step System
Bring back your pool’s smooth, clean finish with our easy two-step sanding and polishing process. It’s designed to remove common surface issues like calcium nodules, light etching, skin scrapes, and swimsuit snags, leaving you with a safer, better-looking pool that’s more enjoyable for everyone
Start Fresh by Draining the Pool
If you're going all-in on resurfacing, now’s the perfect time to drain the pool and inspect everything under the waterline. Check and repair or replace things like lights, steps, fittings, tiles, anchors, and railings before you refill. It’s the best way to stay ahead on maintenance and avoid future headaches.
Smooth Results, Simple Process
Attach our 7" non-corrosive pool plaster disc to the AG7529 7" hook-and-loop pad on your polisher or sander (max 3500 RPM). This setup ensures full contact with the surface for even, consistent results. Always use the correct-size pad—smaller ones can cause uneven wear and reduce disc life.
Best of all, our discs use a non-corrosive bond, so you won’t deal with rust stains or residue that metal-backed pads can leave behind. Just smooth, lasting results that make your pool look and feel brand new.
Pick the Right Disc for the Job
We make it easy with three disc options, depending on how rough your pool plaster
- WD7070: Pool Plaster Disc NON-CORROSIVE 70 Grit removes light to rough areas while leaving a smooth finish on both walls and floors of your swimming pool.
- WD7120: Pool Plaster Disc NON-CORROSIVE 120 Grit provides a smooth polish finish, eliminating any textured surface to the touch.
Tip: Start with the rougher grit (50 or 70), then finish with 120 for a pro-level smooth finish.
Start & Finish Your Pool Resurfacing Like a Pro
First Step:
Time to get to work! Use the 50 or 70 grit disc you picked to smooth down your pool plaster. This first step removes rough patches, scaling, and trowel marks.
Here's how:
Work in small sections — Start with a 5 ft x 5 ft area.
No need to push hard — Let the tool do the work. Just guide it.
Feel the difference — After a section, run your hand over it. If it’s still rough in spots, go over it again until it feels consistently smooth.
Goal: Remove about 1/16" to 1/8" of the surface to eliminate imperfections and stains.
Once the texture across your pool feels even, you're ready for the final step.
Disc lifespan: You’ll get around 1,500–2,000 sq. ft. per disc, depending on how rough your plaster is.
If working dry:
Every 5 ft x 5 ft section, stop and rinse off the dust with a hose. This helps avoid overheating and keeps both the disc and the plaster in good shape. Too much heat can damage both.
Final Step: Polish for a Smooth, Like-New Finish
Now it’s time to finish strong! Grab the WD7120 120-grit non-corrosive disc to polish the surface and remove any remaining texture.
Here’s what to do:
Work in small areas — Start with about 4 sq. ft. at a time.
Check your progress — After each section, feel the surface. It should feel smooth and pleasant to the touch. If any rough spots remain, go over them again.
Aim for uniformity — Continue polishing until the whole pool surface has a consistent, smooth finish.
Disc coverage: You’ll get around 2,000–3,000 sq. ft. per WD7120 disc, depending on your plaster type.
If polishing dry:
After every 5 ft x 5 ft area, rinse off leftover dust with a hose to keep the disc cool. Overheating can damage both your disc and your pool surface, so take your time and keep it clean as you go.
