During the warm summer months, the best memories with family and friends are made outdoors. Think of how much fun you’ve had as a kid and adult at swimming pools, boating, and in outdoor decks. These are some of the most pleasurable times of our lives, cooling down in the water or entertaining loved ones. 

However, there are investments to be made to enjoy these finer pleasures of life. Some of us invest in boats, swimming pools, and the construction of outdoor decks.

Considering that’s already a lot of money, we also need to ensure that our investments are protected by maintaining them properly. Pool decks, wood docks, and decks that are situated near open water mean that they are constantly exposed to their biggest threat: water. 

Over time, these types of wooden outdoor furniture can end up fading due to damage caused by the sun, water, and saltwater. Once they do fade, restoration can be a pretty pricey project. It’s also extremely tedious to have to remove mold, mildew, and algae on your own. 

Aside from that, wood is also prone to decay over time. Wood is meant to last a very long time as long as it’s protected from the elements too. That’s why sealing wood is necessary.  

Meet Marine Wood Sealer, the best friend of outdoor wooden furniture. This sealer was designed to be used around fresh or saltwater and utilizes state-of-the-art nanotechnology that can penetrate deep into the wood, providing long-lasting protection.

Though there are many types of wood sealers in the market, what makes this product stand out is the fact that it’s made to be completely non-toxic and safe for you, the environment, and marine life. Truly eco-safe for use for a variety of outdoor wood furniture, and best of all, it does the job well. 

Seal Once Marine Wood Sealer is a top-of-the-line wood sealer formulated for use on wood in environments exposed to high moisture. Whether it’s pools, lakes, rivers, ponds, or oceans, this sealer has got you covered, preventing decay and water damage while extending the life span of your furniture. 

Thanks to its superior nanotechnology that Seal-Once is known for, it coats the wood down to its cells, forming a barrier just below the surface. The barrier is extremely breathable too which means that your wood can easily breathe without trouble. 

As a result, water vapor escapes efficiently, and water damage is a problem of the past.

Whether your wood is old or new, Seal Once Marine Premium Wood Sealer works to preserve and extend it. It doesn’t leave any film, so you don’t have to worry about surfaces becoming slippery.

In love with the natural beauty of your wood (who isn't’)?

Well, more good news is that this sealer doesn’t change the beauty of your wood. If anything, it only makes sure that your wood stays beautiful for years to come. The integrity of your wood is preserved because of this sealer’s ability to inhibit the growth of mildew, mold, and rot while preventing cupping and warping. 

Seal-Once Marine Wood Sealer is completely non-toxic: it’s safe for people, plants, pets, and marine life. Its water-based formula performs just like an oil-based sealer but without the side effects and harmful chemicals.

What People Are Saying

Though we know for a fact that Seal Once's Marine Premium Wood Sealer is a trusted name in sealing wood furniture in high-moisture areas, we wanted to see what customers themselves had to say after using this product.

Based on reviews online, customers are raving about this sealer. It works as it’s promised, and for many customers, they’ve even written in that it has exceeded expectations in performance. Many have said that its results are superior to others that claim to specialize in outdoor wood, even if they have tried many in the market.

It’s also important to customers that they were able to rely on a water-based, non-toxic sealer that works well. They also appreciate that it’s virtually odorless, as many of the most popular sealers in the market are notorious because of strong fumes.

However, there was just one review we found from a homeowner who was disappointed that the results were a milky finish. Some also found that it was difficult to remove dirt from the wood after sealing, though they admit that Seal Once Marine Premium Wood Sealer still does a great job at protecting wood.

Overall, it’s clear that Seal Once Marine Premium Wood Sealer is still the sealer of choice for homeowners with outdoor wood furniture.
