How the points were given
Each coating is scored on performance, build, value, safety and warranty, with the weights published on our How We Pick page. A stated safety listing or a low VOC formula earns safety points, and a warranty with a stated term earns warranty points.
| Product | Shop Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| RockSolid Black Kit | 9.5 | 30 | 21 | 20 | 3 | 0 |
| KILZ Decorative Gray | 9.4 | 28 | 20 | 18 | 2 | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.
What the listings tell you
Two of the listings give full bullets and spec tables, and the other two give a title only. The full listings state coverage, coats and times, while the title-only kits state a size and a drive-on time or coverage and little else. One listing disagrees with itself on fill size, and one gives two coverage figures that bracket each other, so read the fine print before you count on a number.
Buying guide: the best garage floor coating for concrete
Coverage and coats
Coverage decides how many kits the floor needs. The RockSolid black kit covers up to 250 sq ft in 1 coat, the KILZ gallon covers 50 sq ft with 2 coats, and the Gorilla kit states 550 sq ft. The gray RockSolid kit states no coverage, so its size is the 2.5 car kit only. Measure the floor first, then match the coverage the listing states.
Dry and drive-on times
Plan the job around the times the listing states. The RockSolid black kit takes foot traffic in 8-10 hours and vehicles in 24-36 hours, with a full set in 24 hours. The KILZ coating dries to the touch in 1 hour, recoats in 3-4 hours, takes light foot traffic after 24 hours and is fully set in 72 hours, with cleaning allowed after 30 days. The gray RockSolid kit states vehicles in 36 hours, and the Gorilla kit states no times at all.
Finish and grip
The RockSolid black kit self-levels to an extreme high gloss finish, and the Gorilla kit states a high gloss gray finish. The KILZ coating dries to a textured, speckled, slip-resistant finish that fills hairline cracks, which suits a floor that gets wet or sees foot traffic. Gloss shows the floor, and texture grips it.
Prep and application
Coatings need clean, prepared concrete. The KILZ listing states clean, etched and completely dry concrete, and the RockSolid black kit includes concrete etch and a foam roller. The black kit states a 7-day recoat window without sanding and a 45 min pot life once the pouch is mixed, and it lists 40-90°F for application. The KILZ coating must go on with a 1/4 in adhesive roller. Open the garage door while you work: the RockSolid kit is low odor and the KILZ coating is low VOC.
Use rated jack stands on solid ground, wear eye protection with power and air tools, keep fuel-burning equipment out of a closed garage, and follow the manual for every tool. Read our Safety Disclaimer.
Garage Fit Check
- Match coverage to the floor: the RockSolid black kit covers up to 250 sq ft in 1 coat and the Gorilla kit states 550 sq ft, while the KILZ gallon covers 50 sq ft with 2 coats.
- Plan around the times: the RockSolid black kit takes vehicles in 24-36 hours and the KILZ coating is fully set in 72 hours.
- Check the kit size against the garage: the RockSolid kits are 2.5 car kits and the KILZ coating comes as a 1 gallon pail.
- Keep the floor clear until the stated times pass, and allow 30 days before cleaning the KILZ coating.
