Polyurethanes are some of the best wood finishes that you can find in the market today. They add beauty and lustrous look to wooden surfaces such as wooden deck floors, bar table tops, kitchen cabinets, etc. One typical way of applying polyurethane is by use of brush, but can you apply polyurethane with a roller?

1. Natural-bristle brushes made with animal hairs are used for applying oil base paints, varnishes, shellac, polyurethane and other oil base finishes. The natural 'flagging' (splitting or fuzzy tips) of these brushes creates split ends in the bristles that hold more paint and help assure a smooth paint release and finish.
2. Cleaning Oil-Based Polyurethane from Paint Brush Oil-based Polyurethane is the biggest challenge, but it is also treatable if you use a paint thinner or white spirit in the right quantity. After soaking in the solution, a good massage of the brush can help soften the hardened polyurethane.

Yes, you can use a roller to apply polyurethane finish on a floor and other wooden surfaces. Polyurethane tends to dry faster, and you can use a paint roller or a brush for application. If you use a roller to apply the polyurethane, you get to eliminate possible brush strokes and lines; it also helps to minimize the chances of over-application of the finish.

Rollers do more than removing brush strokes from your wooden surfaces like floors; they also speed up the work as they cover large spaces in not time.

What Kind of Roller do You Use for Polyurethane?

When it comes to the application of polyurethane, most people find it challenging to prevent dust as well as lint from mixing with the final surface finish. Using short lambswool paint rollers or a fiber paint roller, you will get a very smooth finish on your wooden floor.

Can You Put Too Many Coats of Polyurethane?

No! Putting too many coats of polyurethane on the surface of your wooden floor, for example, is likely to make the surface bulge unless you apply it to both sides of the wood as you’d expect, wood breath. So if there is moisture that is exhausted deferentially on one side of the wood would cause the bulging.

How Many Coats of Polyurethane Should I Use?

Apply up to 3 coats of Polyurethane on your wooden floor would be enough to get the job done, especially if you are finishing your surface using an oil-based poly product. During the application process, ensure that you mix polyurethane with the mineral spirits for the very first coat. This coat acts more like a sealer and the barrier between the wood and the oil-based finish that you are using. You need to use a bristle brush to apply this coat.

How to Apply Polyurethane Using a Roller

Step One

Have your latex gloves as well as nose mask on for protection against contact and inhaling of polyurethane chemicals. Add 2 cups of mineral spirits to a paint pan. Add your polyurethane formula in another paint pan next to the one containing the mineral spirits and closer to the surface that you intend to coat.

Step Two

Slowly put the paint roller in the pan containing the mineral spirits and allow the surface of the roller to dampen thoroughly. Shake off any excess mineral spirits so that it is not dripping. The mineral spirits help with the application of polyurethane.

Step Three

Put the same paint roller with the mineral spirits inside the pan of polyurethane and allow the roller to dampen.

Step Four

Roll the polyurethane over the surface of the wood floor that you need to coat. Quickly roll the material over the surface until there is no more polyurethane on the roller.

Step Five

If you have not completely covered the surface with the first coat, then repeat steps 2 through 4 so that you finish the application of the first coat. Allow the polyurethane enough time to dry, paying close attention to the manufacturer’s recommendation on the label.

Step Six

Using a 280-grit or high sandpaper, sand the surface where you are applying the polyurethane to roughen it up in preparation for the second coat of the poly product. Dip a soft cotton clothing into the mineral spirits to dampen it, wring out the excess moneral spirit and use the piece of cloth to wipe the surface to clear it off any loose sand dust.

Step Seven

Once you are through with the application of the first coat, dip the paint roller inside the pan of mineral spirits to dampen it entirely. Shake off any excess mineral spirits. Put your paint roller inside a freezer bag and allow the pan to dry.

Step Eight

For the application of additional coats of polyurethane, ensure that you repeat the steps 2 through 7.

The Clean Up

First Step

Use hot running water to wash your paint roller so that you remove any remaining parts of the polyurethane as well as the mineral spirits off the roller.

Second Step

Remove the dried substances from the pan that contained the mineral spirits; you can use a flathead screwdriver to do so. Follow this by washing the pan using hot running water. Alternatively, you can choose to dispose of the container in your trash bin.

Third Step

In case some polyurethane remains on the paint pan after you are through with all your coat, consider transferring them into a separate can and close the lid tightly. You can then dispose of the pan in your trash bin. Remember not to return the excess polyurethane into the original container as it will make the whole solution thin.

Fourth Step

Using hot running water, wash the pan that contained the poly formula. You won’t need the pan any time soon; you might consider throwing the pan inside your trash bin.

Fifth Step

As you might need your tools sooner or later, you need to dry the paint roller as well as the pans using as soft cotton cloth and have them kept in your store or the garage for future use.

Advantages of Using Paint Roller

• Using a paint roller ensures coverage of a broad surface area of application. A single pass of a paint roller equals several hundreds of brush strokes.
• The roller does an excellent job of covering the surface evenly regardless of whether or not the surfaces were initially prepared.
• Unlike brushes, paint rollers are designed to work effectively with a good number of modern finishing materials, among them, liquid decorative plaster.
• Paint rollers do not leave visible smears or strokes on the working surface.

Disadvantages of Paint Roller

• A quality paint roller costs a lot more than a paintbrush. Even so, if you can buy a replacement cover, then you will have the roller as a valuable tool in the long run.
• The paint rollers are poor when it comes to the painting of joints, curves, and corners. It means you will need a brush in such cases.

Conclusion

Polyurethane does an excellent job when it comes to adding beauty as well as protection to your wooden floors and other surfaces. That is pretty clear to all now, right? Question though is:

Can You Apply Polyurethane With A Roller?

Yes, you can. Paint rollers do the best job, especially if you are looking to apply polyurethane over large surfaces such as wooden floors. When it comes to speed and saving time, paint rollers work multiple times faster than other application methods like brushes. One shortcoming though, is that rollers are not effective on corners and curves and that the only point where the brush does better.

We believe that we have provided you some useful tips regarding the use of paint rollers in the application of polyurethane. Kindly share with us what you think about this post.

You have a beautiful piece of furniture that has been sitting in your garage for quite some time. Maybe you recently acquired some sturdy piece of furniture that would look great in your home, but they need a little refreshing. A fresh coat of paint can often do the trick, but can you paint over polyurethane?

It seems like this should be a relatively simply straightforward answer. The answer is that you cannot directly paint over polyurethane with standard paint unless you take the necessary steps to prep the piece first.

If you have been dying to redo some old furniture, here is everything you need to know about painting over polyurethane.

What Happens If You Paint Over Polyurethane?

If you choose to paint over polyurethane without prepping, your paint is likely to peel right off. It won’t take much to scrape the paint off the surface. Most people find that it slides right off when they drag a simple fingernail across the surface of their paint.

Another problem with painting directly over polyurethane is that the resins in the wood can influence the overall color of your project. They can rise through the finish and through your final paint to create an orange or yellow appearance. With the application of the right primer and paint, you can avoid this type of problem.

How do you properly prepare your piece to accept a new coat of paint? Here are the steps that you need to follow to get the job done right.

Sanding the Surface

Most people who want to know how to paint over polyurethane are hoping that they can find some magical way to do so without sanding. Putting forth a little elbow grease can really work up a sweat and create quite a mess. Unfortunately, you really should invest some time into sanding a piece of furniture before you paint over the polyurethane finish.

Even if you just want to stain the wood a new color instead of painting it, you will need to sand away the thick yellow coat of polyurethane.

Keep in mind that it may take several passes with different types of grit. A heavy grit sandpaper should be used first to really rough up the surface and get off as much of the polyurethane as possible. You can use progressively lighter grits to get the wood to a consistent, smooth surface that is free from any major scratches that could have been caused by the heavy grit paper.

In the end, you should be left with a clean piece of unfinished wood.

You can use a palm sander to take some of the labor-intensive work out of this simple task. However, you won’t be able to get it into fine grooves and oddly shaped areas like table legs or spindles. For these types of situations, traditional handheld sandpaper is still going to be your very best friend.

Applying a Coat of Deglosser

Can you paint over polyurethane without sanding it first? Many people would argue that sanding is the only real way to go when potentially painting over top of polyurethane. They do not realize that there may indeed be another option. Applying a coat of deglosser, also known as liquid sandpaper, can work in much the same way as sandpaper but without the need for all the sweat.

What Kind Of Brush Do You Use For Polyurethane

It etches the varnish and provides a new texture for the paint to adhere to. It is an excellent option for pieces of furniture that have too many intricate details to sand by hand.

Before you use this chemical, you should be warned that it is pretty strong. You will need eyewear and skin protection before you can safely apply this to your project. Always make sure you are working in an area with good ventilation so that you do not risk damaging your lungs or giving yourself a headache from the fumes.

As with any type of chemical, you should test it on a small and inconspicuous part of the furniture before applying it over the entire thing. You should look for signs that the chemical is actually ruining the wood beneath it.

How do you apply deglosser? The answer is simple. Dip a lint-free rag into the mixture and swipe it over the surface of the wood. You don’t have to work hard to rub it in or rinse it off. Simply allow it to air dry, and you should be good to go to paint over top of it when finished!

Always Use a Primer

A thin coat of bonding primer is going to be an essential ingredient to painting over polyurethane. Applying a good quality primer can help to prevent tannins from bleeding through your paint and ruining the overall color. Primer should be applied with thick and even strokes, taking care not to have splotches of thick patches anywhere on the project.

Let this first coat dry and then gently sand it. Wipe away sawdust with a clean rag before beginning to apply a second layer of the primer. Allow the piece of furniture to dry overnight and then sand it again in the morning. The goal is not to sand all the way through the primer. You simply want to even out any types of brushstrokes that remain on the piece.

If you do not sand the primer appropriately, you might have blotchy stains on the piece when you apply the final coat of paint.

Primers can often be thick and difficult to clean up. Make sure that you have plenty of mineral spirits on hand to clean up your brushes and any type of mess that you create.

Applying the Paint

Once you have taken all of these steps, then you are finally ready to apply the actual paint to your project. You have a lot of different options when it comes to the paint that you decide to use. Some people prefer to use an all-in-one option because they believe it will save them from having to apply both primer and paint. Unfortunately, this may not be the best option for your project.

These one-step solutions are often very expensive, and they will not provide a lasting finish. You may accidentally scratch some of this paint off the surface and will be immediately back to bare wood. It is also possible that the resins from the wood itself may rise through the surface of these paints and affect the end result.

Make sure that the surface of the project is completely free of dust from the sanding you did in the previous step. Wipe it down with a lint-free cloth. Then, you can apply the first topcoat of paint. Let it dry overnight and then apply a second coat in the morning.

Keep in mind that your paint still needs to cure even though it is technically dry. You should wait a minimum of 72 hours before you begin to decorate and place objects on top of it. If you can wait a little longer than this, it is really ideal.

Using Chalk Paint

Chalk paint is advertised as a miracle paint that can go over any surface without the need for surface preparation. The matte finish of this paint lends it a rustic vibe that can easily be finished to look shabby chic. It can be applied to almost any clean and dry surface with very few exceptions. Even if the piece has had paint applied to it previously, chalk paint can go right over the surface without the need for any prep work besides cleaning.

Theoretically, you should be able to apply chalk paint over top of your polyurethane furniture. Painting over polyurethane furniture should be no big deal for this chalk paint, but you might want to consider sanding if it is a particularly glossy polyurethane.

Without sanding through most of the shine, it is possible that the chalk paint will still peel off.

What about the other way around?

Can you put polyurethane over chalk paint?

The answer is definitely a Yes. In fact, there are some situations where you would definitely want to use polyurethane instead of the traditional wax finish. Polyurethane is actually the more durable of the two options, so it is almost always the preferred finish. If your piece of furniture will be coming into contact with lots of moisture or wear and tear, then polyurethane is the safest option for the finish type.

Many people prefer to use wax to finish their chalk painted projects because it adds another layer of dimension. Many different wax colors exist to enhance the overall appearance of the paint. Meanwhile, polyurethane is just going to seal in that beautiful color without adding any of the shabby chic styles and distressing that wax can add.
