I have this small wall that has surface imperfections (not holes). Heard about something called "skim coating" where you mix water with drywall compound and apply it to the wall.
1) How thin should I make the compound before applying it ? Is it just water + compound? 2) Can I use a heavy-duty textured roller brush (loops) to apply this compound ? I have this one from Lowe's already:I've also seen something called "texture paint" which you apply over the drywall to also mask surface imperfections - is this a better or worse alternative to skim coating with joint compound?
Thanks.
