Concrete Flooring Repair

[Lonewolf]

Ripped up the carpets in my newly purchased flat, which was built around the 2nd world war.

When the flats were modernised back in the 80's the builders laid down down bitumen then 12"x12" vynyl tiles on top to cover the imperfections in the concrete subfloor.

With ripping up the carpets and the carpets grippers, the floor tiles have lited too. I have managed to reattach some of the tiles but I have a problem area, which is about 2 feet x 2 feet. The bitumen that's about a couple of mm thick has blown and I have had to lift it and remove.

Now without having to go out and buy a large bucket of tile adhesive what would be the best way of laying down a new top coat on the concrete in order to replace the tiles? Going to be laying laminate over the top/vynyl, damaged area is in a doorway between hall and bathroom.

Leveling compound is the best option.

You buy it in powder form & add water, you can get for different thickness of floors, your looking for 3-15mm
Just mix & pour, trowel it out, & it will finds it's own level, usually walk on it in about 3 hours.

You might need to prime the area with some pva mixed with water to stop the floor being too porous.
Can't see any small bags in Wickes,only 25kg bags which is too much.

I have used a lot of this in the past.

If its anything like Cement or Plaster a 5Kg bag will only be around fifty pence less.

It's a lot for a small area although other rooms could be similar... What would happen if used on a an area which is shallower than 3mm.

would levelling compound adhere to bitumen?

what floor are you wanting to lay? if laminate the underlay would takeup any unevenness

Laminate in the hallway and vinyl in the bathroom, the damaged area is in a doorway of the two.

Notwithstanding Nightglows recommendation I've leveled floors and walls with tile adhesive, sets rock hard and cheap especially if you have a load left over.

Trowel it out then use a wet trowel to smooth over, possibly with a spot of washing up liquid in the water.
