Repair, Resurface & Refinish Concrete Garage Floors

Garage floors are concrete slabs that get treated like junk drawers. Hot car tires, oil drips, dropped tools, road salt, and standing water all combine to crack, stain, and pit the surface. We don't sell epoxy systems directly, but we fix the concrete underneath them—grinding, patching, crack sealing, and prepping the slab so any coating you choose actually lasts.

Most garage floor repair jobs start with diamond grinding to remove the curing-paint glaze and any contaminated top layer. From there we patch with polymer-modified mortar that bonds at 4,000 PSI, fill cracks with semi-rigid polyurea, and re-cut the control joints so future cracks form where you want them. The floor is then ready for any sealer or coating you want to apply. Call us at (206) 555-0182 for a free, written estimate.

FAQs

Garage Floor Repair
Questions, Answered

Honest answers from a hands-on concrete crew.

We prep the slab to manufacturer specs but we don't install coatings ourselves. We work hand-in-hand with epoxy and polyaspartic installers in Seattle—our concrete prep is what makes their coating warranty valid.

Yes. Spalled door thresholds and crumbling driveway aprons are some of our most common garage jobs. We saw-cut a clean line, demo the damaged concrete, and pour a full-depth fix that won't crumble again.

Diamond grinding removes about ⅛ inch of slab in one pass, which clears most penetrating stains. Deep oil stains may also need a degreaser scrub before grinding for full removal.

A two-car garage with normal cracking and surface prep is typically a one-day job. Add half a day for major patching or pothole work. The floor is ready for coating the next morning.
