Worked great. I’d recommend primer before painting

This is tricky stuff to work with. The material it's made from is flexible which makes it difficult to keep dead straight when fixing to the wall. Cutting mitres is a similar story, difficult to get these exactly right. I marked area with pencil lines and used a spirit level to try and keep it as straight as possible, the corners dont look 100% as the material moves slightly when cutting. Adhesive is strong, no issue with sticking to the wall and staying attached. Its the fine details that let this down in my opinion. Not sure if there was a corner mould available, would have meant no need for mitres and made the job tidier in my opinion.

Doesn’t stick that well
