This step is crucial before weatherproofing as it allows you to identify any issues or wear and tear. Failure to do so may affect the effectiveness of the process. It may also lead to suboptimal results, causing further damage to your plastic shed.

To inspect:

  • Check for cracks or holes. Such damages may seem small at first, but they can allow water and other elements to penetrate the shed. Also, keep in mind that they can become larger over time and cause more significant damage.
  • Look for fading or discolouration. Overexposure to sunlight can cause plastic sheds to fade or discolour. This can be a sign of weakness and make the shed more susceptible to other types of impairments.
  • Inspect the roof. The shed’s roof is particularly vulnerable to weather damage. Check for any holes, cracks, or missing tiles that can cause water damage to the interior.
  • Examine the foundation. Ensure it’s levelled and secure. If the shed base kit is not, the garden building can shift or move, causing structural damage.
  • Watch for mould and mildew. Mould or mildew growth is fond in areas with poor ventilation or high moisture levels. Not only can overlooking them cause severe damage to the shed, but they also pose a health risk.

Identify any issues that need to be addressed before applying waterproofing materials. This ensures your shed is well protected from the elements, and you can extend its lifespan.

Some weatherproofing materials are not suitable for garden sheds plastic. But the following options are appropriate:

Sealant

A sealant is applied to the surface of the shed to create a protective barrier against moisture. It’s easy to apply and affordable, making it a popular choice for DIYers.

Paint

Yes, you can paint plastic storage sheds! In fact, doing so can provide an extra layer of protection, as well as enhance its appearance. But it’s important to use the right type of paint and techniques to ensure the paint adheres properly.

Use a paint that is designed for plastic surfaces, such as acrylic or latex-based paint. These paints adhere well to plastic and provide excellent protection against the elements. Before painting, ensure that the garden building is clean and dry.

Spray-on coatings

Sure, painting your heavy duty plastic shed is possible. However, it may not be necessary if your primary goal is weatherproofing. This is where spray-on coatings come into play.

Spray-on coatings provide a long-lasting protective layer against water and UV rays. Although more costly than other materials, they offer excellent protection and durability.

Tarpaulin

Tarpaulins are heavy-duty sheets that can be used to cover sheds. They are a cost-effective way of providing temporary protection, particularly during winter.

To use, measure the dimensions of your shed and get one that’s slightly larger than the unit itself. This will allow you to cover the entire structure and ensure it’s protected from the elements. Drape it over the roof and sides, making sure it’s taut and secure.

  1. Clean the surface. Make sure the surface of your plastic potting shed is clean and dry. Remove any dirt, debris, or grime with soap and water, and let it dry completely.

  5. Allow the material to dry. Let it dry completely according to the manufacturer’s instructions. This may take several hours or even days, depending on the product and weather conditions.
