Deck Sealing vs Deck Staining: What's the Difference?
Most people don't know the difference between deck staining and deck sealing. Both work to protect the wood in different ways. The former uses pigments to protect the wood from the elements. On the other hand, wood sealers prevent water from seeping into the wood and causing damage.

Deck staining and deck sealing can both benefit homeowners wanting to protect their exterior wood from the elements. However, there are some differences between the two. In this blog post, I will discuss all staining and sealing your deck. That will help you choose the best option for your exterior.

What is Deck Staining?

Staining your deck protects from moisture, precipitation, rot, mold, and mildew. Wood stains have pigments that protect the wood from graying due to UV rays. Stains also enhance the wood color, providing a more consistent pallet. Wood stain can last as long as up to 5 years.

Pros and Cons of Wood Staining

Wood staining has several pros and cons. Here I have listed a few.

Pros

    Chemicals: Some wood staining products can be hazardous to nearby plants and trees. Choose a product that is eco-friendly and easy to rinse with water.

When to Apply Stain on Your Deck?

Applying stain on your deck depends on several factors, including the type of decking material, weather conditions, and your personal preferences. Always test a small part of the deck before applying it to the entire plank. Also, apply the stain evenly and liberally, and allow it to dry completely.

What is Deck Sealing?

A deck sealer is somehow similar to a deck stain. It protects the wood from the elements - moisture, precipitation, insects, mildew and mold, and rot, but not from UV rays.
It is usually applied to the wood after it is treated with a stain or paint. They don’t contain pigments and hence don’t protect the wood from UV rays. For that, the natural oils found in wood easily dry out, causing it to gray or crack.

Deck sealers are usually clear in color and are available in different grades, which can be used for different purposes. These are usually made from acrylic polymers, polyurethane, silicone, or petroleum products.

Pros and Cons of Deck Sealing

Like any other product, deal sealers come with pros and cons. Here are some things to consider before making a decision:

Pros

    Protection: Sealing your deck will protect it from the elements and extend its lifespan.
    icon
    Cleaning: A sealed deck is easier to clean than an unsealed deck.
    icon
    Appearance: Sealing your deck can give it a nice shine and make it look new again.
    icon
    Colorful: You can find deck sealant in various colors. So you can customize the look of your deck.

Cons

    icon
    Process: Sealing your deck can be a time-consuming and messy process.
    icon
    Durability: You will need to re-seal your deck every few years to keep it looking its best.
    icon
    Dangerous: Some homeowners believe that sealed decks are more slippery than unsealed decks.

When to Apply Deck Sealing?

There are a few things to consider before you make the move. First, consider your deck's condition. If it's in good condition, you may not need to seal it. However, if your deck is deteriorating, or has sections that are prone to water damage, it may be a good idea to seal it.
Second, consider the weather. Sealing your deck in the winter can help prevent water damage in the spring and summer. However, sealing your deck in the summer can make it difficult to maintain in the fall and winter.

Finally, consider your budget. Deck sealing can be expensive, so it's important to weigh the cost against the benefits.

Do You Need to Seal the Deck After Staining the Wood?

There is some debate on whether or not you need to seal your deck after staining it. However, the consensus seems to be that you should seal your deck if it has been stained with a water-based stain.

Water-based stains will cause the wood to swell and contract. It can cause the wood to split and warp. Sealing your deck after staining will help to prevent these problems. There are a variety of sealers available that will protect the wood from moisture and UV rays. Choose the sealer that is best suited for the type of stain that was used on your deck.
