Hey,

Laid a floating wooden floor on a concrete subfloor and now only have the baseboards left.
All the walls are lightweight concrete (Siporex), and the baseboards are lacquered oak.
Therefore, I'm very reluctant to plug and drill them (it would be too ugly with lots of screws in the baseboard because I can't fill and paint over).

I guess (but haven't tried) that it won't be possible to nail them with the nail gun. So I'm considering using something like PL400 and shooting a few nails just to hold them in place while it sets (if it's even possible to nail them temporarily).

The baseboards are slightly curved on the inside, so I'm a bit unsure how well the adhesive will grip.

This is what the shape of the baseboards looks like
Close-up of a curved wooden molding with a natural finish. The inner side is slightly arched, showing the detail and texture of the wood grain.

I thought about using quarter round afterward, a bit old-fashioned maybe, but I want to cover properly so the floor doesn't shrink so much that the baseboard doesn't cover adequately.

Am I completely off track, or is this a good way to solve the installation?

PS The entire baseboard is a bit bowed (now I'm not referring to the backside; they're not perfectly straight from the lumberyard). So there will be some tension in them that needs to be overcome before the adhesive sets.

I feel PL400 is a bit "too permanent," but I'm not sure how else I would solve it.
 
if you need to follow up with quarter moulding, you simply haven't done it right. Adding quarter moulding is honestly the ugliest thing you can do if you've laid a new floor. Horrible thought. The floor shrinks a maximum of 2-3mm so it is well covered with a regular baseboard if you have been somewhat meticulous.

If the wall is straight and nice, it's perfectly fine to use adhesive or PL400 that you apply (generous blob) on the strip at cc 600. Then you shoot with the brad nailer through these. This way, they stay in place while it cures.

Well, have figured out how it stands. I traced the last row off the wall wrong (which is not "straight and nice), I took 7mm too much.

So I'm weighing between quarter round to cover and ordering one more pack (2 weeks delivery time :confused:).

But clicking on pl400 and using the gun with cc600 still sounds smooth for the actual strip.

Will test laying out some strip with kvarits, still have some kvarits trim lying around in the same wood and finish that's to be set by some threshold.

Thanks!
 
yes, you can always check. But I think you can wait 2 weeks and then lay a new last row. You're going to live there for life anyway =)
A kvartsstav will trouble you to death for life =(

You're absolutely right. It's mostly me who got so tired of myself and was looking for "simple solutions" to an already quite simple problem. 2 hours of extra work is a small effort for a properly done room until we replace the floor in a long time.

So I know what I'm going to do tonight at least ;)
 
crack open a bira and think a little? =)

Perhaps a somewhat belated comment, but why use the depicted trim at the floor? It's a door/window casing …
A regular baseboard doesn't need a quarter round to connect to the floor.
