All in One Floor Prep Method

[jim1504]

Hey Guys

I bought Griots paint and will soon be starting the floor prep process. Is there an all-in-one process I can use to prep the floor (such as the rental of a shot blaster)? Or, is it still necessary to degrease the floor once the floor is etched?

Thanks
Jim

That’s the beauty behind using shot blasting,, no need for any other procedures other than applying the epoxy coating.

A blaster and a good wash should take care of just about anything. You may have some oil that has seeped into the cement but it's not too likely.

Thanks guys! In reading the prior posts on this site I thought you also had to degrease. Rental of the shotblaster is $150 plus $50 for the media so it seems like the best way to go. Anyone have any tips for the use of the shotblaster?

Thanks
Jim

A steady slow forward movement works best in shot blasting. Make sure that you don’t stop in one place, it only takes a short pause to get a profound groove. The vacuum works wonders keeping the dust down. But remember to empty it often.

I also rented a large angle grinder with a diamond wheel to finish the corners and edges that the shot blaster couldn’t reach. The rental place included use of a large floor magnet. It’s the best way to pickup all the little steel beads left behind.

i agree with old car guy. in fact, i had some areas where the shotblaster dug in more than others while at a constant speed - probably due to different consistency of the concrete. So definitely avoid pausing with it engaged - dont even turn it around while engaged. I also used a diamond grinder around the edges and it worked great.

I also acid etched but that was a waste of time. the shotblaster and grinder are enough

Thanks for the tips everyone! One additonal question. Should I use a full face mask (similar to ones used with a sandblaster) or will goggles be enough. Also, is a respirator necessary?

Thanks again!

The vacuum setup that comes with the shot blasting equipment is so good that you don’t need any kind of mask at all. I would suggest that you use eye goggles to protect your eyes from any stray beads. Though I didn’t encounter any.

The diamond wheel angle grinders comes with a dust shield that isn’t as near as effective. I would suggest that you use a dust mask for that operation.

Ok so with all that is in this can just the grinder be used to prep the floor instaead of both grinding and shotblasting

You can't get into the corners with the shotblaster, hence the need for the grinder.
