Knowing the difference between deck stain stripping and deck cleaning can be vital to your deck maintenance or restoration project. It’s important first to understand why cleaning a wood surface is necessary.
Besides the obvious of overall appearance and curb appeal, a wood deck should be cleaned and sealed every couple of years to prevent structural damage. Water and moisture wreak havoc on wood inviting mold and mildew which can lead to wood rot. The sun’s U.V. rays also damage wood fibers and turn them an unsightly gray. In colder climates freeze/thaw occurrences can warp, crack, and split boards ruining a deck in no time.
By cleaning the wood and protecting it with a quality wood stain, you are locking out moisture, blocking sun rays, and protecting the deck from the environment. This ensures a better overall appearance and a longer lasting wood structure.
Now that we have determined why cleaning a wood deck is necessary let’s uncover the differences between deck stain stripping and deck cleaning. Before applying any sealer to the wood it has to be cleaned properly. You need to use a deck cleaner to remove all the unwanted soils such as dirt, mold, mildew, and graying. This will guarantee a clean surface for the new deck stain.
The deck cleaner is mixed up as needed and normally applied with a pump sprayer. It should be allowed to dwell on the surface for several minutes to break up the unwanted soils. This is then followed up with a stiff brush scrubbing or light to moderate pressure washing to remove the contaminants. The deck is then rinsed and a deck brightener is applied to restore the pH of the wood and brighten the wood grain.
When an old failing wood stain or sealer is present a deck cleaner is usually not aggressive enough to remove it. In this case using a deck stripper instead of a deck cleaner will not only remove unwanted soils but also unwanted stain or sealer remnants. Deck strippers are a more aggressive caustic than a deck cleaner. They emulsify and soften most deck stains so they can be washed away with all the other contaminants. The deck stripping process is the same as deck cleaning with the applying, dwelling, and pressure washing. The only difference is the product used and like mentioned, that is determined by what is existing on the deck prior to cleaning. A deck brighter should also be applied following deck stripping.
Basically the difference between deck stain stripping and deck cleaning is whether or not there is an old deck stain present or you are just removing dirt, grime, graying, etc. Determine what is on the surface of your deck and use either the deck stain stripping or deck cleaning process, followed by deck brightening to prep the wood prior to staining.
