Can you apply first layer/coat right after taping ?

I just wanted to know once the tape has been applied (first a thin layer of mud then tape then squeeze out the mud) then at this point is it safe to apply the first coat or layer of mud over the taped areas ? ?Also can the ends of the tape overlap over the one which is applied perpendicular at the ends ?

Thanks

Generally the squeezing out of the mud from the joint will give you enough to make a swath across the indentation provided by the sheetrock. If not, then you can make a swipe with a 6" knife with mud across it to fill it in. Don't work the mud too much. Make your swipe and move on. I don't like to overlap tape as it can cause a slight bulge on flat surfaces. It won't hurt to cut them with flush joints to each other.

If you apply more mud before the tape coat dries sufficiently you run the danger of the new mud pulling the tape loose

Thanks Chandler, but can you tell me once the tape has been applied is it safe to just apply the first coat or layer as it called of joint compound or do you wait until the application of the tape dries and then apply a thin coat (first layer of three layers) of joint compound ?

Did you read post #3?

If the tape coat isn't dry, adding more j/c is prone to pull the tape loose!

My response was to have you make a 6" swath as you put the tape on. Not as a second coat before the tape coat had dried. Different methods, but the tape coat is done in one pass. If you only put the tape on and leave the mud there that you used to install the tape, then it should dry before you proceed with additional layers.

You should really only mud over the tape if you are using setting compound, because it sets fast. The biggest problem is shrinkage. If using regular joint compound, let the tape dry first.

Hello marksr. Yes I did read the post but obviously did not quite understand the underlying point about the tape. It does make sense if the mud below the tape is not the dry the tape will move around when the first layer or coat is applied. I missed this point. But thanks for the clarification. I can tell you I do understand it now. Thanks to Chandler and Marksr.

OK I have another question to ask of you people. When applying the first layer after the tape dries do need to apply enough mud to even out the patched area and should the first layer cover the tape so that it is not visible once the first layer or coat has been applied ?

Not certain I totally understand the question The tape will be visible after the initial coat of mud, it might be visible some after the 2nd coat of mud. Personally I'd rather have to apply an extra coat [4 versus 3] than have to do extra sanding. It's never a good idea to apply a thick coat thinking when it dries you'll sand it down smooth!

Thanks Marksr. Yes that was exactly what I meant I applied the first coat and the tap is still visible. The patch area that I am working with after screwing the patched piece of new drywall was not even around the seams all the way around. The patched area also is very small like 4" x 5" so two pieces of tape covered over the entire replacement piece of drywall.

Having all the information at once is certainly good. Most of the comments were regarding new taping of an indented joint on sheetrock. Understanding, now, that all you had was a small patch changes things quite a bit. There was a better way to make that patch without taping it, but since you have it in, using a longer knife will help spread the mud over a wider area and hopefully produce a smoother patch.
