Wipe down the cement bench to remove any dirt buildup or cement dust. Regardless of your choice of decorating, starting with a clean bench allows for a smooth finish.
Add a layer of decoupage on the bench. Select decorative paper, photographs or even cutout words and create a collage. Glue the elements into place with an all-in-one glue and sealer. Allow time for the glue to dry and apply a coat on top of the pictures. Repeat the process. Finish the bench by spraying on a coat of waterproof acrylic sealer.
Paint the cement bench for the simplest way to decorate the object. Use waterproof acrylic paint designed for outdoor use for a weatherproof option. Apply a single color to the bench, paint a detailed picture or create a bold pattern with multiple colors.
Add tile to the seat of the bench. Create a mosaic or apply the tiles in a uniform pattern. Use flat tiles like ceramic or glass for the most comfort. Apply a layer of mosaic cement to the surface of the seat. Press your tiles into place in the desired order. Allow time for the cement to dry. Mix up a batch of cement-based grout and use a masonry trowel to spread it between the cracks of the tiles. Wipe off the excess with a damp cloth. Let the tiled surface dry and brush off any dust left behind.
