Managed to get an old metal cabinet today for paints & oils etc. Don't want to burn the garage down when I start using the new welder. Anyway that led to me spending the day completey rearranging the garage.
I'd like to tidy the floor up a bit. The concrete has got some big craters in it in places. Has anyone got any recommendations for something to fill / smooth out the floor. Also would like to limit the damp that comes up through the floor a bit. There's no wet patches but there's no DPC either. Would a floor paint be of any use in this? Also how long does floor paint take to go off in this weather ? Any brand recommendations, Epoxy or Polyurethane ? All opinions welcome

we picke up some conveyor belt from a company an put that down, it was quite cheap as well as it was used and no good for anything else

Have you got enough depth to lay a DPC and then a fresh layer of concrete?

If not then I'd go for a serious liberal layer of PVA followed by a self levelling latex screed then a layer of floor paint. You won't eliminate the rising damp, but it should slow it down a bit.

There might be some paint on DPC products available I guess...?

I just laid a 50mm slab of hand-mixed concrete on top of some PVAd old rubbish concrete (with obligatory craters) and painted it with cheap as chips screwfix paint. Job's a good'un. No dust and no craters.

The levelling of the cement was done with the mark one eyeball and my left foot Doesn't look too shabby!! Most of the time the floor's covered in shite anyway so can't see it!!!

When i owned my first house, i put levelling screed on the floor to level it off and fill the craters. It peeled up and chipped after about a month, but then i didnt seal the old stuff first.

There is a product here in Canada called DR. Crete, has an epoxy component, will set under water, and fills cracks dries in about 8 hours.

PVA is not waterproof so PVA and then another layer of something is pretty useless.

If there is enough room to raise the floor by 50mm I'd put a DPM over the existing floor and then lay a 50mm screed.

Failing that get a self leveling compound that will put up with the damp and then paint with an epoxy paint suitable for damp floors. The kind of product you will want is paint on DPM.

Discovered something called moisture cured polyurethane paint which has dampproofing properties so might try grinding the old floor smooth, put some fast setting concrete repair in the holes & then slapping a thick layer of that paint on.

You could try some of Watco Products, I have specified them in the past and have their Concrete floor paint on my floor

Floor paint

The paint has been fine although if you call their technical services dept, they will tell you it is not suitable for domestic garages

Have also used this for filling holes in warehouse floors:

Our place already had the garage floor (ceramic) tiled by the previous owner. I was a bit mithered at first, but it's fantastic when you spill stuff...like diff oil when I removed my backplate on Sunday. A pool 9" wide, mopped up and cleaned - no slippy patch or stained floor.

And they take my Indy on axle stands, ramps, trolley jack, the lot - no marks. (touching wood...)
