Handling Hints
Handle products with care to avoid damage to ornamental surfaces and fracturing of components. Avoid unnecessary contact of exposed faces of components with objects that may scratch or scuff surfaces. Carry components on edge and store in original packaging at room temperature. If any facing or hearth piece is bowed or warped following shipment, simply lay flat (face up) and mist with water using a spray bottle. Repeat if necessary after allowing time to dry. Mantel components are ideally applied to solid, stable, flat and level substrates such as plaster or drywall. Wood surfaces are typically not stable and may cause cracks in components or filled joints.

Important: Layout and dry fitting of entire mantel is recommended before any adhesive is applied.

Components may be secured using a high-strength construction adhesive. The construction adhesive should be suitable for plaster or masonry material and potentially high temperature application. Use bracing to secure components tight to the wall until the adhesive sets. Avoid adhesive on exposed component surfaces and use caution not to apply too much. Use a finishing nail or a small piece of plastic (shaped like a ‘V’) to remove excess adhesive at joints. Clean off excess adhesive immediately as required by adhesive manufacturer instructions.

Fireplace Surround Installation

STEP 1. Hearth Installation
Install the hearth first, centered on the firebox opening and set tight to the wall (Fig. 1). Set the hearth level on a bed of thin set masonry material if the floor is uneven and ensure there are no voids between the floor and underside of the hearth for complete and continuous support throughout its area, especially at the corners. Apply Construction Adhesive. (Fig. 1.1)
STEP 2. Install Mantel Legs
Install so that each mantel leg overlaps its respective facing panel. When set in place, the level height of each mantel leg must be identical to provide for a level mantel shelf. Use shims to level the mantel legs. Apply a generous and continuous bead of adhesive to ensure continuous contact between wall and bedding surface of the mantel legs. (Fig. 2) and (Fig. 2.1) Brace mantel legs securely until the adhesive sets. Note: If necessary, the mantel legs can be cut at the base to adjust the overall height of the mantel.
STEP 3. Install Mantel Shelf
Your mantel shelf should be set so that there is equal distance on the outside of each leg. After locating this position, mark with pencil. Apply adhesive to the back of the shelf as well as the top of each leg. (Fig. 3 and Fig. 3.1) Set the shelf. For additional security, install two (2) – 3″-long wood screws into the top of the mantel shelf and into the wood blocking below. Locate screw holes approx 1″ from the wall and 18″ on either side of the mantel centerline. Drill pilot holes first and countersink so that screw heads are located below the surface of the mantel shelf.
STEP 4. Screw Hole and Seam Repair
Mix a small amount of the facing powder provided with a few ounces of the white liquid to create a workable paste (peanut butter consistency). Fill screw holes and seams with a knife or small putty tool to a smooth finish. Area may be sanded lightly, after it dries, if required.
STEP 5. Sealing Your Fireplace Mantel
All Cast Stone Mantels (Polished and Honed) require a sealer as recommended by the manufacturers. Use a clean cloth and apply sealer on all components.
STEP 6. Wait To Use
After installing any of our stone mantels, wait 30 days to use your fireplace.
