Linoleum over previously painted concrete

[Innov8tive1]

Not a garage project but I do need some advice on my laundry room floor.
There are currently 2 coats of very loosely adhered paint on it, much of it has flaked off and the rest probably wouldn't take too much to remove.
What would be the best method to remove the remainder of the paint and prep the floor for the installation of linoleum (as per my wife's request)?
There is a bit of efflorescence in some places.

Hey Innov8 from North Eastern Ontario.

How big is the laundry room? Good wire brush can clean up a lot of paint but if the room is too big then it would be a job. I find that in the basement you get some efflorecence and a hand size wire brush does the trick.

I have not yet measured it but it is probably 8'x16' or so, it also houses our furnace, water treatment system (we're in the country on a well), sump pit and HRV unit. It would take a while with a wire brush. Much of it has already peeled off but some areas seem to have adhered better.
I'm thinking maybe a large wire wheel on an angle grinder, messy but it would get the job done.

If I were you I would just screw down some 1/4" plywood on top of the old stuff and lay your linoleum on top of that. For an 8x16 room you would only need 4 sheets. Would save you alot of time over stripping all that old paint off and also provide a nice surface for the glue to stick to.

I would think some of the pergo type flooring would be ideal here, you would not have to do any prep to the floor, just snap and lock in place. That size room would go quick.

Snap flooring might not be the best as the floor might get wet from time to time.
I should probably also mention that this is temporary, how temporary I'm not sure but at some point we are going to gut the entire room (probably when the furnace gets replaced and it's almost 20 years old) and insulate it properly, re-plumb and clean it all up and do something different with the floor at that time. But for now we just want to have a surface that is easier to clean than peeling concrete.

If you have peeling paint, most likely you've got moisture coming through the floor. If you have efflorescence, most likely you've got moisture coming through the floor.

Clean a small patch say 6x6 out of the traffic lane, tape a piece of clear visqueen over it and wait a few days to see if there's any moisture collects under the plastic sheeting. You'll have to deal with the moisture issue before doing anything permanent, if there is a moisture issue.

Good idea, I will try that and see what happens. BTW, I measured and it's 11'x20'......I can't estimate very well I guess. Probably because of all the equipment in the room.

Well we were at the home improvement store yesterday and the wife pulled the trigger and bought some linoleum. I taped a piece of plastic to the floor and we'll see in a couple of days if we have any moisture or not.
Now the lino. can either be "loose layed" or glued down. So I think what I will do is loose lay it but glue down just the edges, that way when we go to re-do the laundry room I can possibly salvage and re-use it or at least a portion of it. That way I won't have the corners folding and dirt/moisture getting underneath it. Good idea? Bad idea?
