Hey Guys, just wandering about your experience. So what kind of mud you use for Ceiling Textures: Fog, Knockdown, Orange Peal. :)

I use Fastex or Hamilton's Ready Spray for everything but skip trowel. I really like the way Beadex Light Taping mud throws a skip, but you have to be uber-careful when sanding it if you choose to do so.
we also use Hamilton redy and fastex,havnt seen fastex for a while is it still around?Tapin mud for a skip:blink: never would think to try but I bet it works fine. That beadex tapin is pretty good tapin mud. I know you dont try to spray it though

It is funny but in Minnesota there is none of any that products:blink: I use regular mud for most of my ceiling spray (cheap way) but for fog powder ceiling spray must be better (not too good for sanding).

The only problem with using normal mud is that it yellows over a short period of time. Its like boarding a basement and not painting the drywall after its finished. Give it 2- 3 years and the drywall will start turning yellow the mud also. Drywall material has to be sealed for a lasting finish.

Unless of course you paint your ceilings last after texture is applied instead of beforehand. Then it should be ok but hard to patch if something that needs to be repaired at a later date.

My guess is that an additive is added to the ceiling texture products so that this scenario "yellowing" doesn't happen.

For a better and longer lasting finish is probably "OK" to add a small amount of "Flat" paint to the mud so that this doesn't happen. This is a suggestion (something I would try ONLY in a bind) but you are better off texturing the ceiling first then paint afterwards. Its harder to patch though if you have to do a small repair to it.

I would ask your supplier to start stocking the product needed to do the jobs properly though, nothing wrong on using normal mud ( I do not recommend it) but it sucks to seal it all with ceiling paint.

there used to be a bag mud called for kd. I believe it was usg. We switched to box spray mud and never looked back at the bag stuff. Dont spray any kd unless pathing into existing. Fastex and readyspray in 50lb box is so much easier to work with IMO

we used to mix about 3 bags of spray mud per mid size steel garbage can... quite a bit of water dont know exactly,. The smaller steel cans work better beings you have to lift them.Dont mix it xtra soupy until spray day. We would mix cans day or 2 b4 to let mud breakdown,,like I said a lil heavier mix 1rst go around. Soup it up where u want it the day u spray.

spray prices: If there is enough footage i charge a drywall contractor as low as 2 cents per foot. General contractors i charge more. If i have to wait for my money it costs more. If the job is to small i have a 150$ minimum. Unless its a remodle i charge based on how much masking. You can kill a lot of time masking a skylite. cabnets floors, If i work for a piggy contractor who didnt cover anything first, I charge alot to clean then mask. Sometimes i just leave.

Canadian powder mix

Up here we have a product called Kal-Tex which is a Synko product. Synko is CGC (Canadian Gypsum Company) and I believe a subsidiary of USG. It is likely similar to or the same as your USG product line. It also needs to be mixed and soaked for some time before using but it works well. :thumbsup: Ceilings get a coat of primer first.

Knockdown ceilings

For my ceilings I dont use any type of special bag mix.
Just regular CGC Machine Mud. I use Machine Mud for absolutely everything. Tape, Beads, Fill, Skim, Designs. You name it, Machine Mud!


Here's some pics of a house I did last week.
