    Answer This Question

    Happy to clear things up, Lydia. Rust-Oleum RockSolid Garage Floor Coating is only suitable for interior surfaces and cannot be used on outdoor areas. The coating will haze and discolor as it is exposed to high amounts of UV. -Rust-Oleum Product Support 14

          Happy to clear things up, Gary. Rust-Oleum RockSolid Garage Floor Coating Kit can be applied using a 3/8" nap roller. Using too long of a nap can work unwanted streaks or lines into the coating. -Rust-Oleum Product Support 14

            I am building a new house. Concrete slabs were poured a few months ago. Do I need to grind the concrete before using this product? Also, how long will this last? How often do I need to treat?
            ByAug 15, 2026
            1 Answer | 
            Answer This Question

            Great question, Luis! Yes, the floor does need to be ground or etched before Rust-Oleum RockSolid Clear Garage Floor Coating can be applied. With proper prep and application, this coating will last for years to come. Floors with heavy use, or if a thinner coat is applied, a maintenance coat may need to be applied after a few years. When applying a refresh coat, etching should not be done again, as that is only for bare concrete. - Rust-Oleum Product Support 3

              Can we use it on a wood floor? We want to put it on the floor in our covered trailer
              ByAug 4, 2026
              1 Answer | 
              Answer This Question

              We got you covered! Rust-Oleum RockSolid Garage Floor Coating can be applied to a wood surface such as particle board or plywood. Please keep in mind porosity of wood will greatly decrease the spread rate. Two coats may be needed, and the recoat timeframe is 12 hours. For proper prep, you will need to scuff sand the surface with 80 grit sandpaper. Then vacuum and wipe clean with a dry rag before coating. Do not use the etch that comes in the kit, as this is to be used on bare concrete only. - Rust-Oleum Product Support 10

                We have a very old workshop floor that we want to coat with this product. We need to repair some cracks so we decided that we would grind the floor first. Do we need to clean the floor if we’re going to grind it?
                ByAug 1, 2026
                1 Answer | 
                Answer This Question

                Great question, Maureen! If you mechanically grind the concrete before applying Rust-Oleum RockSolid Polycuramine Garage Floor Coating, you should still thoroughly clean the floor, but you do not need to etch it. After preparation, the concrete should have a uniform profile similar to 150-grit sandpaper and be free of dust or residue. Grinding and etching can create an overly porous surface, which may significantly increase coating consumption and could even require an additional coat. We also recommend removing the etching powder from the work area to prevent it from being accidentally mixed into the coating. — Rust-Oleum Product Support 15

                  Prep first!
                  [This review was collected as part of a promotion.] My biggest piece of advice is to watch a video before jumping in! There’s a lot more prep work involved than I initially expected, and definitely takes some time to get the space ready. Depending on the type of surface that you’re covering this kit may not include everything you need to prep the floor, so make sure you do your research before starting.

                    Drying time misleading
                    [This review was collected as part of a promotion.] This product was easy to mix and pour. We have tested a small area of the garage and I have some thoughts. The color is beautiful. The actual application is not it. I’d rather pay someone to do this. The drying time says 24 hours and is very inaccurate. You need at least 5-7 days for complete drying. This was a very stressful task and not one I recommend unless you have plenty of patience and plenty of time.
                    by
                      Blacked out floors
                      [This review was collected as part of a promotion.] All right, I waited two months before I wrote this review. This product works absolutely phenomenal if you follow the directions step-by-step. Prep is the key. Get a very good degreaser, a power washer, and scrub down the garage thoroughly. Maybe do it twice. then follow the directions for the acid wash. Get a nice brush, scrub it in really good. Let it dry for a couple to a few days. Then buy the concrete patch kit, fill in all the cracks, divots, anything you don’t wanna see now, when laying down the kit, watch a YouTube video on how they do it. You definitely wanna have two people, one person tying in and maybe flaking, the other person rolling. There is enough product for a small two car garage like mine. However, make sure you pour it heavy or you will see through it, specially on porous concrete. Give it a nice thick coat. It will not hurt. Lastly, if you can afford it, buy the extra clear coat kit with the anti-skid and put that on top. Entire project takes about a week cleaning, scrubbing, acid wash, laying down the product only took two hours.

                        Amazing DIY kit
                        [This review was collected as part of a promotion.] I really enjoyed this floorcoding kit. It honestly was a lot easier than I thought too, applied to my garage floor. I definitely had a lot of stain, so I had to prep in order to get it ready, but once it was on there, I was very happy with the adhesion. The temperature outside definitely was the perfect temperature for it to seal correctly, and overall the odor was not too bad.

                          Amazing finish
                          [This review was collected as part of a promotion.] Amazing finish! Applied the Rust-Oleum RockSolid kit in Modern Greige, and the garage floor looks incredible. The high-gloss showroom finish completely transformed the space. Very easy to mix and apply. Highly recommend!

                            Don’t skimp on prep for a great result
                            [This review was collected as part of a promotion.] I read the directions carefully and it worked great! Be sure to take your time to prep exactly as recommended. We thought about not using the decorative chips but ended up using and it turned out well. We let paint sit overnight before moving to the clear coat, so it seems like it cured correctly.

                              Good stuff
                              [This review was collected as part of a promotion.] This is what I started out with! It was really not that hard to use this product. It was a simple roll on process! It didn’t take a long time to apply it either! The drying time it was took the longest! The over all product was great for floor.

                                Excited
                                [This review was collected as part of a promotion.] I can’t quite it this 5 stars because I haven’t used it yet but I’ve heard great things and I’m very excited too. The garage floor is something my husband and I have wanted to do for many years. I hear this brand is great and one of the better diy kits. The dark grey is a nice color and will give the garage great character.

                                  Great product, but it doesn’t cover what it says it will cover
                                  I have a 2 car garage that is exactly 426 ft.² I rented a floor polisher and a diamond etching tool to remove my old coating and prepare the surface for this product. Because I had read that concrete that had been etched will absorb some of this, I purchased two 2 1/2 car kits to cover my 426 ft.² it barely was enough. When it dried it was very blotchy. I called their customer support line and they told me that if I send photos and receipt copies, they will refund me the price of a third 2 1/2 car kit. I applied the third kit and other than the fact that I was covering up the already thrown chips, it came out pretty good. I also wanted to clearcoat the whole job so that I could use the nonslip material in the clearcoat. Since I had already coated the floor with three 2 1/2 car kits, I was hoping that the one 2 1/2 car kit would cover the already coated surface. It did not. By the last third of the garage I was putting it on way too thin just to make it last. It’s a great product, but it doesn’t cover what they say it will cover. To their credit, rust-oleum’s customer service did send me a check for $300 to cover the price of one of the kits.

                                  Thank you for reaching out! Each pouch of Rust-Oleum RockSolid Garage Floor Coating has a recommended coverage of 200-250 square feet. Since grinding is a more aggressive form of etching than the powder that is included in the kit, this can reduce the coverage rate of the coating since the floor will soak up more of the coating. You also want to ensure that you are working within the recommended temperatures and humidity levels, as well as keeping the mixture out of direct sunlight, to help ensure the best workability of the product. We are thrilled to hear that our team was able to assist you with this!
