I have had plenty of experience over the years with spackling and taping....But even after all the research and practice I am still horrible and can't get it down right..... I figure I should have turned to the forums first! My latest project I cut a hole in the wall and a hole in the ceiling to fish wire through for hooking up a fan in the ceiling. I used the cutouts from the drywall for when I patched up the wall to spackle. I can't post pictures until I make 1 post, so pics coming whenever I'm allowed. But after placing the cutouts back in wall/ceiling, I spackled over it and let it dry..... The next day, being the spackle was a little rough from the first coat and the cut being a little jaggedy, I sanded slightly.....I then threw more mud over the cutout, put paper tape over the cutout, and layed more spackled over the tape and let it dry...... The next day, it needed a tad bit more sanding, but as I was sanding after the second coat of spackle, the tape started to show thru faintly....I had no choice but to lay more spackle down on the wall which will need more sanding..... WHAT AM I DOING WRONG, PLEASE HELP, SEND SOME GUIDANCE ADVICE, BECAUSE I have practiced and practiced for years with spackling holes, taping with paper tape and I am still beyond horrible, if its not flat spackle jobs, its the tape showing through after sanding.
