Top Reasons to Stain Your Deck

restaining a wood deck, completed deck

Protecting the wood from weathering and fading

One of the most prominent benefits of staining your deck is the added protection it provides against weathering and fading.

Stains help to block out the sun’s harmful UV rays, which can cause the wood to fade and deteriorate over time.

They also provide a barrier against moisture, helping to keep the wood from warping, cracking, or otherwise becoming damaged.

Enhancing the wood’s natural grain and color

In addition to the practical benefits, staining your deck can also add a touch of style and beauty.

There are many different wood stains you can choose from, each of which will enhance the wood’s natural grain and color in different ways.

Whether you want a rich, dark stain or a light, natural finish, there’s definitely a stain out there that will suit your needs.

Giving the wood a bit of extra protection from wear and tear

Wood decks can deal with heavy foot traffic, furniture, and more on a daily basis.

If you want to give your deck a bit of extra protection from all this wear and tear, staining it is a good way to do so.

A quality deck stain will create a tough, durable surface that will be able to withstand a lot of abuse. Just be sure to stain your deck during the right time.

Considerations When Buying a Wood Stains

Quality of the Stain

One of the most important considerations when buying a deck stain is the quality of the product.

There are plenty of low-quality stains on the market that simply don’t last as long or give your deck as much protection.

To spot a quality stain, look for one that is labeled as “UV resistant” and “mildew resistant.”

You can also choose from more reputable brands like Olympic, Behr, and Cabot.

Check out these best brushes for wood stain so you can get even coverage from your stain!


my deck

The color of your stain is another important consideration.

There are many different wood stains you can choose from, each of which will give your deck a different look.

If you want a natural look, you’ll want to choose a lighter stain.

But if you’re looking for something more dramatic, a dark stain will do the trick.

There are also different levels of transparency.

Some stains will completely opaque, while others, like a semi transparent stain, will allow some of the wood’s natural grain to show through.

Choose the level of transparency that will give you the appearance you’re looking for.

Type of Stain

There are two main types of deck stains: water-based and oil-based.

Water-based stains are easier to apply and clean up, but they don’t last as long as oil-based stains.

Oil-based stains last longer and provide more protection, but they can be more difficult to work with.

Wondering some other methods to treat untreated wood? Check out these ways to treat wood for outdoor use!

Type of Wood

Different types of wood will require different types of stains.

For example, pressure-treated wood is often treated with a chemical called chromate copper arsenate (CCA).

This chemical can make it difficult for some stains to penetrate and adhere to the wood.

If you’re staining pressure-treated wood, be sure to choose a stain that is specifically designed for that type of wood.

Other types of wood will allow for more flexibility when it comes to choosing a stain.


Some stains can be much more expensive than others.

Finding a quality stain doesn’t have to break the bank, but you may have to pay a bit more for a top-of-the-line product.

When it comes to deck stains, you usually get what you pay for but there are some great deck stains for those on a budget.


Some stains are easier to apply than others.

If you’re not experienced in staining decks, you may want to choose a product that is easy to apply and doesn’t require any special skills or knowledge.

When staining pressure treated wood, be sure not to stain it too soon or you could cause problems down the road.


The amount of stain you’ll need will have an impact on which stain you’ll end up choosing.

Be sure to calculate the square footage of your deck to determine how much stain you’ll need to buy.

Environmentally Friendliness

Oil-based stains can be harmful to the environment and are not as easy to dispose of.

If you’re looking for a more environmentally friendly option, water-based stains are a better choice.

Additionally, stains will contain harmful chemicals known as VOCs.

Be sure to choose a product with low VOCs to keep your family and pets safe.

How to Stain Your Deck: Step by Step

Choose Your Stain

Choosing the right stain is a critical step in staining your deck.

As we mentioned before, there are many different types, colors, and brands of stains to choose from.

Do your research and choose the option that is best for your deck.

Prep Your Wood

First, you’ll need to clean your wood and remove any existing stains or sealants.

You can do this by using a power washer, deck cleaner, or sandpaper.

If you’re staining a deck with peeling paint or old stain, you’ll need to remove as much of the old finish as possible.

Once your wood is clean and dry, you’re ready to move on to the next step.

TIP: Never stain damp wood.

Stir & Shake Stain

Before you begin the staining process, be sure to stir and shake your stain well.

This will help to ensure that the color is evenly distributed to give you a proper finish.

If you have a paint stick, you can use it to stir the stain.


Finally, it’s time to start the staining process.

To do this, you’ll need a paintbrush or roller specifically designed for use with stains.

Start by applying the stain to the edge of your deck and then work your way in.

Be sure to cover the entire surface of the wood.

TIP: If you’re working in direct sunlight, be sure to apply a thicker coat of stain to prevent the color from drying too quickly.

Let it Dry

Once you’re finished, let the stain dry completely before walking on it or applying a sealant.
