Patio, Pool Deck & Exterior Concrete Coatings
Exterior concrete in Pomona takes the full brunt of the inland climate — intense UV essentially year-round, long stretches of extreme summer heat, and enough winter rain to matter for drainage.
Why Exterior Systems Are Different
UV stability is mandatory. Standard epoxy ambers and chalks under direct sun. Exterior work requires UV-stable polyaspartic or polyurea systems, or the surface discolors within a season.
Surface temperature is a comfort and safety issue. A dark coated pool deck in Pomona in July gets hot enough to be genuinely unpleasant barefoot. Lighter colors and coatings formulated for reduced heat absorption make a real difference here in a way they don't in milder coastal climates. This is worth discussing before color selection, not after.
Slip resistance is a safety requirement. Around a pool, a smooth coated surface is hazardous. Exterior systems need aggregate broadcast or a texture additive to maintain traction when wet.
Drainage has to be respected. Coating over a patio that already ponds water traps moisture against the surface and shortens the coating's life. Slope problems get addressed before coating.
Slab movement. Southern California slabs move — seismic activity and expansive soils both contribute. Exterior systems need enough flexibility to accommodate minor movement without cracking or delaminating, and existing cracks need proper treatment rather than being coated over.
Common Applications
Pool decks and surrounds, back patios, covered walkways and entries, outdoor kitchens, and courtyards.
