The Difference Between Satin, Semi-Gloss, And Gloss Finishes
There are three common types of polyurethane finishes satin, semi-gloss, and gloss. The type of finish you choose will depend on the look you want to achieve and the level of durability you need.
Satin Finishes:
There is a degree of luster in satin finishes and their glossiness highlights the imperfections on walls such as cracks or poorly patched areas which makes them ideal for busy families with small children or pets. They are also more durable than semi-gloss finishes, so they’re perfect for high-traffic areas like kitchens and bathrooms.
Semi-gloss Finishes
Semi-gloss finishes have a bit more shine as compared to satin and are better at resisting stains and scratches. They’re also easier to clean, so they’re a good choice for areas that see a lot of activity.
Gloss Finishes
Gloss finishes have the highest shine and are the most resistant to stains and scratches. They’re also the easiest to clean, so they’re a good choice for areas that see a lot of activity. However, their high shine can highlight the imperfections on walls such as cracks or poorly patched areas.
If you’re not sure which finish to choose, ask a professional painter or visit your local home improvement store for advice.
Now that you know the difference between the three common types of polyurethane finishes, you can now decide which one is right for your project.

How Do You Fix Thick Polyurethane?
You can fix thick polyurethane by sanding it down and starting over. You’ll need to remove the excess polyurethane, sand the area smooth, and then apply a new coat of polyurethane. It’s important to follow the manufacturer’s instructions when applying polyurethane. If you put it on too thick, you’ll end up with a sticky mess.
If you’re having trouble getting the polyurethane to level out, you can try using a brush or roller designed for applying thick coatings. These products can help you apply an even layer of polyurethane without putting it on too thick. Just be sure to follow the manufacturer’s instructions for the best results.
Should Polyurethane Be Thinned?
You do have the option to thin your polyurethane prior to using it, but you don’t necessarily have to. If you do choose to thin it, use mineral spirits or naphtha. How much you thin it is dependent upon the climate conditions. For example, if it’s hot and humid where you are painting, you will want to thin the polyurethane more than if you were painting in cooler, drier conditions. The general rule of thumb is to add about 20% thinner to the polyurethane prior to applying it.
If you are going to be using a brush to apply the polyurethane, you will want to thin it slightly more than if you were going to use a roller or pad. The reason for this is because brushing on the polyurethane can cause bubbles and brush strokes. Thinning the polyurethane will help to avoid these problems.
One other thing to keep in mind is that thinning the polyurethane will also reduce the amount of protection it provides. So, if you are going to be using the polyurethane in an area that is prone to a lot of wear and tear, you may want to forgo thinning it.
In general, it is best to err on the side of not thinning the polyurethane too much. You can always add more thinner if you find that you need it, but you can’t take it out once it’s been added. So, start with a small amount of thinner and add more as needed.
