How Countertops Are Glued

Answering the question, "How do you glue granite countertops together?" is one that could be answered in many ways. This is because there are so many ways that granite gets "glued". So in this portion of the article, we will take a look at three aspects of working with granite countertops in which one needs to glue the stone.

Fabricating With Granite Adhesives

Fabrication of granite countertops involves a variety of tasks in which stone glue is needed. Depending on the style of the countertop and the edges in particular, granite glue will be necessary. Even the top may need to be glued. Let's briefly look at when stone glue is needed during granite fabrication.

The first way that a fabricator uses glue on countertops that we will mention is for a process called "lamination". Laminated edges are edges that have the appearance of being thicker. This is accomplished by taking strips of granite and gluing them together one on top of another. Using this technique, fabricators are able to create elegant shapes on the edges of the countertop. You can see a variety of lamination techniques in various places online include the article: Edge Lamination Techniques for Stone Fabrication Professionals.

Installing Granite

The next aspect of fabrication that often times results in the use of granite adhesive is the installation. It may not seem like you would need to use stone adhesive for the install, but it is an important part of the process. For example, gluing the countertop onto the cabinets, bonding separate sections of the countertop requires specific stone fabrication tools and adhesive if you want to have seams that are hidden, and finally, undermount sinks have to have something to hold them against the underneath side of the countertop. Undermount sink glue is designed specifically for this purpose. So there you have three ways that glue is used for stone countertop installation.

Gluing Granite to Repair It

Long after the granite countertop is installed it may need to have an adhesive used on it. In situations where a granite countertop has been chipped or broken, granite adhesive is an essential product. Being able to restore the stone by gluing the pieces back together can save hundreds, if not thousands of dollars, since you will not need to spring for a completely new install. Using a granite glue that is completely transparent or one that is color matched to the stone yields the best results in these cases.

Choosing the correct adhesive for your project(s) then, is an important part of working with the material.
