Topic tags/keywords: mastic removal

I’m on a crusade, which involved removing all the godawful old paneling from my home. This month, I’m working on our former guest room to re-task it as a nursery. The first job was easy enough…pulling all the old paneling off the wall. Now I’m left with plaster walls which need some patching for nail holes, etc., but there are tons of gobs and lines of mastic everywhere!

I have an old hand-scraper which I used to smooth one wall. This was some exhausting work, and since I’m pretty lazy, I’m looking for a quicker solution. I’ve already tried an RO sander with an aggressive grit, but the mastic thrashed the sandpaper in no time.

Chemicals?

Other clever tools?

Anyone with ideas?

I have not had to deal with removing mastic. So take this suggestion with a big lump of salt – how about using a flat blade shovel? But it is good only if it doesn’t damage the wall. I suppose a belt sander used very carefully to knock the high spots may work also.

Use a wall paper scraper. It’s actually a peeler. About a 3” straight razor blade set slightly at an angle on about a 10” handle. Peel the stuff off, don’t scrape.

Thanks, Catspaw, I was just looking at one of these on a big-box website. It looks like they’re pretty cheap! About $8, and replacement blades are available. I’ll give it a shot!

After reading Catspaw’s suggestion, it sound a whole lot better than mine of scrapping the mastic off.

Believe me, Dalec, I was thinking along similar lines. The belt sander was something I was considering.

I got the wallpaper scraper, some extra blades, and some adhesive stripper/softener. I’m going for a combined approach.

Is it maybe a lot faster to just drywall right over the top of it. You might weigh cost and time. Also look at how the door trims and base moulding will be or need to be replaced.

I considered that, PaBull, but the the globs would have made an uneven surface over which to lay the drywall. Besides, I’m on a big time and budget constraint, so I tried the wallpaper scraper.

Man, did that ever work great! I invested about $15 in the scraper and a couple of packs of razor blades, and made very short work of the mastic. That stuff practically jumped off the walls. Now I’m mudding over the nail holes and little spots where the mastic pulled off old paint and loose plaster. Maybe I’ll post some pics in a project.
