Finishing a concrete floor to look like marble gives the appearance of a more expensive stone, without the hassle that having marble floors entails. Concrete floors offer stability that other floors can’t, and all that is required to take care of the painted concrete floor is an occasional sweeping and mopping. Before you begin, choose several colours of paint that complement and contrast one another.
Using the paint roller, paint the entire floor with the base colour you chose. Allow the base coat to dry according to the manufacturer’s specifications.
Apply a third colour, different from the two colours in Step 4, but complementary to them, by dappling it on with a natural sponge before the paint you have already applied is dry. Dappling is achieved by dabbing small amounts of paint gently on the floor.
Allow 24 hours for the marbled effect you have achieved to dry completely.
