Granite Countertops—The Resin Process



It is no secret that granite is the most popular choice when it comes to countertops. That’s because granite is beautiful, durable and affordable for many consumers. It also comes in hundreds of different colors provided by Mother Nature. In fact, over the years, there has been a large increase in the amount of colors available. This is partly due to newer technologies used in the extracting process, as well as the development of a resining process for slabs.

So what exactly is a resining process you may ask? Well let me explain. Resining involves the applying of epoxy resins to honed and dry slabs, which help fill in tiny surface pitting, or fissures that naturally occur in the stone. Once the resin is applied, the slabs are cured by going through large heated ovens. They are then sent through polishing lines, where they are polished and prepared for shipment to suppliers, etc.

The resining process allows slabs that once may have been rejected for being too brittle, or fragile to be much more safe and sturdy for shipping to be available now for consumers. Today there are way more color choices available than there was 10-20 years ago. This is great for consumers who like variety and a lot of choices.

What Is Granite Pitting?



From time to time, we are asked the question, “Why don’t some granite’s feel as smooth to the touch as others?”  That is a good question and does require a bit of explaining. Granite is one of the hardest materials available today for countertops and is composed of a variety of different minerals including: quartz, feldspar, biotite, titanium oxides, as well as some other mineral combinations, depending on the color variety. Each individual mineral, in turn, has its own hardness factor, as well. All true granite’s contain biotite, which is a soft and flaky mineral and often times, the first few layers of the mineral are removed during the polishing process, which actually creates pits in the stone. These pits are common in all granite’s and occur naturally, although some granite’s contain more pitting than others, depending, of course, on the amount of biotite, or mica throughout the slab.

While pits are common in all granite’s, it does not make the stone inferior. Over the years, pitting actually has become less noticeable for consumers, as resin-impregnated slabs became available a number of years ago. Resining is an automated process used by many suppliers to help fill pits, cracks, or fissures and involves applying a resin over a sawn slab and the application of heat. Once the resin is dry, the slab is then polished. The process removes most of the resin, yet fills areas where more prominent voids were present.

What Are Resined Slabs?



When it comes to granite countertops, there are literally hundreds of color choices. This however, has not always been the case. Over the years, there have been advances in quarrying practices, and equipment that have allowed more colors to become available for the countertop market. There have also been advances in some fabricating  processes that have also helped, including the process of resining slabs. Some of you may not be familiar with the term, resining, so I will provide you with a definition.

The MIA, Marble Institute of America, in its Glossary of Terms, defines resined slabs as, ” Slabs that have been treated with a cosmetic improvement process prior to polishing, in which a resinous adhesive, usually epoxy, is applied to the face of the slab, filling various voids in the stone surface. The resin is cured at elevated temperature, after which it is polished, allowing the resin to remain in the voids. This produces a more cosmetically attractive surface without the interruptions of the natural defects.” In other words, resining helps to fill in tiny surface pitting and fissures that occur naturally in stones.

The resining process has become standard with a variety of stones, over the last 10 years and is now common place. Slabs that may once have been rejected for being too brittle, or broke in shipping, are now available to the public increasing the number of color choices.
