Acid Etching Walls

[SH_82]

Have a home built in 1960 and I'm renovating the garage. I have bare concrete on the walls that I plan to use Loxon Primer/Sealer prior to painting with an exterior latex paint.

Would it be overkill to acid etch these walls or will the Loxon probably adhere well enough with 2 coats?

That does not look like 1960 concrete.

Either way I'd paint directly on it.

Are the concrete walls retaining walls?

What about acid staining. I've done a bunch of floors using a waterborne acid stain ( Kemico) that turn out really well. Recently stained the slabs I poured for a 500gal propane tank and a stand-by generator with stain I had left from a job a few years ago. Other pic was the part of my old garage I turned into an exercise room.

Not sure what you'd classify them as but basically on 2 of the 3 non-garage door walls there is this concrete about 3 feet high and then sheet rock the rest of the way up. The odd man out wall just has plywood

Following as I have considered the same project myself.

I think what he's asking is if there's earth against the outside of the concrete or if they are above grade. If there is dirt on the other side you should probably make sure the walls stay bone dry, or paint will have a hard time sticking.

Personally, I'd be reluctant to paint concrete...once it's painted, you're doomed to having to repaint it every so often for the rest of time.

Ahh thanks for clarifying. That does make sense. Yep, one wall is above grade and the other has dirt up against it with a raised flower bed.

Will Loxon XP primer help block out that moisture? Are there any other sealants that may help in this situation?
