After Staining Wood Do You Have To Seal It? (Answered)
No is the quick response to this frequently asked topic in the field of wood finishing.
The answer, in a word, is yes. When it comes to your projects, in all honesty, you don’t have to do anything that you don’t want to do at any point.
Nobody else has ownership of them, but you do.
On the other hand, an incomplete deck stain will only have some elements that you might be highly interested in seeing.
So, for instance, he has to have a transparent layer over the top of the stain so that he can see the actual color that the stain was designed to appear like.
But, again, this was done so that the stain could be seen.
Another problem is that the stain wood does not provide any protection from the outside elements.
So even if you enjoy the color, there is a chance that moisture and humidity will still have a detrimental impact on your tranquility.
On the other hand, you are free to omit the topcoat if you so choose.

Do You Have to Seal the Wood After You Have Stained it?
Sealing wood after staining is necessary to protect it from damage and discoloration caused by foods, liquids, human touch, and objects that pierce.
These types of exposure can cause the wood to become discolored or damaged.
However, the coloring of natural wood is the principal function of wood stain, even though it may also seal pores and provide some protection from damage caused by moisture and water.
Why You Should Seal Your Wood After Applying Stain
Sealing may need you to put in some additional labor on your wood staining project; nevertheless, the benefits of sealing significantly exceed this minor drawback.
The process of sealing protects from wear and tear.
As was just stated, stains offer very little in the way of protection to the wood to they are applied. Its primary function is to impart color to the wood and bring out the inherent grain pattern.
Additionally, the stain will penetrate the wood pores and shut them, providing some degree of protection against damage caused by moisture and water.
Because the stain does not form a film on the surface of the wood, the pores on dyed wood are unable to close off and remain partially open completely.
As a consequence of this, water and other liquids are still capable of causing damage to the wood, particularly as the stain begins to wear away.
The sealing process creates a protective coating impermeable to liquids of all kinds, including chemicals, water, and moisture.
In addition, the wood’s surface is protected from scratches by the hard surface, which also acts as a buffer.
Sealers are used to help prevent stains and discoloration.
The surface of stained wood can acquire scuff marks through frequent contact with liquids and foods, as well as from human and animal actions.
That can be avoided by using a sealer.
Applying a protective sealer results in forming of a harsh coat that serves as a barrier between the piece of wood and the environment.
Because of this additional barrier, the wood will be shielded from any contamination caused by environmental factors.
Because the wood surface has a glossy finish, it is also very simple to clean.
However, a significant portion of the dirt, grease, and filth that comes into touch with it will not adhere because of its slippery nature.
Because of this, you should be able to keep the surface of the wood in an immaculate and orderly condition by washing it down regularly and dusting it.
The use of sealant protects against fading.
Using a sealer after staining a surface helps preserve the stain’s color.
As long as the wood is sealed, it can maintain its color even after being subjected to various weather elements.
The aesthetic value of wood can be improved through sealing.
A clear coat helps improve the appearance of the wood by giving it a more polished appearance.
This flawless appearance can be maintained for a considerable time because the wood is resistant to scuffing and denting.
How long should I wait before sealing the stain after letting it dry?
Drying duration might vary significantly between different kinds of wood stains.
Therefore, the manufacturer will frequently specify the time between applications before applying the sealant.
In most cases, this period can be as little as four hours or as long as 24 to 48 hours.
When applying a clear coat over stained wood, you must wait for at least 8 hours, preferably overnight, before beginning the process.
Then, you can test your stained surface by touching it to see whether it’s ready.
If the treated wood is no longer tacky to the touch, you may apply the clear coating.
What factors affect the time it takes for the wood stain to dry?
Even stains with fast drying durations can take more time to dry depending on the type of stain, the amount of moisture in the substrate, and external variables such as the weather.
If the temperature is low, the humidity is high, or the moisture content of the exterior wood is high, you should anticipate the drying time for the dyed wood will be longer.
Take into account the forecast, and stick to the manufacturer’s instructions.
Recommendation. It is preferable to err on the side of caution and wait for as long as 72 hours before sealing the wood than to try to seal it before it is scorched.
You can learn how to dry wood stains more quickly and effectively if you exercise sufficient patience.
Dangers are posed by applying a finish to dyed wood before it has had a chance to dry.
Two potential risks are involved when a stained surface is sealed before it is scorched.
First, if you apply your clear coat using a foam brush, tack cloth, or pad, you run the danger of wiping the stain or leaving streaks in it.
Second, because the area beneath the sealed surface is still wet, it will likely take more time for the surface to dry completely.
Even while spraying the clear coat can help you avoid the first risk (streaking or wiping away the stain color), you may still have to wait significantly longer for the wood to dry once it has been coated.
Additionally, you run the risk of the surface becoming blotchy.
Over the wood that has been stained, how many coats of sealer should I apply?
In most cases, applying two coats of sealer is sufficient to close the pores in the wood and provide a suitable level of protection for the wood grain that has been sealed.
On the other hand, you can apply additional coats if you want your wood to have increased durability and a thicker protective coating.
In any event, you need to make sure that you provide sufficient time for each layer of sealer to cure before applying any additional coats.
On the packaging of the sealer, there should be some indication of how long it takes for the sealer to dry and sanding sealer instructions.
Does the Stain Need to Have a Clear Coat Applied Over It?
Applying a coating on top of the stain is not required, but doing so is essential to protect the stained wood.
Although it adds depth and richness to the color of the wood, staining does not give protection in the long run.
A stained wood surface that does not have a topcoat may become damaged if it comes into regular contact with water, chemicals, food, or sharp objects.
The Clear Coat that is Ideal for Applying Over Stained Wood
When it comes to applying a clear finish over stained wood, you have a few different alternatives.
In this part, we look at the best options available depending on various factors, such as clear coating for kitchen cabinets.
Polyurethane
Poly is a plastic resin that can be derived from either oil or water.
It takes the form of a liquid, and when it dries, it forms a protective layer that can be applied to wood or other substrates, such as concrete or metal.
It is made up of molecules that have been precisely formulated to establish strong bonds with one another when the product dries, producing an impermeable layer on the exterior of the substrate.
The application of this composition results in a wood finish that is significantly more resistant to the effects of abrasion, moisture, solvents, and other types of impact.
The advantages and disadvantages of polyurethane
Pros
- Spraying is a simple and effective method for applying the substance.
- Compared to the various clear coats discussed in this book, polyurethane provides the highest shine and protection.
- This is a dependable and long-lasting product.
- The clear coat of water-based poly doesn’t turn yellow over time like oil-based poly.
- Using a spray-on poly can help novice do-it-yourselfers create a finish that looks expertly done.
- Because there is such a wide variety of polyurethane available, consumers have a more significant number of opportunities.
- In contrast to lacquer and polyacrylic, poly is an excellent choice for use in the open air.
Cons
- It takes longer for polyurethanes, mainly the kinds that are oil-based, to dry because the plastic polymers that make up the polyurethane take longer to harden.
- Yellowing over time is common in oil-based polymers.
Minwax Polycrylic
The Polycrylic Protective Finish is a topcoat that is water-based and completely transparent. When applied on top of a water based wood stain or water based stain, this product does a fantastic job.
It can be applied to painted surfaces or unfinished outdoor wood.
The benefits and drawbacks of polyacrylic
Pros
- Because it is water-based, the product is straightforward to clean up after use.
- It does not have a scent, is safe for the environment, and does not emit any hazardous gases.
- It dries quickly, which helps you save time throughout the application process.
- Applying polycrylic is simple; all you need is a paintbrush, rag without lint, or spray gun.
- It never turns yellow and maintains its brilliant clarity over time. Because of this, it is an excellent choice for applying a transparent layer over tinted and light-colored wood stains.
Cons
- It can be challenging to utilize polyacrylic on larger woodworking projects because it dries very quickly.
- Due to the fact that it has a runny viscosity, applying it can be tricky unless you spray it directly on the surface.
- It is not appropriate for usage in the great outdoors.
Lacquer
In woodworking, lacquer is often considered one of the best options for finishing wood. Shellac, dissolved in either synthetic chemicals or alcohol, makes up the entirety of this drug.
When the product is allowed to dry, it creates a durable protective finish that may be applied to substrates such as wood or metal.
The item can be purchased in several formats and utilized in various ways.
For example, you can use a paintbrush to apply lacquer to your object like any of the other precise coating products on this list or spray it on.
Spraying the finish on large projects is the most financially viable application method because the finish dries virtually immediately after it is applied.
However, applying lacquer with a brush can be tricky, even on straightforward projects.
The advantages and disadvantages of lacquer
Pros
- In comparison to polyacrylic, lacquer dries much more quickly. This can assist you in reducing the amount of time spent on the application.
- It has a reasonable price, and you should only need a few spray cans to do a project of moderate size. Getting the more extensive tin can options will not set you back an excessive amount of money.
- It produces a finish that is long-lasting for use on interior applications.
- Lacquer dries fairly instantly, in contrast to polyurethane, which can entrap dust during the drying process and takes several hours to cure completely. Thanks to this solution, there will be no place for dust to become caught during the drying process.
Cons
- Lacquer dries quite rapidly. Because of this unfortunate fact, utilizing a brush-on lacquer for a large project can be very difficult and time-consuming.
- Because of its potent odor, lacquer can be challenging to work with if one does not use a respirator. When working with lacquer, you also need to wear protective gear since the fumes produced by the lacquer can be harmful to your lungs.
- When exposed to direct sunlight, the lacquer finish does not hold up remarkably well. As a result, you are restricted from working on initiatives that take place inside.
Things to Think About Before Applying a Clear Coat Over Stained Wood
To choose the clear wood finish that is best for your project, you need to know what characteristics to look for in a product and whether or not it is compatible with the stain you want.
The scale of your project
The project’s scope is the first factor to consider when selecting a clear coat and determining how to apply it.
For example, using a brush-on lacquer or polyacrylic will be a bad idea if you are working on a vast project.
Whether painting or using a sealer, you must do this first before obtaining an even coating.
Spraying is an alternative worth considering, mainly if you are new to the DIY world.
You will be able to apply the product much more easily and quickly with the help of a paint sprayer, and you will also be able to keep up with its rapid drying rate.
Location of your project-indoors or outdoors
If you want to utilize a piece of stained furniture outside, do you need to seal it first?
If you answered yes, you might instantly exclude lacquer and polyacrylic finishes from consideration because neither one is appropriate for use in an outdoor setting.
A lacquered or polyacrylic coat may suffer damage much more quickly than anticipated if exposed to direct sunshine.
For those working on outside patio furniture, oil-based polyurethane will be your best bet.
The product is tough enough to maintain its integrity even when exposed to the elements.
Additionally, it improves protection against the sun’s damaging effects on wood.
The utilization of what you’ve created.
In addition to the artwork’s dimensions, it is also essential to consider how you plan to put the stain to use.
You want to use something other than polyacrylic to protect the top of your kitchen dining table.
Although it creates a topcoat resistant to wear and tear, the product could perform better under heavy use.
Polyurethane is the material of choice when it comes to pieces of furniture that get a lot of usages, like the kitchen or dining room table.
Not only is it long-lasting, but it is also strong enough to bear pressure.
Ease of operation
While applying your sealer coat, you want to avoid any frustration.
For example, when staining wood, you can use a brush or a lint-free cloth to apply clear coat finishes that dry slower, such as polyurethane.
However, solutions like lacquer that dry quickly must be applied via spraying.
Think about lacquering the item or using Minwax Polycrylic if you want the task to be completed in a short amount of time.
If you instead take your time and wait for several hours between coats, consider using a sealer that dries more slowly, such as polyurethane.
The hue of the wood and the stain
Stains of lighter colors will call for clear, thinner coats that are not yellow. In this scenario, the most profitable products are those based on water, such as polyurethane and polyacrylic.
Lacquer or polyurethane that is oil-based can turn yellow with time, changing the color of the surface you’ve finished.
If you don’t like the amber hue, choose a finish made of water-based poly or polyacrylic for your project.
A stain composed of either water or oil.
Oil and water are incompatible substances.
Therefore, you will want to make sure that you seal a stain based on water with a comparable sealer based on water, and you will want to seal an oil stain with a sealer based on oil.
On the other hand, lacquer ought to work for both kinds of stain and gel stain so long as the surface is cleaned and prepared before the lacquer is applied to seal it.
FAQ on After Staining Wood Do You Have To Seal It
Should the wood be sealed once it has been stained?
Sealant should be Applied as Required.
It is not necessary to apply a topcoat sealer, but doing so will ensure that the stained wood does not become scratched and that it does not lose its color over time. If you are using a brush to apply a polyurethane finish, you should apply one to two coats.
What steps should be taken following staining?
Once the stain has had sufficient time to dry, it is time to apply the initial finishing coat. Keep in mind that you are applying the stain on unfinished wood; thus, you will need to seal the stain in order to protect it. After you have opened and stirred your polyurethane, apply it with a brush.
Does painting wood make it waterproof?
Stains are applied to wood to improve its color and to make it more resistant to the elements. However, although sealants protect concrete and wood from moisture, they do not prevent water from the outside from moving through the concrete.
How much time passes until the surface is sealed after it has been stained?
It is recommended that you wait a full 24 hours before applying polyurethane sealer to your workpiece after the stain has been applied. This is because the majority of regularly used stains require between 12 and 24 hours to thoroughly dry and cure after they have been applied.
Should you seal the stain after applying it?
In order to stop bleeding, the majority of stains should be sealed. After the coloured wood has been sanded and smoothed, a sealer coat of thinned shellac, sanding sealer, or another suitable sealer should be applied. Shellac should not be used in conjunction with NGR or water-base stains. Be sure that the sealer you use is suitable with the polyurethane that you intend to use to finish the piece.
