Get matched with top deck staining pros in Lake Andes, SD

Yes, you must thoroughly clean your deck before staining. If you don't, dirt, debris, grease, and mildew can get trapped between the wood and the new stain. This not only looks unsightly but also prevents the stain from penetrating the wood properly, reducing its ability to protect the deck from weather and UV rays. As a result, the stain won't last as long or look as good. Any existing mold or mildew left untreated can continue to grow beneath the new stain, potentially leading to wood rot and structural damage. Always wait at least 48 hours after cleaning for the wood to dry completely before applying stain.

Oxygen bleach uses hydrogen peroxide as a base and won’t harm wood when using it as a cleaner. On the other hand, chlorine bleach breaks down wood at the cellular level and causes irreversible harm. Although you may not see immediate damage to wood after exposing it to chlorine bleach, its strength and integrity are now compromised.

Applying too much sealer to a deck might seem like extra protection, but it can cause more harm than good. Wood is a porous material with a limited capacity to absorb liquids. When you go overboard with sealer, the excess can't soak in and instead forms a film on the surface. This leftover layer is prone to peeling, cracking, and trapping moisture, ultimately defeating the purpose of sealing in the first place. 

Provided conditions are ideal, staining an entire deck should take as little as a couple of hours and up to a couple of days to apply and cure. Additional procedures, like sealing a deck or using additional treatments, may extend the project by a few additional days.
