When a pool finish starts staining, roughening or peeling, every Miami homeowner asks the same thing: "How much does it cost to resurface a pool?" Here is the honest 2026 breakdown — what the materials cost, what changes the price, and how to plan your project.
The short answer
A full professional resurfacing in South Florida is quoted per job — most standard residential pools land somewhere between $5,000 and $12,000+ depending on size, surface prep and the finish you choose. If you're a contractor, or a DIY homeowner with experience, the materials alone for a typical 15' × 30' pool with Diamond Brite run roughly $2,000–$2,600 — finish, bond coat and prep supplies.
The materials math (Diamond Brite example)
- One 80 lb bag of Diamond Brite covers 22–25 sq ft at the recommended thickness
- A typical 15' × 30' pool has about 850 sq ft of surface → 35–40 bags
- Diamond Brite Ivory, 80 lb bag: $50.58 → 40 bags ≈ $2,023.20
- Add a bond coat (like Basecrete) over the existing surface so the new finish locks on — skipping this step is the #1 cause of delamination

What changes the final price?
- Pool size and depth — more surface, more bags, more labor
- Surface condition — hollow spots, cracks and old paint must be repaired or stripped first
- The finish you choose — exposed aggregate finishes like Diamond Brite are the best value for the money in Miami: quartz-hard, stain-resistant, and they last 10–15+ years
- Tile and coping — many homeowners replace the waterline tile while the pool is empty (best time to do it)
- Extras — new lights, fittings and a salt system upgrade are cheapest while the pool is drained
Why Diamond Brite is our recommendation
It's simple: Diamond Brite is the customer's best option on price and quality. It's a quartz exposed-aggregate finish — harder than plain plaster, far more resistant to stains and chemical etching, and it comes in colors that hold up under the Miami sun. It's the finish we sell by the pallet to contractors and export customers across the Caribbean.
One thing we explain every week: Basecrete is not a finish. Basecrete is the waterproofing bond layer that goes on the concrete before plastering. Diamond Brite is what gives your pool its color and smooth, durable finish — using Basecrete alone would take far more material, plus pigments for color.
