Drywall Prep/Repair...Baseboard Questions

[galaxy]

So I’m getting ready to paint and I want to install the rubber baseboard trim, but I need to do some prep work to get the walls ready for paint and to adhere the baseboard to the wall. Attached a couple of photos so you guys can see what I need to work around. In the photos, you can see where the existing paint and whatever else is flaking off. Also, the concrete from the stepped sides of the foundation is really flaking away.

I want to go with like an 8” baseboard to cover most of this up, so mainly I want to learn how to prep this so that the baseboard stays in place.

I am also planning on taking the baseboard all the way to the floor, covering the exposed foundation sides on all of the walls except one. In the pics, you can see I have one wall where the wall is recessed, so I won’t be able to run it all the way down on that wall.

So...my questions are this...

- how to I prep this drywall along the bottom to get rid of those flaking areas in preparation for paint and baseboard attachment??

- what should I do to fill in that concrete and stop that from progressing or to just make it look descent?

- where’s the best place/brand of baseboard to get? I know if comes in big rolls, but hardwares stores only seem to have 4”, and I know it come soon in wider.

Thanks guys.

looks like your concrete stem wall is deteriorating, any fix is probably temporary as it will continue to shale off.
for the drywall, scrape loose & peeling off, and use cove base cement. prime first or not, cove base will stick to either bare or primed drywall. check for a commercial flooring store in your area for 8" rubber base.

Your flaking paint is due to moisture wicking up the drywall touching the concrete.
Cut the bottom 1 inch away from the concrete.

A floor tile store should have 6, 8 and 10 inch high base molding.

If you are covering it with wide base you might think about replacing the bottom few inches with pvc vinal. This would stop the wicking action, and you would not have to tape it.

What do you mean by tape it?

drywall tape/compound

I meant what do you mean by me needing to tape it? Because my plan was to take a stuff bristle brush and knock the flaking stuff off and attach the baseboard.

There needs to be no contact between concrete and drywall. If there is, fix that first.

1/2 gap is what i always go for

Is there nothing effective to fill the crumbling concrete? As you can see on the one wall, the baseboard will not cover it. On that one wall, the baseboard will be against the wall but the bottom will be up on that concrete ledge.
