Why You Should Seal Your Cedar Fence?

Why You Should Seal Your Cedar Fence

Ask any professional that has worked with wood for decades, and they will tell you that sealing wood is extremely useful. Whether you just set up a cedar wood fence or you’re looking to give your old one some renovation, applying a sealer is a great idea. Here are the reasons:

It Prevents Water Damage

Wood is porous. Unfortunately, the water it absorbs causes it to expand and crack and even rot. A sealer creates a barrier that prevents water entry and minimizes water-damage.

Stops Mold and Mildew

Because of the water it absorbs, unsealed wood attracts mold and mildew along with little insects like termites. Sealers discourage the growth of mold and mildew and also makes the wood uninhabitable for insects.

Prepares Wood for Painting

If you apply a stain/paint directly to wood, the pores in the wood will not allow the coating to sit well. Paint as a first coat will likely look blotchy or dull.

A sealer shuts the pores and allows the stain to go on uniformly.

Protects Wood From UV Rays

The sun causes unsealed and unstained wood to dry out and lose color. Sealing and staining create a filter that prevents the UV rays from hitting the wood, thus preserving its natural color.

Best Sealer for Cedar Fence Buyer's Guide

Cedarwood is an immensely beautiful building material, especially for the fence. However, without proper maintenance, it can quickly get damaged by elements such as water and UV rays.

To keep your cedar fence looking great, you may want to maintain it with the best-quality sealer for cedar fence. To help you get the right product, I have compiled a list of the factors you should consider.

Type of Stain- 

Like paints, sealers come with a range of stains. The major categories include:

  • Solid
  • Clear/transparent
  • Translucent/semi-transparent

The one you pick should depend on your preferences. Solid stain sealers come with an opaque color that completely masks the original color of your fence.

Clear sealers do not add any stain to the surface. They are ideal when you want to only seal the surface without making any change to the original color of the wood. These are perfect for new wood surfaces as they help retain the rich color.

Translucent sealers add color to the wood, but it is not so strong as to completely mask the original color. Moreover, they allow the grain and texture of the wood to remain visible.

Drying Time

Drying Time

Sealers take different timelines to dry. Some dry quickly and some do it slowly. The reason why this matters is that if, for instance, the rain falls on the applied sealer before it dries sufficiently, the application might get destroyed, requiring a fresh application.

Another reason why drying time is important is that when doing multiple coats, you have to wait for each coat to dry before applying the next.

If you reside in a place that has high humidity or the weather forecast is that the rain might come soon, you want a quick-drying sealer.

On the other hand, if you live in a place where it’s often sunny and dry, then you can get one that takes even 24 hours to dry.

Generally, water-based sealers dry in 4 to 6 hours while oil-based sealers take up to 24 hours to dry.

Moreover, while water-based sealers can take around 24 hours to cure, oil-based sealers could take up to 3 days.


When shopping for a sealer, you need to think about the size of what you’re sealing. If you’re only retouching a small section of the fence, even a gallon might be enough to seal the area.

In contrast, a wider area requires more product to seal.

Although sealers have varying coverage rates, the general rule is that a gallon covers 300 square feet. So, if you have 1500 square feet of fence space to seal, that means you need 5 gallons.

Keep in mind that oil-based sealers have better coverage than water-based ones. Moreover, while water-based sealers may require multiple coats, oil-based sealers usually do fine with just one coat.


When buying a sealer that is either translucent or solid-color, then you need to mull over the color. Wood colors vary greatly from light oak and dark walnut to pine and hickory.

Check whether the color of your wood is available in the array of options the seller is presenting for their product. Then, be sure to select the right color.

Water-Based or Oil-Based?

Sealers are usually either water-based or oil-based. The two classes have subtle differences that you need to mull over before you buy.

If you need something effective in terms of the protection level and durable as well, then an oil-based sealer is the better choice.

On the other hand, in case you want something that dries quicker and that is gentler on the environment, then a water-based sealer is the right selection.

In case you make a mistake when sealing with a water-based product, you can easily wash it out with water and soap. The same case applies to when you want to clean tools after application. It is much easier when the sealer is water-based. Removing oil-based sealers is more difficult.
