With having such a limited amount of characters that Google will show in your title, I don't think it makes sense to have the brand name in each one of the page titles (unless the brand name is a large factor in searches, and you are trying to ensure your site gets credit for being the official representation of that brand). Instead, utilize that space for adding additional or secondary keywords phrases that can help bring in additional traffic.
"A specific article would be "How to paint using oil painting | Maleribasen.dk"
This type of format can work well if you are trying to optimize for one major keyword phrase, and your whole focus (on-page and off) is around that phrase.
