What happens here

Begin by applying a layer of drywall compound (mud) to all seams between drywall sheets. Embed paper or mesh tape into the wet mud, then apply another thin coat over the tape, feathering the edges. Allow to dry completely. Apply additional coats of mud, feathering wider with each coat, to hide seams and screw depressions. Once dry, lightly sand all areas with 80-120 grit sandpaper, being careful not to sand through the tape. For corners, use 3M adhesive corner spray or mud to attach corner bead, then mud over it. Finish with a skim coat, a very thin layer of mud over the entire surface, to ensure a uniform, smooth finish. Sand lightly after the skim coat dries.

Goal: Apply drywall tape and mud to all seams and screw holes, followed by sanding and a skim coat to create a smooth, paint-ready surface.

promise you when taping the joints essentially you're bringing two pieces of drywall together into one solid form and to do so you're gonna take your six inch drywall taping knife and spread the drywall compound along the joints then tear off the exact length of the tape that you'll need lay it over the compound and then use that drywall knife the same one and then run it squeezing all the compound out of that tape basically you're pushing it flush onto the drywall four corners I'm using this 3m adhesive corner spray you can always use the drywall compound itself and I've done it for years but this is the first time I'm sad to give it a try and it worked exceptionally well and the way you do it is you just shoot a light coat on the drywall corners themselves and on the inside of the corners you'll be putting on and firmly press it in together it dries very quickly and gets tacky super quick so be sure to use a respirator when using the stuff because this stuff gets real smelly after the first step drywall compound dry is using 80 to 120 grit sandpaper lightly sand all the harsh edges of the joint compound without exposing or sanding the joint tape that we lay down in our first previous step now that we got our first two coats of taping done what we're going to now is the skim coat basically you're blending everything together putting a really fine layer of the mud on and then after that we'll be ready for texturing [Music] so the particular style of texture we're gonna be doing is Santa Fe and Santa Fe is one of the easiest a lot of homes have that orange peel one which is kind of nice because you just spray but in the situation the best way I've learned to do this as you take your trowel or your knife whatever you want and you put a little bit on the edge and you do a few skips and then you kind of knock you down like that it's a little bit of finesse play around with it you pull Oh too much scrape it off try it again but play around with it see what you feel it feels good on the trout [Music] oh another little tip is when you do an area like this go a little bit further out to the good drywall that way it blends everything and I've learned that
