Sealing the Deck

Stripping the Deck

To make sure the new sealant adheres to the wood properly, you will need to strip the old layer of sealant away. (If your deck has never been sealed before you can skip this step.) Stripping will be especially important if you plan to change the color of your deck.

To begin, choose a stripper that is formulated to remove the type of sealant that is currently on your deck. Some strippers are made for clear finishes and sealers, while other strippers are specially formulated to remove semi-transparent and opaque sealants.

The deck stripper should be applied according to the manufacturer’s directions. Deviating from these instructions could damage the wood on your deck.

Cleaning the Deck

After the deck has been stripped, you will want to clean the wood thoroughly in order to remove any lingering residue. Rather than preparing your own cleaning solution, pick up a container of deck cleaning solution from a hardware or building supply store. Follow the manufacturer’s instructions carefully, as any deviation could have poor results.

Sealing the Deck

There are many different types of sealants available. Sealers that fully penetrate the wood will last longest and provide the most protection. Here are the most common types of deck sealers:

• Clear
• Wood-Toned
• Semi-Transparent
• Opaque

No matter which type of deck sealer you choose, you will want to apply it carefully to ensure even coverage on the surface of your deck. If applied properly, the sealer will protect your deck for many years to come.
