Cabinets, Furniture, Woodworks - Exterior use of plywood


Expert: Greg Scholl - 11/13/2009

Question
QUESTION: I am repairing a garage door and plan of facing some old and weakened joints of the wood door with plywood sheathing. What is the best type of plywood to use on an exterior application that will then be painted?

ANSWER: What type of repairs will you be making? Marine plywood is really the best choice, but you'll need to go to a specialty wood supplier to find it...standard exterior plywood is not rated for constant exposure to the elements, and even painted won't weather well...can you use solid wood? Or make the repairs on the inside of the door?

---------- FOLLOW-UP ----------

QUESTION: The repair will be to the inside and outside at the bottom of the door. I was planning on sandwiching the bottom section and running a strip of pressure treated along the bottom edge to receive a new sweep.

Answer
Hi Len, I thought I sent out an answer yesterday, but I don't see it posted.....trying to do a sandwich type repair like you're describing will probably add quite a bit of strength, but it will be prone to weathering fairly quickly because of exposure, and it won't look pretty...it'll also add some weight to the bottom of the door.If this is a standard type garage door, you'd be much further ahead to remove the lower panel by raising the door, removing the hinge bolts and spring cables, slide the lower section down to the floor and then remove the roller guide bolts and remove the section. Then, it will likely disassemble further without a lot of effort,with a block of wood and a mallet, and you can remove the bottom rail from the door panel completely to do the repairs.Reglue any finger joints or other bad areas, and then using a table saw with a Dado stack or possibly a router,(tablesaw's a better choice) I would spline in a piece of 5/4 pressure treated or Mahogany decking (or even a spline of exterior 3/4 plywood) about 2-3/4" deep and glue that in place with some waterproof glue.This would make an invisible repair, not subject to the elements, or the need to be painted, give you solid wood in the center of the door for mounting the new sweep,strengthen the whole bottom piece...and it sure will look better. It also really isn't alot more work when it comes right down to it. Then reassemble the door section with a good waterproof glue and/or an adhesive caulk (paintable), and reinstall the section. I have successfully done this repair before myself...and it's undetectable except from underneath...and it has lasted several years so far....the bulk of the work is uninstalling and reinstalling the door section....but this is easy, just a bit time consuming, and worth the effort for the ability to do such a quality repair....in my humble opinion, of course.....post back- regards- Greg
