I was wondering if there was any way beside scraping and sanding, to get a smooth enough surface to apply new ss tile back splash. After removing a painted brick facade the grout or mortar,glue are lseft which is a bumpy uneven surface. Was just wondering if ther are any suggestions before I make a huge dusty mess trying to scrape or sand it. It was applied directly to the original plaster and a few spots are nicked. would greatly appreciate any help. Thanks!
Use a pull scraper and get the high spots off. This causes little dust.
How smooth do you need it?
How are the SS tiles installed? Are they put on with a mastic?
If you need in very smooth, skim coat some compound on the wall.
