How do you handle the 90 degree (or smaller) corners of your fascia where two sections meet? I know you can buy those plastic pieces that have two slots to slide down into the corner but I’ve been told they don’t hold very well. Any good ideas out there? I’ve even thought of using duct tape and paint over it with the fascia color but not sure how that would look. Probably not very good.
Are you talking about inside or outside corners? On inside corners, I push the masonite (1/8") into the corner, creating as tight of a radius as desired. I have been able to bend it as tight as about a 8-10" radius when needed. I then fill in the void with foam or plywood and use the added area for scenery.
On outside corners, I mitre the fascia to form a nice tight, clean joint. If the benchwork isn’t as deep as the fascia, the corners can be reinforced with a glue block on the backside of the fascia to help hold the joint tight. A small bead of woodglue will help hold the corner closed.
Jarrel, The plastic edging with two slots would be OK except that they are primarily used for 1/16" stock. If you can find some for the thickness of your fascia, you can spot glue it in place. I am assuming a vertical joint on an outside corner.
In my case, steel stud material. If the corner is at some angle other than that of the unmodified stud, I bend one flange to suit. Several of my fascia angles are 45 degrees, and I want to keep the fascia panels flat. With steel studs, that’s no problem.
Since there is no stress on flat Masonite (r) panels, simply screwing them to the flat surfaces of the corner studs is sufficient. I don’t plan any special external treatment.
If you go to the wood finish/trim section at your local home centre, you’ll find “L”-shaped trim pieces (usually around 8ft long) of various sizes and profiles. Just cut to length, glue and nail (use small finishing nails and pre-drill holes to prevent splitting) into place, and you’ll have a well-finished exterior corner that is paintable.
These trim pieces come in solid wood, finger-jointed wood, MDF, and even plastic (PVC?).
