Pool Resurfacing & Plaster Refinishing
Signs Your Pool Needs Resurfacing
Most gunite and concrete pools need resurfacing every 10–15 years. If you notice any of the following, it’s time for a professional assessment.
Rough or Sandpaper Texture
When plaster wears through, the underlying aggregate becomes exposed — creating a rough surface that scratches feet and swimwear and harbors algae in the pores.
Persistent Staining
Brown, green, or black staining that returns after every acid wash or chemical treatment indicates the stain has penetrated too deeply — only resurfacing removes it completely.
Crazing and Surface Cracks
A network of fine surface cracks (crazing) indicates the plaster has lost flexibility. Left unaddressed, water infiltrates and causes progressive structural cracking.
Delamination and Hollow Spots
Areas where the plaster has separated from the gunite shell sound hollow when tapped. These are structural failures that accelerate water loss and can cause large-section plaster falls.
Unexplained Water Loss
Porosity in aging plaster allows slow seepage through the shell itself — separate from plumbing or fitting leaks. Resurfacing restores the waterproof barrier.
Fading or Discoloration
Plaster that has lost its original color uniformly across the pool indicates the surface layer has worn through. The pool may look dingy regardless of water chemistry.
Interior Finish Options
Your choice of interior finish determines how your pool looks, feels, and holds up over the next decade. We carry samples from all major finish manufacturers.
Entry-level
White Plaster
The classic pool finish: white Portland cement mixed with marble dust. Produces the iconic bright-blue pool water appearance. White plaster is the most affordable resurfacing option but is the least durable and most prone to staining over time.
Water chemistry maintenance is critical — aggressive water quickly etches plaster and shortens lifespan.
Mid-range
Quartz Aggregate
White cement blended with natural quartz crystals. The quartz creates a subtle sparkle and dramatically improved stain and abrasion resistance compared to standard plaster. Available in a range of quartz colors that affect the water's overall hue.
Products include Diamond Brite, Sunstone, and Prism Quartz.

Pebble Finish (Aggregate)
Natural pebble aggregate (river pebbles, Baja pebbles) blended with cement creates a highly textured, extremely durable surface with unmatched depth of color and visual complexity. The water takes on rich jewel tones that shift beautifully with light.
Brands include Pebble Tec, Pebble Sheen, and StoneScapes — each with dozens of color options.
Premium / Statement
Glass Tile (Full or Accent)
Individual glass tile panels or mosaic sheets applied across the entire pool interior or as a high-impact accent (waterline, steps, beach entry). Glass tile reflects light uniquely and is the most visually dramatic interior option available.
Glass tile requires professional installation — grout selection and surface preparation are critical to longevity.
All cost estimates are per square foot of pool interior surface area. Total project cost depends on your pool’s surface area, condition of existing plaster, and tile/coping scope. Visit our Pool Cost Guide for broader renovation pricing context.
Typical surface areas: a 12×24 rectangular pool is ~550 sq ft; a 15×30 freeform pool is ~700–850 sq ft; larger freeforms with tanning ledges or beach entries can reach 1,000+ sq ft. Most Beltway resurfacing projects fall in the $8,000–$22,000 range for standard finishes.
The Resurfacing Process
A professional resurfacing takes 2–4 weeks from drain-down to swim-ready. Here’s what each phase involves.
Drain & Prep
The pool is drained and the surface is sandblasted or chipped to remove all existing plaster. Structural cracks are repaired and the surface is prepped for bonding.
Tile & Coping
Any tile replacement or coping work is completed now, before the new surface is applied. This is the ideal time to upgrade waterline tile or coping stones.
New Surface Application
The finish is hand-troweled across the shell in layers by experienced plasterers, then acid-washed and textured per the selected finish profile.
Fill & Balance
The pool is filled with fresh water. Startup chemicals are added over 7–14 days to cure the surface properly — the chemistry during this period affects long-term finish durability.
Plaster damage compounds the longer you wait.
Porous or cracked plaster allows water to slowly seep through the shell, increasing water loss and chemical consumption each season. More critically, water infiltrating behind the plaster layer causes the shell to deteriorate — escalating a straightforward refinishing job into a structural repair. Resurfacing on schedule costs far less than fixing delamination or shell damage caused by deferring it.
The Startup Period & Your Warranty
The 7–14 days after filling are critical to every plaster and pebble finish warranty. During startup, the pool chemistry must follow a specific protocol: pH, alkalinity, and calcium hardness are balanced in stages, and the surface is brushed twice daily to remove plaster dust before it hardens.
Skipping or delaying startup steps can permanently etch the finish and void the manufacturer’s warranty. Beltway Pools provides a written startup schedule and check-in visits during this window.
Can Coping & Tile Stay During Resurfacing?
Yes — if your coping and waterline tile are in good condition, they do not need to be replaced during a resurfacing project. New plaster is applied up to the existing tile line and coped edge without disturbing them.
However, resurfacing is the lowest-cost window to replace coping or tile — the pool is already drained and crews are already on-site. Many homeowners take the opportunity to upgrade both at once.
Maximize the Renovation
Bundle with equipment upgrades & deck work
With the pool already drained for resurfacing, upgrading your pump, salt system, or lighting is far more cost-effective than a separate visit. View all our renovation services.

How much does pool resurfacing cost in Virginia or Maryland?
Pool interior resurfacing costs in the DMV depend on pool size and chosen finish:
- White plaster — $5,000–$9,000 for a typical residential pool
- Quartz aggregate — $7,000–$13,000
- Pebble finish (Pebble Tec, Pebble Sheen) — $10,000–$18,000+
- Glass tile interior — $30,000–$80,000+ (premium, labor-intensive)
These estimates include draining, prep, surface application, and refill. Additional costs may apply for crack repair, waterline tile replacement, or equipment work bundled into the project. Request your resurfacing quote.
How long does pool resurfacing take from start to finish?
A standard pool resurfacing project follows this timeline:
- Day 1 — Drain the pool (6–12 hours)
- Day 1–2 — Prep the shell (acid washing, crack repair, chipping old finish if needed)
- Day 2–3 — Apply new interior finish
- Day 3–5 — Cure time (plaster typically 24–48 hours; pebble finishes may be longer)
- Day 4–6 — Refill, initial chemistry startup, and balancing
Total project duration is typically 5 to 10 days from drain to swim-ready, depending on the finish type, pool size, and weather conditions. We'll provide a specific schedule before work begins.
What is the best interior finish for pool resurfacing?
The "best" finish depends on your priorities:
- Best value — Quartz aggregate: excellent durability (12–17 years), more stain-resistant than plaster, mid-range cost
- Best longevity — Pebble Tec / Pebble Sheen: natural pebble aggregate lasts 20+ years, produces a distinctive deep-water look, and is our most popular renovation finish
- Most economical — White plaster: classic look but shorter lifespan (7–10 years) and more susceptible to staining
- Most dramatic — Glass tile: unmatched visual impact but premium cost and longer installation time
We bring physical finish samples to every estimate so you can see color and texture options in your actual pool environment before deciding.
How often does a gunite pool need resurfacing?
Interior finish replacement intervals by material:
- White plaster — every 7–10 years
- Quartz aggregate — every 12–17 years
- Pebble Tec / Pebble Sheen — every 20–25 years
Proper water chemistry management is the single biggest factor in finish longevity — pools with consistently balanced pH and calcium hardness will be in the upper range of these intervals. Pools with recurring chemistry issues will resurface sooner. If your surface is showing rough texture, persistent staining that won't respond to chemical treatment, or visible cracking, it's time for an evaluation. Our pool inspection can give you a clear picture of your surface condition.
