Cultured Stone Fireplace Projects

Considerations

• Check with a code enforcement inspector in the building code department to find out what the requirements are for fireplace installation. The regulations differ from area to area and are a critical element you must consider in the overall scheme of the project.

  There are a multitude of cultured stone products available in colors and textures for virtually any type of look for fireplace projects, including traditional, rugged and contemporary. Choose from many options for designing your cultured stone fireplace. You may opt to mount stone around small areas of the fireplace mantle, such as the mantel facing and along the legs or columns. Some people position the fireplace in the middle of a wall and cover the entire wall with stone. Visit a fireplace design center, or go to some Internet sites to generate ideas about your project before you set out to purchase the material.

Installation Tips

• The typical cultured stone fireplace is a zero-clearance fireplace that is comprised of a stainless-steel pipe that is framed in by 2-inch by 4-inch boards or metal studs. Use cement board or plywood to sheath the framing. Fasten metal lathe to the surface of the board so that the mortar can properly bond to the surface. Apply the cultured stone after the scratch coat is dry.

  When estimating the amount of materials, don't forget to subtract the area of the windows and doors from the total material calculations. Speak to the vendor and building code inspector about the requirements for a water-resistant barrier. Usually, this barrier is not a requirement for concrete or masonry walls.

  Lay the stone out to display the multitude of sizes, shapes and colors. Use a blend of smooth and textured stones, small and large stones and light and dark colors to create variety and distinction in the design. Choose a mortar color that accentuates the appearance of the cultured stone fireplace. For example, tan mortar enhances earth-tone cultured stones. Do not make the mortar too thick or thin. A sour-cream like consistency works best.

  Make sure that the mixture is free of small stones. Use a small whisk broom to obtain a smoother joint surface and fill pockets and cavities in the mortar joints. Avoid mortar on the stone surface because it stains the stone and is difficult to clean once it is dry.
