Pre-Sand Existing Wall Texture

would take too much to skin coat to get rid of those so i'm just going to sand that down with a festool planet sander using an 80 grit so i'm going to sand it really quick knock that stuff down and then i'm going to skim coat it with a bow arrow product it's a water resistant gypsum powder i'm just going to mix that up skim coat this wall and you can sand it in about two hours it dries really quick so get that wall skim coated then we're gonna prime it and we'll get working on our venetian plasters so now i've got to everything off the wall here i'm going to run some tape down here on my baseboards so when i do the sanding process if i accidentally hit the baseboards i don't want to nick or dig them the tape will add kind of as a buffer and so i'm just going to take this off real quick here and i'm using right now this is uh blue tape from frog tape so this will also be my tape that when i begin um doing the process the venetian plaster nothing will bleed underneath the tape now if you haven't seen the phonics this is a festool clinic's right here wall standard ceiling sander i'm going to hook it up kind of vacuum to hook it up too so i don't make a big mess also you can see where it's starting to knock down some of these really uh large peaks right here and knock them down really fast so really simple just keeping the sander moving really quick if you don't keep it moving it's going to heat up really fast and it's going to gum up your sandpaper so we just want to move quickly
