Holes in the front door sill
My front door has a wooden sill which is rotting. I will eventually replace the door,which includes two side windows, but that is not financially feasible at this time. The holes in the sill are about an inch and a half deep, and the same wide. I fixed them last year with a wood filler. (Funny story on how I found that stuff) I filled the holes, sanded, primed and painted the sill. (I was quite proud of my efforts!) Unfortunately, that only lasted until spring when the paint peeled off, the fill cracked and came out, and the holes now appear to be deeper and wider. I was told that I need to prepare the holes first with primer. I could sure use some step by step instructions.
