Buyer’s Guide

Now that you’ve gone through some of the reviews for the best coating for wood trailer decks, it’s time to figure out what all the hype is about. Whether you’re still debating whether sealing your wooden trailer is worth it, if you even have to, or how often you should do it, we’ll break it all down for you here.

Why You Should Seal Your Wood Trailer

There are tons of benefits to sealing your wood trailer. The main benefit has everything to do with longevity. When you’re trying to get the most out of your trailer, it all starts with protecting the most vulnerable part – the wood.

Wood is susceptible to rot, warping, mildew, UV damage, and so much more. And since wood trailers spend most of their time outside and in the elements, this damage can happen faster than you think.

Sealing your wood trailer gives the wood a bit more protection, and this added protection adds years to the life of your trailer.

In fact, some untreated woods will start to rot in as little as three years. Meanwhile, if you seal these woods with the right sealant and keep up with it, there’s no reason the wood can’t last 15 to 20 years.

That’s a huge difference, and it highlights why you need to take the time to seal your trailer every few seasons.

Why You Should Seal Your Wood Trailer

How Much Sealant Do You Need?

When you’re ordering sealant, you don’t want to spend more than you need and get too much, but you also don’t want to not spend enough and find that you need more sealant when you’re halfway through the job.

That’s why we highlighted the average coverage area for each sealant on our list. Keep in mind that the porosity of the wood will affect how much you’ll need too.

Finally, when you’re calculating how much sealant you need, always add ten percent. This helps ensure that you won’t run out when you need it, and it’s common knowledge that manufacturers often try to make their product sound a little more effective than it really is!

How Much Sealant Do You Need?


How Often Should You Seal Your Wood Trailer?

It really depends on the sealant you go with in the first place. Some sealants can provide protection for up to ten years, and others you need to reapply every year.

The easiest way to test whether the wood is still good to go is to put some water on it. If the sealant is still working properly the water will stay clean and bead up. If the sealant is starting to wear down it’ll smudge up and start to look dirty, or even worse, soak into the wood.

When in doubt go ahead and reseal the wood. It might be a little more work, but it’s going to greatly increase the lifespan of the wood so it’s something you want to err on the side of caution with.

Also, if you’re a little rough on your wood boards because of what you haul, you probably want to reseal every year. When different items gauge into the wood it works its way past the sealant, giving water an opening to seep in and cause some damage.

Do You Need To Seal Pressure-Treated Wood?

Yes! While pressure-treated wood is the go-to choice for wooden trailer decks, that doesn’t mean you can skip the sealing process.

Pressure-treated wood does stand up better to warping and rotting, but it still won’t last forever if you just leave it out in the elements. Sealing pressure-treated wood gives you two different layers of protection, and that’s how you can get decades out of the wood boards on your trailer.

Do You Need To Seal Pressure-Treated Wood?


When you’re looking for the best coating for wood trailer decks, it’s only natural to have a few questions. We understand, and it’s why we took the time to highlight and answer some of the most frequently asked questions for you here.

How do you water seal a trailer deck?

Once you get the right product, like any of the ones on our list, sealing a trailer deck for the first time isn’t all that hard. Clean off the wood, let it dry completely, then brush the sealant into place.

Ensure that you’re sealing both the top of the wood and the ends. If you fail to seal the ends, it often leads to splitting, which can completely ruin your boards despite all the hard work you’re putting into them.

Give it plenty of time to dry and ensure that rain isn’t in the near forecast if you’re completing the job outside. Ideally, you want everything to stay completely dry for a full day or two after applying the sealant.

How long does it take wood sealer to dry?

It depends on the exact sealer you use, but most wood sealants take anywhere from 8 to 24 hours. Some fast-acting sealers can be dry to the touch in as little as five minutes, but that’s usually not the case.

Keep in mind that this is for the wood sealer to become completely dry to the touch. Before you expose it rain or heavy loads we recommend waiting at least two to three days to let everything dry completely.

Can you stain after sealing?

No. You want to stain before sealing your deck. The whole point of sealing your deck is to keep anything from working its way in, and that applies to stain as well. If you want to stain your trailer deck and you already have a sealant on it, you’ll need to strip the sealant off, stain the deck, then apply new sealant.

How do you reseal a trailer deck?

If you need to reseal a trailer deck, the process is extremely similar to sealing it for the first time. The only difference is that you need to strip the old sealant off first. You can put the stripper into a pressure washer, or you can brush it onto the area and scrub the old sealant off.

From there just clean the surface, let it dry, then apply the new sealant!


Now that you know a little more about the best coating for wood trailer decks, all that’s left is for you to purchase the sealant and get to work! Don’t put the job off because the longer you wait the more likely the wood on the trailer deck will start to break down, and that’s only going to cost you more money in the end.

So, get that sealant on order and get to work! Once you finish the job, you won’t have to worry about it for years to come.
