As winter approaches, protecting your outdoor spaces from freezing temperatures, snow, and ice becomes essential. Concrete and stone patios are especially vulnerable to moisture infiltration and freeze-thaw damage. Sealing these surfaces before winter can prevent cracking, flaking, and costly repairs. Here’s how to get it done effectively.
Clean the Surface Thoroughly
Start by removing all dirt, debris, moss, and stains from the patio surface. Use a power washer or stiff brush along with a patio-safe cleaner. A clean surface ensures the sealant adheres properly and lasts longer through the winter season.
Repair Any Cracks or Gaps
Inspect your patio for cracks, holes, or loose stones. These imperfections should be filled with the appropriate concrete or stone filler and allowed to dry completely. Addressing damage before sealing ensures a smoother finish and prevents water from seeping in and freezing.
Choose the Right Sealant
Select a sealant that’s specifically designed for exterior use on concrete or stone. For winter durability, choose a penetrating sealer that resists salt, moisture, and freeze-thaw cycles. Read the product label carefully to ensure compatibility with your patio material.
Apply in Optimal Conditions
Apply the sealant on a dry day when temperatures are between 50–80°F. Use a roller or sprayer for even coverage, and apply a second coat if recommended. Allow the sealant to cure fully before exposing the surface to moisture.
Maintain Annually
To keep your patio protected year after year, reapply the sealant annually or as recommended. Regular maintenance will extend the life of your outdoor surface and keep it looking its best through every season.
Sealing your concrete and stone patio before winter isn’t just preventative—it’s essential. By cleaning thoroughly, repairing damage, and using the right sealant under proper conditions, you protect your patio from harsh weather and costly deterioration. A well-sealed surface resists moisture, salt, and freeze-thaw damage, keeping your outdoor space safe, attractive, and durable year after year.
