What is the Difference between Sanding and Sealing Wood for Interior Vs. Exterior Projects?
When it comes to working with wood, sanding and sealing are two essential steps that can make a big difference in the final appearance and durability of your project. But do you need to do things differently for interior and exterior projects? The answer is yes.
Sanding: Interior vs. Exterior
Sanding is the process of removing small particles and imperfections from the wood surface. For interior projects, you can usually opt for a lower-grit sandpaper (around 120-150) to create a smooth finish. However, for exterior projects, you’ll need to use a higher-grit sandpaper (220-240) to ensure the wood is protected from the elements. This is because high-grit sandpaper is better at removing tiny particles and debris that can deteriorate the wood over time.
Sealing: Interior vs. Exterior
Sealing is the process of applying a protective coating to the wood to prevent it from drying out, cracking, or decaying. For interior projects, you can usually use a water-based polyurethane or varnish that is designed for indoor use. These types of sealers are generally easier to clean up and less toxic than oil-based options.
Exterior projects, on the other hand, require a more durable and weather-resistant sealer. Look for products that are specifically labeled as “exterior-grade” or “outdoor-use.” These types of sealers are designed to withstand UV rays, rain, snow, and extreme temperatures.
Additional Tips
- Use a primer if you’re painting over the wood to ensure better adhesion and coverage.
- Choose the right type of wood sealer based on the type of wood you’re working with. Different types of wood require different types of sealers.
- Always read the instructions and safety precautions on the sandpaper and sealer packaging.
- Test a small, inconspicuous area of the wood before applying the sealer to ensure it doesn’t affect the color or texture.
Can I Use a Sanding Sealer on Wood Surfaces with Open Pores?
If you’re working on a wood project and wondering if you can use a sanding sealer on surfaces with open pores, the answer is yes, but with some considerations.
What are Open Pores?
Open pores are tiny holes or channels in the wood’s surface that can be caused by natural imperfections or the woodworking process itself. These pores can be a bit of a challenge when it comes to applying a sanding sealer, as they can absorb a lot of the sealer and make it difficult for the sealer to adhere evenly.
Can You Use a Sanding Sealer with Open Pores?
- Clean the surface : Make sure the wood surface is clean and free of dust, dirt, or other debris that could interfere with the sealer’s adhesion.
- Fill the pores : Use a wood filler or a wood pore filler to fill the open pores. This will help create a smoother surface for the sealer to adhere to.
- Sand the surface : Lightly sand the surface to create a rough texture for the sealer to grip onto. Start with a coarse grit sandpaper (about 120-150) and gradually move to a finer grit (220-240) for a more even finish.
- Apply the sealer : Apply the sanding sealer according to the manufacturer’s instructions. Typically, this involves applying a thin, even layer to the surface and letting it dry before sanding.
Additional Tips
- Use the right sealer : Choose a sanding sealer that is specifically designed for wood and can handle the porosity of your surface.
- Don’t overdo it : Avoid applying too much sealer, as this can create a thick, uneven layer that’s difficult to sand off.
What is the Process for Applying a Coat of Sealer on Wood Projects?
Wood projects can be beautiful, but they require proper care to maintain their quality and longevity. Apply a coat of sealer to protect your wood projects from damage caused by moisture, sun exposure, and wear and tear.

Is Water-based or Oil-based Sealer Better for Wood Surfaces?
When it comes to sealing wood surfaces, choosing the right type of sealer can be a daunting task. Two popular options are water-based and oil-based sealers. But which one is better?
Water-Based Sealers
- Pros:
- Less toxic and hazardous to health
- Easy to clean up with soap and water
- Fast-drying and low-odor
- Suitable for interior and exterior use
- Cons:
- May not provide long-lasting protection
- Can leave a matte finish
- May not be suitable for wood surfaces prone to moisture
Oil-Based Sealers
- Pros:
- Provides long-lasting protection against wear and tear
- Can enhance the natural beauty of the wood
- Suitable for wood surfaces prone to moisture
- Can provide a glossy finish
- Cons:
