Hey everyone. New to forum, looking for some advice. Have attached 2 car garage that I am looking to make nice/finish as parking in the Michigan winters/ little workshop to work on tractor/ sxs. Have a nice pellet furnance in the garage that heats the house and the garage. I have about a block and a half showing of concrete cinder blocks showing before turning into plywood painted/ insulated walls. The previous owner air sprayed the walls and left a ton of over spray on the blocks. So I am looking to cover the blocks to make it look nice and need and one color. I tried using a rustoleum concrete paint but the over sprayed paint showed through even after two coats. I picked up a gallon of drylock concrete paint, and applied. I liked the color and applied nicely and covered the over spray. My question is drylok okay to use just as a paint to make the block look nice? Im not concerened about waterproofing since I don't have any issues with leaks. I am sure there is moisture that leaks through. Or is there something else out there that is safer for the concrete blocks. I don't want to seal the blocks and have them crumble. I applied one coat to one section so far, but looking for a little more info on this stuff. I was thinking of doing the garage floor with something similar since it will cover old oil and rust stains on floor and is half the price of epoxy.

 

Drylok is fine for a primer over the block. Some will call it good but it should be top coated with a finish paint - most anything that tickles your fancy.

 

IMO, this is the only reasonable use of Drylok - as an actual decorative coat when finishing concrete walls.

 

Thanks for the help! Sorry reread what I typed this morning and was half asleep yet!

So I shouldn't have to worry about suffocating the cement blocks? They should be able to breathe yet? Like I said, just want it to look nice and clean, not concerned about any water leaking. Probably wont plan on painting over the drylock since I like the look of the color when dried. One coat looked pretty good, may do a second if need be. How much is too much?

Anyone use drylok on a floor? Looking to cover up the oil stains, and was planning on doing epoxy, but don't want to waste that kind of money on something the salt will eat away at or wear out.

 

Drylok shouldn't pose a problem on the interior side of the block especially if there aren't any moisture issues to start with. To paint block correctly it should always be primed with either block fill [above grade] or drylok when below grade. The biggest downside to not top coating the drylok is it will get dirty quicker than paint.

I've never used drylok on a slab. I think the drylok rated for slabs is a different coating than the one commonly used. I'm not all that fond of painting garage floors. Prep, type of coating and whether or not there is a vapor barrier under the slab all play a part as to how well it will hold up. There are detergents that may be effective on the oil stains.

 

You might want to look at some of the interlocking tiles/mats or the loose lay roll flooring for the floor. They don't depend on the floor prep like paint or epoxy do. They can be repaired if damaged or worn. They can be removed if you move or just tire of them. You can get solid colors or patterns.

Some options might look a bit expensive, but no more than a failed epoxy coating or 2.

 

Guy here told me years ago to put a little gasoline on the stain then top with floor dry, grind it in good with your foot. Worked much better than the junk I bought to remove oil stains.
