1. Remove Items From The Surface
Planters that are left out all winter can cause moisture leaching, which may leave behind wood discolorations. Even if you don't expect your plants to live through the cold weather, move the planters. Heavy, bulky objects can limit your cleaning and give moisture a place to collect on your deck surface.
Store them in your garage or under your deck instead.
2. Scrub It Down
Sweep away any debris, like leaves or dust. It is important to keep your deck surface clean. Debris left to rot on your deck surface will cause deterioration. Wash the deck surface with water and mild soap or a specialized cleaning solvent.
3. Remove Mold or Mildew Buildup
Mold and mildew that might be present on the deck surface should be removed, especially because decks are a common breeding ground for them. During the winter, the moisture on your deck will attract mold and mildew, especially between tight boards or cracks.
4. Apply Water Repellant Seal
For the ultimate protection against the winter weather use a high-quality sealant that will fill cracks and coat your deck surface like a shield against moisture and ice. This might require the removal of prior finishes but the result is well worth the extra work. Come spring, your deck will look good and damage-free.
5. Remove Snow
As snow envelopes your home, it is important to remove the accumulation of snow on your house. Remember to shovel in the same direction as the boards run to avoid damaging your deck’s finish. If you use a metal snow shovel, you run the risk of scratching your deck or even removing the finish you painstakingly applied before the snow fell.
Instead, invest in a heavy-duty plastic snow shovel that can get the job done without damaging your deck.
Contrary to what you may think, do not use salt or other ice melting products on your wood surface. They may cause discoloration or damage to the finish.
These are just a few easy ways you can protect your deck during the winter.
