A $150 kit and a Saturday, or a $3,000 professional floor? We've ground off enough DIY floors to know how it usually ends — but we'll also tell you when the kit is the right call.
A hardware-store garage floor kit is a water-based or low-solids epoxy paint, a bottle of citric or muriatic acid etch, a bag of flake, and instructions that say 'clean and etch the floor.' Applied as directed, it goes on about 3–5 mils thick — roughly the thickness of two coats of wall paint — over concrete whose pores were never really opened.
| DIY kit | SwiftHand full system | |
|---|---|---|
| Materials | $150–$400 | Included |
| Grinder rental & tooling | $150–$300/day (if you grind — most don't) | Included |
| Your time | 1–2 weekends | 1 day, ours |
| Thickness | 3–5 mils | 25–35 mils |
| Expected life | 1–3 years | 15–20+ years |
| Removal when it fails | $500–$1,200 to grind off | — |
| Warranty | None | 15-Year transferable |
| Total over 10 years | $1,500–$4,000 and three weekends | $2,200–$3,800 once |
If you're selling the house in a year and want it to photograph well, a kit can be worth a Saturday. If the garage is a bare shell you'll finish properly later, a penetrating sealer or densifier is a cheap DIY that helps. And if you have access to a real diamond grinder, a 100%-solids epoxy and a polyaspartic clear, a careful DIYer can build a decent floor — it's just not the box at the hardware store.
Planetary diamond grinders with HEPA extraction, moisture testing, two-part polyurea repair products, contractor-only resins with a 20-minute pot life that punish hesitation, and the reps to get full flake broadcast right the first time. The chemistry is fast; the skill is in the sequence and the speed. See the process.
Only after grinding it off. New coatings bond to concrete, not to a failing kit, and removal is included in your quote.
Yes. We grind anyway, which removes the etched layer and the salts it left behind.
Usually $500–$1,200 for a two-car garage as a standalone job, or included when we're installing a new floor.
