Epoxy Flooring in Brownsville, TX

Epoxy flooring in Brownsville lives in damp, salty air. Wikipedia puts the city's average relative humidity at 75.9% for the year, and it barely drops in summer: 73.2% in July, the driest month by that measure. HomeGuide's epoxy cost guide says epoxy should go down between 60 and 85 degrees with humidity under 85%. On plenty of Brownsville days the air sits close to that limit. We test the slab, watch the weather and pick the coating so the floor cures the way it should.

Humidity is the first thing we plan around

Resin coatings react with the air while they cure. When a slab is cooler than the damp air above it, a thin film of moisture can form on the concrete, and a coating rolled over it may cloud, stay tacky or lose its grip. Garages that stay closed all day and then get opened in the evening are a common trouble spot. We take readings for air temperature, humidity and slab temperature on install day. If the numbers are wrong, we change the schedule, move the work earlier in the day or use a product with a wider window. HomeGuide lists polyaspartic coatings as working across a wide range of temperature and humidity, which is one reason we use them often here.

Clay soil and cracked slabs

Most of Brownsville sits on clay to silty clay loam, according to Wikipedia, with alkaline soil and significant salinity in many places. The USDA describes the Harlingen soil series, which was first mapped in Cameron County, as 60 to 75% clay, with cracks that stay open 150 to 210 days in most years. Clay that dries out and soaks up water again moves the slab on top of it. That is why so many local garage floors have long cracks running across them. We fill and bridge those cracks before coating. If a crack is still moving or wider than about a quarter inch, we tell you before you pay for a floor.

Salt, sand and the coast

On the island and along the Laguna Madre, salt is in the air and in the sand that rides in on shoes, bikes and boat trailers. Wikipedia's article on concrete degradation notes that concrete exposed to seawater is subject to both chloride and sulfate attack, and that salts can crystallize in the pores as water dries out. A sealed coating keeps that salty grit on top of the floor, where a hose and a squeegee can clear it. Inland, salty soils can push white residue up through bare concrete. We clean and grind that off so the coating bonds to sound concrete.

Hurricane season and wet floors

Cameron County has a long storm record. Hurricane Beulah came ashore near the mouth of the Rio Grande in 1967, and Hurricane Dolly made landfall on South Padre Island in July 2008, bringing wind and flooding to the island, Port Isabel, Brownsville and Harlingen. Wikipedia also notes that the city's flat ground and slow-draining clay give several neighborhoods a high localized flood risk. A coating will not stop floodwater. It does make a garage or shop floor far easier to wash out after a storm, and it keeps standing water from soaking into the concrete. If a slab has been flooded, we let it dry and test it again before coating.

Systems we install

• Garage floor coatings: a ground slab, a bonded base coat, flake or solid color, and a clear topcoat that wipes clean.
• Polyaspartic coatings: fast-curing and UV-stable, a good match for open garage doors and humid install days.
• Metallic epoxy: a poured, marbled finish for living areas, offices and retail floors on slabs.
• Patio and pool deck coatings: textured, lighter-colored finishes for outdoor slabs in full sun.
• Crack and slab repair: filling and bridging the cracks clay soil leaves behind, on its own or before a coating.
• Commercial and shop floors: thicker systems for forklifts, carts, chemicals and heavy wash-downs.

What a standard install includes

• Moving plan for what stays and what goes out of the room
• Moisture testing and a check for old paint, sealer, oil and salt residue
• Diamond grinding of the whole floor, edges included, with dust collection
• Crack, chip and joint repair
• Base coat, color or flake layer and a clear topcoat
• Written times for foot traffic, furniture and vehicles, and simple care steps for salt and sand

Brownsville is home base. We also work across Cameron County: Harlingen, San Benito, Los Fresnos, Rancho Viejo, Olmito, Cameron Park, Primera, Combes, Palm Valley, La Feria, Santa Rosa, Rio Hondo, Indian Lake, Bayview, Laguna Vista, Laguna Heights, Port Isabel, South Padre Island and Starbase. Floors change as you move east. Inland towns like Harlingen and San Benito sit on heavy farm-country clay, where slab cracks are the main issue. Closer to the Laguna Madre and on the island, the air carries salt, the ground sits only a few feet above sea level and storm flooding is a real concern. Each town page covers what we know about homes and floors there.
