Materials:
5/8" or 3/4" mdf (medium density fiberboard) to cover floor
gray latex paint
saw
construction adhesive
grinder or sander
polyurethane
craft sticks
grout
stamp or stencil
black spray paint
Tips:
- Cut the mdf into any size or shape to fit the floor. These instructions feature 15-inch squares.
- Applying mdf over vinyl or other flooring is not recommended.
Steps:
- Cut the mdf using a circular or table saw. Since this product comes in slightly larger than 4' x 8' sheets, one sheet yields about 18 squares.
- Use a grinder or sander to round and rough up the edges for a faux stone look.
- Mix gray paint with an equal amount of water for a wash. Use a rag or sponge to apply this using a hit and miss pounce method. Try to achieve the look of irregular stone. Apply as much or as little as desired and allow to dry.
- Spritz the squares with black spray paint. Use a light touch to avoid big splotches--just add some light shading (figure A).
- Give each square two coats of polyurethane, allowing the first coat to dry before applying the second.
- Make sure the sub floor is in good condition. Use construction adhesive to attach each stone to the floor in a desired pattern. Use craft sticks to ensure even spacing between each.
- Once the adhesive is set, apply grout to the seams following the manufacturer's instructions (figure B).
- Apply a stencil or stamped decoration (optional).
- Apply at least two more coats of polyurethane, allowing adequate drying time between coats before using the floor.
