A fireplace is a good addition to any home. During the winter, a warm fire is an economic and effective way to keep the chill out and maintain a comfortable temperature. However, using a fireplace regularly can leave its mark. Stained or damaged hearth stones can ruin the look. Replacing the hearth will instantly give your fireplace a facelift.
Wedge a crowbar between the mantel and the wall it is attached to. Gently pry the mantel away from the wall until it is released and can be lifted away from the fireplace.
Remove the hearth floor, using a demolition hammer fitted with a chisel bit. Break away the old hearth flooring until you reach the concrete base. Clear away all the pieces of old hearth and sweep the debris with a broom.
Mix thinset grout according to the manufacturer's directions. Apply a layer of grout over the cleared area of the hearth, using a trowel. Smooth the grout so it is evenly distributed.
Attach the suction cups about 2/3 inch away from either end of the slab. Ask a friend to help you lift the hearth. Lower the new slab of hearth onto the wet grout, using industrial suction cups. The hearth should be flush, with the floor around it. If the slab is resting higher than the floor, bang it down with a rubber hammer. For a low-set slab, lift it out using the industrial suction cups and add more grout. Lower the slab over the grout.
Fill any gaps between the hearth slab and the interior firebox with grout, using the trowel. The firebox is the area inside the fireplace where the wood is placed.
Wipe away any excess grout on the slab or in the firebox with a cloth.
Spread grout onto the back of the pieces of the side coverings of the hearth.
Press the side pieces of the hearth onto the facade of the fireplace. Check if the pieces are aligned.
Lay the top piece of the hearth on top of the side coverings. Apply grout on the back of the top covering with the trowel and then press the grout firmly onto the hearth. Allow the grout to dry overnight.
Nail the mantel back in place with a nail gun and finishing nails. Nail the mantle at an angle to secure it in place without damaging the surface of the mantel.
