Pressure Treated Lumber: Because of the constant exposure to UV rays and weather, we recommend that you clean and reseal your pressure treated deck annually, paying particular attention to the horizontal surfaces like floors, rails and post caps.
UV rays penetrate wood, causing it to turn gray. Moisture brings mil- dew and algae which will stain. Heating and cooling causes expansion and contraction. Cleaning and resealing helps prevent these deteriora- tions.
Unless you want to remove the existing finish, it is best to use the same product that is currently on the deck to reseal . Read the label carefully. It will give you detailed instructions, whatever product you choose.
Trex Decking Material: While Trex is easier to maintain than pressure treated lumber, mold can grow if dirt and pollen are allowed to build up on the deck. DO NOT PRESSURE WASH. Periodic cleaning with a commercial deck wash con- taining detergent and sodium hypochlorite, (commonly known as bleach) like Cabot Deck Wash is recommended by the manufacturer. For a complete Trex Cleaning Guide go to www.trex.com.
AZEK Decking Material: To keep your AZEK Deck looking its best: Wash the deck periodically to remove grease, dirt and debris with a detergent or specially formulated deck cleaner. Rinse with a garden hose. For rust stains, use a cleaner with phosphoric acid (like a toilet bowl cleaner) and rinse. Don’t use abrasive cleaners. You can use a pressure washer set not to exceed 1400 PSI. Also, don’t use rubber backed mats. They may melt and stick to the surface.
Keep those decks looking as beautiful as the day they were built!
