Our 50 yo c/d grade ranch house is finished inside with rock lath and a verrry thin (1/16 to 1/8 thick) plaster skim coat. The skim coat is full of hairline cracks, in some paces every few inches. On some surfaces, the stuff is loose, and probably needs to be removed.
I believe the best way to fix this would just be to drywall over it, however we have little time to do the work, and having it done is prohibitive.
In researching plaster repairs I've seen that in some cases the setting type compound is recommended for a skim coat. As it stands now, this would be the preferred material, as it is sandable. However, I have not seen any articles specifically pertaining to repairing the cheapo skim that coat we have.
What I wish to accomplish is a quick repair to skim over the areas having hairline cracks, feather it out nicely, and fill in some of the areas where it had been repaired before that remain a little low, so that once it is painted, it looks smooth, and I don't feel nauseous when I look at the walls anymore. :eek: And I'd like it to last a few years.
So currently the questions are,
Anyone done this before?
Is the sack-o-stuff from HD any good (sheetrock brand setting type)?
What is a recommended thickness of application? Can we get away with 1/32 or less (to allow feathering out)?
Any thoughts on roughing up the cracked areas with a disk prior to application? (Yes I've done body work before):p
What about a bonding agent? (It's going over the paint)
Anything else to beware of?
Want to blast through this and get it done with minimal hassles.:D
Thanks for the advice
