Acid Washing...


I'm laying up about 900 sq ft of thin cut natural luck and stick, both inside and out. How long would you guys recommend waiting to give it a nice acid scrub? It's really not too bad at all, and I normally wouldn't, but it's a showcase home and want it sparkly.

Re: Acid Washing...


I usually think the earlier the better just so that mortar doesnt get too caked on there. Maybe a few days.

Re: Acid Washing...


Do you guys usually wait?

I always get anal about veneers and end up washing them all with a sponge at the end of the day.

Had a lot of bad days with a pressure washer as a laborer back in the day.

Re: Acid Washing...


A couple days , I usually mix 2 ice coffee cups of acid with 4 or 4.5 gallons of water. Scrub with a yellow bristle brush and hose off.

Re: Acid Washing...


Thanks guys. This job has been a bit different. I've laid some sections up, large gable ends, then had to wait and do inside work a couple of days, then hop to a different job for the GC, then back to finish the stone up. So some sections have sat for a week, and we had to buff up the concentration a bit, but I was mainly asking because of interior work were doing. They want to get in and trim and carpet right away, but I asked if they could wait a couple days so I can let the joints dry and acid wash it. Its down in a basement, and they dont lighten up too fast with the humidity we have.

Re: Acid Washing...


I usually dont use a pressure washer just an acid brush and a hose usually does the job. 9water- 1 acid is typical.

Depending on the mortar and temps, I'd wait a couple of days.
