Rock Solid coverage issues

[Greenlawnracing]

I'm closing on a new home next week, and would like to get the flooring down as soon as possible.

Builder states that the three car garage is 560 SF. Sounds a little small to me, but I did find the estimate from my old home which was built by the same builder - 494 SF.

I was about to pull the trigger on two 2.5 car kits from Home Depot. Total advertised coverage is 1000 SF, and appears to be a DIY that my wife and I can do without killing each other.

Almost clicked "buy" when I saw the terrible reviews - appears that many folks have had significant coverage issues.

Certainly don't think that any kit can truly do 500 SF, but claims and pictures of up to four kits for a two car garage certainly have me worried.

Did a quick search on GJ and didn't find a lot of info on this kit, other than that Rock Solid has a good reputation.

Any experiences or feedback on this alleged issue?

I'm also happy to consider other options in the $400 range. From a DIY perspective, I'm only familiar with the big box brands - Epoxy Coat and Rustoleum.

Side note: I had Rustoleum in my old house - believe I used a 2.5 and a one car kit. However this was almost four years ago, and I don't recall which version I had. I'd assume the cheap water based kit, but don't recall nor do I have the receipt as it was provided by the builder.

Follow up question - what is the difference between the Rock Solid and Epoxy Shield Professional? Both appear to be solvent based.

I just used Rock Solid, followed their instructions because I only had a few days with no cars in my garage. 18x20 garage so one 2.5 garage kit should have covered. I timed my usage, measured so I knew how much to apply. It looked great, put the chips per their info on and then it dried. As it dried it really soaked into some areas. I wished I had put down one coat, no chips, then second coat with chips. I could have added another color coat over the chipped coat, but didn't want the bumpy look. I did cover it with two packages of the Rock Solid clear coat and probably could have used a third kit. Buy more kits than you need and return. I recoated after 10 hours, though you have up to 7 days. I ended up using the clear coat to make it easier to clean. The kit was easy and I am happy. The clear coat kit does not include rollers so be sure to get them if you decide to use it.

i 2nd what Haasepm said. Buy more and return what wasnt used. I also did the top coat because i heard of bad coverage and peeling. (again, buy more and return unused)
Bit of advice on clear coat, have lights, lots of low lights so you can see the sheen of the applied product. It goes on clear and dries clear. I swore over and over that I had 100% coverage then to find out i had about 4 good size spots I had missed after it dried.

If you shop around Menards usually has the best price, but Amazon aslo has a decent price

We did a long article on RockSolid.

The number one complaint is coverage issues. Though the RockSolid polycuramine formula is a 96% solids, it still goes on very thin (dry film thickness of approximately 3 mils) and it penetrates concrete very well. Unfortunately, this combination of characteristics produces a single coat floor coating that can look blotchy in areas. This is a result of more porous areas of the concrete absorbing more of the coating which creates a matte and almost translucent finish (coating too thin) in those areas.

Polycuramine is more expensive compared to some of the other DIY home improvement floor coating kits and I believe RockSolid (Rust-Oleum) made the mistake of listing coverage rates that are too generous in order to try and keep cost of the product more in line with its competition. Combine that with customers who try and stretch the coverage rates out (two 250 sf. kits for a 550 sf. floor for example) and it's a recipe for disaster.

We have started to suggest reducing the stated coverage rates by 15-20% if you want a nicer looking single coat coverage. Either that or just go with two coats. Interestingly enough, because RockSolid penetrates so well, I don't think we have received one complaint from a reader stating that they have had problems with RockSolid peeling.

My suggestion if you are thinking about two coats of RockSolid is to purchase a single-part polyurea coating instead. We did a good article on them that is worth reading. They have so many more benefits over polycuramine.

Many of the vendors on this forum sell single-part polyurea coatings. They are a much better value in the long run compared to the store bought home improvement kits and you get much better customer service and application advice than you will with the other kits as well.

I have a two car garage, house is about 10 years old, garage floor has never been coated.

I decided on the Rocksolid coating and did some reading.

Wow. From all the horror stories about coverage I decided to play it safe and bought 2 2.5 car garage kits.


As for floor prep I pressure washed it then rented a concrete polisher with diamond bits from HD and spent 5 hours creating a **** load of slurry, followed by close inspection and filled every crack with Rustoleum crack repair stuff.

After sanding I rinsed it again and vacuumed the floor.


I spread it thin and had 30% of a bag remaining!


Tomorrow I will take the unused kit back to HD.

YMMV

That’s great that you got good results. The only question is that when you spread a coating too thin you don’t get the protection you may desire or be needed as durability is highly related to thickness.

Hopefully you will be fine but you can always re-coat if needed in the future.

Time will tell, I guess.

I am very impressed with how glossy it is - hard to believe it might be too thin.
