DIY - How To Attach Metal Table Legs To A Granite Tabletop?

Granite has been used as one of the most versatile decorative materials for decades. And the trend of using granite for table tops is not too strange to many people. In comparison to wooden tops, granite has more benefits like it doesn't stain, is waterproof and has a distinct gloss that can bring a luxurious and bright look to any living space. Moreover, granite table tops are very durable and highly functional, they can stay looking fabulous for years with just a little care and maintenance. A granite dining table set can be a perfect complement for any dining space and the whole house. 


When it comes to choosing a table base or legs for heavy granite tops, we recommend bases or legs made from heavy gauge steel or stainless steel. Steel table bases or legs are fabricated in various designs to help fit your interior decor. Powder-coated in matte black, they look very modern and stylish, and very easy to clean, making them a great choice not only for indoor but also for outdoor furniture. 

How to attach metal table legs/bases to granite tops?

Working with granite or any kind of stone as a tabletop requires special tools and skills, which means it's best to avoid drilling or screwing directly into the granite top. Fortunately, there is a simple workaround that doesn't require specialized techniques to attach a granite stone top to a metal table base or legs.

To connect a granite tabletop with our metal table legs/bases, some of our customers are using Silicon glue to give support to their tabletop. Some glue manufacturers have designed silicones specifically used for granite adhesives. We recommend it would be a nice choice to use SikaBond Construction Adhesive or 2-part structural epoxy. Here are the detailed steps to adhere a granite tabletop to metal legs or bases. 

Step 1

Spread an old blanket or rug out on a flat surface, then place the granite top on the blanket. Make sure the piece of fabric is large enough for the granite top to fit on and to avoid scratches.

Step 2

It is important to clean the granite surface before applying the glue. Make sure to remove any dust or debris left on the underside of the granite. You can use water or a mixture of vinegar and water, grab a piece of cloth and get to wiping. After that, just wait for the surface to dry. 

Step 3

Determine the exact position on the underside of the top where the table legs will be attached. Mark the position where the mounting plates will be glued using either a pencil or a marker.

Step 4

Apply a thin glue adhesive to the mounting plates’ surface and glue them to the granite, centering each piece over the marks. You must spread the glue out evenly on the flat metal surfaces and place them in direct contact with the granite top. Try to avoid any single air bubble between the two surfaces during the process. Afterward, gently press down on the plates with your hands for a few minutes to avoid them from moving or falling. 

Step 5

After a few minutes, apply some more glue along the edges of the mounting plates to improve bonding strength. Place a heavy object on top of the mounting plates and let the glue dry completely. 

To avoid the glue thickening too much and to speed up the drying process, you can use a hairdryer to warm up around the mounting plates where you are applying the glue.

Here are some of our industrial glue recommendations. If you can’t buy them locally, try to obtain them from Grainger, McMaster-Carr. These types of glue are a good choice for bonding metal to granite. It works well with different types of metal.

  1. SikaBond Construction Adhesive

  2. Sikaflex Mortar Fix

  3. Sika Corporation

All three of the glues mentioned above will take hours to set. However, you must leave it to dry for a minimum of 8 hours before using it. It depends on different products but the general rule is to wait for a long time. This is important to do so that the mixture will have been dried out before you can use it.
