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.

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.
