    I've been watching This old house since it was child, we didn't have cable and PBS was always the go to for my parents, I'm now 20 years old and living on my own. I want to buy a house soon and one of my biggest obstacles was my personal lack of knowledge about maintenance and repair of common household items. These guys give have always shown me how I can fix things on my own and they have given me hope for myself and I'll be sure to look to them whenever I need to fix or improve something. Its also good to see a familiar face from my past.

    As a painting contractor for 18 years, i don't agree that air drying joint compound with mesh tape is ideal. Mesh tape is designed to be used with quick setting joint compounds AKA hot mud. Also for an area that has cracked and been moving, paper tape is much better. In this situation Id recommend using standard air setting joint compound with a paper tape, your repair will last longer.

      @@stacyshaw1871 Those work really well for small jobs or touch up, however it's very difficult to get consistent results throughout a whole room. Also they aren't cheap, and some of them absolutely stink of solvents. It's a good idea to prime both before and after. Always do a test area on some cardboard to make sure the can is working as expected and the results can be excellent. As someone else said, on any large job or area, an air compressor powered sprayer is the only way to go. They run about a hundred bucks and getting the mix just the right consistency takes some trial and error, but if you're doing whole rooms it's a necessity.

    The link for the flexible patching compound is incorrect. It should be to a product like demonstrated, the DAP ElastoPatch (the container is turned away from camera likely due to licensing, advertising, etc). An elastomeric spackling compound is ideal for small, thin cracks and no sanding, with benefit of expansion and no further cracking. Latex paint works well.

      Same way. Just let the patch dry like he did and scrap all the boogers or sand. Then add a thicker coat of joint compound to match the existing texture and use what would match the patch. Usually a shoe brush, plaster trowel(for skip-trowel texture), sponge, or a crows-foot brush usually are the main texture. Pop-corn texture is sprayed on and usually sell a small repair kit for it that uses an air compressor

    Right side of the left crack wasn't sanded/blended enough. You shouldn't see a solid line between your compound and old paint.

    Also, I tried and prefer the randomly placed fiberglass tape over mesh or paper (unless it's a corner). Blends far better and I haven't had a single crack reappear (unlike some of my earlier repairs using mesh or paper)

      Christoper Meller: Some flex compounds are indeed sandable. The one I use isn't. Here are my tips.
      Strike off all of the compound when you apply it so that it's all in the crack and none (or just a haze) on the surrounding area. The compound shouldn't run the full width of your knife when you're applying it.
      What they didn't mention here is that the elastomeric (flex) shrinks, even though the package says it doesn't. At least that's been my experience. So I do a first pass with the flex, top-coat that with joint compound (after it dries), and then sand the joint compound. That gives me more control in feathering out the edges.
      I hope that helps.

  • @RixceU
    @RixceU 2 года назад +19

    This is not the best way. I suggest watching a drywaller channel, such as Vancouver Carpenter, for better methods to repair drywall.
    Mix your joint compound in a mud pan first, it will apply much smoother. Like others said, use fast setting type like Easy Sand 20 or 45 for the first coat with mesh tape, then all purpose for second coat.
    It doesn’t matter you you put on joint compound; it matters how you take it off. In other words don’t apply it little by little; apply a lot and then smooth it down in long, continuous motions. Feather the edges of the mud you apply by pressing harder on one dude of the knife as you smooth the mud.
    Use a wider knife (10, 12 inch) on the second coat. Because of the tape, the repaired area by nature has to be higher than the surrounding wall. You need to extend the mud by a wide margin and feather it so the change in height is not noticeable. If done properly, very little sanding is needed.

      Tried the damp sponge technique to smooth out seams and patches a couple of years ago. Haven't had to deal with dust from sanding ever since. Also since you use the sponge when the compound is still a bit damp to smooth the surface, once the surface is dry you can seal and paint. Cuts down on a lot of time.

      Anyone who works with drywall or plaster knows, you can't hide a taped joint with a 6" knife. It wasn't even a good demonstration.

    NOT a good video by any means. I quickly noticed two huge mistakes being performed that any painter or person with patching experience should have known immediately. Both repairs will fail within 1 year of completion.

      Paper sucks. It has no flexibility. Mesh only.

      So, you over charge people for half-assed work? That’s what “professional handyman” means in my experience. I’d rather learn something and have new tools at the end of my project than pay for someone else’s ego.
      The last “professional handyman” I encountered told me that it was impossible to replace my already grounded 2-prong outlets to 3-prong because there wasn’t a grounding wire and it would cost thousands to re-wire everything. Needless to say he left unpaid and 30 minutes, $14, and some RUclips videos later I replaced most of my 2-prongs to fully grounded 3-prongs myself.
      You remind me of that guy.

    Bad, tackle a real job. Thrown plaster, hundred year old cracks botched by previous caretakers. Cracks in plaster seldom run in straight vertical lines.
