Frequently Asked Questions

HomeGuide's national range for installed epoxy is $4 to $10 per square foot, which works out to about $1,600 to $5,800 for a two-car garage. Polyaspartic runs $5 to $12 per square foot in the same guide. Bay Area labor, builder sealer removal and crack repair can push a job toward the upper end, so we price your floor after seeing it.

At HomeGuide's $4 to $10 per square foot, 1,000 square feet comes to roughly $4,000 to $10,000 for epoxy. A polyaspartic or full flake system on the same area would land higher. Large open floors are often cheaper per foot than small ones, while heavy crack repair or coating removal adds cost.

Epoxy needs a clean, ground slab and can peel where sealers, oil or moisture are left under it. Standard epoxy can take up to a week to fully cure and has poor to fair UV resistance, so it can yellow in sunlight. It is also slick when wet unless texture or flake is added. We plan around each of these on Dublin floors, especially the UV issue.

HomeGuide gives 10 to 20 years for solid epoxy and 10 to 20 years or more for polyaspartic, compared with 3 to 5 years for water-based kit products. How long yours lasts depends on prep, traffic, sun and how the floor is cleaned. A well-bonded floor that is swept and mopped regularly holds up far longer than one that was rolled on over a sealer.

Yes, in most cases. Hairline shrinkage cracks are common on newer Dublin slabs, and we grind, fill and coat over them. If a crack is wide, uneven on each side, or keeps getting bigger, the slab may still be moving, and a coating can crack along the same line. We tell you which kind you have before quoting.

Plain epoxy can amber over time with UV exposure. Garages here often sit with the door open on hot afternoons, so we use a polyaspartic or other UV-stable clear coat on top. That topcoat takes the sun and protects the color and flake underneath.

It depends on the system and the weather. HomeGuide says polyaspartic reaches full cure for vehicles in 24 to 48 hours, while standard epoxy can take up to a week. Warm Tri-Valley weather often speeds things up, and we give you a specific day and time for your floor.

HomeGuide's national range for a two-car garage is about $1,600 to $5,800 for epoxy and $2,000 to $6,900 for polyaspartic. Sealer removal, crack repair and the finish you choose decide where your floor falls. We give a written price after measuring.

The most common cause is a bond problem. Kits usually rely on acid etching, which does not remove a builder's sealer or curing compound, and hot tires then pull the thin coating up. Grinding the slab and using a thicker system fixes both issues.

A smooth gloss coat can be slick when wet. Flake floors have built-in texture, and on solid colors we can add an anti-slip aggregate to the topcoat.

Yes. Stable hairline cracks, which are common on Dublin slabs, are ground open, filled and coated over. If a crack looks like it is still moving, we explain the risk before you decide.

With a polyaspartic topcoat, HomeGuide says vehicles can usually return in 24 to 48 hours. All-epoxy systems can take up to a week to fully cure. We give you exact times for your floor.

For a garage, most people think so. HomeGuide lists decorative flakes as adding about $0.50 to $2.00 per square foot, and in return you get a floor that hides dirt and has more grip than a solid gloss coat.

They have more texture than a smooth coat. If you want even more grip, we use a thinner clear coat over the chips or add an anti-slip aggregate.

The clear coat on top is what usually yellows, not the chips. We use a UV-stable topcoat on flake floors so sunlight through an open garage door does not dull them.

Most garage flake floors take one to two days of work, depending on the prep and the products. With a polyaspartic topcoat, cars can usually return in 24 to 48 hours.

Not directly on top. The old coating has to be well bonded and then sanded or ground before a new flake system goes over it, and if it is peeling it must come off first. We check this at the estimate.

For sun exposure and speed, yes. HomeGuide rates polyaspartic excellent for UV resistance and gives a 24 to 48 hour cure for vehicles. Epoxy goes on thicker and costs less, so many floors use both: an epoxy base with a polyaspartic top.

HomeGuide's national range is about $2,000 to $6,900 for a two-car garage, or $5 to $12 per square foot. Prep and repairs add to that.

HomeGuide gives 10 to 20 years or more for a properly applied and maintained residential polyaspartic floor.

Yes. Its UV stability makes it a good fit for covered patios and outdoor concrete. Uncovered areas need texture for grip and a lighter color to limit heat.

This Old House and Bob Vila both list metallic epoxy at about $5 to $12 per square foot. Complex designs, extra colors and heavy leveling push it higher.

It can, but it shows tire marks, dust and scratches more than flake does. For a garage that parks cars daily, most people choose flake. For a converted garage or gym, metallic is a good fit.

It has a high gloss and can be slick when wet. We can add a fine anti-slip additive to the topcoat in areas that may get wet.

It will be in the same style and colors, but each metallic floor forms its own pattern as it levels. That is part of the appeal. We walk you through samples so there are no surprises.

Plain epoxy is not a great choice in full sun because it can yellow and chalk. For outdoor concrete we use UV-stable systems such as polyaspartic, with texture for grip.

HomeGuide lists epoxy on a 200 to 400 square foot patio at about $800 to $4,000. Repairs, texture and UV-stable topcoats affect where your job lands.

Not when it is done right. We add flake or aggregate texture to every pool deck coating so wet feet have grip.

Lighter colors stay noticeably cooler than dark ones in direct sun. Coatings such as Kool Deck style finishes are designed for this. We help you choose a color that balances heat and dirt.

HomeAdvisor puts commercial and industrial 100% solids coatings at $12 per square foot or more, and heavy-vehicle grade products add 20% to 30%. Large, open floors can come in lower per foot. We quote after a site walk.

Often, yes. We can phase the work so part of the floor stays in use, and we can schedule nights or weekends for many jobs.

A properly cured system with a chemical-resistant topcoat stands up to oil, coolant and most shop chemicals. Spills should still be wiped up, and we match the topcoat to what your shop uses.

It depends on traffic. HomeGuide gives 10 to 20 years for solid epoxy. Forklift lanes wear faster, and recoating them before they wear through extends the floor's life.
