Special tricks for Stomp/knockdown

Fergafinish

Was wondering if someone could give me the lowdown on the stomp/knockdown texture. i.e. mud consistancy ect.

Darren@Partners

Will need more info from you as to what sort of equipment you're using to spray your KD and how heavy a KD you're after.

As to the stomp, for ceilings you thin your mud to slightly thinner than finishing, though you'll have to guage this yourself as to how deep a texture, type of brush, etc. Usually we use a #3 washtub and a double crow's foot in the field and a single in corners and around edges. the mud should hang like icicles when you pull the brush away. once it has set up a little we knock it down with a paddle and let it dry. Usually have to sand the surface the next day to get the look right.

I helped a guy do knock down once. We srayed a couple of cielings, sat down and had a beer, cheaked the cielings, not dty enough yet, had an other beer. Let me tell you, that was a long day.

I tell you hwhut!
What's a cieling? how do you cheak a cieling? I tried looking it up on wikipedia, came up with nothing. Help an educated male out, please? Maybe I'm just too dty :smileythatspitsincan:

Darren@Partners

Whitey, Surprised you haven't spell-checked that cody guy yet. I've just been waiting to see your reaction. He's been up on CT also. Jeez it's horrible, it'll make your day.

I'm going to have to look for that one. I haven't been on a whole lot lately, so I think I've missed a bit. I have however noticed all the proper grammer and puncuation since I've gotten here. I'm so proud of you guys!

From my experience, its mostly the brush, If your brush is brand new, its not going to make the same design 5 houses later. Try to keep your mud as consistant as possible, he explained how to mix it, and its personal choice, whatever works best for you.

Great explanation though

I did a trowel stomp today (at the homeowner's request, no less!), but I added a few twists to it.

One, I used Beadex light topping because that's what I had in my pan when I made them the sample. Two, I stomped it out with a gum rubber float. The topping rounded itself off as it started to dry, the same effect as using loose mud on a slap, but with more visual interest. The gum float was used because the ceiling was a little on the wavy side (furr and rehang on a house built in the 40's) and I didn't want to gouge any edges pounding on the lid. All in all, a nice, albeit slightly more time consuming, alternative to traditional slap with a brush.

wow I've been doing that stomp thing wrong this whole time. I always roll mud on ceiling with 3/4 inch nap roller or spray mud on ceiling and stomp with a double crows foot if your mud is wet enough it rolls right over and your done. If your talking about knocking down your stomp texture (I call that hillbilly lace) you would just leave mud thicker when tacks up knockdown.

SlimPickins

There's your problem right there....you're supposed to be using 13/16 inch roller.....der!

(I prefer the 1-1/4 roller for getting texture mud on the surface).

I find a nice even coat with no stalactites works just fine for me looks subtle and consistent. 1 1/4 roller is overkill it is all about the mud thickness.

SlimPickins

Except the 1-1/4 puts more material on the wall, and then you can spread it out however you like. I'm not trying to convince you of anything here.

we just spray our mud on then stomp,, one thing is to make sure both brushes are the same brand some brands look a little different in the middle of the brush.

Bevelation

Here's what I do:

Keep the mud thin; almost runny....borderline.

Use any all purpose or finish mud. It doesn't have to be texture mud.

Give it 15 mins to set before you strike it. Use the excess on your trowel/knockdown knife in the angles to fill the texture into missed spots if you're using a round stamp.

Come in next day and brush it with 150g paper.

you guys use brushes?

I just use the back of my hand...spread your fingers slightly and kinda back hand the ceiling....about the same power and consistency you would to your 2nd wife's red headed son.....you got to move pretty fast though because once your hand starts to swell the pattern will change slightly and it is a pain to keep consistent.

I felt like a laugh this morning..not enough coffee or something and a late night figuring a proposal for a job that I will probably be too high on...one of those moods today

I usually just use a round brush unless I am matching a crows foot...seldom used here...If I have regular walls I roll unless it is big or if I am doing a l5 for dens then I spray it with the texture at same time...been doing a lot of basements with dens lately..I use a warner or magic trowl to knock down...wait till the tips start to flatten out in sheen and its ready to kd

Mark 5 sprayer works the best or a 3/4" roller. I like to mix proform all -purpose like primer for the sprayer , for the rolle it should be lie angle mud. soak a clean crowsfoot brush in water and shake appl mud evenly as posibble some where close to an 1/8 to a 1/4. ad a small amount to the brush, don't like cicles hanging from the ceiling. just get a nice lacey print, when knocking down I use a plexy glass paddle you want to hea r a slight bitt of drag. this texture is highly prefered when shown a sample then do the talking. everything takes practice,and a good teacher, lots of drive , and dedidcation. looks realy nice with semi-gloss on it.

years ago ,,way back,,, and about the last time I ever used any type of brush to texture with,, the man I was working for at the time ,, Used his spray rig to shoot the mud on.. I had to run like hell with the double brush to keep up , Turned out super nice on the finish

DSJOHN

When you buy a new brush--soak it in a bucket of water for a day -then the next day take it out and set it on a flat surface and put a heavy weight on it to flatten out ,that will keep it consistent so it doesnt start small and end up big!!!

Oh yeah...those were the days alright That's hard work on a summer day with all the windows sealed up tight. So much moisture your cigarette goes out
