High miter box and how to attach baseboards to concrete

[prunila]

Hello!

Question number 1:
Wondering if anyone has seen a miter box for tall baseboards? My baseboards are 13 cm high and I have been looking for a box that can accommodate that size but can't find one that is that tall.

Question number 2:
The old baseboards were attached to the concrete/brick wall with very large and strong nails, and it's not something I can do myself. Now I'm wondering if anyone has tips on how I should best attach the new baseboards? Should I buy a strong adhesive? Or do you think nails could work?

Thanks!

Cut with miter and bevel? You can saw the moldings while lying down?
The inner corners can be scribed to avoid gaps.
For fastening, I used dowel screws which I countersunk and filled over.

Edit;
There are trim screws for concrete that don't need plugs, just a pre-drilled hole.
There's a special type of nail gun that handles steel brads for concrete.

Answer to question 2. It is possible to glue baseboards to a concrete wall (I have done it myself with good results). We used the adhesive No more nails. The heavy nails currently in place are likely set with a so-called dyckertpistol. They leave some marks in the baseboards.

Answer to question 2. It is possible to glue skirting boards to a concrete wall (I've done it myself with good results). We used the adhesive No more nails. The strong nails currently in place are likely set with a so-called nail gun. Leaves some marks on the skirting boards.

Thank you so much! I think I'll go with glue. Feels much simpler.

Thanks for the tips!
Regarding a miter saw, unfortunately, I don't own one and only have a few moldings to put up, so it seemed like an unnecessary investment right now. Do you have any other tips for cutting at 45 degrees? I own a jigsaw and a handsaw.

If you have a steady hand, you can solve it with the jigsaw. The alternative is to rent a miter saw from a rental company; it usually doesn't cost much (not where I live anyway).

Regarding gluing the baseboards, you have to consider whether the walls are straight; it can be difficult to get the molding to adhere to the glue if the wall is crooked and the molding needs to be forced against the wall.

Hmm yeah, renting is an idea. Not quite steady with it yet unfortunately.

Yes, that was something I thought about. Wouldn't say that any of the concrete walls are completely straight. Can you try and then remove with something like a chisel and hammer if it doesn't work out with the glue - or is it a lost cause once it's glued on?

Once you've glued the baseboards, you don't want to try to take them off again. I would have rented a hammer drill and fastened the baseboard with screws if there's a place it needs to be forced against the wall.

An alternative to screws and plugs is to drill and glue an 8mm dowel or träplugg into the wall, which can then be nailed into. Holds really well.

Ok great! I have a hammer drill, so I'll go with that. Thanks for the help!

To miter without help I think is a little tricky. Especially if you are not used to it. This might be an alternative: https://www.hornbach.se/shop/Geringslada-for-dekorlister-MB2-liten/6250055/artikel-detaljer.html
