The Importance of Sealing Your Shed
Rotting wooden sheds can be a significant issue with wet weather conditions. Sealing your shed creates a barrier that prevents water from seeping into the structure, weakening it over time. If there's too much moisture, mold and mildew can develop, posing health risks and damaging stored items.
Beyond weather concerns, pests can become a nuisance by eating away at the structure or chewing on wires and furniture. Sealing any gaps minimizes the risk of pests getting in.
If you plan to use your shed frequently during the winter, sealing it can improve insulation, making it warm and cozy. Additionally, sealing your shed helps keep it cool in the summer, making it an ideal space for a children's playhouse or workshop.
Proper sealing extends the lifespan of your shed and enhances its usability throughout the year.
6 Ways to Seal the Bottom of Your Shed
1. Install a Damp Proof Membrane (DPM)
A damp-proof membrane (DPM) is a thick plastic sheet that prevents moisture from building up underneath your shed.
Secure the DPM beneath the shed's frame with adhesive tape. For protection, add a soil layer before setting the shed foundation on top.
Benefits of using a DPM include:
Moisture Protection: The DPM prevents moisture from seeping into the shed's wood, guarding it against rot, mold, and fungal growth.
Structural Integrity: It helps maintain the shed's structure by preventing warping and decay.
Pest Deterrence: A dry environment is less appealing to pests, reducing the chance of infestations.
2. Use Pressure-Treated Timber
Pressure-treated timber is popular because it’s durable and requires low maintenance. The wood is treated with chemicals to make it more resistant to moisture, fungi, and wood-boring insects.
Using pressure-treated timber in your shed’s construction, such as for the floors or roof, can enhance its longevity. Be sure to use nails, bolts, and screws to secure it, as the chemicals in the wood can erode other metal fasteners. Benefits of pressure-treated timber include:
Rot and Pest Resistance: It’s highly resistant to rot and decay from moisture and can prevent termites and wood-boring beetles from damaging your shed.
Cost-Effectiveness: Although the initial cost is higher, it reduces the need for repairs, saving
you money over time.
Versatility: It can be used in various shed parts, including the base, framing, and exterior cladding.
3. Apply Silicone-Based Sealant
Applying silicone sealant to your shed can enhance its durability by protecting against pests, rot, and structural damage.
Put the sealant on with a caulking gun along the seams of your shed, focusing on gaps around doors, windows, and walls. For a thorough seal, smooth the sealant into the gaps with a dampened finger or a caulking tool. Benefits of using silicone sealant include:
Moisture Resistance: It prevents water from seeping into the shed through gaps and joints, reducing the risk of rot and mold.
Flexibility: Once cured, silicone remains flexible, allowing it to move with the shed’s natural expansion and contraction due to temperature changes.
Durability: Silicone sealants can endure direct sunlight, extreme temperatures, and heavy rain.
4. Fit a Metal or Plastic Base
Metal and plastic bases are excellent outdoor structures because they resist moisture and help prevent rot and fungal growth.
Metal bases are usually made from galvanized or powder-coated steel, while plastic bases are commonly made from high-density polyethylene (HDPE). These bases are placed on the ground before the shed is built on top, creating a protective barrier. Benefits of using a metal or plastic base include:
Ease of Installation: Metal and plastic bases are generally easier to install than concrete or wooden foundations.
Moisture Resistance: They don’t absorb moisture, which helps prevent rot, mold, and fungal growth. This makes them ideal for wet climates or flood-prone areas.
Durability: Metal bases can handle heavy loads and harsh weather conditions, while plastic bases resist cracking and UV damage.
5. Use Gravel Borders
Installing gravel borders around your shed helps with drainage and can extend its life. Gravel prevents water from pooling around the base, making it harder for pests to dig through.
To create a gravel border, remove any weeds and lay down the weed barrier fabric before adding the gravel. A 5—to 8-cm depth is usually sufficient to protect your shed. Other benefits of gravel borders include:
Weed Control: Gravel prevents weeds from growing, keeping the area around your shed tidy and reducing the risk of weed damage.
Looks Better: Gravel borders come in different colors and textures, which can improve the appearance of your shed and make it look nicer.
Stability and Support: Gravel helps distribute weight evenly around the shed, preventing it from shifting or sinking.
6. Add Skirting Boards
Skirting boards are not just for indoor use but also for sealing the gap between your shed and the ground. They help keep pests out and give your shed a cleaner, more finished look.
To install skirting boards, attach them around the edge of the shed floor, fitting them tightly against the wall. For wooden sheds, use screws or nails. Metal or vinyl skirting may need special brackets or clips. Other benefits include:
Weather Protection: Skirting boards help protect your shed from water splashback and debris buildup.
Improved Insulation: They can reduce drafts and heat loss, making your shed more energy-efficient.
Added Stability: Skirting provides extra stability, helping to keep the shed secure and preventing it from shifting or settling over time.
