Stone is a porous material used to manufacture countertops, flooring and tabletops. The material is extremely heavy and offers an unmatched level of durability. Common types of stone used for tabletops are granite, marble and quartz. Manufacturers cut the stone to various shapes and sizes. Installing a custom edge, such as a bull nose, around the top completes the fabrication. Attaching or repairing a stone table top to a table base is an easy home improvement project that you can complete in less than an hour.
Spread out a drop cloth or other protective material such as cardboard on the floor. Position the stone table top face down on the drop cloth.
Cut off the tip of the silicone tube to allow for a 1/4-inch opening in the tip and load it into the caulk gun.
Wipe the top of the table base and the area of the stone table top that you will attach to the base with a rag and acetone to remove any dirt, debris or film. This helps to ensure a tight bond when joining the two materials together.
Sit the table base on the stone tabletop and use a tape measure to center the base in the correct position. Draw an outline of the table base on the bottom of the tabletop with a pencil.
Apply a generous amount of silicone inside the outline on the table top. Firmly press the table base into the silicone. Use the outline as a guide to position the table base in its correct position. Remove any excess silicone that might squeeze out of the joints with a rag. Inspect the joint between the two pieces for any voids and apply more silicone if necessary. Allow the silicone to cure for 24 hours before moving the table.
