Re: Repair of Hollow Core Door
I agree with the previous posts, it's faster and easier to replace the whole door than to try and repair it, especially if this is being done for hire.
However, with some time, patience, and the proper tools, one could drill out the hole to a corresponding dowel size, cut and glue a piece of dowel in the hole, sand flush, fill, sand, and paint. Odds are, there'll still be a visible spot on the door in the area of the repair, and it may be prone to cracking around the repair over time.
I suffer from CDO ... Its like OCD, but in alphabetical order, LIKE IT SHOULD BE!!!
