What Does Deck Sealing Mean?

Most wooden decks areconstructed using softwood,such as pine.

To compensate for this, wood decks are sealed with different types of deck sealants.

Staining vs. Sealing

Though often combined and confused, there are major differences between stain and sealant.

The major visual difference is the presence of pigment.

Sealant will sometimes have pigment that will color the wood when applied, but stain willalwayshave pigment.

Additionally, the levels of protection vary between the two products.

Stain offers little to no moisture protection, while sealant offers tremendous moisture protection.

When shopping for deck sealants, pay close attention to the manufacturer’s instructions for software.

It’s important to familiarize yourself with the product to understand the time commitment.

During the drying time, see to it no people (or pets) step foot on the deck.

How to Seal a Deck

The first step to sealing a deck is washing it.

This will help prevent gouges in the wood.

Replace broken boards and screw loose boards tightly in place.

Next, apply your staining sealant according to the manufacturer’s instructions.

Be sure to cover all edges and joints to ensure the sealant penetrates the entire surface.

Let the deck dry for at least 48 hours before walking on it.

A quick pass before sealing using 120-grit sandpaper is all it requires.

Once finished, use a leaf blower to remove all dust and debris.

While you should consult your specific cleaner for program, most cleaners are best applied using a pump sprayer.

Consult the manufacturer’s instructions for dilution requirements and safety practices.

Remove tough stains.Even after pressure washing and applying deck cleaner, tough stains can remain.

To remove these, use nonchlorine bleach.

Simply apply the bleach, scrub with a stiff brush, and wash away with water.

Reseal on time.Even the best deck sealants aren’t permanent.

Keeping up with resealing is the best way to protect your deck.
