What Is Sherwin Williams Conversion Varnish And Why Is It Problematic For Some Woodworkers?
Sherwin Williams Conversion Varnish is a type of varnish that is designed to convert the tannin in wood into a polymer. It is useful for preventing staining and discoloration of the wood.
However, some woodworkers have reported problems with this varnish, such as it lifting and the finish separating from the surface.
When considering using Sherwin Williams Conversion Varnish, be aware of these potential issues. This can be a major problem when working on a project where appearance is important.
In addition, Sherwin Williams Conversion Varnish can be more expensive than other types of varnish. When considering using this type of varnish, you need to weigh the pros and cons before making a decision. Conversion varnish is not right for every project, but it can be a great option for some woodworking projects.
The Most Common Problems With Sherwin Williams Conversion Varnish
Conversion varnish is a type of finish that is often used on wood surfaces. It is applied as a topcoat over stain or paint, and it provides a hard, durable surface that can resist scratches and stains. However, conversion varnish can also be susceptible to peeling and lifting if it is not applied correctly.
Below are some of the most common problems that can occur with Sherwin Williams conversion varnish:
- The finish lifts and separates from the surface. This is usually caused by the incorrect application, such as not allowing enough time for the primer to dry before applying the varnish. It can also be caused by using a brush that is too stiff, or by using too much pressure when rolling or brushing the varnish on.
- The finish is blotchy or uneven. This can be caused by applying the varnish too thickly, or by not stirring it properly before application. It can also be caused by not allowing enough time for each coat to dry before applying the next coat.
- The finish is cloudy or dull. This can be caused by using a low-quality varnish, or by not allowing the final coat to dry completely before applying a topcoat. It can also be caused by applying the varnish in humid conditions.
- The finish creates bubbling or craters. Bubbling is when the conversion varnish expands and creates little bubbles in the finish. This can be caused by using a brush that is too stiff, or by not allowing enough time for the varnish to dry before applying a topcoat. It can also be caused by applying the varnish in humid conditions.
- The conversion varnish doesn’t play well with others. If you try to mix it with another finish, or even just put a topcoat of lacquer over it, you’ll probably have problems. It’s best to just use conversion varnish by itself.

How To Fix These Problems
Some problems can occur when using a Sherwin Williams Conversion Varnish. Today, we will be discussing these problems and how to fix them. Fortunately, there are things that you can do to fix these problems.
- The first problem that can occur is that the varnish can lift. This happens when the finish separates from the surface. To fix this, you will need to allow the primer to dry before applying the varnish. You should also make sure you are using the correct type of primer.
- Another problem that can occur is that the varnish can be blotchy or uneven. Make sure to apply thin, even coats to avoid this problem. If the varnish is still uneven, you can try using a different type of brush. Sometimes, brushes can leave behind streaks or brush marks. You may also need to allow enough time for the varnish to dry completely before applying a second coat.
- The third problem is when the finish is cloudy or dull. To fix this, you may need to sand the surface before applying the varnish. This will help to create a smooth, even surface. It is also important that you wait until the varnish is completely dry before applying a second coat.
- The fourth problem is when the finish creates bubbling or crates. Because this can be caused by a brush that is too stiff, try using a different brush. You may also need to thin the varnish before applying it. This will help to prevent bubbling and cratering. You may also need to wait for the varnish to dry completely before applying a second coat and avoid applying the varnish in humid conditions.
- The fifth and final problem is when the finish does not play well with others. This can happen when the varnish is not compatible with the paint or primer that you are using. Make sure to check compatibility before applying the varnish. You may also need to use a different type of paint or primer.
These are just a few of the problems that can occur when using Sherwin Williams Conversion Varnish. Fortunately, there are things that you can do to fix these problems. By following the tips above, you should be able to get great results with your next project.

- Make sure you mix the resin and hardeners thoroughly before applying them to the surface.
- Apply the mixture evenly, using a brush or roller.
- Avoid applying the mixture in direct sunlight or very humid conditions.

By following these tips, you can help ensure that your conversion varnish finish will be smooth and problem-free. If you do experience any problems, be sure to consult with a professional painter or finisher for assistance.
Can You Buff Out Conversion Varnish?
You can buff out conversion varnish after it’s cured using wet/dry automotive sandpaper. The process is similar to buffing out a car’s paint job. You’ll want to start with low grit sandpaper and work your way up to a high grit. Remember to always sand in the direction of the grain.
How Long Does It Take For Conversion Varnish To Cure?
Conversion varnishes are 85% cured within about two days of their application. It takes about three to four weeks to achieve a cure that is worthy of topcoat protection.
However, both types of finishes continue to harden and improve over time. For best results, allow conversion varnish and pre-cat lacquer to cure for at least 23 days before subjecting them to heavy use or wear.
Can You Apply Polyurethane Over Conversion Varnish?
Yes, you can apply polyurethane over conversion varnish without damaging the finish. However, there are some things you need to keep in mind to get the best results.
Conversion varnish is a type of clear coat that is typically used on wood surfaces. It is known for its durability and resistance to wear and tear. Polyurethane is also a type of clear coat, but it is thinner and more durable than conversion varnish.
When applying polyurethane over conversion varnish, you need to make sure the surface is clean and free of any dirt or debris. You also need to sand the surface lightly to rough it up a bit and allow the polyurethane to adhere better.
Once you have prepped the surface, you can apply the polyurethane according to the manufacturer’s instructions. You will likely need to apply several coats to get the best results.
Conversion varnish is great for those who are looking for a durable and long-lasting finish. However, you need to keep in mind that you will need to take extra care when prepping the surface before applying polyurethane.
By following these simple steps, you can ensure that your finish will last for years to come.
