Repaired potting shed window sill!
Here is a reminder of where I started.
A photo of the hole I found after I cleaned
all the rot away.
First I had to add a "floor" so I had something to support the new sill.
Before I put the "floor" in I treated the surrounding wood with
a fungicide and an insect treatment. The next day I added a
wood hardener to the old wood.
I used a scrap piece of wood I had in the basement for the floor.
I pounded it into place so I had a tight fit.
My local fence contractor puts out scraps of wood in a bin in front of their shop.
I cut the sill from a scrap of cedar I found in the bin.
Around the sill I added 2 part epoxy to fill in the smaller spaces.
Each of the steps takes a day because each product needs to dry.
The last step was to paint the sill with "Beyond Paint," which is a wonderful
indoor and outdoor paint that is both a primer and finish coat.
And it sticks to anything.
Done. Now onto the next late summer project.
