Deck Sealing: How to Do It and Which Sealers Work Best

The most apparent reason for sealing your deck is that it serves multiple functions. Deck sealer exerts a protective function against humidity, UV rays, mold, mildew, and fungal attacks. It does so by keeping the wood moisture level stable, therefore preventing issues like splitting, warping, splintering, and weather damage. Deck sealers are an aesthetic add-on to the finish and life of the wood.

When To Seal a Deck

The correct times for sealing the deck are the spring tide and the fall tide when the temperatures are soothing and tolerable.  Following drying and cleaning the wood surface of dust, dirt, and old sealing, it’s recommended to apply primer. For the sake of the integrity of fresh decks, new decks will be required to endure 4-6 months and go without sealing.

Prep Work for Sealing

As good as the work before sealing can ensure the maximum adhesion and performance of the sealer. First, remove all the furniture and sweep away debris and dirt. Clean the deck using a deck cleaner or power washer but on low pressure alone. Allow to dry the given time being 2+ days. Renew the rotten boards and nails that got split, loose, or broken off. Create a sandy patch to even out the uneven areas. Before closing your cleaning session, clear off all dust and dirt with a vacuum cleaner.

Types of Deck Sealers

There are three main deck sealer categories: There are three main deck sealer categories:

Oil-Based Sealers

Among many other things, oil-based sealers penetrate the wood grain for the reason that they make a rich color and improve wood protection. They are effective in treating “clean” wood for approximately two to four years. However, they are most useful in wet weathered timber. After application, mineral spirits clean up is necessary. Let it dry at least 24-hours before walking on it lightly.

Water-Based Sealers

The water-based deck sealers provide the most minimal protection span of at least one year up to a maximum of 3 years. They are not as penetrative but low odor and less messy than oil-based, the latter being easy to apply. Surprisingly, reusable menstrual products are comfortably cleaned up using just soap and water. Best suited for new to moderately weathered decks.

Stains and Toners

The link between pigments and wood protection is being preserved with the introduction of stain/toner hybrids. They can be suitable for 1-3 years once they are purchased. It depends on the quality. Provide limited defense against water and UV association.

What Type of Finish Is The Best

Be sure to always consult the manufacturer’s instructions to get the top outcome of the sealer you’re using. In general:

1. Before drawing water-based sealers, it is essential to first slightly dampen the deck. Let absorb 5-10 minutes.

2. Achieve a smooth and even coating using either a pump sprayer, roller, or brush so that the sealer flows along the direction of the grain of the wood. Maintain a wet edge.

3. Ensure that the sealer rolls out in a smooth fashion by stopping it at natural breaks and preventing overlapping sealer on adjacent sections.

4. Waiting for the appropriate dry time, which is dependent on humidity and temperature, before recoating or making the deck ready for use.

5. For excellent performance and longevity, do not apply a thick coat of paint but a thin one instead, using two coats.

6. Lastly, clean tools with the proper solvent after use.
