Introduction
Restore a pitted concrete garage floor with an easy-to-apply resurfacing product. It'll make the floor look fresh and new again at a modest price.If your concrete garage floor is suffering from pits, craters or cracks, you can cover up those scars with just a few basic concrete skills. Here is your guide to seal cracks in concrete garage floor. Concrete “resurfacer” is a cement-based coating that forms a smooth, new surface right over the old concrete. The cost of a resurfacer for a two-car garage is typically less than $200. You’ll also need to buy or rent some special tools, so expect your total cost to be about $300.
Cleaning the garage and resurfacing the floor usually takes one day (on the other hand, clearing out your garage so you can work may take weeks!). Spreading the resurfacer smoothly is the trickiest part of the project, so it helps to have some experience with concrete or drywall finishing. Cool weather, with temps in the 60s, also helps. Warmer weather makes resurfacer harden faster, reducing the time you have to finish the surface.
As a first-timer, you might achieve a perfectly smooth, flat finish on your garage floor. Or you might end up with a few rough spots and small ridges. But even if your work is far from flawless, you’ll still make a bad floor look much better. And remember this: If you make some major mistakes, you can add a second coat—this time with the benefit of experience.
Materials needed
- Resurfacer: We used Quikrete Concrete Resurfacer (about $20 for 40 lbs.). Similar products, such as Sakrete Flo-Coat, are available. Buy enough to resurface the whole floor. To estimate the amount you need, check the label and then buy two or three extra containers. Better to return some than to run out before the job’s done.
- Plastic sheeting: Protect walls with a band at least 3 ft. high. We used 6-mil plastic, but lighter stuff will work too.
- Brush and push broom: A stiff brush designed for stripping decks and mounted on a handle (shown) will keep you off your knees ($10). So will a push broom; get a push broom with the stiffest bristles you can find.
- Squeegee: Get a beefy version designed for floors, not a lightweight window-cleaning tool.
- Mixing equipment: A powerful 1/2-in. drill and a mixing attachment are the only way to go. Mixing by hand is too slow.
- Protective gear: Rubber boots and gloves protect your skin against the degreaser and resurfacer (which can burn skin). You’ll also need eye and hearing protection. You’ll need a pressure washer, concrete cleaner (like Quikrete Concrete & Stucco Wash No. 8601-15), a brush, push broom and a floor squeegee. Buy enough concrete resurfacer material (such as Quikrete Concrete Resurfacer; 40-lb. bags) to coat the entire floor. Refer to the coverage specs on the bag to determine how many bags you need.
Everything you’ll need for this project is available at home centers.
