Plywood is a very versatile material that can be used for many things. It’s durable, strong, and affordable, making it the perfect option for any project you might have in mind. However, plywood requires protection to keep it from deteriorating over time. To help you find the best varnish for plywood on the market today, we researched all of your options and narrowed them down to our top 8 favorites.
Summary of The Best Varnish for Plywood
Why Apply Varnish on Plywood?
Varnish protects plywood by forming a seal over the surface. This not only minimizes deterioration but also helps to prevent rot and mold growth on your project’s exterior. Varnish is nothing more than an impenetrable shield that won’t let anything get in or out of it; this prevents water damage while simultaneously preventing anything else from wreaking havoc on your plywood.
Types of Varnish
Varnish is available in two different forms; oil-based and water-based varnishes are the most common for woodworking projects, but you can even find latex options that work great too! No matter which sort of finish you choose, make sure to apply it correctly so your project looks its absolute best.
1.Oil-Based Varnish
Oil-based varnish is the most common type of wood finish in use today. It contains a mixture of alkyd and oil, which helps it to stand up against weathering while also guaranteeing easy application with little risk of runs or sags. Oil-based finishes need about 30 days to fully cure before you can apply another coat, but they are very durable thanks to their alkyd base. This type of finish is generally pretty affordable and its easy application makes it great for beginners or DIY projects around your home!
2. Water-Based Varnish
This varnish is a more environmentally friendly option that contains water instead of oil. It still offers the same durability and finishes that oil-based varnish does, but it’s much easier to apply. It also dries in just a few hours instead of 30 days, which makes this an excellent choice for your immediate needs! Water-based finishes are incredibly versatile and can be applied on any surface with great results.
3. Latex Varnish
Latex varnish is a great option if you’re looking for something that’s easier to apply, but can’t afford the wait time of water-based or oil-based options. It easily glides onto your project with almost no risk of runs or sags and dries in only 15 minutes! This type of finish comes in either a satin or gloss finish, so it’s perfect for any project.
Before Applying Varnish…
No matter which varnish you choose to go with, make sure your plywood has been sanded down and is free of dust particles before applying the first coat! This will ensure that the surface is as smooth as possible and that the finish is applied evenly. Also, make sure to use very fine grit sandpaper for this process so you don’t leave any scratches on your plywood’s surface.
Can You Clear Coat Plywood?
Yes, but it is not recommended! The clear coating does offer extra protection against scratches and dings on your project’s surface. However, this finish doesn’t allow the wood grain to show through like other types of varnish do; instead, it completely blocks out all grain patterns which makes clear coat an unattractive option for most DIYers.
Things to Consider When Choosing the Best Varnish for Plywood
1. Price
This may sound like a pretty obvious factor, but it is definitely something to consider when you’re choosing the best varnish for plywood. Check out your options and compare prices between brands before making any final decisions; this will help you find the perfect finish that won’t break the bank.
2. Ease of Application
When you’re looking for the best varnish, make sure it’s something that is easy to apply! Water-based and oil-based finishes are typically much more forgiving than latex options. Some brands even offer spray-on applications if you don’t want to deal with a brush or rollers.
3. Application
Different types of varnish are targeted for different uses. You can even find specific brands that are designed to be used on one surface but not another, so make sure you know what type of finish your project needs before making a final decision! For example, water-based finishes work well in humid climates and oil-based varieties work best for heavy-duty projects.
4. Weather Resistance
No matter what type of finish you choose, make sure it offers some form of protection against the elements. If your project will be sitting outside for an extended period of time, then a more weather-resistant option may be necessary to prevent cracking or fading! Some finishes are even rated as being UV resistant so that they don’t turn orange on your project over time.
How to Apply Varnish on Plywood In 6 Easy Steps
Step 1
Make sure your plywood is free of dust, dirt, or fingerprints. Then sand down the surface with medium-grade sandpaper before applying any varnish to avoid scratches in your finish!
Step 2
Apply a coat of primer onto your project using an angled brush. This will help smooth out any coarse areas and ensure that the varnish goes on evenly!
Step 3
Apply your first coat of finish to the project and allow it to dry for 30 minutes. If you’re using a water-based stain, make sure this is applied in thin coats so it doesn’t bubble up or drip onto any areas where it isn’t supposed to be.
Step 4
Apply a second coat of varnish to your project and allow it to dry for at least an hour before touching anything! If you’re using oil-based finishes, make sure this is applied in thin coats as well so the surface isn’t too shiny or tacky when complete.
Step 5
After your second coat of varnish has dried, lightly sand the surface with fine-grit sandpaper until it is smooth. Then apply a third and final layer to seal everything in! The more coats you apply, the harder your finish will be so keep applying thin layers if you want something that’s durable but also easy to repair.
Step 6
After your last coat has dried, remove any dust or debris from the surface of your project with a tack cloth. Then enjoy knowing that you have created an attractive finish on your plywood.
