The angle at which you cut countertops depends on the material, your intended outcome, and the location of the cut. For example, rather than cutting a straight 90-degree angle for internal corners, cut edges at a 45-degree angle to give a clean, professional look. For outside edges, most homeowners want squared-off sides, so 90-degree angles can make the most sense there. Because you want to get angles exactly right to minimize seams and eliminate the need for patching, be sure to measure several times before cutting and use the right equipment to get sharp, accurate angles.

You can cut countertops without chipping by using your saw correctly and having a new fine-toothed blade. You can also put masking tape on the front of the countertop material across the cut line and cut from front to back. However, it is very hard to cut countertops without chipping them, especially if they are made of stone or more fragile materials like laminate. The best advice is to know how to use the equipment, use the correct cutting method for the material, cut from back to front, move slowly, and practice on scrap material first.

Concrete countertops require regular upkeep to maintain their appearance and durability, and are generally considered harder to maintain than other materials. For daily cleaning, use a mild, pH-neutral cleaner and avoid harsh, acidic products that can damage the sealant. It is crucial to wipe up spills immediately, especially from acidic substances, as concrete stains easily. To protect against stains and moisture, the countertops must be resealed periodically—at least once a year, if not more frequently. Additionally, use a cutting board to avoid scratching the surface. Be aware that concrete is also prone to cracking over time, which may require repairs.

Yes, Corian® and other solid surface materials can be cut with standard woodworking tools, such as a circular saw or a jigsaw. However, it is crucial to use the correct type of blade to avoid damaging the material.

For a circular saw, a tungsten carbide-tipped blade is required; a triple chip grind blade is highly recommended. For a jigsaw, you should use a fine-tooth down-cutting blade. Do not use blades designed for cutting wood, as they can cause microfractures that weaken the edges of the countertop. A diamond blade is also unnecessary, as those are designed for harder materials like natural stone, which Corian is not.

After cutting, the edge will be rough. It is essential to sand and smooth the cut edge to prevent microfractures, which can eventually compromise the integrity of the countertop.
