It can be frustrating to put so much effort into a project only to find it damaged, discolored and decaying within a few weeks. You might be wondering if sealing the wood surfaces after staining is necessary if you are already in that stage. Let’s find out!
Is It Necessary To Seal Stained Wood?
Wood becomes lifeless and dry without a sealant. Staining and finishing are not the same thing. While staining is used to darken wood or add pigments to it, they don’t protect the wood.
The wood will take on a dramatic look if the stain has been rubbed into it. The stain darkens wood and exposes its grain pattern. However, it does not protect it from the elements.
It is strongly recommended that you seal the wood stain immediately after it has been stained. A few coats of wood sealer can be applied to the stain to close the pores. This will reduce its ability absorb moisture and protect it from ultraviolet light. It can also prolong its life expectancy.
It is a good idea to seal and reseal wood and furniture every few years to extend their useful life.
What Is The Best Time To Seal Wood After Staining?
Before applying a clear coat to the wood stain, it must dry according to the manufacturer’s instructions. Otherwise, the stain can be pulled off or wiped off.
You’ll leave streaks in your wood stain if you apply the clear coat with a brush or wipe it on. We recommend spraying the clear coat instead. If you don’t allow the clear coat to dry, it is more likely that streaks or marks will appear in stained pieces.

What Happens If The Stained Wood Isn’t Sealed? What Are The Alternatives?
It is important to consider the intended purpose of the item. It will crack and warp even if it is hung indoors. The effect will not be noticeable, however.
The product will wear faster if it is used in an area that is subject to moisture, sharp objects or spills.
The workpiece will eventually appear worn and damaged from scratches, rot, wear, staining, denting, and other factors. The distressed look may be appealing to you but it will need more frequent replacement.
The most popular sealants for wood are oil-based polyurethane and water-based Polyurethane.
Waxing and hard-drying oils can also be used to seal stained wood. However, they require more work and a steeper learning curve than polyurethanes or alkyds.
Clear Coats For Stained Wood: How Many?
You must seal wood after staining it with at least three coats.
Clear coatings should be applied in three layers if you want to protect your surface from damage. We recommend applying wood coatings in 3 to 5 coats.
Clear protective coatings in thin layers can be time-saving and make it easier to fix any imperfections between coats.
Sometimes, a thicker final coat is applied to ensure durability. You can sand between coatings by using high-grit paper (between 220 to 600 grit).
Sand only between clear coat applications and don’t sand stained wood. Sanding directly on the stained area will not remove the stain, but it will leave behind major surface damage that others and you will be able notice.
How To Choose The Right Type Of Clear Coat For A Newly-Stained Wood
Project Type
Clear topcoats that you apply to items in high traffic areas like dining rooms tables must be strong. For smaller projects, these standards are not necessary.
Stain and color of wood
Clear coats can be completely transparent or have a golden hue to match certain wood stain colors. Be cautious and decide based on your personal preferences.
Easy Application
To apply a clear topcoat, a paintbrush can be used or a clean cloth. You can paint other types with a spray can or paint sprayer. How do you decide which route to take?
Indoor vs. Outdoor Use
What length of time do you intend to keep your stained surface outside or inside? Clear coats that are intended to be outside must be waterproof and UV-resistant.
Different Types Of Wood Sealing Products
Polyurethane (Oil And Water Based).
Because it is durable and affordable, this wood finishing material is very popular. A topcoat sealer such as polyurethane should not be confused with a sanding sealing agent.
Because of the yellowing caused by topcoats made with this material, they are not recommended for furniture painting. It is not a problem with paints of a lighter color but staining is a great alternative.
Re-apply polyurethane within one to two hours for touch-drying and a second coat. The dry time should not exceed 24 hours. Before using the sealer coat, let it dry completely.
Water-based polyurethane is not suitable for thinners. However, you can thin oil-based or alkyd polyurethane with mineral spirits at a
Polycrylic
The Minwax Polycrylic is our favorite finish for woodworkers. This sealer coat is a better choice than other clear coatings because it retains its transparent color even after it has been applied to paint.
You shouldn’t be concerned about applying a clear coat Polycrylic sealer to the stain. Customers who want to remove light-colored stains have found Polycrylic sealer to be transparent.
A grey stain is the most popular color because it is light and doesn’t get yellowed over time. Polycrylic is a way to keep the gray stain color.
Lacquer
The lacquer will dry in 30 minutes. You can sand between thin coats of lacquer and be ready to go. Lacquer can be very poisonous and have a strong odor.
You don’t have the right equipment to spray lacquer. Spraying lacquer uniformly is all that’s required. It is best to keep it indoors as it is not safe to be used outdoors.
It is possible to yellow or amber wood after application.
How To Seal Stained Wood + The Best Tips And Tricks
If the stain has not been stained, sealers are usually applied to the stain or the wood. Sealers close the pores of wood, giving it a smooth surface.
These are some tips to help you seal wood stain. These tips will help you achieve better results.
- Preparing the wood’s surface is key to achieving the desired effect. Surface preparation is important if you want a smoother finish. However, sanding the wood prior to staining is an option.
- Wood should have a moisture content of less than 12%. If the wood is too damp, it will appear blotchy. You can see how moist the wood is by placing a few drops of water on its surface.
- A dry surface is required for staining. It is ready if the wood absorbs the water. It is not dry enough if the water beads up or stays put for more than a few minutes.
- Be sure to let the stain dry between coats.
- Use a new brush each time you seal woodworkpieces.
- After cleaning the area with mild soapy water, use a lint-free towel or let it air dry. Staining wood requires that it is completely dry before you apply any stain.
- Before applying the dye, it is important to thoroughly mix the dye. Apply two thin layers of stain to the surface with a brush, or roller after waiting for an hour. Do not apply a sealant to the surface for more than two days.
- Remember that porous woods might require multiple coats of sealer.
- Wipe away any spillages as you apply the stain. This can be done with a brush. If you don’t, the stain will not look good on you.
- Avoid overlapping. Apply a damp stain to the dry stain. This will cause darker, more uniform lines. Do not let the areas between the moist edges dry out.
- Only use trusted brands if you want to achieve great results.
- Start by sealing scraps of stained wood if this is your first attempt.
Wood Stain And Sealer In One: Another Option
If you don’t want to use multiple products or multiple layers of sealers and stains on a piece wood, it is advisable to use an all-in one stain and sealer. This is a great option for beginners as it combines both the formulas.
FAQ
What is the difference between sealing and staining?
Sealers will prevent water from seeingping in and encourage decay. A stain will stop the wood from drying out, cracking, checking for signs of graying, and will also prevent UV light from entering.
Is it advisable to apply polyurethane to stained wood that is not completely dried?
We don’t recommend applying water-based or oil-based polyurethane to stained wood that isn’t dried. This will reduce the sealers’ adherence, which can lead to flaking or peeling.
If the sealer coat is applied to a wet stain it may not cure properly. You will need to start again.
How can you seal stained wood for outdoor usage?
Stain can be sealed for outdoor use by applying a tung or linseed oil coat. To preserve wood stains, you can use a protective finish such as varnish, polyurethane or lacquer. To protect and finish the wood, you can use a combination of stain and sealer.
Conclusion
It is up to you to decide if wood should be sealed after staining. It is recommended that you seal wood to protect it from stains and wear caused by foods, drinks, human touch, and piercing objects. Wood stain serves a primary purpose: to add color to natural wood.
Without sealing the wood stain, it will lose its vibrancy. A sealer coat will help the grain and colors stand out better.
