Whether you use it for storage, garage, barn, or stable, any outdoor shed is susceptible to the elements. For instance, moisture can typically invade and collect in the shed’s interior. So even if the climate is hot and dry, moisture can still be a problem.
How moisture gets in the shed
Outdoor sheds may not be as moisture-tight as your home. Most of them have several hidden entry points for moisture to enter. If not finished correctly, the walls can be vulnerable to it. If you construct it directly on the ground, water can penetrate the walls and the frame in contact with the soil.
So, how can moisture-proof your shed? Here are some tips.
- Build a stone foundation
The cheapest and fastest way to protect your garden shed from moisture is to build a stone foundation. You can dig a foundation on your lawn about five centimetres deep and compress it with a compactor. Use patio stones cut to size and fit them together. Put the pieces together as tight as possible. Add filler materials between the stones to prevent the weeds from growing. Finally, construct your shed on top of the stone foundation.
- Construct a concrete foundation
If you have a larger shed, or you want a more solid foundation to fit the condition of the ground in your garden, construct a wood mould according to the thickness of the foundation you desire. Pour concrete into the mould, and let the concrete cure for seven days. Then, seal the concrete foundation to make it waterproof and start building your shed over it.
- Protect roofs and walls
You can also make your garden shed waterproof by coating the roof and walls with polyurethane. Polyurethane bonds to most surfaces, so you can use it to paint roofing materials, wood panels, and even concrete floors. It can seal cracks and tiny holes, prevent rust, repel moisture, and make surfaces non-slip. You can visit durabakcompany.com and see its polyurethane coatings and the colours available.
- Use plastic foundation
If you want something eco-friendly and easier to install, consider purchasing plastic shed base grids, which are made of recycled plastic. The material ensures that the shed footing will not rot. It can be an alternative to a concrete foundation. You can fill it with shingle aggregate or stone to have a full draining foundation raised above the ground.
- Install windows and vents
Promote good air circulation by installing vents and windows. Aside from providing proper ventilation, windows allow light to come in so that you can save on electricity. Use caulking or weatherstripping to seal the vents and window frames. Likewise, air circulating inside the shed will help dry moist areas.
You can also use other products, such as charcoal briquettes that absorb moisture naturally. They are cheap, and you can use them for one to two months. Finally, do not forget that having an electric fan inside your garden shed will not only keep you cool but can also keep your shed dry.
