Starting an epoxy countertop business: what's different from floors, what transfers, and what it costs

An epoxy countertop business coats kitchen counters, vanities and bar tops in place, over the existing top or a new substrate such as MDF, with a thick, self-leveling pour that can look like marble or stone. It shares its chemistry with floor coating, but the work is different: roughly a gallon of resin for every 20 square feet, poured inside a lived-in home and judged from arm’s length. Startup costs are lower than for floors because there’s no grinder or dust extractor to buy; the hard parts are the skill, the several visits each job takes, and pricing small jobs. Installed epoxy countertops typically cost $50–150 per square foot, or about $1,500–6,000 for a kitchen.

How countertop work differs from floors

What transfers from floor coating

• The data sheet. Mix ratios, batch sizes, pot life and recoat times come from the technical data sheet. One widely sold countertop epoxy mixes 1:1 by volume for two minutes, in batches of up to a gallon, with 45 minutes of work time.
• Conditions. Countertop products have narrow windows (the same product wants 68–75°F and 55–65% humidity), and the dew point and amine blush work as they do on floors.
• Prep discipline. Abrade, clean, prime, and keep dust and grease off. Poor prep causes failures on a counter just as it does on a slab.
• Color work. Marble and stone looks build on the skills of metallic epoxy floors: pigments, metallic powders and moving the color while it’s wet.
• Safety and the business side. Protective gear and ventilation, job costing, contracts, warranties, insurance, photos and reviews all work the same way.

What you’ll have to learn

• Edges and drips. A flood coat runs over the edges. The edge has to look as good as the top, and drips have to come off the underside before they harden.
• Level. A self-leveling pour flows to the low side, so check the top with a level and correct it before you pour.
• Design. Customers buy a look from photos. Practice on sample boards until you can repeat it.
• Bubbles and dust. Bubbles are popped with a propane torch, kept moving and away from plastic sheeting, with a fire extinguisher in reach. Dust that lands in the wet coat stays there.
• Working in a home. Protect floors and cabinets, remove or mask the sink, faucet and cooktop, and agree in writing on the days the kitchen is out of use.
• What the finish can take. One widely sold product is rated for brief contact up to 450°F, yet its maker still recommends trivets. Knives scratch it; wine, mustard and turmeric can stain it; heavy-use tops need sanding and a fresh coat every 6–8 years.
• Food contact. Use a product whose maker states it’s safe for food contact once cured, and follow its full cure time.

A typical resurfacing job, step by step

These steps follow a typical countertop epoxy system; where your product’s instructions differ, follow them.

1. Inspect and measure: level, chips, loose laminate and water damage; the tops and the edges.
2. Protect: floor protection board, 3-mil plastic over the cabinets, tape under the edges; remove or mask the fixtures.
3. Sand: 60 grit on existing tops, 220 on raw wood.
4. Clean: a degreaser or 91% isopropyl alcohol, never a solvent the maker rules out.
5. Prime: on laminate, stone or solid surface, two coats of bonding primer and two of undercoat, sanding lightly between coats; on raw wood, two or three thin seal coats of epoxy.
6. Color coat: about 2–3 ounces per square foot for a hand-worked marble look, or 4–6 for a heavier poured design; torch out the bubbles.
7. Flood coat: after 24 hours, sand and pour clear epoxy at about 2–3 ounces per square foot, or apply a topcoat.
8. Finish: clean the drips off the undersides, pull the tape and clean up. Light use after 24 hours; full cure at 30 days.

What it costs to start

That’s well below a floor business, where a dual-disc grinder and a mid-size HEPA dust extractor alone cost about $12,400 new. If you already run floors, adding countertops costs mostly training and practice material. Put the numbers into a business plan before you spend, and pick a name that leaves room to grow (see epoxy flooring business names).

Pricing a countertop job

Price countertops the way you price floors: materials, labor, a share of overhead, then profit (see how to price epoxy flooring). This example uses the wage rates and overhead from our floor example, minus the grinder and dust extractor, which leaves $30,004 a year; over 80 jobs, that’s $375.05 a job. Both jobs resurface existing tops.

Two things stand out:

• Per square foot, countertops price at 10–20 times a garage floor ($6.35 in our floor example). The resin goes on much thicker, and a small area takes hours of hand work over several visits.
• Small tops cost almost as much to do as big ones. The vanity has a quarter of the kitchen’s area but more than half its price, because the visits, setup and overhead don’t shrink with the top. That’s why installed prices span $50–150 per square foot. Set a minimum job price.

Use your own prices, hours and job count: fewer jobs put more overhead on each one, and countertops added to a floor business share overhead you already pay. These are illustrations from stated assumptions, not a promise of income; see the earnings disclaimer.

Contract, warranty, insurance and licensing

• Scope: which tops, edges and backsplash, who handles the sink and faucet, and how many days the kitchen is out of use (see epoxy flooring contracts).
• Warranty: adhesion and workmanship covered; heat marks, cuts, stains and harsh cleaners excluded; care instructions in writing (see epoxy floor warranties).
• Insurance: tell your agent you work inside homes, with a torch (see epoxy flooring business insurance).
• Licensing: some states license home improvement work above a dollar threshold, and countertop resurfacing can count. Check before you quote (see license requirements by state).

Floors, countertops or both?

• Countertops need less equipment and capital and keep you indoors, but every job is small, design-driven and done inside someone’s home.
• Floors need a grinder, a dust extractor and more capital, but each job covers hundreds of square feet with systems you repeat.
• Both: countertops are interior work, so they can fill a floor business’s cold months, when unheated garages are too cold to coat (see the epoxy flooring slow season). Starting part-time? See epoxy flooring as a side business.
