Patio & Pool Deck Epoxy in Hillsborough

Water enters concrete through hairline cracks and pores. When temperatures drop below freezing, that water expands and cracks the concrete from inside. This cycle repeats dozens of times every NJ winter. Over decades, outdoor slabs develop a network of cracks and spalled areas. We repair all damage during prep and coat with systems that flex with thermal cycling instead of cracking.

Standard epoxy yellows and chalks within months in direct sunlight. Pool decks and patios are fully exposed. We use UV-stable polyaspartic or urethane topcoats that resist yellowing and maintain their color for years under direct NJ sun. The topcoat chemistry is specifically designed for exterior use, not a modified interior product.

Hillsborough clay soils drain slowly. Water can pool on patios and decks where the grade does not move water away from the surface. We verify the drainage slope before coating and correct low spots so water sheets off instead of standing. Pooled water on a coated surface creates slip hazards and accelerates wear at the pool edge.

Winter deicer and road salt wash off driveways onto adjacent patios and walkways. Chloride exposure pits uncoated concrete and can attack some coatings. We apply systems rated for chloride and salt-brine exposure so the patio surface handles Somerset County winter conditions without degrading.

Wet pool decks with barefoot traffic need controlled texture. We broadcast anti-slip aggregate into the topcoat at a grit level calibrated for wet barefoot conditions, enough texture to prevent slips without being rough on bare feet. The texture is different from what we use in garages or kitchens because the use case is different.
