- No you cannot use a stucco mix as a mortar bed for adjusting the uneven concrete floor. Stucco mixes don't have a lot of cement in them and they are weak mortars. You need to use a product that is designed for that application. You also need to properly prepare the substrate prior to applying the leveling mortar.
