7 Steps for How to Waterproof a Pergola
Step 1: Inspect Your Pergola
Before beginning to waterproof your pergola, you must ensure it is structurally sound and free from any defects.
Examine the frame for damage or rot, and check that all beams are securely attached. If there are any loose parts, repair or replace them before continuing.
Step 2: Clean Off Dirt & Debris
Using a hose or pressure washer, use clean water to rinse off the pergola frame and all its components.
This will ensure a good surface for any sealant or paint you use. Make sure to let the wood dry completely before applying any product.
Step 3: Consider Waterproofing Products
Several waterproofing products, such as sealers, paints, and coatings, are on the market. Each has pros and cons, so you should consider which is most appropriate for the job.
Step 4: Prepare & Apply Sealant
Choose the right waterproofing product. Spread it evenly using a brush or roller. Do this in small sections at a time. Make sure you cover all the surfaces, especially cracks, and crevices, which may need more coats of paint.
Step 5: Allow to Dry
Once you’ve finished applying the sealant, let it dry completely before moving on to the next step. Depending on the product used, this may take several hours or days.
Using fine-grit sandpaper, lightly sand the entire pergola to ensure a smooth finish and remove any excess sealant. This will also help create better adhesion for any paint you’ll use in the next step.
Step 6: Paint Pergola
Applying two or more coats of exterior paint to the pergola using a paintbrush or roller. This will provide extra protection from water and weathering. Allow each coat to dry before applying the next one.
Fill in any cracks or joints on the pergola using a silicone-based caulk. This will provide additional waterproofing and help prevent water from seeping through.
Step 7: Apply Stain & Sealer
Apply a wood stain and sealer to the pergola for added protection. When buying something for outside use, get the best quality product. Please read and follow the instructions that come with it carefully.
Now that you’ve completed all the steps, it’s time to enjoy your newly waterproofed pergola. You can confidently rest assured that it is safe from water damage and will last for years.
Safety Tips for Waterproofing Your Pergola

- Ensure you are well-ventilated by opening windows or using an air purifier while working on the project.
- Before beginning work, read and follow the instructions on all products used in the waterproofing process.
- Avoid using flammable materials or solutions when applying sealants or coatings to your pergola.
