Remember, all good things come with their own set of downsides. In the next section, we’ll discuss some of the cons of using Minwax Polyurethane Spray.

The Cons of Using Minwax Polyurethane Spray

While Minwax Polyurethane Spray has many advantages, there are also some downsides to consider. An important factor to note is the drying time. This product takes a full 24 hours to dry, which might not be ideal if you’re working on a project with a tight deadline.

The spray also has a yellow or amber color. Although it can enhance the richness and depth of many wood types, it might not be your best bet if you’re looking for a clear or neutral finish. Here’s our post for the best clear polyurethane spray for wood if you want that clear finish.

Also, compared to its brush on version, Minwax Polyurethane Spray can be a tad more expensive. If you’re working on a large project and need to stay on a tight budget, this cost difference might be a point of consideration. Check out how I used the brush on version in my post about how to strip a kitchen table.

Another aspect to consider is that you need to protect surfaces around your project. The spray, while easy to apply, can get all over if you’re not careful. And this oil based version is not as easy to cleanup.

Lastly, but most importantly, make sure to use it in a well-ventilated area. The fumes from the spray can build up, potentially leading to health hazards if not properly managed.


  • Dries in 24 hours
  • Has a yellow/amber color
  • More expensive than the brush-on version
  • Protect surfaces around where you’re spraying to avoid overspray
  • Use in a well ventilated area to avoid fume buildup

Spraying Minwax Polyurethane

Spraying Minwax Polyurethane is like an art that brings life and beauty to your wooden furniture and projects. It’s all about following a few important steps to create a smooth, even finish. So, let’s take a closer look at how to spray Minwax Polyurethane like a pro!

First things first, let’s get prepared. Start by cleaning off any dust or debris from your project. This creates a smooth finish and a perfect bond between the polyurethane and the wood, with no pesky dust particles getting in the way.

Now, let’s talk about protecting the surrounding area. Grab some drop cloths, painter’s tape, or even old newspapers to prevent any overspray. Trust me, it’s much easier to prevent a mess than to clean it up later!

Safety is always a priority. Make sure to wear a respirator and eye protection when spraying polyurethane. This keeps you safe from any harmful fumes or potential splatters.

Now, for the application part. Shake that can for a good 2 minutes to make sure the polyurethane is thoroughly mixed. This is crucial for getting a smooth and consistent finish.

When you’re ready to spray, start with thin coats and sweep across the surface you’re working on. This technique helps prevent any runs or drips, giving you that flawless finish you’re aiming for.

Give your project some time to dry. Wait at least 30 minutes before applying another coat of polyurethane. For the best results, try to get all your coats done within a 2-hour window.

To create a highly durable finish, make sure to apply at least 3 coats of polyurethane. And remember, patience is key! Let it cure for at least 24 hours after the final coat before putting your project back to regular use.

Now you’re all set to spray Minwax Polyurethane like a pro! Enjoy the process and admire the beautiful results.

Can you use minwax polyurethane over paint?

Yes, and no. You can topcoat chalk paint, mineral paint, acrylic paint, and oil based paint with Minwax polyurethane spray! But, it has a yellow tone, so it’s best to use it only over darker colors of paint.

If you use waterbased paint, make sure the paint dries at least 48 hours before applying this oil based topcoat. Check out this antique pie crust table makeover project where we used milk paint and Minwax polyurethane spray as a topcoat.

Minwax Polycrylic vs. Polyurethane

When comparing Minwax’s Polycrylic and Polyurethane, there are several key differences to keep in mind. The Polycrylic is a waterbased topcoat that dries clear, making it perfect for light colored woods and paint.

It dries faster than its counterpart, the Polyurethane, allowing you to sand in between coats and add multiple coats in less time. Learn more about the pros and cons of Minwax polycrylic in our Minwax Polycrylic Spray post. We also feature it in this best spray polyurethane post.

On the other hand, Polyurethane, being oil based, offers more durability, making it ideal for high traffic areas and outdoor furniture. Here’s our polycrylic vs polyurethane comparison to help you learn more about the difference between the two.

However, it does have a yellow tint and takes longer to dry. Both products are easy to spray, but your project’s specific needs and the look you’re going for will determine the best choice between the two.

Why is my polyurethane finish rough?

So are you struggling with a rough polyurethane finish on your project? Well, there are a few reasons why this may be happening. The first thing to check is the surface you are applying the polyurethane on. If it is already rough, then your finish will also turn out rough.

This also means the paint or stain you used as a base may not have been applied smoothly. Any imperfections in the base coat will show through in the polyurethane finish. So make sure to sand down any rough spots and smooth out the surface before applying both paint and polyurethane.

Another common culprit for a rough finish is dust. Even the smallest specks of dust can create bumps and imperfections in your finish. Before applying the polyurethane, make sure the painted surface is completely clean and dust free. You can use a tack cloth to remove any remaining dust particles.

The way you apply the spray polyurethane may also contribute to a rough finish. Use thin coats and avoid spraying too much in one area. Try using long sweeping motions to apply the polyurethane instead of short bursts.

You can fix a rough polyurethane finish by lightly sanding it down with fine grit sandpaper and then applying another coat of polyurethane. By this time, you should’ve already checked and fixed any surface imperfections, so the new coat of polyurethane should turn out smooth.
