Slate has traditionally been used as a roofing material or as flooring for outdoor and indoor walkways and stairs. Slate plaques can also be used as decorative pieces to adorn almost any area of the home, from a welcome sign outdoors to an homage that represents a cherished pet. Painting slate properly will ensure that the paint adheres to it effectively and that the piece remains vibrant for several years to come.

Things you need

  • Soapy water

  • Kitchen sponge

  • Acrylic paint

  • Paintbrushes

  • Stencil

  • Slate sealant

Clean off the slate piece with soapy water and a kitchen sponge. This will prepare the slate to accept the paint more effectively.

Allow the slate to dry completely.

Cover the surface of the slate with a coat of acrylic paint. Acrylic will stick to the slate more effectively than water-based paint.

Allow the paint to dry before adding details to the slate plaque. Apply shapes and designs to the slate freehand or with the help of a stencil.

Allow the painted designs to dry completely. Apply a thin layer of synthetic slate sealant, which can be purchased at home improvement or hardware stores, with a paintbrush.

Apply a second coat of sealant, if desired.

Tips

  • A second coat of acrylic base paint can be applied to the surface of the slate if a single coat is not adequate.
