If you have a deck, most likely, you want it to look its best. Keeping it clean, strong and durable will help your deck maintain an attractive appearance.

Waterproofing your deck can be a great way to protect your investment. The weatherproofing solution can be applied using a staining pad or paint roller attached to a long handle. In addition, as an alternative method of application, you can spray the waterproofing agent directly onto your deck with a paint sprayer or pressurized applicator. Still, you may have to clean your deck in preparation for the application. Here are three elements of your deck that waterproofing can improve:

The Look of Your Deck

Waterproofing keeps atmospheric moisture from damaging the wood boards of your deck so that they don't assume a dark, dirty appearance. The color of your deck wood may be bright and light-toned when you first purchase it. However, dampness that invades the wood can make the wood look darkened and worn over time. 

Even when debris, such as leaves and limbs have been allowed to accumulate on your deck during the fall, waterproofing can prevent moisture that is trapped between the debris and the deck from damaging the underlying wood.

The Strength of Your Deck

In order for your deck to be safely used, it must be able to support a large amount of weight. Moisture can penetrate deep inside your deck wood and cause it to swell and buckle. This can promote the weakening of your deck boards. As a result, your deck may not be able to withstand the weight of a falling limb or even a person.

In severe cases, moisture can cause the wood to become so softened that it can be pulled apart by hand.


If you want your deck to last, it must be adequately protected from the elements. Repeated exposure to rain, snow and humid conditions without proper protection will cause the wood to warp, soften and be more prone to damages, which can reduce the life expectancy of your deck. The barrier of the waterproofing solution helps keep your deck boards in their original condition longer.

If you have a wooden deck, it can be quickly damaged by the weather without appropriate protection. To find a waterrproofing solution for your deck, consult with a contractor in your area. Be sure to ask about how long the waterproofing application lasts so you can avoid lapses in protection.
