How to Stain a Fence

Recommended Use

Wood Defender™ fence stain is designed to be used on exterior wood fences. Both the Wood Defender Semi-Transparent and Transparent Fence Stains work extremely well on:

  • Pine
  • Cedar
  • Spruce
  • Redwood
  • Pressure-treated wood
  • Weathered and previously stained wood fences

The recommended spread rate for unsealed wood is 150-250 square feet per gallon. When applied at this rate, the Wood Defender line of Fence Stains will provide you with a uniform application.

Preparing the Fence

As with any staining project, it is important that your substrate (wood fence) is properly prepared. The surface of your fence must be clean, dry, and free of dust, dirt, mildew, oil, water, and other contaminants. Weathered wood must be bleached prior to staining to kill any mildew spores present.

Staining the Fence

Wood Defender recommends the following steps when staining a fence:

  • Wood Defender Stains can be applied by spraying, brushing, or rolling as long as total saturation of the wood surface is achieved.
  • Test color choice in an inconspicuous area before proceeding with the project.
  • Stir stain thoroughly.
  • Apply without thinning.
  • Apply stain above 50 degrees Fahrenheit (10 degrees Celsius).
  • Allow 90 days for total cure on Wood Defender Fence Stains.
  • We recommend the use of a respirator while spraying.
  • Do not apply product if rain is expected within 24 hours.

By saturating the surface of the lumber, the Wood Defender product penetrates deep into the wood, leaving the fence with an even, uniform finish.

The Cleanup

Wood Defender Fence Stains wipe off most metal, glass, and non-porous surfaces; therefore, cleanup is less time consuming. Metal gate hardware and fences built with metal poles can be wiped off with a dry rag to remove stain. Wood Defender EZ Clean is the recommended product for removing the stain from surfaces you didn’t intend it being on. Wood Defender EZ Clean will remove overspray from windows, air conditioners, gutters, brick surfaces, cars, garage doors, and pool equipment, and actually leave the job site cleaner then it was when you started!

Dispose of stain-soaked rags in a metal container filled with water. This will alleviate the possibility of spontaneous combustion.



What materials and tools do I need before staining wood?

All Wood Defender exterior wood stains can be applied with a brush, roller, or a pressurized spray system. Applying the material with a sprayer increases job-site efficiency and profitability. If total product saturation is met, the structure will have a uniform appearance with no drips, runs, or lap marks visible. A mixture of degreaser and soap is very beneficial in cleaning up any overspray that may end up in undesirable locations. Our Wood Defender EZ Clean™ will make overspray cleanup very easy on nonporous surfaces like windows, painted surfaces, and gutters.

What are some wood-staining essentials?

The wood must be dry and free of dirt, mold, and mildew prior to application. If the stain is applied to total saturation, there will be no drips, runs, or lap marks visible.

My fence or deck is weathered and has turned gray. What should I do?

The gray appearance that you see on the surface is mold and mildew growth. If mold and mildew are present, the wood can be low-pressure cleaned with a chlorine-bleach solution or a deck brightener to restore the surface to the natural look. The wood needs to be dry before stain can be applied. It is best to wait to stain 24-48 hours after the cleaner or brightener has dried, depending on temperature.

Should I pressure wash my wood fence prior to staining?

We only recommend pressure washing a fence if you are trying to remove a water-based, film-forming stain product from the surface. A caustic stripper and brightener may be used to aid in the process. Pressure washing can damage the surface of the wood and leave permanent etching that the stain may not cover up. It is not necessary to pressure wash between maintenance coats of Wood Defender.

Should I pressure was my new wood deck prior to staining?

We only recommend light pressure washing a new deck to remove any dirt or stains from pets, barbecue grills, foot traffic, etc.

How do I protect my driveway or sidewalk near my wood fence?

Porous surfaces like concrete, stone, brick, and masonry can be treated with water prior to application of stain. Use a mixture of dish soap and water to help the area that you are trying to protect stay wet longer during warmer months of the year. When the stain comes in contact with the wet surface, it will float on top and can be easily rinsed away to a safe area. Always take extra safety precautions with wet or soapy surfaces. It is best to wait to stain 24-48 hours after the water (or soapy water) has dried, depending on temperature. It is very important to keep the wood dry during this process.

Do I need to apply a wood stripper prior to application?

While a maintenance coat is needed on all Wood Defender products, it is not necessary to apply a wood stripper prior to application. The only time a wood stripper is needed is when you want to apply Wood Defender on an existing structure that has a latex product or latex paint previously applied.

Do I need to apply a wood cleaner prior to application?

A wood cleaner may be necessary on decks to remove stains caused by barbecue grills, pets, dirt, etc.

Do I need to sand wood prior to wood stain application?

Sanding the surface can close the pores of the wood and may inhibit the penetration of Wood Defender Fence and Deck Stains. If sanding is necessary, we prefer using a 60-grit, coarse pad to help prevent closing the wood pores.

What type of wood filler compounds are recommended?

If wood fillers are necessary, we recommend seeking a product that is stainable with an oil-based material. It would be best to test the product with Wood Defender on a scrap piece of the same lumber as your structure prior to placing it on your structure.

What happens if I get stain in my pool while spraying?

We always recommend covering any nearby swimming pools or water features prior to the stain process. If some stain does make its way to the pool, the stain will float on top of the water’s surface. It can be cleaned and restored back to normal. Please give us a call and we can help you with this process if it were to happen.

What will happen to my grass at the base of my wood fence?

There will be discoloration of the grass at the base of the fence if the stain is applied by a sprayer.  During the growing season the grass should rebound within three to six weeks on an irrigated lawn.

Do I need to cover my plants or shrubs near the wood fence?

We recommend covering all delicate vegetation near the fence if you choose to spray your fence. Canvas drop cloths or old bed sheets work well for this purpose. They allow the vegetation to breathe while covered and are less harmful to the plants than tarps or plastic in warmer months.

Will Wood Defender hide my sprinkler marks?

Sprinkler marks will appear on a new fence within weeks of install. We always recommend having your sprinklers adjusted so they do not strike your fence and damage both the stain and the wood. We recommend our Wood Defender™ Semi-Transparent Fence Stain for any fence that has damage caused by sprinklers. This formula will aid in making the prior damage less visible after application.

Can you stain a fence that has both old and new sections?

Yes, we recommend using the bleach process to remove any mold or mildew present on the aged sections of fence prior to the stain application. The solution of bleach is mixed with water and applied at low pressure. After proper cleaning, when the fence is free of mold and mildew, stain can be applied to the entire structure, making the entire backyard more uniform. There may be a slight variation when you compare the new to the old due to the porosity of the wood of the aged surface. Generally, the older surface will be a little darker and richer because it is able to absorb more product. We recommend our Semi-Transparent formula anytime you have this particular situation. It contains more pigment and will make the structure more uniform in appearance.

Is it difficult to stain around metal poles or other non-wood components that some wooden fences have?

Wood Defender Fence Stain will not dry on metal poles or gate hardware. We advise our contractors to put posts and hardware last on their cleanup checklist before they depart to the next job site. The product can be removed with either a dry wipe or by applying mineral spirits to the metallic surface to aid in the cleanup process. This is a direct increase in job-site efficiency. Time does not have to be spent taping or masking off posts and hardware in preparation to apply Wood Defender Fence Stain.

What happens if I get stain on the concrete?

It is best to try to prevent any stain contact with porous surfaces by pre-wetting these surfaces with water. The water will fill the pores of the surface, preventing the stain from penetrating. You can then simply rinse off the overspray once you’re done working in that area.


What kind of equipment do I need to stain Wood Defender?

A high-quality garden pump sprayer is the method we recommend for a homeowner wishing to stain their own fence. Many contractors prefer a commercial-grade spray system with high-capacity tanks and longer spray hoses to increase their job-site efficiency and complete multiple jobs in a day. We build a full equipment line for contractors who have the desire to maximize their profit margins and productivity.

Do I need special equipment to stain with Wood Defender?

As long as the product is applied to total saturation, the appearance is the same whether you use a brush, roller, garden sprayer, or professional piece of equipment like the Wood Defender ST-250 Spray Machine.

Can I use a brush or roller to apply Wood Defender?

Brushes and rollers can be used for smaller projects like benches, playsets, shutters, etc. On larger projects like fences, decks, pergolas, and siding, a sprayer will be the most efficient way to apply Wood Defender.

Does Wood Defender offer spray equipment?

We do offer a full equipment line for contractors to take their business to the next level with job-site efficiency and maximize profitability. All of our spray systems are high-volume and low-pressure to ensure total saturation. We offer options that range from small portable 12-volt systems to our ST-250 Pro Package. Please contact us with any questions about our Wood Defender equipment line.

Can I store Wood Defender Stain in my Wood Defender Equipment?

Yes, all of our Wood Defender commercial grade equipment is built and designed for job-site efficiency by allowing Wood Defender product to be stored in the tanks when the unit is not being used. When using our equipment, there is no need to flush the system with solvents at the end of each day. The Wood Defender stain and equipment are designed to work together. The stain will not cause a film in the tanks or cause any damage to the pumps or hoses from product being stored in the system.

What species of wood can the Wood Defender Fence Stain be used on?

All Wood Defender Fence Stains can be used on cedar, pressure-treated pine, SPF, redwood, and cypress, which are the most common species installed by fence companies in the United States.

Can you stain pressure-treated wood?

Pressure-treated wood can be stained as long as the wood has had ample time to cure and dry from the treatment process. It is best to allow it to cure for 90-120 days, depending on UV-exposure and temperature. This will also allow the tint to dissipate from the treatment process, resulting in a more desired stained finish.

All of our Wood Defender stains are extreme-climate formulas. They can be used in hot and humid climates as well as cold and wet climates if properly applied.

Is it necessary to use a clear sealer or polyurethane on Wood Defender after applying?

It is not necessary to apply any type of product to your structure after applying Wood Defender. All of our products are a stain and sealer all in one. Adding another product will make it very difficult to apply a maintenance coat when your structure needs a refresh, years down the road. The other product could peel or blister, causing your Wood Defender-stained structure to have an undesired appearance.

Do I need to worry about the stain freezing?

No, our Wood Defender products are oil-based and will not freeze. They are packaged in steel containers, so we do recommend storing them in a dry area to protect the pails and labels.


How do I choose the right wood stain color?

Under the products page you can see the colors available on multiple species of wood. We always recommend a test sample if you are trying to match colors. Liquid sample bottles are available if you would like to test the product on your wood. Many Wood Defender Certified Contractors have sample boards that they can show you.

Does the stain color look different on new wood than aged wood that has been cleaned?

Yes, there may be some slight variation in color between new wood and aged wood. New wood tends to be more dense and absorbs less material than aged wood. As wood ages, the pores will open, allowing them to absorb more material and resulting in a darker and richer finish.

I have an older and weathered wood structure. Which wood stain would you recommend?

After the wood is free of dirt, debris, mold, and mildew, we always recommend our Wood Defender Semi-Transparent Stains for structures that are weathered. They excel in providing a more uniform look and help hide the imperfections of the wood that may be left behind.


How do I mix the stain for use?

Making sure the stain is properly mixed is very important in achieving a uniform appearance. We recommend removing the lid and stirring the product as the first step. Next, transfer the product to a clean, empty container so you will be able to access the bottom of the original pail. Add a small amount of mineral spirits to the bottom of the pail and agitate with a paint brush to lift up any pigment or solids that may have settled to the bottom. When that is done, you can pour the stain back in the original pail to thoroughly mix the material. Once all these steps are complete, you are ready to protect your investment with Wood Defender.

What temperature can Wood Defender be applied?

As long as the wood is dry, we recommend applying the product at temperatures above 50 degrees.

How long do I need to wait after a rain to apply Wood Defender?

The wood needs to be dry with a natural moisture content of less than 13% prior to application. In the warmer months of the year, it is usually dry within 24 hours of rain. In fall and winter months, it may take 48 hours or longer for the wood to dry.

How long do I need to wait after cleaning the structure to apply Wood Defender?

What is the best application method?

Wood Defender Fence and Deck Stains can be applied to any wood surface through brushing, rolling, or spraying. Contractors often choose spraying as their method of choice due to job-site efficiency and reduced labor cost. Regardless of the application method, the fence or deck will look the same as long as the wood is saturated with Wood Defender.

How do I know if I have applied enough Wood Defender?

You want to apply the product to saturation on the surface of the wood. If you follow this procedure, all drips, runs, and lap marks will self-level. If you see lighter areas in the stain, they can be touched up to match the rest of the structure.

Do I need to back-brush Wood Defender?

You do not have to back-brush Wood Defender Fence Stains. We do recommend using a roller or brush to level out any puddles on horizontal surfaces with the Wood Defender 200 Series. This product has a more accelerated dry time and puddles left behind will cause a pigment buildup that will be noticeable after the stain cures.
