Pitted Floor Prep for Metallic Epoxy

[87brad]

I have a 3 car garage about 671 sqft. About 130 sqft of that the concrete is only a year old where the rest of the concrete is from the 60's. I diamond grinded the entire garage today and there are some pitted spots as seen in the pictures. A couple of the spots have much deeper pitting than the rest of the spots.

How would you recommend to fix these spots? Should I just patch the spots with quickcrete or put a self leveling compound over the whole floor? Any products you would suggest over others?

I ordered the following just a little bit ago:
Legacy Metallic Garage Coating Kit
Project Size: 750 square feet
Pigment Color # 1 (75%): P1010 Pearl ;
Pigment Color # 2 (25%): P1020 Dolphin;
Primer: Black;
PRO-VERSION: Yes, I want PRO-VERSION (+40%);

Plus:
Xtreme Polyaspartic-66
Two Gallon;

Since you are using a Legacy system, I would reach out to them specifically.

My recommendation for the small pitted areas would be 100% solids epoxy joint filler troweled on smoothly.

For the larger areas what I would normally do is prime with 100% solids epoxy and broadcast quartz aggregate to regection then trowel as smooth as you can.

Also, a cementitious epoxy mortar can be used.

Reach out to Scotty and get his rec, he'll getcha squared away.

I would use our FiveTon Concrete Repair Patch for these. Easy to use, no-shrinkage!!

BTW.. we changed you to Manatee, the floor you mentioned used Pearl and Manatee, not dolphin, sent you an email.

I did this exact coating system.

I used the FiveTon repair patch for similar spalling/pitting and it worked very well for me.

I didn't mix as much sand as suggested but instead mixed enough to create a slurry that I could spread more easily and I was able to cover the areas I needed to and was happy with the result.

Also, when you do the Polyaspartic coating you may want to consider mixing 1/2 the kit at a time. My floor was 850 sq-ft and I ended up doing two coats and had quite a bit of material left.

Good call DJ!
(1) gallon at a time on the Xtreme-66, it's a 1:1 ratio so this is very easy to accomplish.

What size kit did you use for the 5 ton?

 

[djgarrett21]

I got the large (resin only & bought quartz sand at HD). I'd guess I got at least 30 sq-ft @ 1/8" depth.

To the OP,

Looks like your vendor is taking care of you.
