Garage Floor Epoxy in Dublin, CA

Garage floor epoxy is the job we do most in Dublin, CA. Census estimates put the median Dublin home at about 20 years old, so most garages here have a slab in decent shape that has started to show wear: oil spots under the engine, gray tire tracks, dust that never quite goes away and a few hairline cracks. A coating seals that concrete, makes it easy to wipe down, and turns the garage into usable space for a gym, a workbench or storage.

Newer slabs still need real prep

Many Dublin garages have never had anything on them except what the builder applied. Curing compounds and clear sealers are common on new concrete, and resin will not bond to them. If someone rolls epoxy over a sealed slab, it can look fine for months and then peel at the tire paths. We diamond grind the entire floor, including the edges along the walls and the area under the water heater, to remove that surface layer and open the pores. Then we vacuum every bit of dust before the first coat.

Hot tires and afternoon sun

Pleasanton, right across I-580, averages 89°F highs in July and August, and Livermore has reached 116°F. Tires coming off the freeway in that heat are hot, and a thin coating can soften and stick to them, which is called hot tire pickup. A thicker, fully cured system resists it. Sun is the other issue. A west-facing garage with the door up all afternoon puts UV straight onto the floor, and HomeGuide rates epoxy's UV resistance as poor to fair. We use a UV-stable topcoat so the front of the floor does not yellow ahead of the back.

Signs your garage floor is ready for a coating

• Oil or coolant stains that have soaked in
• Dust that comes back after every sweep
• Hairline cracks along or between control joints
• A store-bought coating that is peeling where the tires sit
• Rough or pitted patches near the door from water runoff
• You want to use the space for more than parking

Cracks on Tri-Valley slabs

A PG&E environmental report on the Tri-Valley rated the Diablo and Pescadero soils at its Dublin site as high shrink-swell, and the Calaveras Fault runs through or near Dublin. Garage slabs crack as a result, usually in thin lines that are stable. We grind those open, fill them with a repair material and coat over them. Wider or offset cracks get a closer look, and we tell you if one appears to be moving before you spend money coating over it.

Picking the look

The most popular finish in the garages we see is a full flake broadcast, because it hides dust and tire marks between cleanings and adds grip when the floor is wet from a car that came through the rain. Solid colors with a light flake give a cleaner, high-end look. Either one gets a clear topcoat. We bring flake and color samples so you can see them in your own garage light.

Townhome and attached garages

In many Dublin townhome communities the garage opens onto a shared drive, and the floor is the only real storage space. We plan where your cars will go during the cure, keep dust contained with vacuum-attached grinders, and work within any hours your HOA sets.
