Rough Pool Surface Cutting Feet and Swimsuits

What It Looks Like

The interior surface of your pool feels like sandpaper. Running your hand along the walls or floor catches and scrapes your skin. Kids complain about scraped toes. Swimsuits snag or develop pilling after a few swims. You might see the surface looking pitted, rough, or eroded compared to the smooth finish it once had. In some cases, you can see exposed aggregate (small pebbles or sand) poking through what used to be a smooth plaster layer.

What Causes It in Central Florida

Pool surfaces in Central Florida degrade faster than in many other regions:

• Aggressive water chemistry: Florida’s high calcium hardness combined with pool chemicals creates a constant battle. Water that’s slightly acidic (pH below 7.2) etches plaster aggressively, dissolving the smooth top layer and exposing the rough aggregate beneath.
• Chemical overuse: Many Florida pool owners over-chlorinate to combat algae growth in our warm climate. High chlorine levels accelerate plaster erosion.
• Saltwater systems: Salt chlorine generators can create localized high-pH zones near the cell, which causes calcium to deposit unevenly. This leaves a bumpy, rough texture.
• Age and wear: Standard white plaster pools last 7-12 years in Florida before the surface becomes noticeably rough. Pebble finishes last longer (12-20 years) but still degrade.
• Improper startup chemistry: If the original pool builder or replastering crew didn’t properly balance the water during the critical first 30 days after plastering, the surface can become rough within just a year or two.
• Algae brushing damage: Repeated aggressive brushing to remove algae from a plaster surface wears it down faster.

How Urgent Is This?

This is a high-urgency problem. A rough pool surface isn’t just uncomfortable, it’s a safety and maintenance issue. Rough plaster harbors algae in its pits and pores, making your pool harder and more expensive to keep clean. It can cause genuine injuries, especially to children’s feet. Rough surfaces also trap body oils and sunscreen, creating staining that’s nearly impossible to remove.

Once the surface is noticeably rough, the degradation accelerates because the increased surface area gives chemicals more to attack.

DIY Options

Honest truth: there’s no real DIY fix for a rough pool surface. You can manage it temporarily:

• Balance your water chemistry perfectly: Keep pH 7.2-7.4, alkalinity 80-120 ppm, calcium hardness 200-400 ppm. This slows further degradation.
• Use a sequestering agent: Monthly doses help prevent mineral deposits from making the rough surface worse.
• Acid wash: A mild acid wash can sometimes smooth a slightly rough surface by dissolving a thin layer of plaster. However, this removes material and shortens the remaining life of the plaster. It’s a short-term fix at best.

There is no coating or product you can apply over rough plaster that holds up long-term in a pool environment. The surface needs to be professionally redone.

When to Call a Pro

You should get resurfacing quotes when:

• The pool floor or walls feel rough enough to scrape skin
• Swimsuits are snagging or wearing out quickly
• You can see exposed aggregate through the plaster
• The pool surface is more than 8-10 years old
• You’re fighting constant algae despite proper chemical maintenance

A professional resurfacing crew will drain the pool, chip away the deteriorated surface layer, and apply a new finish. You’ll choose from standard plaster, quartz aggregate, pebble finish, or other options depending on your budget and durability needs.

What the Fix Costs

Resurfacing costs in Central Florida:

• Acid wash (temporary): $300-$500
• Standard white plaster resurface: $4,000-$7,000
• Quartz aggregate finish (Diamond Brite, etc.): $5,500-$9,000
• Pebble finish (PebbleTec, etc.): $8,000-$15,000
• Mini pebble/polished finish: $7,000-$12,000

Pool size, depth, and current condition all affect final pricing. Most resurfacing projects in Orlando take 5-7 business days from drain to refill.
