Hey guys,


I am starting to work on my garage floor and just cant seem to decide what I want to do.

For whatever reason, it looks like the previous owner of my house etched the concrete but did not put down any type of coating. On top of that, it was not spread uniformly across the whole surface. This left me with a garage floor that dusts terribly.

My initial idea was to Grind the floor down to remove all the loose material and make a relatively flat uniform top across the whole surface then lay down a densifier and sealer.

However some research tells me that densifiers even with a sealer does not 100% dustproof a floor. If this is true then my other option is to use a topical coat such as a acrylic sealer or even epoxy.

After seeing the acrylic sealer on the floor of a facility I work at, I wasn't too impressed on how easy it is to scratch. They use some stuff called Vocomp-25 which is water based. I am not sure how much more superior other formulas are. I wouldn't mind applying a epoxy, especially for the protection from fluids/cleanup and how nice it looks. However never really had any experience with a top tier epoxy floor. Only a few friends home depot bought kits which were meh.

I will be doing a bit of welding and small amounts a metal work. It will also house a Mini sprint dirt race car where it will be torn down often. Other than that just your typical beer-driven weekend stuff.



I appreciate the advice.

I just used BASF Masterkure CC 250 SB on my floor. It cured the dust problem in my shop. It isn't an epoxy coating, so it will scratch and wear, but I can always re-coat it down the road. It was about $150 for a 5 gallon bucket at a local concrete supplier. See the last picture I posted on my shop thread.

If you are going to grind the concrete anyways, then you've done most the hard work required for applying a good quality coating. There are some great vendors on this forum that offer excellent, commercial quality product. I suggest giving some of them a call to get an idea about cost and options based on how you want to use your floor.

Grind the floor down and verify that the concrete is not soft once that top affected layer is removed. Check how easy it scores, etc. Moisture test and then go back with a clear polyurea, a colored coating (epoxy, polyurea or Rust Bullet) or a sealer. If you are using a sealer make sure the mil thickness is sufficient to even out the floors texture

Hi coat it with a single coat of our clear SPGX polyurea/polyaspartic and it will look
Magnificent and give 20x the performance of a sealer. Cost about 60 cents per ft.
