Winter is just around the corner, and it's time to prep your backyard for cold weather and precipitation. You’ve turned off the water, raked the leaves, and put away the summer toys. Now it’s time to close down your stone kitchen!

If your outdoor kitchen features natural stone like granite, quartzite, or marble, keep in mind that these materials are naturally porous. Without proper protection, your countertops can absorb moisture from rain, sleet, and snow, leading to stubborn stains or freeze-thaw damage when temperatures drop below freezing. A high-quality penetrating sealer is essential for any natural stone countertop, especially when exposed to the elements.

Sealing your stone creates an invisible barrier that:

• Prevents deep staining
• Reduces moisture retention
• Helps prevent surface dulling
• Limits the chance of freeze-thaw cracking

We recommend professional-grade sealers like Tenax or Dry-Treat. Since every slab of granite, quartzite, or marble is unique, feel free to ask our Capital Stone sales team in Schenectady or Saratoga Springs. We’re proud to be the premier destination for countertops in Upstate New York and are always happy to help you pick the perfect match for your specific stone.

Step-by-Step: How to Seal Your Countertop

1. Prep and Dry. Clean your stone with a pH-neutral cleaner (mild dish soap and warm water works great!). Rinse thoroughly and let it dry completely. A clear, sunny day is best for this process.

2. Apply the Sealer. Working in small, manageable sections, use a micro-fiber cloth or soft applicator to spread an even coat. Follow the manufacturer’s instructions for absorption time. If the stone absorbs the sealer immediately, apply a second coat.

3. Wipe Off Excess. Once the recommended time has passed, use a clean, dry cloth to thoroughly wipe away all excess sealer. This step is crucial—leftover product can dry into a hazy, sticky film.

4. Allow to Cure. Patience is key! Let the sealer cure for at least 24 hours (or per product instructions). Avoid using the counters or placing items on the surface during this window to ensure the protective barrier sets properly.

5. Winterize Plumbing. If your outdoor kitchen includes a sink or water line, be sure to shut off, drain, and blow out the supply lines to prevent frozen or burst pipes.

6. Cover the Surface. If your countertop lacks overhead shelter and will be exposed to direct precipitation, cover it with a breathable waterproof cover or heavy-duty tarp to keep standing snow, ice, and debris off the stone.

Taking the time to seal and cover your natural stone countertops before winter sets in is the single best way to protect your outdoor kitchen investment. Whether you have granite, marble, or quartzite, proper winterization prevents costly moisture damage and keeps your surfaces looking pristine year after year.
