Abstract
A two-pack cementitious composition consisting of iii) an alkaline component comprising gypsum, an alkaline polymer, water and a hydration inhibitor, which is stable in a fluid state and which can be set and hardened upon the addition of an hydration activator, and iv) an acidic component comprising an acid soluble hydration activator, is suitable for forming a self-levelling floor composition. The self-levelling floor composition may be used in a method of levelling a floor.

A method of levelling a floor, which method comprises:
- a) mixing together the two components of a two-pack cementitious composition consisting of:
- i) an alkaline component comprising gypsum, an alkaline aqueous polymer emulsion, and a hydration inhibitor, which is stable in a fluid state and which can be set and hardened upon the addition of an hydration activator, and
- ii) an acidic component comprising an acid soluble hydration activator, to form a self-levelling floor composition,
- b) applying an amount of the two-pack cementitious composition to the floor in an amount sufficient to level the floor, and
- c) allowing the self-levelling floor composition to harden and dry.
