Scribing skirting boards for 135 degree internal corners

I need to fit HDF skirting boards in my bay shaped conservatory.

There are 3 internal angles which I have measured at 135.3 degrees. My initial thought was that the angles are pretty spot on that I should just mitre them. I'm assuming that there will be no shrinkage of the HDF.

I did read somewhere that all internal corners and not just right angles should be scribed. It seems a significant amount of effort to do the scribes and get a good finish. As there are several internal angles, there won't be much room for error getting everything to fit accurately.

Appreciate any thoughts on whether scribing or using in mitres in this situation would be best.

Many thanks,

mitre the internals at that angle you wont get no shrinkage just use pva or mitre bond
Scribing is best but it isn't worth trying it yourself unless you are good at scribing, which even some chippies are not.

Get it all cut exactly, use mitre mate to stick it together first and then position it and fix it to the wall.

I wouldn't scribe HDF at that angle, and I can scribe. you will have to cut the scribe on an angle if you don't want a great gap to fil. As said HDF won't shrink
