Floor levelling

[Marcr2712]

Hi All,

I have removed some tiles from the floor and intend to use some levelling compound before the floor is laid. Some of the adhesive has come up with the tiles and some has stayed down. Will it be ok to use compound over this or will it all need scraping off?

Thanks

You need to remove all the loose sections. With a SDS drill if needed or use a hand grinder.
