Pool deck resurfacing applies a fresh coating or overlay over your existing concrete deck — restoring appearance, eliminating trip hazards, and reducing surface temperature. In San Antonio, bare concrete in full sun reaches 150°F+. A cracked, faded deck also reads as a neglected property, even when everything else looks great. Most San Antonio homeowners need deck resurfacing when the original Kool Deck coating or concrete starts showing cracking, color loss, and surface roughness that resealing alone won't fix.
Is It Time?
San Antonio pool decks take a beating year-round. The caliche and limestone soil under Bexar County homes expands with moisture and contracts during drought, causing concrete to crack and heave. UV exposure fades coatings and weakens the surface. Here's what failure looks like:
Bare or uncoated concrete in San Antonio's summer sun reaches surface temperatures over 150°F — hot enough to burn skin on contact. A proper cool-coat reduces surface temperature by 25–30°F and makes the deck usable again.
Limestone soil movement creates cracks and lifted sections that are both a safety hazard and a water infiltration point. Cracks that aren't repaired before resurfacing will telegraph through the new coating within a season.
UV degradation strips color and texture from Kool Deck and acrylic coatings over 7–12 years. Once the surface looks chalky and rough, resealing buys time but doesn't restore it. A fresh overlay is the correct fix.
Pooling water near the edge of the deck or along the coping creates slip hazards and accelerates concrete degradation. Deck resurfacing is an opportunity to correct minor drainage issues with proper grading in the overlay.
Our Process
We measure your deck, assess crack locations and severity, review drainage, and present finish options. You receive a written estimate at no cost. We don't quote without seeing it — deck condition varies too much for phone estimates.
The existing deck is pressure washed and existing coatings are evaluated. Failed or peeling coatings are stripped in the affected areas. The goal is a clean, solid substrate that the new coating can bond to permanently.
All cracks and control joints are addressed before any coating is applied. Flexible sealant for control joints, epoxy repair for structural cracks. This step is what keeps the new surface looking good for 10+ years — not just 2–3.
Your chosen finish is applied — spray-applied Kool Deck, hand-troweled decorative overlay, or broadcast exposed aggregate. Color and texture are applied consistently across the entire deck including steps and transitions.
A UV-stable sealer is applied over the finished surface to protect color, improve stain resistance, and extend the life of the coating. Curing takes 24–48 hours before foot traffic. Most deck jobs are complete within 2–4 days.
What You Get
Investment
Pool deck resurfacing in San Antonio typically runs $2,500–$7,000 for a standard residential deck:
What drives cost: deck square footage, extent of crack repair needed, and finish type. A standard 400–600 sq ft pool deck runs $2,500–$5,500 for Kool Deck and up to $7,000 for decorative overlays. We provide free, detailed estimates — no guessing.
Common Questions
Yes, in most cases. Minor hairline and surface cracks can be repaired and overlaid without issue. Larger cracks or cracks caused by active soil movement need to be addressed structurally first. We inspect all cracks at the free estimate and include any needed repairs in the project quote. We don't cover cracks — we fix them first, then coat.
A quality Kool Deck or acrylic overlay lasts 7–12 years in San Antonio with resealing every 2–3 years. Decorative overlays and exposed aggregate last 10–20 years. UV degradation and thermal movement are the main enemies — both are mitigated by quality products, proper prep, and regular resealing.
Most deck resurfacing jobs run 2–4 days: 1 day for prep and crack repair, 1–2 days for coating application, and 24–48 hours of cure time before foot traffic. Larger decks and decorative overlays take slightly longer. We'll give you a specific timeline at the estimate.
Not typically. Deck resurfacing is done on the exterior surface surrounding the pool, so draining is usually not required unless we're also doing coping repair or waterline tile work at the same time. We'll confirm this at the estimate.
