Garage Floor


Recommended Posts

So I'm finally building a new house and some how talked my wife into a 3 car garage without having to make any unreasonable promises. The garage is no mega garage or anything but, will be nice for my projects and tools. I've really been thinking about putting down an Epoxy floor to help make it look better and for the cool factor. I've done lots of reasearch on a couple of other sites about brands to use but, it seems like every product has a couple of guys that love it then a couple of guys that think it sucks. All the searching has really just made me confused.

 

Anyone have experience with these types of products? How well do they hold up to jack stands, welding splatter, and just plain working on it?

I had light grey epoxy paint in my first 4 car garage and it stood up realy well to most things I did to it (trolly jack, jack stands, engine stand etc) also brake fluid thinners, but I did have a problem in one area, after about 6 months a patch about 4' x 1' just lifted up in 1 big "flake" but I think this may have been due to the concrete still curing. (I was in a hurry to move in).

I've got www.ucoatit.com on my garage floor. I did the basecoat with flecks and the urethane topcoat. Its a 3.5 car garage and cost about $900 altoghether to do.

 

It holds up pretty well, its been almost 4 years now, but its not as perfect as they say on the website.

-The 6" or so that is on the outside of the garage door has had the urethane peel off from rain water

- I left some drag slicks laying on the floor and they left a permanent brown circle

- I let some oil and brake fluid mixed together under the car sit for a week and it left a light yellow stain (either one seperate don't stain)

- brake cleaner bubbled the urethane

- lastly, powdercoat powder that settles into a drop of brake fluid will leave a stain.

 

It seems like a lot of problems, but they are all minor and overall I like it.

I did mine with a stain and epoxy clear coat and I think it looks wonderful. I applied it almost a year ago and it is holding up well.

Over all I like it very much and would do it again but there are a few issues with it. It is not as indistructable as they claim.

 

I have several deep scratches in mine from dragging things around. I do put down thin pieces of plywood when using jack stands. No peeling though.

 

I spilled stale gas on the floor and didn't clean it up right away and it left a kind of hazzy looking spot.

 

It is very slippery when wet.

 

On the good side it is very easy to clean up. Dust sweeps off easily and I occationally mop it and it looks fantastic afterwards.

 

I also get a lot of good comments about it. I had some wood delivered to my house and put it in the garage - I thought the delivery guy would notice the Z car but all he noticed was the floor.

 

Again, I like it and would do it again, I believe there are some pictures of my garage floor in the albums.

As Pop N Wood stated, the floor prep is the key.

There are other factors to consider before purchasing one floor sealer over another: what is the vapor pressure (VP) eminating from your slab? Do you want the "finished look" or is grey concrete acceptable to you?

 

Regarding the first question, is there a vapor barrier under your slab? Do you live in a wet environment (ie, is the water table high)? If so, you may want to look into a product called Ardex, which is a ~1/4" - 1/2" slurry coat of self-levelling super hard concrete, usually guaranteed to hold up to any and all abuse you can throw at it. (Most architects in CA spec Ardex by name for remodelling large slab buildings such as grocery stores when the VP through the orignal slab is above 10-13 PSI, before laying VCT flooring)

 

Which leads to the second question: Ardex by itself is durable, but do you want to go the extra mile ($$$) and spring for an epoxy finish over it? There is also a "diamond coat" clear sealer/hardener one can buy to make the concrete EXTREMELY tough.

I did the Home Depot stuff, as previously mentioned it stains. I did white which I figured would reflect more light, and it worked GREAT. You could really see under the car pretty well. But again, it stains, so if you're really anal go for something dark. If you don't have a NEW, perfect floor than you can expect the results not to be perfect. My garage floor had an oil spot about 2' in diameter. I cleaned it as the directions stated about 10 times, then prepped as stated, and the one area where the oil spot was did peel a bit. Also it did chip in a few places when I dragged a jack over it sideways.

 

I talked to the landlord for the business I worked in at the time, and he told me they did "food grade" epoxy there, and the only way the epoxy would come off the floor there was if you chipped the concrete underneath. It was insanely tough! Also very expensive to buy, and requires a full rebreather to put down.

oh yeah, the great thing about ucoatit is it is water based, and the first coat is applied extremely thin, almost like whitewash, so it really soaks into the concrete and acts as a primer coat.

You have to make sure you prep the concrete properly. Usually means washing it with an acid solution (muriactic sp?). They usually tell you on the instructions. If the concrete is properly cleaned and porous, then even a floor enamel should hold up well.

 

Pop N Wood is on the money - Prep is everything.

 

There is already a thread on HybridZ (somewhere) on this subject. At the advice of other members, I used Sherwin Williams AmorSeal 1000. Two years later it is still holding up great.

 

Sealed concrete makes, clean up is extremely easy. The strongest cleaner I use is Windex. No permanent stains.

CODY thanks for a great post I was about to post some thing up similair but no one replies :P

I am 100 % doing this to my garage due to all the work I have done greased up the garage and it looks horrible. Besides I have done most of the dirty work and will probally not to any major swaps for a long time unless the occasional oil speals which are easy to clean in smooth epoxy floor.

 

MY question is I have concrete in my garage that has been brushed on when they put it in do I have to sand/grind that smooth? before putting the coats on. And IF I do grind and sand that I dotn have to the acid cleaning right?

You can rent a large sander from Home Depot to get rid of the brushed finish. I had the builder get mine as smooth as he could when the slab was poured. Mine still needs to be sanded some more in my opinion.

 

I think I would degrease the floor very well before sanding. It would suck to grind all the muck into the conrete and have it come out after you put the finish on.

I have a "paint chip" epoxy floor in my garage. It does scratch if you you drag something sharp across it however with all the different colors it's hard to see the scratch. As far as jack stands/the drive on lift I have, I place carpet pieces down as a precaution. It is a bit slippery when wet but cleans up great! I painted the garage and trim to match along with the cabinets. The floor is kind of hard to see in this pic but you get the idea.

I have a lift like this:

Just a big hint for you guys planning the floor painting. Make sure you clean it so well you could eat off of it and allow much more time for it to cure, especially if it is humid or cool outside. I watched my brother drive his Viper in on what should have been cured and he lifted some wide tire marks right out of the painted floor. That was not the worst part the worst was the rework of the floor (stripping the old paint, re-cleaning, re-painting, wait 2 weeks to cure, then perfect).

Good luck

I recently finished putting down the first two gallons of epoxy in my new shop.

I bought this stuff for $45/gallon from a local manufacturer of industrial finishes.

The concrete was badly stained with mud when we put the building up in the middle of winter. :bonk:

I used muratic acid to clean and etch the concrete. 1 gallon of acid mixed with 1 gallon of water

would etch about 200 sq/ft.
