Sealing the Deal: A Guide to Repairing T-111 Siding on Your Garden Shed (2023 Update)

My 10x14 garden shed needs some siding repair. The exterior is T-111 all in good shape except the right side (when facing door),

I put my canoe between the shed and the privacy fence (mine) when not in use for long periods of time. So, FF the rain that ran off shed roof hit canoe and back-splashed onto bottom 20-22 inches of siding. It curled up, split and is done for.

(the 14' length requires 3 sheets of T=111)

My plan is to cut the end sheet(s)off at 24" and the middle sheet at 20". That way no joints will line up together. Now all the above for this question.

After new sections of T=111 are cut and ready to nail in place how and what do I use to glue / seal the joints together to make them waterproof.

Somebody hep me !

Thanks

To repair the damaged T-111 siding on your garden shed, follow these steps:

Cut the damaged sections of siding to the appropriate length. In your case, you mentioned cutting the end sheets off at 24" and the middle sheet at 20".
Clean the edges of the siding and the areas where the joints will be made. This will ensure a proper bond between the siding and the sealant.
Apply a continuous bead of silicone caulk along the joint. Silicone caulk is flexible and durable, making it a good choice for sealing the joints in your T-111 siding.
Use a caulk smoothing tool to evenly distribute the caulk and smooth out any air pockets.
Repeat the process for all the joints in the siding.
Allow the caulk to dry completely before painting or staining the siding.

Here is a list of tools and materials you'll need to complete the job:

Silicone caulk

Caulk smoothing tool

Utility knife

Clean rags

It's important to remember that while fixing the siding yourself can save you money, proper sealing of the joints is crucial to ensure the longevity and durability of the repair.

Additionally, it's important to take the time to properly prepare the surface before applying the caulk. This means cleaning the edges of the siding and removing any dirt, debris, or old caulk that may be present. This will ensure a strong bond between the siding and the caulk, and will help prevent water from getting into the joints and causing further damage.

When selecting a silicone caulk, look for a product that is specifically designed for exterior use and is formulated to be weather-resistant. This will help ensure that the caulk can withstand the elements and keep your siding protected for years to come.

Finally, be patient and take your time when applying the caulk. A smooth and even application will help prevent the caulk from cracking or peeling over time, and will ensure that the repair is as effective as possible.

By following these steps, you can successfully repair the damaged T-111 siding on your garden shed and protect it from future water damage.
