Yes, marble countertops are fairly soft and can scratch easily, especially compared to rival materials. However, most marble scratches are easy to repair, thanks to marble polish and repair kits. Deep scratches will require a professional.

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.

Epoxy is typically more affordable than granite, especially if you’re choosing a high-end slab. Most granite countertops cost $75 to $145 per square foot to install, with high-end varieties topping $185 per square foot. 

In contrast, epoxy countertops cost $50 to $150 per square foot to install. The material costs for epoxy are significantly lower than granite, but installation costs can be higher. Rather than simply cutting granite countertops to size before installation, your contractor will need to carefully pour the epoxy over an existing surface.

Yes, countertop refinishing really works. It can help give your countertops a new and fresh look and extend their life by up to a decade. Countertop refinishing is a possible DIY project, or you can hire a pro if you prefer not to do it yourself.
