Skim coating textured drywall
Comments (11)SOS-feeling like this thread might have the answer I need! Skim coating over a really bad knockdown texture. I have done three coats with all purpose lightweight joint compound overall it’s looking pretty good! Only issue is there are still some high point from the knock down still showing through. I don’t think I can sand them at this stage without destroying all the work I have done. What should I do? Additionally, on the walls that look ready. I’ve gone over everything with a light and touched up the places I noticed. I’ve run my hand over the wall more times than I can count to make sure it’s smooth. However, I’m really worried that when I paint sections that aren’t level will be very apparent. Does anyone have any other tips to make sure everything is ready to prime and paint? Would priming the walls and then If anything comes through doing another coat be a terrible idea? It’s been a messy and time consuming process and really can’t wait for it to be over hahah Thankful for any advice!...See MoreHow to Skim Coat Drywall?
Comments (14)"Skim coating with drywall knives is a nighmare." Yes, we learned this the hard way. A trowel would be easier, although it takes some time to get used to using it. "3. has anyone tried this "Dustless Drywall Hand Sanding System" (see link below) from Home Depot? It attaches to a shop vac and uses a 5 gal tank of water to trap the plastet dust." We rented this machine from HD. We were pleased with the results. It sanded large surfaces smooth with very little effort and kept dust to a minimum as long as the bag is not full and the hose attachments are properly connected. If we should tackle this project again in another room we will use the trowel method or perhaps slightly thinning the compound and rolling it on with a paint roller....See MoreXpost in Baths, Can I Skim Coat New Bathroom Drywall and Plaster?
Comments (2)Thanks Casey, What is a good oil based primer. I will be using BM paints for the room. I could get their primer. I have only used Zinzer primers up to this point, in my kitchen, and now bathroom. My progress: Last night I went ahead and thinned down some green topped joint compound (drying type, I believe it is called, as opposed to setting type) and rolled it over the Gardz primed walls. After I knifed it off you could barely see the application, just a soft haze. My thought is that I will now apply another thin skim, then when dried, prime for painting. I just don't want these layers to delaminate in the bathroom. This isn't a steamy room because there is no shower and the tub is rarely used. But it is a bathroom none the less....See MoreAmateur needs some tips on skim coat plastering
Comments (7)Shimming is very slow and a real PITA. You can get a faster result by using 2x2s (I use ripped down 2x4s) and attaching them to the edge of the present studs protruding far enough to create a new flat plane for the drywall. Find the highest spot on the existing studs and make the entire wall match that. Either screws or a nail gun make quick work of attaching the new strips to the sides. Hammering nails allows the new studs to move around too much (and old wood can be very hard). If the area is large enough a laser level projecting a plumb line and a wooden gauge can be used to quickly align the front edge of the new sisters as you move across the wall. Attach new wood to every stud so the screw spacing will be uniform. Some painters tape and a marker allow for transferring the stud locations to the floor for weasier wall fastening if there is any irregularity in the studs. Skim cioating for smaller areas isfaster with a plasterer's trowel (instead of a srywall knife) and use Easysand or Durabond. 120 minute if you are a little slow, 90 if you are faster. If you mix these compounds about as thick as peanut butter (smooth with no lumps please) there wil be very little shrinkage as they harden. Unlike pre-mix that hardens by evaporation, Easysand and Durabind harden by chemical reaction....See MoreGreenDesigns
