21'x22' Legacy Industrial epoxy/urethane

[duffman04]

The time has finally come to get the garage floor done. I went with Legacy Industrial epoxy primer/epoxy base/ HD322 Polyurethane top coat with color added. Color is off-white and no flake.

I filled the cracks with rustoleum concrete patch and repair. Its a 2-part epoxy that you mix like bondo. I was worried because I had read online that people had a hard time sanding it afterwards. Its really not bad at all and sands down easily, just like bondo if you've ever worked with it. I used about 2/3's of the kit but went a little heavy on some areas after I realized how easily it sands. The diamabrush should take care of it.

Today I got the concrete degreased and scrubbed. I won't be able to do the diamabrush till sunday and then hopefully get the primer/epoxy done on tuesday, and the urethane down on weds.

Any suggestions as I move forward??

Attachments show the cracks after first coat of filler.

Alright. So I Diamabrushed (brand new brush) the whole surface for a little over 3hrs. Surprisingly it didn't create as much dust as I expected. Afterwards that got me worried. I had heard it should feel like sand paper, which mine did not... So I emailed Scotty/Louis and they're fairly certain that its been heavily troweled, creating a very dense surface. So unfortunately now I am going to muriatic acid etch it as well, sadly the edco grinder is just not going to happen this time. Bit of a pain in the a** and its going to set me back 4-5 days waiting for this concrete to dry afterwards. Etch is going down in the next couple hours.

I attached some before and after pictures for your entertainment.

Alright! Everything is done. In the end I am glad I etched in addition to diamabrushing. In my particular case, it really opened up the pores of the concrete and made a noticeable difference. That was suggested by Scotty!

I waited 3 days for the concrete to dry in about 90 degree heat and the garage door open each day. Did a moisture test because it looked completely dry and I was good to go. Urethanes (HD322) been down a little less than 36hrs now. I did each coat about 10-12hrs after the last and it worked out great.

As a heads up for others. The epoxy cleans up really well with xylene and I never had issues removing it from anything. But WOW that urethane sticks to everything! Pure xylene if anything just made it a little softer but hardly made a dent it in when cleaning tools, and my hands...

Doing it again I'd:
- Get an 18" roller instead of the 9". It'll go much quicker and you'll notice some of the roller marks less.
- Make sure you wear gloves, esp for the urethane because even xylene barely makes a dent.
- Try to do the coats in the mornings and evenings to avoid the heat.
- If you can afford it I think an additional clear coat would have given more depth. Don't get me wrong the floor is VERY shiny right now.
- Put down some plastic at the top of your driveway as a working area. I was able to clean the couple drops up with xylene and a wire brush but it would have been less of a headache.

Floor looks awesome though and I can't imagine it coming out much better. I notice little things but I think thats just cause I am paying closer attention than anyone else. The fine anti-skid gives just the right amount of traction from what I can tell so far. I'll post more photos once I get everything moved in over the next couple days.

Floor looks nice! Did you mix the antiskid into the epoxy, or into the urethane?

Looks tight! Great job.
Send me a PM with shirt size and last name sir!

Thanks guys!

I put it into the urethane top coat. I was only mixing 1 gallon (+ activator if that matters) of urethane as a top coat so I used half the bottle, about 4oz's. If you look closely at the picture with the garage door closed you can see almost a granular appearance to the shine on the floor, thats the anti-skid. If it wasn't there it would honestly be like a mirror, but I'd likely break a hip if it was wet too...
