Scarf joints: Should be 15 degrees (22.5 will do) but not 45 degrees. 45 has too much overlap and a sharp, exposed edge: especially with vinyl coated MDF . Same angle with any running trim.

If you have a run longer than your material, make the splice with 90 deg matching cuts, glue and pin over a stud.

I prefer making a scarf joint when you have to splice a long run. It is simply an inside and an outside miter cut lapped together, over a stud. Also, nails that go in on a slight angle tend to stay better than nails that go straight in. Nail slightly upwards for the top nail, and slightly downwards for the bottom nail into the stud. A nail or brad gun makes this job a whole lot easier.

Always join two pieces in a less conspicuous area, not in the center of the room.

Small mistakes will stick out like a billboard to you, but others really won't notice them.

Use a power mitre saw.
