To give you a heads-up, sealing essentially prevents your deck from the effects of moisture. Therefore, when you apply a sealer, you are protecting against mold and mildew buildup. On the other hand, staining is vital for changing the original color of the wood. While some stains may safeguard the wood from moisture, they do not achieve the effectiveness of a sealer.


Applying A Deck Sealer

Applying a wood sealer allows you to use a brush, a sponge, or even a roller. For optimal results, ensure that you are following the directions which come with the sealer. This is so since the sealer or stain will have its manufacturer instructions.

For this reason, remember always to adopt a sealing pattern that will let you know where you have already applied the sealer to avoid reapplying the sealer or not applying the sealer on some parts at all. Also, worth remembering is that the sealer potentially requires up to two coats for it to soak in properly and for maximum wood protection.

Before applying the sealer, thoroughly clean your deck first. How should go about this? First, mix warm water with a high-quality oxygen bleach and brush the mixture onto your wooden deck surface. This should be followed by scrubbing of the surface using a long-handled brush. Scrubbing is necessary if you are to ensure that you remove any leaf debris, algae, or mold. The last step involves undertaking a thorough inspection for any rot or damage that could have occurred since the deck was last treated. This is the ultimate time during which any board repairs or replacements should be done. When you are sure that the deck is clean and cry, go ahead and apply the sealer.
