How to Waterproof Wood Siding

In this blog post, we’ll be exploring exactly how to waterproof wood siding so that you can do it yourself – quickly, easily, and effectively.

10 Steps on How to Waterproof Wood Siding

1. Choose the Right Sealant:

When it comes to waterproofing wood siding, you have to start by choosing the right sealant for your project. There are many different types of sealants available on the market, including oil-based and water-based options. Oil-based sealants are better at repelling water, while their water-based counterparts are more environmentally friendly. Choosing the right sealant for your project depends on factors such as climate, budget, and personal preference.

2. Prepare the Wood Siding:

Before you start applying any sealant, it’s essential to prepare the wood siding properly. Start by removing any dirt or debris from the surface using a stiff-bristled brush. If there are any stains or discoloration, you may need to use a mild detergent and water solution to clean the wood siding thoroughly. Once the surface is clean and dry, sand down any rough or splintered areas to create a smooth surface for the sealant to adhere to.

3. Apply a Water Repellent:

Once the wood siding is prepared, it’s time to apply a water repellent. This will help prevent water from seeping into the wood and causing damage. You can choose a clear or pigmented water repellent, depending on your preference. Clear repellents allow the natural grain of the wood to show through, while pigmented ones add a touch of color to the wood. Make sure to follow the manufacturer’s instructions for application and drying times.

4. Use a Waterproofer:

After the water repellent has dried, it’s time to use a waterproofing product specifically designed for wood siding. These products contain ingredients that penetrate deep into the wood fibers, creating a barrier against moisture. They also often include UV protection to prevent fading and discoloration from sunlight exposure. Using a waterproofer will further enhance the waterproofing of your wood siding.

5. Consider Using Primer:

 Fill in Small Cracks

For maximum protection, you may want to consider using a primer before applying any sealants or waterproofers. Primers provide a strong base for the sealant to adhere to and help extend its lifespan. They also fill in small cracks or imperfections in the wood, ensuring a more even application of the sealant.

6. Pay Attention to Joints and Seams:

When waterproofing wood siding, it’s crucial to pay extra attention to joints and seams where water can easily seep in. Use a caulking gun and high-quality caulk to seal any gaps or cracks between boards, around windows and doors, or at the corners of your house. This will help prevent water from entering these vulnerable areas and causing damage.

7. Apply Multiple Coats:

Applying multiple coats of sealants or waterproofers is an excellent way to ensure maximum protection for your wood siding. After each coat has dried, sand down any raised fibers or rough spots before applying the next layer. This will create a smoother and more even surface for the next coat to adhere to.

8. Consider Using a Wood Preservative:

Preservative

In addition to waterproofing, you may want to consider using a wood preservative on your siding. These products contain fungicides and insecticides that help prevent mold, mildew, and insect damage. They can also provide extra protection against decay and rot. This is especially important for areas with high humidity or moisture levels.

9. Regularly Inspect and Maintain:

Even with proper waterproofing and preservation, it’s essential to regularly inspect and maintain your wood siding. Check for any signs of damage or wear, such as cracks, peeling sealant, or discoloration. Address these issues promptly to prevent further damage and lengthen the lifespan of your wood siding. If necessary, reapply sealant or waterproofers every few years to maintain maximum protection.

10. Reapply Waterproofing as Needed:

Over time, the water-repellent and waterproofing products on your wood siding will wear off and need to be reapplied. How often this needs to be done depends on factors such as climate, exposure to sunlight, and the quality of the original product. Be sure to regularly check for any signs of wear and reapply sealant or waterproofer as needed to maintain the waterproofing of your wood siding.

Following these 10 steps will help you effectively waterproof your wood siding and protect it from the elements for years to come. Remember to always follow the manufacturer’s instructions and safety precautions when working with sealants and other products. With a little effort, you can ensure that your wood siding stays looking beautiful and in top condition. Happy waterproofing!

Precautions Need to Follow for Waterproofing Wood Siding

Wear Protective Gear Such as Gloves
  1. Proper preparation is essential before you start waterproofing your wood siding. Make sure to remove any old coatings, dirt, or mildew from the surface by using a scraper or pressure washer.
  2. Allow the wood to dry completely before applying any waterproofing products. This will ensure that the product adheres properly and provides maximum protection.
  3. Check for any cracks or gaps in the wood siding and seal them with caulk or putty. This will prevent water from seeping into the wood.
  4. Before applying any waterproofing product, make sure to protect nearby areas such as windows, doors, and plants. Cover them with plastic sheets or tape to avoid any accidental damage.
  5. Wear protective gear such as gloves, goggles, and a mask while applying waterproofing products. These products can contain strong chemicals that can irritate the skin, eyes, and respiratory system.
  6. Follow the instructions provided by the manufacturer carefully while applying the waterproofing product. Each product may have different application methods and drying times.
  7. Apply multiple thin coats of waterproofing product instead of one thick coat for better adhesion and coverage. Allow each coat to dry completely before applying the next one.
  8. Once you have finished waterproofing, regularly inspect your wood siding for any signs of damage or wear. Touch up any areas that may have been missed or damaged to maintain the waterproof barrier.

Following these precautions will not only ensure that your wood siding is properly waterproofed but also keep you safe during the process.
