How to waterproof shed walls
Prevent dangerous leaks from the very beginning by taking the following steps.
Step 1: Clean the walls
The first step in waterproofing your shed walls is to clean them thoroughly. This involves removing any dirt, debris or other substances that may be stuck to the surface of the walls. Use a stiff-bristled brush or pressure washer to clean the walls, making sure to remove any loose or peeling paint or varnish. Allow the walls to dry completely before proceeding to the next step.
Step 2: Check for gaps and cracks
Once the walls are clean and dry, inspect them for any gaps or cracks. These can allow water to seep into the shed and cause damage. Use a putty knife or scraper to remove any loose or peeling paint or caulk from the walls. Then, use a caulk gun to fill in any gaps or cracks with a waterproof caulk. Smooth the caulk with a putty knife and allow it to dry completely.
Step 3: Apply a waterproofing product
There are several different types of waterproofing products that you can use to protect your shed walls from water damage, including sealers, paints, and stains. Choose a product that is specifically designed for outdoor use and is suitable for the type of material your shed is made from.
Now:
Before applying the waterproofing product, don’t forget to read the manufacturer’s instructions carefully. Some products may require you to apply a primer first, while others can be applied directly to the surface of the walls.
Use a paintbrush or roller to apply the waterproofing product evenly to the walls, making sure to cover all surfaces.
Step 4: Apply a second coat
Once the first coat of waterproofing product has dried, apply a second coat to ensure complete coverage. This will help to ensure that the walls are fully protected against water damage. Allow the second coat to dry completely before moving.
Step 5: Install a vapour barrier
This step is optional, but it’s guaranteed to take your shed waterproofing to the next level.
The thing is:
If your shed is made from wood or another porous material, you may want to consider installing a vapour barrier to provide an additional layer of protection against water ingress. In case you’re not familiar, a vapour barrier is a plastic sheeting that is placed over the surface of the walls to prevent moisture from seeping through.
To install a vapour barrier, first, measure the length and width of each wall of your shed. Cut the vapour barrier to the appropriate size, leaving a few extra inches on each side to allow for overlap.
Use a staple gun to attach the vapour barrier to the walls, making sure to overlap the edges by several inches. Once the vapour barrier is in place, you can cover it with insulation or another layer of material to improve your shed’s energy efficiency.
Maintaining your shed
Even after you’ve waterproofed your shed walls, it’s essential to maintain your shed properly to ensure its durability and longevity. This involves regularly checking for any signs of damage or wear and tear, such as peeling paint, cracked caulk, or warped wood. If you notice any issues, address them promptly to prevent further damage.
But wait! There’s more:
It’s also important to keep your shed clean and dry. Avoid storing wet or damp items inside the shed, and make sure to ventilate the space regularly to prevent moisture build-up. If you live in an area with heavy rainfall or snowfall, consider installing gutters.
Bottom line:
Look after your shed, it will continue to have pride of place in your garden for a long time.
