A Wexford homeowner reached out to Invicta Concrete Coatings with a faded, chalking concrete pool deck that had been quietly losing the fight against Western PA weather for years. The 650 sq ft surround on an in-ground gunite pool had visible cracks at the steps, rust staining from old ladder anchors, slick spots near the diving end, and a washed-out gray tone that no longer matched the rest of the backyard. Our crew resurfaced the entire deck in a single working day using a polyurea base coat, a full broadcast flake in a warm sand blend, and a polyaspartic top coat. The deck was walkable in 24 hours, fully cured for chlorine and pool chemistry in 48 to 72 hours, and ready for the family before Memorial Day. The system is backed by a 15-year warranty.

The Challenge
The deck had been installed when the house was built, then sealed once and never touched again. By the time we walked it for the on-site quote, the slab was showing every Western PA pool deck failure pattern at once:
- UV fading and chalking. The original gray concrete had dulled to a washed-out finish, with a powdery residue when wiped.
- Hairline cracks at the steps and corners. Freeze-thaw cycles over multiple winters had opened thin cracks at the highest-stress points.
- Rust staining from old ladder anchors. The previous ladder had been removed years ago but left orange-brown stains that no amount of cleaning had touched.
- Slick spots near the diving end. Algae buildup in the wettest section had glazed over the concrete, creating a real slip hazard underfoot.
- Salt and snowmelt damage at the perimeter. Winter runoff from the house and adjacent walkway had pitted the outer edge of the deck where snow piled up.
The family was using the pool less and less because the deck looked bad and felt worse on bare feet. They wanted a single, durable fix that would handle Western PA weather and look finished. Replacing the slab was on the table, but the structure was sound. The damage was all on the surface.
The Solution
For a Wexford pool deck with intact structure and surface-level damage, resurfacing with a polyurea polyaspartic system for outdoor concrete was the right call. Three factors made it the clear choice over alternatives:
Polyaspartic is UV-stable. A pool deck takes overhead sun all summer. Epoxy and most paint systems yellow or fade within a few seasons. The polyaspartic top coat we installed will hold its color through year 15 and beyond.
Polyurea flexes with the slab. The hairline cracks at the steps were going to keep moving through future freeze-thaw cycles. A rigid coating would crack along with them. The polyurea base is elastomeric, so it stretches and compresses with the concrete underneath.
Full flake broadcast hides existing damage. The rust staining, salt pitting, and chalked surface all disappear under a fully broadcast flake layer. A solid color top would have telegraphed every imperfection. The warm sand blend the homeowner chose also runs lighter than the original gray, which keeps the deck cooler underfoot for bare feet in July.
We also confirmed during the quote that the pool itself would not need to be drained. The coating goes on the concrete deck only. The pool stayed covered through install day.
Installation Day Walkthrough
The crew arrived early on a clear May morning. The full 650 sq ft project broke down into four stages across one working day:
Morning, hours 1 to 3. Furniture and the pool cover were moved clear of the deck. Industrial diamond grinders opened the concrete surface so the polyurea could bond chemically rather than sitting on top. The grinders also removed the chalked top layer and gave the rust-stained ladder anchors a fresh profile. Hairline cracks at the steps and corners were ground out to clean, sound edges. The slab was vacuumed and inspected.
Late morning, hours 3 to 4. Crack repair compound was troweled into the prepared cracks and the widened expansion joints. The patching compound was fully bonded and ready to coat over within minutes. Rust-stained areas were treated to neutralize remaining iron oxide before the base coat went down.
Midday, hours 4 to 6. The polyurea base coat was rolled across the entire 650 sq ft surface, including the perimeter edge that had taken the worst salt damage. While the base coat was still wet, the warm sand flake blend was broadcast by hand to a full saturation point. Excess flake was swept up after the base cured.
Afternoon, hours 6 to 8. The clear polyaspartic top coat sealed the flake and locked in the finish. Edges, the threshold at the gate, and the perimeter detail where the deck meets the lawn were hand-detailed. A final walkthrough confirmed coverage at the steps, around the skimmer, and along the diving end.
By the end of the working day, the deck was finished. The homeowner walked it the next morning and replaced the furniture and pool cover within 48 hours.
The Invicta polyurea system used on this Wexford pool deck is four times stronger than epoxy, UV-stable (no yellowing or fading in summer sun), slip-resistant when wet, non-porous and antimicrobial, and backed by a 15-year warranty. A 650 sq ft pool deck install finishes in one day with no return visits required.
The Result
The finished deck took a faded, cracked, salt-damaged surface and turned it into a slip-resistant, UV-stable pool surround that matched the rest of the backyard. After the first month of use, the homeowner noted:
- No more chalk residue tracking onto bare feet or pool towels
- Cooler surface temperature under direct sun, thanks to the lighter flake blend
- Slip resistance even when soaked from splash-out and swimmers exiting the pool
- Rust and salt stains hidden completely under the flake broadcast
- Cracks no longer visible after the polyurea base bridged the repaired joints
- Easy rinse-clean with a garden hose at the end of each weekend
A month into the swim season, the deck still looked the way it did the day the crew packed up. Heading into next winter, the polyurea base will flex with the slab through freeze-thaw rather than fighting it, which is exactly what failed on the original surface.
Why This System Works in Wexford and the North Hills
Wexford sits in the North Hills of Allegheny County, just north of Pittsburgh. Pool decks across the area, from Pine Township to Marshall Township and into Bradford Woods, face the same conditions as nearby McCandless and the rest of the North Hills:
- Direct overhead UV from May through September, with no break
- Freeze-thaw cycles from late November through March that move the slab
- Heavy snowmelt and salt runoff from driveways and walkways every winter
- Humid summer weather that grows algae anywhere water sits
- Chlorine or salt water exposure through the entire swim season
A coating either survives that combination or it does not. Concrete sealers wear off in two summers. Acrylic deck paints chip where furniture sits. Epoxy yellows under UV within the first season. The polyurea polyaspartic system holds for 15 to 20+ years because each layer handles a specific stressor: the polyurea base flexes through freeze-thaw, the flake broadcast gives slip resistance and hides damage, and the polyaspartic top coat blocks UV and chemicals.
For homeowners weighing the system upfront, our breakdown of whether polyaspartic coatings are worth it for patios and pool decks covers the cost-per-year math. For timing a project before swim season opens, see when to coat a pool deck before summer.
