Patio & Pool Deck Coatings in McAllen, TX

Patio & pool deck coatings face harder conditions in McAllen than any indoor floor. Outdoor concrete here sits in direct sun most of the year, takes heavy rain in late summer and early fall, and gets walked on barefoot. Wikipedia lists September as McAllen's wettest month, averaging 4.74 inches, and hurricanes such as Dolly in 2008 and Hanna in 2020 have hit the area. A coating outdoors has to resist UV, shed water and stay safe to walk on when it is wet.

Indoor epoxy is the wrong product outdoors

Standard epoxy is built for indoor floors. HomeGuide rates its UV resistance as poor to fair, and in full sun it can yellow and chalk. A glossy finish is also slick around a pool. For outdoor slabs we use systems made for sun and water: textured acrylic cool-deck finishes, polyaspartic coatings with grip, or decorative overlays with a sealed surface.

Cool-deck finishes

A cool-deck coating is a textured, light-colored finish made for pool decks. HomeGuide's pool deck guide says this kind of coating helps lower surface temperatures and adds slip resistance. It is the most common choice around pools where people walk barefoot.

Polyaspartic and flake on patios

For covered patios, porches and outdoor kitchens, a polyaspartic flake system gives a cleaner, more decorative look. It resists UV and stains from grease and drinks. We add grit to the clear coat to keep it from getting slick when it rains or when the hose runs.

Decorative overlays

Some patios are too rough or patched for a thin coating. A decorative overlay adds a thin cement-based layer that can be textured or stamped to look like stone or tile, then sealed. It costs more but turns a worn slab into a finished surface.

Cracks, drainage and clay

Outdoor slabs crack more than garage floors because they get more sun, more water and less protection. USDA soil descriptions for clay soils on terraces along the lower Rio Grande note cracks that stay open for much of the year, with very slow permeability. Water that sits on a patio or runs toward the house is a problem that a coating will not solve. We look at slope and drainage at the estimate, fill stable cracks, and tell you if a section needs repair or replacement first.

Where we coat outdoors

• Pool decks and coping surrounds
• Covered and open patios
• Front porches and entry walks
• Outdoor kitchens and grill areas
• Breezeways and carports

Keeping an outdoor coating looking right

Rinse the surface regularly, clean up grease and leaves before they stain, and keep pool chemicals in their containers rather than on the deck. Most outdoor coatings need a fresh topcoat after years of sun, and doing that before the surface wears through costs much less than starting over.
