20x21 Rust Bullet Prep Question/Install

Hey guys,

I just closed on my first house last friday and got started working on my garage friday night! I built above the garage storage, painted the walls highly reflective white, and replaced all the plugs and switches in the room.

Now I'm to the point that I'm about to do the floors. The garage is suppose to be 20x22 but its actually 19' 3" by 21'. I received 2 gallons and a quart of rust bullet, 5 lbs of chips, and a gallon and a quart of clear coat.

Now for why I posted, could you all look at my floor and tell me what I need to do for prep before starting? it seems I have some stains all over it and I cant decided if I think its sealed or not.

I tried to clean some of the oil spots with brake cleaner but it doesn't seem to be completely up and probably needs more brake cleaner and scrubbing. Any input, tips, or anything else you can contribute I'd appreciate it.

Here's video and some pictures

I'm not seeing a video. If this was my floor I would lightly grind it with a finer diamond grinder and then use an extra coat. Plan dimensions and finished dimensions are always off.

The video is the first small picture. Just click on it and it will start the 33 second video. Does this floor look sealed to you? Would the rust bullet stick without having to grind it? Where can I rent a grinder?

It looks like I can rent a grinder from Home Depot for a day for $88. Maybe I need to order another gallon of rust bullet and go rent a grinder for a day.

Thanks for your time and answering my questions Justin. I'll keep this updated. I plan to have this done by the end of next week. Grinding on Monday will be the next step.

I went to Home Depot yesterday to pick up the concrete grinder and it was rented out. I ended up going with a floor buffer and a concrete grinding pad. Total cost was $110.64 for a 4 hour rental. It took about 3 hours to complete.

Dust control wasn't bad until we did the edges with the 4" grinder! That thing made a mess! We tried grinding with it wet but it seemed to work better dry.

A few pictures of my dad grinding the floor

Can't wait to see how this turns out - your floor looks a lot like mine and I'm definitely considering rust bullet as an option.

Ok guys the first coat is down!!


It took about a hour to lay the first coat, my dad did all of the cutting in and I did all of the rolling. As you'll see in the pictures below it seems I have some roller marks. I'm guessing that's because it was the first coat. We talked about maybe tomorrow rolling the second coat the opposite direction and then rolling the 3rd coat the same direction as the first. I think the addition of chips will hide all of the roller marks but I'm interested in trying this to eliminate them.

The next coat is going on at 6am in the morning.

Here's a picture of the weather

As for a respirator I thought I ordered one when I put in my order but apparently I didn't. So instead of the $40 one that Lowe's sells I opted for this one. It was over in the paint section at Lowe's for $10 for two of them. With the fan blowing and this mask on a I didn't have any problem with the smell/fumes.

Also for even chip distribution I decided to separate my 5lbs bag into 8 individual bags. I used a quart messuring paint cup and filled it with chips to the 20oz line. This resulted in 8 bags with even amount of chips in it and about a 1/4 of a bag left over in the 9th. This method should help improve even spreading of the chips and not having to worry about running out or using to many in each quadrant. (Since my garage floor is divided in 4 even quadrants)

Please keep us updated on your progress...Rust Bullet is on my "to do" list very soon.

Second coat definitely will go on better than the first, but you guys need to slow down and work in smaller sections. Some of those marks are likely from a roller that was used over a very wide area and not really loaded correctly. That said when you grind the first coat is rough. Watch your coverage. Use a full gallon every 400 square feet.

Double check the respirator and make sure it is the right kind. We don't offer respirators online yet but we do have them.

Lastly I am looking at your post time and the start time for the next coat. Wondering what the humidity is inside. Your max recoat time is based on sub 70% humidity. If its over that our recoat time goes down. I would try and get coat two on tonight do third coat tomorrow followed by clear ASAP

The humidity right now according to the weather app is in the mid 80s. With the garage attached to the house though and being insulated it shouldn't be that high.

So I went up there and did the second coat at about 2am this morning. It took me till about 4 because I was doing it by myself. The roller marks are quiet abit less but still present in some areas. Hopefully with the third coat and the flakes they will be gone. The humidity was quiet high though at 85%.

I'm going back and putting the next coat on at 8am if it's dry enough to walk on by then.

Hey guys,

The floor is now complete!!

The second coat went on at 2am, the third went on at 8am and the 4th went on about noon.

Things I learned/Tips:

- 5 lbs of flake on a 400 sq foot garage is a lot of flake.
- don't put more flake on then you actually want, you'll only "vacuum up" about 10%, most of it sticks.
- a leaf blower will remove more flake than a vacuum if you want to remove some.
- the clear is really thin and impossible to see under my 6500k garage lights, turning off the lights in the garage allowed for easy seeing of the clear during application.
- as you'll see I left the edge in my garage flake free. I perfer that look.


Thoughts:
- if I was to do t again I would use less flake I figured half of what I put in would come up with the vacuum but it didn't. I love the outcome of my floor but if I ever did it again I would use alittle less flake. Maybe 2lbs instead of 5.
- I'm honestly not sure if I could of got it roller mark free with simply leaving it gray. Maybe it's possible for some but wasn't for me. The metallic in the paint caused lights and darks and it was hard to eliminate all of the roller marks while maintaining a uniform color.
- this was a 3 day project and did cost about $2 a square after it was said and done.
- having two people greatly helps and speeds up the process
- following the recoat times is difficult when you need to apply 4 coats. With the humidity levels during the summer time anywhere east or south east it would be impossible to stay under 70% humidity. Apparently last night peaked somewhere around 90%.

Overall I'm very pleased with my flooring and I appreciate Justin from Garage Flooring LLC for answering all of my questions. I plan to take a night picture because they seem to look the best but here's a few pictures from during the day after it was finished.




Here was the weather when I applied the clear:

Overall I'm very pleased with my flooring and I appreciate Justin from Garage Flooring LLC for answering all of my questions. I plan to take a night picture because they seem to look the best but here's a few pictures from during the day after it was finished.

First and foremost the floor looks awesome. You did a really really nice job.

If you have time, I would love to go through some of this with you here, because I think it will help people looking at the product in the future and also, I may need to cover some this stuff better in our instructions -- which goes way more in depth than what is on the cans.

Flake: Our suggestion is 1#/100 Sq. Ft for a good heavy broadcast and no more unless you are doing a full broadcast. Obviously some people prefer less.

Clear: "- the clear is really thin and impossible to see under my 6500k garage lights, turning off the lights in the garage allowed for easy seeing of the clear during application." Your film thickness on the clear and coverage should have been about the same as the gray with some minor differences in dry film thickness based on solvents and anti-slip. So what I am thinking you are saying is that the gray, obviously has color and is easy to see when you are installing it but because the clear is clear it is really hard to keep track of what you have coated?

If that is what you are saying, I would tend to agree. Not only with RB clear but most clears and even second coats. For the installs we did, when the garage door was open we could see the clear. You may have had the opposite problems we had. Our lighting was not enough and I am wondering if yours bleached it out?

Roller Marks: We have had almost no (maybe even no) reports of roller marks in a fully cured floor with the new formulation and the correct roller covers. When grinding or etching, that third coat that you did is very necessary. Do you feel that with a grind a 4th coat was necessary for best aesthetics if you are not doing flake and clear?

Project Length 4 Coats w/ grind You mentioned that this was a three day project and costs were at about $2.00/ Sq. Ft. Is that including a day for cleaning and grinding and costs of grinder rental and sundries?


2 people Personally, I think two people are required on a flake floor.


Re coat times / humidity You are 100% correct. When humidity comes into play and decreases your recoat window it can be problematic, especially when doing 4 coats. We have noticed that the gray is way more forgiving than the clear. We would tend to do two coats of gray the night before, a third coat first thing (although I have to admit my first thing is later than yours :lol: ) and then clear ASAP.

One last note about humidity

I am a HUGE fan of having a humidity meter in the area where the application is being done. We have them and you can get them off amazon for about $20. The nicer ones show you max and min as well.

I'll try to respond to everything you mentioned....

Yea I saw on your site that you suggested 1 pound of flake per 100 sq. I was about 1.25 lbs per 100 square and I agree that alittle less would of probably been better.

My 24 T8 bulbs probably bleached out the ability to see applying the clear. with the light off and just using the sunlight it was very easy to see.

Umm... the constancy seems thiner than the gray, atleast when pouring it into the pan. Maybe I'm wrong.

I honestly cant comment on what the floor would look like if I just had 3 coats without chips and allowed it to dry. From what it looked like wet before throwing the chips I'm not 100% certain it wouldn't of had any roller marks at all. A 4th coat with the grind would of helped because each coat looked better than the last.

The price I mentioned included product, 3 gallons of gray, 1 quart of gray, Rollers, 1 Gallon of clear, 1 quart of clear, cheap paint brushes to throw away after each coat, small 3" roller for the side walls, and including the $110 price for a 4 hour rental of the grinder.

As for it being a 3 day project:
Day 1, 3 hours of grinding and prepping the floor
Day 2, 2 Hours of application of coat 1 and taping
Day 3, about 5 hours involved for coats 2,3,4 and vacuuming/leaf blowing

About 10 hours involved total for two people on a 400 square foot garage. It had to be spaced out over 3 days due to the floor drying and the time between coats.

As far as coverage:

Coat 1: 1 gallon and a full quart for my grinded 400 square floor
Coat 2: Alittle less than a Gallon (I poured the left over into the next gallon to be used)
Coat 3: Alittle less than a Gallon (I had maybe half a quart total left of the 3 gallons and a quart)
Coat 4: (The Clear) I used every bit of the 1 gallon and 1 quart I had

This is a great post and great information. Thank you!

My experience in many respects was similar to yours. My concrete was in a bit better condition so I did not grind the floor. Cleaned it very well and used the etching degreaser that was supplied by Justin (that stuff worked great!).

After two coats of the silver, there were still a fair amount of roller marks and if I had stopped there I would not have been happy. I bought the rollers, etc. from Justin, and I frankly don't know what I could have done differently to avoid roller marks after two coats. Fortunately, the plan was to put on two coats of color after the two silver ones, which I did. The first coat of color (the third coat overall) went on without leaving ANY roller marks visible. The floor looked great upon applying the color coat. Could have easily skipped the fourth coat, but for the desire to add more thickness for durability.

I also had the same issue you had with trying to apply four coats within the re-coat window. Very hard to complete them all within the window given, particularly if you don't have help the whole time (and there aren't many friends willing to stay around late at night and then wake up at 2 in the morning to help you apply it).

That said, while mine has only been down for a bit over a month, the end result seems to be durable and it looks great. Time will tell on durability, but if it passes that test, it's a great product.

Yea seems like we had similar results! after the roller marks in the first coat I made my dad roll the second. In the second coat I had a few roller marks present but not nearly anything like the first coat. Although I agree with you I wouldn't of been happy with the soiid gray floor after two coats. I read the replies here and made my dad watch the 4 min video on Justin's website that shows how to apply it.

Honestly when it says to work in 4x4 sections I was working in 2x2 sections and reloading my roller and blending back into the previous section. If I worked in 4x4 sections it would of had even more roller marks. My dad said, "I've been painting for 30+ years, I think I know how to roll. Haha he was getting mad I was critiquing him. Lol

But once the flakes got thrown in my third coat everything look perfect and uniform. The flakes hid any roller marks that looked present in the wet paint before throwing the flake. I can't really comment on what it looks like after 3 coats of gray and it dries.
