Rust-Oleum RockSolid Manufacturer Description

It resists salt, oil, gas, and other harsh chemicals. This is one of the toughest floor coatings available. It works great on workshop floors, garage floors, and other interior concrete surfaces. Zero VOCs and a low odor make it an excellent choice for indoor applications. It is easy to maintain and lasts a lifetime while still looking fantastic.
Rust-Oleum RockSolid Review
Application: 5
Rust-Oleum RockSolid coverage was not close to the suggested amount on the box, at about 1/2 or 150 sq. feet per kit. This is a known issue with the brand and product; you will find numerous other online reviews complaining about this problem. We do not like the pouches it comes in, which are prone to leaking. The supplied roller does not hold up and falls apart when used. It took 2-3 days to fully cure and dry.
Gloss Level after Application: 8
After 24 hours of drying, the Rust-Oleum RockSolid gave our test garage a higher gloss shine, but the gloss level was not consistent throughout the garage floor.
Rust-Oleum RockSolid Uneven
Overall Appearance after Application: 6
The Rust-Oleum RockSolid comes in pouches, and when using two different kits/pouches and then applying them, we noticed that the color was not consistent between the kits.
Appearance/Peeling/Wearing After 2 Years: 8
At the 2-year mark, Rust-Oleum RockSolid had lost about 20% of the coating and gloss. There were also numerous scratches on the surface.
Solid Percentage of Epoxy: 9
The Rust-Oleum RockSolid states it is 90% solids by volume. It is better than the other DIY brands, but it still felt “thin” in consistency.
My Overall Score Rust-Oleum RockSolid at 2-Year Period: 7.2
The Rust-Oleum RockSolid is an average garage coating kit marketed to the DIY market. The positives are that it has a higher solid content than any DIY kit you can find at a Big Box Store, and it comes in a high gloss. The negatives are the poor sq. foot coverage and the inconsistent colors between each kit. These issues have been well documented in other consumer reviews. The Rust-Oleum RockSolid holds up slightly better than other brands but still has some wearing issues.

Ii used the rock solid on garage floor. I followed all the instructions. After two weeks and warm weather it is already pealing. It works great on metal though.
I purchased Rust-o-leum Rocksolid floor apoxy and applied it approx 6 months ago. Today, the front half of the garage floor has yellowed because I have the garage door open alot(according to rust-o-leum customer service because the sunand no UV protection). WOW. that was their response with no refund because I didnt keep the itemized receipt. Showed them a bank statement and they said the home depot could get the detail…..thay would not. I had the old box in a pic that i also sent them. DONT BUY THIS PRODUCT….IT IS JUNK AND CUSTOMER SERVICE WONT DOANYTHING…BEWARE
Good Morning
Yesterday I applied Rust-oleum Rocksolid floor, and it looks terrible. Color is very blotchy, with large areas that we can see the concrete below. Do you think I should add another coat of “Restore-A-Garage” or add another coat of Rocksolid?
Actually, you have to remove the Rock Solid to fix it. Grind it off and start over with the Restore-A-Garage.
After the floor dried, there is several spots that are shiner then other areas. Is there a sealant available to reservice, or is there a recommendation to solve the problem
You can add a top coat like this:

What can be used under the tires so when you part a heavy rig on the rocksolid it doesn’t leave tire marks?
Sorry but no idea.
can I use rust-oleum epoxy over rock solid epoxy because we don’t like the colour
Probably not and both are prone to peeling. You should remove and start over with a better brand instead of adding more that will make it harder to fix later.
I hate rustoleum
Rustoleum products are terrible. They came out with the sandless cabinet refinishing several years ago, including a product that was supposed to degloss cabs so you didn’t have to sand them. It sold well, but countless people now have cabinet paint that is chipping and peeling off. I understand why a lot of people have problems with epoxy, as it is tricky to get it right, but the cabinet stuff is very straightforward and easy to understand and do. The problem is, the PRODUCTS in those kits are bad, they just don’t work. And the paint in the kits is… Read more »
Hi there . I used the rock solid clear coat gloss kit , waited a week , looked great .
Went to mop up some shoe marks then it all went Matt in the areas I put any water . Now it is tacky in those areas and dull . I have attached an
Image and am lost to what to do .
Not sure why but this is one reason we never use thier products. You should contact them for help.
Hi I have used the rustoleum Rocksolid paint Grey color for 2.5Garage. After painting the garage, I can see two shades of gray. I tried to contact Rustoleum their customer service is very bad. Not sure now what needs to be done on this. They are trying to give epoxy 9100 which I don’t want. Spent 255 dollars to make dirty garage.
Their products and customer service are not good.
This product peeled in within a few months. Followed all directions. Cheap paint.
I used this Rocksolid epoxy in 2017 and it started peeling within a year. Not happy as it never looked good. Rust-Oleum products are very poor and will never use them again. Their Deck Coating did the same thing at my house and I see they have a lawsuit against them for it.
