Skimming Over Spatter / Knockdown Texture Question


So I just put an offer on my first house today, and hopefully I'll be able to use some of my renovation skills to improve it from the "worn" state it is in right now. I'll be starting with plumbing and electrical upgrades, but before I paint, I'd like to skim over the cheap looking spatter texture and make it a smooth surface. The walls are already painted, and quite dirty.

Questions:

1. I'm a novice drywall finisher. I can patch very well, but I've always subbed out big jobs because I'm no professional, and I'm way too slow to keep from losing money. Is this way beyond the capabilities of a novice, or will it just take me more time and touch up?

2. Prep: Should I just TSP the walls, prime, both or neither? Should I use a power sander to flatten everything out first to make the skimming easier?

3. Filling: What compounds would you recommend? Would you recommend multiple layers, like a fill coat with plus 3, and then a skim with topping?

4. Is skimming the wrong way to go? What other methods are there?

Skimming is probably the right way to go on this but if your a bit on the novice side, I guarantee that you'll want to hire it out. I'm pretty decent with finishing a freshly boarded room but skim coating is a different world...
I lucked out and found a finisher that is the best quality work I've seen and charges a low price. I do a lot of bathrooms and hire him for all of it and he did some skim coats. He makes it look easy but he says it took him a year or so just to get it down pat(that's after 3 years of being a new construction finisher)
He slicks out with 2 thin coats of sheetrock 45 then hits the money coat and touch ups with LaFarge and wet sands... and to start he will do minimal scraping(just bad spots) he says if you scrape too much it lengthens the process

I'm ok with it taking a long time if I can get it to look good. I'd also like to improve my knifework. I'd appreciate some more tips on how to do it, and I'll start on a small hallway and call my drywall guy if I need him

Go thin and use hotmud(try the 90)
1st coat- vertical
2nd coat- horozontal
3rd coat- vertical // use LaFarge

Your own place is a good place to practice!

I would clean walls if they are really dirty first. Then roll thinned 90 with smooth roller, then wipe down. do this twice . Then skim with bucket mud thinned or plus three.

By wipe down, I'm assuming you mean smooth out with my knife?

Sorry, yes. Wipe smooth, don't take it all off , don''t worry about lines or trying to make it pretty on fisrt coat. Just try to keep depth consistant.

Wipe off,put mud in pan as your doing this,when pan gets full dump back into bucket with roller and repeat process.

Does he not run a chance of getting pieces of the texture he is trying to cover in his fresh mud which will cause problems? Or does it not matter at this stage?

Anything is possible. I would hope the old texture your skimming is not coming of too easy.

Always inspect,clean and scrape/sand/prep walls prior to skimming.

And if you were to get any chunks in your mud I would hope you toss them out, not back in the bucket.

That's a good question. Would a squeegee be appropriate while it's still wet to reduce ridges?

Re: Skimming Over Spatter / Knockdown Texture Question


Yeah, what type of mud is LaFarge? I skim coat over textures all the time. I usually never have to sand down the walls unless its a really heavy texture. skim coating over a knockdown tex is easy. If the walls are really dirty(smoke stains, etc) I would at least roll on an oil based primer like Kilz. This will seal up all the stains that would typiccly bleed thru the mud and give the mud a GREAT surface to adhere to. Always 3 coats lightly sanding between coats. Ive heard of people thinning out mud so much that they can roll it on with a paint roller then coming right back and smoothing it with a knife. Seems time consuming to me. If u dont feel comfortable doing it then sub it out. 1 room isnt a big job. Definately a great chance to improve your mudding skills.

Re: Skimming Over Spatter / Knockdown Texture Question


I like the idea of rolling it on and smoothing it out. Sure sounds better then loading a pan every few minutes. This is an orange peel texture which will be a little harder than knockdown simply because the texture is more raised and will require more mud. I don't think I want to try and sand down the high points of the texture beforehand or I'll just make a bunch of paint burrs that will get in the mud while I'm trying to skim.

Keep in mind that a lot of drywall compound manufactures don't recommended
Thinning out the mud that much. It tends to shrink more and doesn't give as nice
A finish without thinning. You shouldn't have to load up your pan every few minutes.
Just use a 12" knife and wipe it on thick then pull it back off. Keep the knife tight to the
wall while you pull it back off. it will definitely take 3 coats for a great finish.

fix is right. heavy mud. you will have to apply mud in different directions for each coat. this could take 3 passes . or it could take 5. depends on the thickness of texture.

You're the first person, and probably only one of 10 on this site to get the reference. I have a big soft spot for classic RPGs
