Forum Title: skimcoat and paper tape problems
I am not a contractor--just a diy homeowner looking for a couple of solutions. I've done a lot of taping with self-adhesive mesh tape. Seams around doors and windows eventually pop out so I thought I'd try paper tape. I think I've figured out why I get some larger bubbles and later peeling with paper tape--not enough JC underneath, right? One problem I haven't solved is why I get a fine, hairline crack around the edges of the tape and along that center fold line when I come back to sand and add another coat. Why is this? Sometimes it comes through additional layers of JC. Also, I've been skim coating to fill in dings from scraping wallpaper. I lightly sand then vacuum dust and wipe down before priming. Everything goes great during the prime and 1st coat of paint. At the 2nd coat of paint, I get tiny bubbles pushing the paint out that go back to the skim coat layer. I've had to go around with a pin and pop the bubbles and smooth them down with the edge the roller. Lots of them=big pain. Any idea what's going on here? Thanks in advance!
