Lately, I’ve been really conscious about reducing waste and putting effort into repairing things on my own. I have learned that a little bit of creativity and effort goes a long way.

This prompted me to write a complete guide to waterproofing a gazebo canopy. You can now give your old but gold gazebo a new lease on life. Take a look! 

Complete Guide: How To Waterproof Gazebo Canopy

Years have gone by, and your once water-resistant canopy is now leaking from the top and seams. 

What to do? Here are your options: 

  1. Use a waterproof spray on the gazebo fabric 
  2. Seal the seams of the canopy with silicone 

You can find in-depth tutorials for each method below. If none of the methods work for your situation, you can find the right replacement canopy by clicking here

What You Will Need To Waterproof Gazebo Fabric With Spray

  1. Waterproof spray bottle 
  2. Ladder
  3. Tarp 
  4. Broom 
  5. Garden hose or power washer

How To Waterproof Gazebo Canopy With Waterproof Spray

Pick A Sunny Day

Pick a sunny day for this job. You will have to wash off the canopy with a hose and let it dry in the sun. The waterproof spray will also dry quicker in warm weather conditions. 

Make sure you are not working on a windy day, either. The wind will blow away the waterproof spray, which will result in an uneven application. 

Take Off The Canopy 

With the help of a ladder, undo the Velcro straps or snaps to remove the canopy from the gazebo frame. 

If the canvas is covering the posts of the gazebo, unhook it first before proceeding to the top. The sides can be waterproofed, as well, to achieve full protection.  

Clean The Canopy

Lay the tarp on the ground and spread the gazebo canopy on top of it. The tarp will protect the gazebo fabric from dirt and sharp stones.

Wash down the whole canopy using a hose or a power washer. Use a broom to scrub off any stubborn stains and wring out excess water from the canopy when you are done. 

Flip the canopy to the other side and repeat the whole process again. 

Leave The Canopy To Dry

Leave the canopy to dry in the sun for as many hours as needed. Flip the canvas halfway through the process to dry the other side, as well. 

This is why it is important to work on a sunny day. If it is sunny enough, the canvas will dry within a couple of hours. No overnight drying!   

Treat Any Rust (Optional)

While you are waiting for the canopy to dry, you can inspect the metal gazebo frame for rust

If you notice any rust, sand it down with sandpaper and apply a light coat of BlackShell rust inhibitor paint  on the affected area. Let the inhibitor dry before putting the canopy back on the frame. 

Apply The Waterproof Spray

First, protect yourself with a face mask and restrict children and pets from the work area:

Spray the gazebo fabric with the waterproof spray following the instructions provided on the spray can. 

Shake the can, and start spraying at a 45°angle. Work in sections, starting from one corner and going to the other. Move constantly, so the treatment is spread lightly and evenly. Once you have covered the whole surface, you can start applying the second coat

Let the treated side dry completely before working on the bottom side. 

You can buy a waterproof spray on Amazon or at your local hardware store. Here are some recommended sprays:

  1. Kiwi Camp Dry Water Repellent 
  2. Scotchgard Water and Sun Shield 
  3. Star Brite Waterproofing Spray 

Put The Canopy Back On The Gazebo Frame

Once the canopy is completely dry, you can reattach it to the gazebo frame. Get your family members to help you out. Use a ladder to gain better access to the gazebo roof. 

Congratulations! You have successfully waterproofed your gazebo canopy. 

What You Will Need To Waterproof Gazebo Canopy Seams

  1. Odorless mineral spirits
  2. Mixing container
  3. Brush
  4. Popsicle stick 
  5. 100% clear silicone caulk

How To Waterproof Gazebo Canopy Seams 

Make You Own Seam Sealer 

In a glass mixing container, add equal parts of 100% clear silicone caulk  and odorless mineral spirits . Use a wooden Popsicle stick to mix both ingredients into a homogenous paste.  

Or, you can also buy a pre-made seam sealer on Amazon:

  1. Gear Aid Seam Grip FC 
  2. Gear Aid Seam Grip SIL 

Apply Seam Sealer

With a small, hard bristle paintbrush, apply the seam sealer on the seams of the gazebo canopy. Do it as neatly as you can, so you won’t have to wipe up any drips. Leave the sealer to dry for a couple of hours, and you are done! 

FAQ: Answered

Can Gazebos Be Used In Rain?

Only waterproof and water-resistant gazebos can be used in the rain. If the gazebo fabric doesn’t have a density of 190+ grams per square meter, it won’t handle heavier downpours, only light drizzles and showers. Gazebo canopies that are made of lined polyester or are PU-treated are the best for rainy days.

Is Polyester Gazebo Waterproof?

Polyester gazebos are not necessarily waterproof. Gazebo canopies that are made of thin polyester absorb small amounts of water, if they’re not lined with an extra PVC layer or treated with waterproofing chemicals. PU (polyurethane) treated polyester has amazing waterproofing qualities to it.

Does Waterproof Spray Smell?

Yes, most waterproofing sprays have an unpleasant smell of silicone and chemicals. This is why it is important to waterproof your shoes, clothes, and backpacks outdoors, away from children and pets. Wear a face mask to minimize the odor. The smell should vanish after the spray has completely dried on the fabric.

How Many Coats Of The Spray Should I Use?

Apply at least two coats of waterproofing spray on the fabric to get the best results. Follow the instructions provided on the spray bottle, just to be sure. Let the treated fabric dry for 24 hours or more in a well-ventilated area to minimize the odor.
