Types of Sealants Used to Seal Birch Plywood
1. Oil-Based Sealer
Oil-based sealers are popular for woodworking not only because of their affordability but also because they offer a lot of versatility. You can use it on both hard and softwoods including all types of plywood like birch plywood. It has good UV stability so you can even apply an oil-based sealant to your project outdoors in sunny conditions. Oil-based sealants are somewhat easy to apply but expect the process to take a little bit longer due to their long dry times.
Types of Oil-Based Sealers.
- Penetrating oil finishes like Watco Danish Oil. These typically need to be burnished after application and will not offer any UV resistance or water protection.
- Tung oils can provide a hard-wearing finish that also has UV resistance.
- Danish oil is made from tung oils suspended in varnish or solvent. This type of sealer is typically mixed with mineral spirits to thin the product before application and it will need to be burnished after drying to provide a hard-wearing finish.
Tips for Applying Oil-Based Sealant
- Apply the oil-based sealer with a brush or rag, but you will need plenty of time before the product dries completely and this can take several hours depending on how thickly it is applied. Oil-based sealers should not be used in direct
- When applying the oil-based sealant to birch plywood, there are a few important things you should keep in mind. Always apply the product evenly and avoid over-saturating your project as it may cause complications with drying time or leave unwanted streaks of excess sealer on your wood.

Pros
Oil-based sealers have many advantages including;
- It is economical and offers good UV resistance so it can be used outside without significant degradation.
- It is fairly easy to apply with a brush or rag and it provides excellent coverage on surfaces due to its low surface tension.
Cons
Oil-based sealers have some disadvantages including;
- The drying time can be very long, so you need plenty of patience before moving on to the next step in your project.
- The odor can be very strong, so you need to make sure that your work area is well ventilated while using an oil-based sealant.
2. Water-Based Sealer
Water-based sealers are often preferred by both enthusiasts and professional woodworkers because they dry quickly, which makes them convenient to work with. This type of protective coating is also popular for outdoor projects like decks or furniture that will be exposed to the elements. Some water-based finishes may not offer any UV resistance, however, so you’ll need to do your research before choosing the best product for your project.
Types of Water-Based Sealers
1. Polyurethane
Polyurethanes are water-based finishes that can be used to protect both wood and metal surfaces. You can apply them with a brush or rag, but they will need plenty of time to dry before you move on to the next step in your project. Polyurethanes offer excellent UV resistance so it is perfect for outside projects like decks or furniture.
2. Polyacrylic
Another popular type of water-based sealer is polyacrylic, which can be applied with a brush or rag. It typically offers excellent UV resistance and has good durability compared to other varieties of water-based finishes. The drying time for this product tends to be shorter than for oil-based sealers so you will need less patience while waiting for the project to dry.
3. Water-Based Alkyd
This type of water-based sealer is a hybrid product that offers some advantages from both oil and polyacrylic. It will not leave any film on the surface, which means it dries clear so you can see your project as you work on it. Some varieties of Water-based alkyd also offer good UV resistance and durability, but it does depend on the brand manufacturer.
Tips for Applying Water-Based Sealers

- When applying water-based sealant, you must use a brush with synthetic bristles because natural bristles may leave unwanted streaks of excess material on your project.
Pros and Cons of Water-Based Sealants
Pros
There are many benefits associated with using water-based protectors for wood surfaces including:
- Low odor.
- Quick-drying time.
- Convenience.
Cons
- Because water-based sealers are applied with a brush, they can leave streaks of excess material on your project surface if you don’t use the right applicator pad or apply too much pressure when brushing it over the wood.
- It is light and this will lead to the application of multiple coats before achieving the desired color foundation.
Factors Considered When Choosing the Best Sealant.
Before choosing a sealant for birch plywood, there are several factors to consider including:
1. The type of wood you plan on sealing.
Different types of wood require different protective coatings so you must choose the right product before starting your project. For example, Water-based sealants are not suitable for exterior projects because they are not UV resistant.
2. The color of the wood.
Water-based sealants are clear and won’t change the color of your birch plywood, but they can affect how light reflects on its surface if you don’t apply them evenly across the project’s surface. If this happens, then expect to see streaks or spots that show up in different areas of your project.
3. The condition of your wood.
If you’re dealing with rough or torn-up birch plywood, then it’s important to choose a product that will allow for proper sanding and smoothing down the surface before applying the sealant so this won’t be an issue when using water-based products.
4. The durability and maintenance of your project.
If you’re creating a permanent wood surface like an outdoor deck, then it’s important to choose a product that has high durability and will be able to stand up against natural elements such as rain or snow. Water-based sealants offer decent protection but they won’t last forever so make sure this is something that won’t be an issue for your project before starting.
5. Your budget.
Sealants are not cheap products, but the good news is that you can find them for a reasonable price if you’re on a limited budget. Even though water-based sealant offers many benefits over oil or polyacrylic, it’s still recommended to use these superior types of protectors when possible because they offer more protection and durability for your wood surfaces.
6. The color and the finish of your project.
If you’re creating a finished wood surface like an outdoor deck or kitchen cabinets, it’s important to choose a sealant that gives off the same type of appearance as your project because this will ensure everything looks uniform and seamless when finalizing it. If not, then expect some differences in tone between different parts of your project so it’s important to be mindful of this before starting.
