Hey there! I’m one of the folks running a bamboo decking supply business, and I get this question a lot: "How do I treat bamboo decking to prevent mildew?" It’s a great question, and in this blog, I’m gonna share some practical tips based on what we’ve learned over the years. Bamboo Decking
Understanding Mildew and Bamboo Decking
First off, let’s talk about what mildew is. Mildew’s basically a type of fungus that loves damp, warm, and dark places. Bamboo decking, being an organic material, is a prime target. It can grow on the surface of your deck, making it look ugly and also posing a safety risk as it can make the deck slippery.
Bamboo is a cool material. It’s strong, sustainable, and looks really nice. But because it’s made from plants, it’s got natural sugars and starches that mildew just can’t resist. So, if you live in a humid area or if your deck gets a lot of shade and doesn’t dry out quickly after it rains, you’ve got a higher chance of mildew showing up.
Pre – Installation Treatments
When you’re getting ready to install your bamboo decking, there are a few things you can do to give it a fighting chance against mildew.
Pressure – Treatment
One of the best ways is to get pressure – treated bamboo decking. What happens in the pressure – treatment process is that the bamboo is placed in a big chamber, and then a special preservative is forced into the wood under high pressure. This preservative helps to kill any existing fungus and also acts as a deterrent for future mildew growth. It gets deep into the bamboo fibers, making it much more resistant.
We usually recommend pressure – treated bamboo for areas where moisture is a big issue. It might cost a little more upfront, but it can save you a lot of hassle in the long run.
Sealers
Another option is to apply a sealer before installation. Sealers create a protective barrier on the surface of the bamboo. There are different types of sealers out there, like oil – based and water – based ones.
Oil – based sealers penetrate the bamboo well and give it a nice, rich look. They also repel water pretty effectively. Water – based sealers, on the other hand, are more environmentally friendly and dry faster.
When applying a sealer, make sure the bamboo is clean and dry. Use a good quality brush or roller, and apply at least two coats for the best protection. Let each coat dry completely before applying the next one.
Installation Considerations
How you install your bamboo decking can also affect its susceptibility to mildew.
Proper Spacing
Make sure to leave the right amount of space between the bamboo boards. This allows air to circulate underneath the deck, which helps it dry out faster after rain or watering. If the boards are too close together, moisture can get trapped, creating a perfect environment for mildew to grow.
We typically recommend leaving about 1/8 to 1/4 inch gap between the boards. This might seem like a small thing, but it can make a big difference.
Elevation
Install your deck at a bit of an elevation. This helps to prevent water from pooling on the surface. You can use joists or blocks to raise the deck off the ground. If your deck is sitting directly on wet soil, it’s going to be a lot more prone to mildew.
Post – Installation Maintenance
Once your bamboo deck is installed, regular maintenance is key to keeping mildew at bay.
Cleaning
Clean your deck regularly. Use a mild soap and water solution and a stiff brush to scrub the surface. This helps to remove dirt, debris, and any potential mildew spores. You can also use a pressure washer, but be careful not to set it too high as it can damage the bamboo.
I usually recommend cleaning your deck at least once a month during the rainy season and every two months in the dry season.
Re – Sealing
Over time, the sealer on your deck will wear off. You should re – seal your bamboo deck every 1 – 2 years, depending on the amount of use and the weather conditions in your area. Re – sealing helps to restore the protective barrier and keep the moisture out.
Trim Vegetation
If you have trees or bushes near your deck, make sure to trim them regularly. Overhanging branches can block sunlight and prevent the deck from drying properly. Sunlight is a natural enemy of mildew, so letting more of it reach your deck can really help.
Dealing with Existing Mildew
If you already have mildew on your bamboo deck, don’t panic. There are ways to get rid of it.
Natural Remedies
You can use a mixture of vinegar and water. Mix equal parts of white vinegar and water in a spray bottle. Spray the solution on the mildew – affected areas and let it sit for about 15 – 20 minutes. Then, scrub the area with a brush and rinse it off with water.
Another natural option is to use a solution of baking soda and water. Make a paste by mixing baking soda with a little water. Apply the paste to the mildew and let it dry. Then, scrub it off and rinse.
Chemical Cleaners
There are also commercial mildew cleaners available. Make sure to choose one that’s safe for bamboo. Follow the instructions on the label carefully. Some cleaners might require you to wear protective gear like gloves and goggles.
After you’ve removed the mildew, make sure to treat the area with a sealer or preservative to prevent it from coming back.
Conclusion
Preventing mildew on your bamboo decking isn’t that hard if you take the right steps. By doing pre – installation treatments, considering the installation process carefully, and keeping up with regular maintenance, you can enjoy a beautiful, mildew – free deck for years to come.
