While the beauty of granite derives from its individuality, granite’s character and appeal extend far beyond aesthetics. With many different types of granite currently available, the most common homeowner interest lies in performance; how well does it resist staining, scratching and etching?
However, when purchasing any type of granite for your home remodel, it is important to understand what epoxy resin treatment is, and how it relates to durability and performance.
Granite Countertop Olive MIllNatural, organic stone such as granite comes in a wide variety of colors, shapes and textures. Unfortunately, many slabs have natural defects such as fractures, pitting and superficial surface holes. While polyester resins have been used to fill and reinforce travertine and other types of marble for over 50 years, the application of epoxy resin on granite is a more recent technology.
Other than the ability to salvage as many slabs as possible, according to Stone World, there are other reasons why epoxy resin is applied for granite enhancement and repair, including:
Natural micro-fissures in many different kinds of granites reduce the beauty of the material by compromising the final polished effect.
Fissures (cracks) passing through the granite slabs decrease the slab strength, and pose a hazard under some applications, such as outside paneling.
What are the benefits?
Epoxy resin is effective at running into minute cracks and filling any pitting or micro-fissures present in the granite. The extremely high bonding strength repairs structural defects, resulting in a strong slab with a durable finish. This very durable and extremely elastic adhesive conforms to the thermal expansion of the stone, enabling it to sustain the wide array of temperatures typical in indoor and outdoor use.
Safety and durability
One concern many homeowners have is epoxy resin treated granite’s durability and safety as a material for kitchen countertops – will the finish sustain damage if a homeowner places hot items on the surface? Because granite treated with epoxy resin must comply with the latest FDA rules for food contact, the material is safe for kitchen use. While epoxy tends to soften in the presence of high temperatures, small fractures are not affected by heat application, and visible epoxy glue will return to its original state when normal temperatures resume.
This recent epoxy resin bonding technology improves the qualities of natural granite, ensuring that beautiful stone is now available on a larger scale at an affordable cost, and virtually free of defects.
