How To Professionally Seal Your Granite Countertop

One of the best reasons for choosing a granite countertop is its durability. Unlike many surfaces, a granite countertop resists heat, chipping, and scratching, making it well suited for active households and frequent cooking. It is a natural stone that delivers long-term performance without feeling delicate or high maintenance.

Because it is a natural stone, it does require periodic sealing to maintain its protective qualities. Proper sealing helps a it resist moisture, stains, and everyday spills while extending its lifespan. This guide explains how to care for your granite countertop so it stays beautiful for years.

How Often to Seal a Countertop

The sealing schedule depends on the density of the granite slabs used. Some granite slabs are naturally denser and absorb less moisture, while others may be more porous. Lighter surfaces may need sealing more often since stains show more easily on a granite countertop.

A simple water test can help determine when sealing is needed. If water soaks in quickly, your granite countertop may need multiple coats each year. If absorption is slow, fewer coats are needed to protect the surface of your granite countertop. Regular testing ensures your granite countertop remains protected over time.

Sealer Is a Great DIY Project

Many homeowners choose to seal granite slabs themselves rather than hiring a professional. Sealing granite slabs is affordable, approachable, and achievable with the right products and preparation.

Start by selecting an impregnating sealer designed to penetrate the stone rather than coat the surface. Clean thoroughly and allow the surface to dry completely before application. When applying sealer to granite slabs, work evenly across the surface without allowing the product to pool. Apply a second coat after the first has set, then allow proper curing time. These steps protect granite slabs while preserving their natural appearance.
