Why Seal an Outdoor Wood Table?

Wood is a natural material that is prone to wear and tear, especially when exposed to the elements. Without proper protection, your outdoor wood table can develop discoloration, cracks, and warping due to moisture, sunlight, and temperature changes. A sealant acts as a barrier between the wood and these external factors, preventing damage and increasing the lifespan of your table. It also enhances the natural beauty of the wood, making it look more vibrant and polished.

Supplies You Will Need to Seal an Outdoor Wood Table

1. Sandpaper (150-220 grit)

2. Soft-bristled brush

3. Clean cloth

4. Wood cleaner or mild soap and water

5. Mineral spirits or paint thinner (if needed)

6. Exterior wood sealant/stain (oil-based or water-based)

7. Paint tray and roller/brushes

Step-by-step Guidelines on How to Seal an Outdoor Wood Table

Step 1: Prepare the Wood Surface

The first step is to prepare the surface of your outdoor wood table. This includes removing any dirt, dust, or debris using a soft-bristled brush and cleaning it with a mild wood cleaner or soap and water. For tougher stains or discoloration, you can use mineral spirits or paint thinner, but make sure to follow the instructions on the product carefully. Once the surface is clean, let it dry completely before moving on to the next step.

Step 2: Sand the Wood

Sanding helps to smooth out any rough spots and opens up the pores of the wood, allowing for better absorption of the sealant. Use a fine-grit sandpaper (150-220 grit) to gently sand the entire surface of the table. Make sure to sand in the direction of the wood grain and wipe away any dust or debris with a clean cloth.

Step 3: Choose the Right Sealant

When it comes to choosing a sealant for your outdoor wood table, there are two main options – oil-based or water-based. Oil-based sealants penetrate deeper into the wood, providing longer-lasting protection and enhancing the natural color of the wood. On the other hand, water-based sealants offer better UV resistance and are easier to clean up with soap and water. Consider your specific needs and preferences before deciding which type of sealant to use.

Step 4: Apply the Sealant

Now it’s time to apply the sealant onto your outdoor wood table. Start by stirring the sealant thoroughly and pouring it into a paint tray. Use a roller or brush to apply an even coat of sealant onto the surface of the table, following the direction of the wood grain. Allow the first coat to dry completely before applying a second coat for added protection.

Step 5: Let it Dry 

After applying the final coat of sealant, it’s important to let your outdoor wood table dry completely before using it. This can take anywhere from 24 to 48 hours depending on the type of sealant used and weather conditions. Make sure to follow the instructions on the product for specific drying times.

Following these simple steps will help you properly seal your outdoor wood table and ensure its longevity. But remember, maintenance is key when it comes to upkeeping a sealed wood surface. Regularly clean and reapply the sealant every few years or as needed to keep your table looking beautiful and protected for years to come. Happy sealing!
