broke ground for new shop

Maybe the farmer was cold natured.....I think you're gonna like it...

Yep thats pretty rough...

I don't even go out there because of the floor. Just brings me down to much. Don't want to see it

Does your guy own a grinder?

No. My worry doing it myself is how do you keep a flat level area. When the grinder hits an area previously ground what's stops it from lowering that area and leaving the floor wavy

You don't want a shop floor that's too smooth. First time damp wether makes some condensation pop up on the floor & your slipping all over the place & busting your ass.

True. If I paint it I will put a anti slip on it. Just can't stand the bumpy crap on it now.

Wouldn't want to roll a creeper across it now

from what I can see in the pictures, its not worth the time grinding if its just a very small area.

It has areas like that all over. Some bigger some smaller. I'm too picky I know. Paid good money though. It looks like crap. It was supposed to be basement quality. My show room.

Double post

Hey Dave my son does concrete for a living check this out http://nickdancerconcrete.com/

Dave, it sucks that your floor came out so bad, I'll throw in my 2 cents. To have someone grind it "level" would probably cost as much as the floor was to pour. If doing it yourself the way to keep from digging or over grinding is to keep the grinder moving and watch carefully what you are doing. Basically you are evening up the rough spots. Be forewarned that there will be A Lot of dust!!!!!! Also you will have to seal the floor after grinding even if you are going to paint it because the paint will not stick to the floor after grinding. Sealer then paint. Concrete dust is so fine it will get Everywhere so make sure everything is out of the place before any grinding is done. Try this if you want take a small hand grinder (4") with a grinding disc and just try a small out of the way spot and see what it takes to even it out. As another option they offer large garage mats and the plastic tiles, maybe just in the main areas??

Not bad advice...I use cheap low pile carpet everywhere except the lift area...Looks good and super easy to replace ...We have a big fairgrounds here and I work a lot of side jobs there...I catch em throwing good/new stuff away and grab it off the fork lift !

I thought you were supposed to grind prep for paint. Maybe I'll just use that clear epoxy sealer. If I have got to seal it anyway

Dave if you seal it make sure you use the good stuff.Like i said i used some stuff i bought at Graingers that peals off the floor after the car has been parked on it...It sticks to the tires! I thought i was using the good stuff but obviously not.

Grind job is $1250. If I use sealer. I will have the cobble stone look. If I grind and then acid etch. Can I paint then

I think thats the next step...there is a lot of info on youtube to look at.

Been watching alot of those. YouTube rocks. Think rental is a couple hundred a week. Have it done professionally is 1250. Sealer is 1500. I'm not paying for the grind job. Cement guy is. Just tired of waiting for him to get money. If grind guy could do it now. That would be great.

It'll get done...how u feelin?

Had to run to town earlier. About 5 miles. Laying down now. Feel like I've been drinking. I use to spend money to feel like this.

Dave do not use clear EPOXY sealer on your freshly ground floor!!! If you are going to paint it use a sealer supplied or recommended with the floor paint or go to a concrete supplier and tell them what you are doing to get the right product. If you use epoxy sealer on the freshly ground floor it will peel off. Acid etching is a great idea but... the main problem with that is getting the concrete acid free before painting/sealing it if not done properly it can make the paint not stick. It can be done for sure but it takes more than just a simple hosing off with water. I guess it must be pretty rough if they are going down to the aggregate. Usually there will be a layer of "cream" that comes to the top that gets finished if they grind through that you will see the stone.

I will look for a different paint supplier. Everyone said no seal before paint. Paint needs some texture to bite. Thank you for the heads up. Assume from everything I read any grinding exposed aggregate. I don't like aggregate get look. Wish I could just get a whole new pour. About 15 grand or so though. Any paint suppliers you recommend. I've been staying away from the box stores. Most of info so far is come from garage journal.com. thank you again for your help

Yep..I have built two shops and didnt seek professional help on the sealer..I highly recommend it...Both of my floors peeled.
