I have a one car garage that was a add on to my house long before I

bought it. The wall consist of concrete blocks about three high and a

2x4 wall the rest of the way up. Where the wood meets the block is

beginning to bow in the center and there is a 1/16" x 4' gap between

the two. I tried to fill one of the areas with great stuff and

realized I was just filling the block and it could take dozens of cans

to fill it. Does anyone have any solution on how I can seal up the

area or maybe secure the wood to the blocks better????
