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.

In most cases, a professional countertop installer will take between three and six hours to install your granite countertops. However, it may take two and four weeks to order and receive the materials to install, including time for measurements, checking that your cabinets can support the added weight, and delivery. If you choose a high-end slab of granite from a particular excavation site, you could wait for several months for delivery.

Since knowing how to install countertops correctly requires in-depth knowledge and understanding of the topic, we recommend hiring a professional countertops installer near you to work on this project. Kitchen countertops are a high-visibility investment, meaning mistakes made during DIY installation will be easy to spot, may cause damage, and potentially require re-purchasing materials. Professional countertop installers have the skills, tools, and experience to place your new kitchen feature safely and correctly.

Onyx countertops are naturally porous, absorbing liquids and staining easily without proper care. Regular sealing every 6 to 12 months is essential to keep them looking their best. Daily maintenance includes wiping up spills immediately and avoiding harsh cleaners or acidic substances that can etch the surface.
