Best marble and granite pros near Covington, VA

You can cut food on tough, scratch-resistant granite countertops. However, these hard surfaces can quickly dull your knife blades, and continual cutting in the same spot can eventually lead to marks forming and compromising the protective sealant. As with any countertop material, it’s always best to use a chopping board.

Rubbing alcohol won’t damage most countertops, and you can mix it with water to create a disinfecting spray to keep your kitchen clean. It’s safer than using bleach on countertops, which can stain and cause discoloration. Be careful with rubbing alcohol when it comes to lacquered or varnished surfaces, though.

Yes, Corian® and other solid surface countertops can be cut with standard woodworking tools like a circular saw or a jigsaw, but using the correct blade is crucial for the best results.

The recommended blade is a tungsten carbide-tipped blade, often called a solid-surface planer or triple chip grind blade. This type of blade is hard enough to cut through the material effectively. For a jigsaw, a fine-tooth down-cutting blade should be used.

It is important to note that a diamond blade is not necessary. Diamond blades are designed for harder materials like natural stone, concrete, or brick, and Corian is not a natural stone.

Using blades designed for wood is not recommended as they can cause microfractures that weaken the countertop's edges. While a tungsten carbide blade provides a much cleaner cut, the resulting edge will still be rough and must be sanded and smoothed to prevent microfractures from developing over time.

The frequency for sealing marble countertops depends on several factors, including the quality and color of the stone, the type of sealant used, and the amount of traffic the surface receives. Marble has a porous surface that requires sealing to maintain its shine and resist scratches. As a general rule, you should seal countertops at least once a year. However, for heavily used surfaces, like those in a busy kitchen or family bathroom, you may need to reseal them every three to six months. Conversely, countertops in a rarely used guest bathroom might only need resealing every few years.
