Sealant is your deck’s first line of defense against all major sources of damage. A quality sealant will keep out a wide variety of threats, including:

  • Dirt - Not only does dirt affect the appearance of your deck, but it can also compromise its structure. As soil particles become ingrained in the wood, they begin to grind into it, wearing down the surface and requiring you to replace the boards frequently. Sealant leaves no space for dirt to get into the deck.
  • Water - Whether from rain or from moisture in the air, water damages your deck both directly and indirectly. Directly, it causes parts of the wood to expand and break off from the rest; indirectly, it nourishes mold, insects, bacteria and other sources of decay. Sealant makes the surface impenetrable by water.
  • Mold - If mold spores manage to take root in your deck, they eat away at the wood until it is too weak to support you. With proper sealing, however, there will be nowhere for mold to grow.

The Benefits of Pressure Washing Your Deck

As effective as annual sealant treatments are, dirt, water and mold can gradually wear it down, eventually getting into the interior and weakening the wood. To keep this problem minimal, consider ordering periodic power washing to rinse these threats away. By cleaning your deck on a regular basis, you reduce stress on the sealant, increasing the chance that it will last for the long haul.
