Use your knowledge of how to sponge paint to give life to a boring concrete floor. A sponge painted concreted floor can have the appearance of granite and will add depth and color to a previously drab room.

Tips:

Check basement floors for moisture seepage. Tape a sheet of plastic to the floor, so that no air can get under the plastic. Leave overnight. If moisture is under the bag, consider other flooring options. Use smaller sponges in corners to provide consistent coverage.

    Step 1 - Choose Colors

    Choose 2 or more similar colors that will hide dirt well and match the rest of the room. Choose either the lightest or darkest color as the base coat. To create a more dramatic look that will probably hide dirt the best, start with the lightest tone and end with the darkest. To create an illusion of depth and more space, start with the darkest tone and end with the lightest. Consider one of the following combinations or play with color combinations to come up with your own.

    • Cream, tan and brown
    • light grey, dark grey and black (dabs of yellow)
    • apple green, grass green and forest green

    Step 2 - Prepare and Practice

    Clear the room of all furniture and clutter. Wash the floor thoroughly, tape the bottoms of all the walls to keep the paint off the walls. If you are having trouble deciding which color to start with, paint a practice board different backgrounds (side-by-side) and sponge on the rest of the colors to find the best fit. Adding glaze to your top coats will give them a more transluscent look. Experiment with mixing top coat paints with glaze in different ratios. Not using glaze at all with give your floor a denser, darker appearance. 

    Step 3- Roll the Base Coat

    Starting at the back of the room, roll evenly a base coat. Since you won't be able to go back without leaving footprints, make sure each section is thoroughly painted before backing up. Allow to dry for 24 hours before beginning to sponge paint.

    Step 4 - Apply Layers with Sponges

    Dampen sponges with water before use. Starting at the back of the room, dip your sponge into the paint and blot off excess paint. Apply gently to the floor, overlapping each application slightly. Try to keep a consistent pressure, but sponge painting should produce a random pattern, so you can twist your sponge in different motions to create different textures on your floor. Rinse your sponge off in water often to keep the sponge from becoming too soggy.

    Step 5 - Protect with Varnish

    To protect your newly painted floor, apply several coats of varnish once the final coat of paint has dried.
