When I was a student at Deer Creek Mackinaw (Dee-Mack) High School in Mackinaw, Illinois (1984 thru 1988) I was really into anything that was even remotely related to art. I loved drafting classes and all of the different art classes too. Our art teacher, Mrs. Schultz, organized some of the best art students there and had them paint a few organized and approved murals around the school. I was allowed to paint a Space Shuttle mural upstairs on the big 2-story wall just outside the library. I was also into space, and I had some NASA photos and mission patches and I basically just painted a collage of some of the items in that material. I dedicated the mural to the crew of the Challenger mission that was lost during their launch on January 28th, 1986. This large mural was a big project for a high school student … and I never actually technically finished the mural. I had intended to paint land masses on the earth, but never got around to it. I took these photos in the summer of 2002, so the mural was at least there for 14 years. I think they had to paint over it a few years ago, though.

A few years ago on my 15 year old concrete block house, one of my exterior window sills started cracking severely and eventually started falling off in large chunks. We had new windows installed, and that work basically did the old broken window sill in for good. I decided to try to form a new concrete window sill on my own. You can see in the photo below that the missing window sill and the broken pieces on the ground after I had ripped off all the loose pieces.

In the photo below, you can clearly see the rebar showing throughout the length of the fractured concrete surface. I guess that rebar didn’t help the sill stay in one piece. It actually helped break it apart once the crack had formed in the area of the rebar.

I got the surface really clean and free of dust and conrete pieces. Then I painted on concrete adhesive that I bought at my local home improvement store. I’ve never used this stuff before, so I don’t know how well it works. As you can see from the photo below, I then mounted some wood strips that were about a half an inch thick to the wall with tapcon screws. These wood strips would become the bottom and side surfaces for my concrete sill mold.

Then I screwed a 1×6 plank that I had laying around to the wood strips. I mounted the top of the plank at the same height that I wanted the top of the new window sill to end up being. I then mixed up some concrete and poured it into the mold. I made sure that the top surface of the new sill slanted down and away from the house. Otherwise, water would pool instead of running off. The photo below shows the mold filled with concrete and curing with plastic around it.

The new sill is perfect. Eventually I got the house painted and the photo below shows the final painted product.
