Defects may show as shadows that need further sanding to get a flatter ceiling or wall. While sanding you’ll want to run a work light casting across the ceiling or wall to pick up any defects. In the corners of the room you can use a sanding block or we sometimes use a Festool DTS 400 hooked up to our Festool Vacuum. Use a pole sander with extension or mechanical sander such as the Porter Cable 7800 or Festool Planex attached to the CT 36 AC vacuum.They’re really thick and if spraying you’ll need a pump like the Mark V or Graco 1595.

Using a Graco Mark V, spray your texture with a LTX 529 to 535 tip and smooth out with a sheet rock smoothing blade.If using hawk and trowel method you thin joint compound very little if at all. Lay your mud onto the surface and pull the mud tight so a light skim coat is applied. Using a 14 inch flat bladed trowel, load up your hawk with all purpose joint compound.Without getting too far ahead smooth out the rolled on texture with a 14 inch taping knife or a squeegee trowel. Using a 1 1/4 inch nap roller screwed into an extension pole, roll 1st coat of mud.If you plan on applying with a hawk and trowel you’ll want to thin very little if any. If spraying or rolling mud, thin mud to the consistency of pancake batter. Before skimming you’ll want to mop or vacuum off the ceilings so your skimming mud doesn’t get flecks of debris in it.If applicable to this situation, please see our post on how to remove popcorn texture.
