The frequency for sealing granite countertops depends on several factors, including the type of sealant used, the color of the granite, and how heavily the countertops are used. As a general guideline, resealing is often recommended every 12 to 18 months, but some sources suggest it could be as often as every few months or at least once a year.

The type of sealant is a major factor: water-based sealants may need reapplication every six months to a year, while more durable solvent-based sealants can last for five to 10 years. Additionally, factors like heavy kitchen traffic, frequent use of acidic cleaners, and lighter granite colors may require more frequent sealing to prevent staining.

To determine if your countertops need resealing, you can perform a simple water test. Place a few drops of water or a wet paper towel on an inconspicuous area of the granite. After 10 to 15 minutes, check the spot. If the water has beaded up, the seal is still intact. If the water has been absorbed and darkened the stone, it's time to apply a new coat of sealant. You can choose to seal the granite yourself or hire a professional to ensure it's done correctly.

Formica® is a brand name for the laminate countertops it produces. Laminate is the generic term for a countertop material made from layers of paper topped with an image layer, all compressed under high pressure to form a solid, easy-to-maintain surface. Other brands that produce laminate countertops include WilsonArt® and Arborite®.

When comparing Formica to other laminates, the choice often comes down to personal preference. Formica is a popular brand known for its durability and affordability. Due to its brand recognition, it may be slightly more expensive than generic laminate options, but the name often carries an expectation of a certain quality standard.

Butcher block countertops typically last around 20 years, and sometimes longer, with proper maintenance. This lifespan is comparable to granite and longer than laminate. Key maintenance tasks include regular cleaning after every use and resealing, ideally once a month. You can also sand and resurface the countertops to remove imperfections like deep scratches, stains, dings, and scorch marks. The longevity is also affected by the thickness of the wood strips used in its construction; thicker strips are generally more durable.

Clean with mild detergent and water, and avoid abrasive cleaners or sharp impacts to preserve the surface.
