Use Paint Roller to put on 3rd coat of mud question...

KUIPORNG · 02-09-2007, 09:48 AM

I saw the book recommend to use paint roller to put on the third coat of mud on to seams... I would like to do that, rather than using tapping knife... Last night, when I play badminton, I have to hit net balls 90% of the time rather than back court long drive because of my tire arm due to mudding... that give me another good reason to use the paint roller....

my question is: if I do that, how thin should I make the mud be... I can see for this to work, the mud should be pretty thin... but the book said just add a little bit of water.... I wonder if the mud is not thin enough, would the paint roller work.... the book said after put on the mud with paint roller, use straight head to remove most of the muds to leave a finishing surface....

any advice...

might as well ask my other question... for mixing all purpose muds... I didn't really clean the mixer every time... I just soak it into water and turn on the drill to rotate it a bit and take it out... don't even bother cleaning the stuff stick on it with tissue paper... why... cleaning that thing is a pain... and I find out it is ok with those dryed compound on the mixer to do another mix... doesn't really affect the quality of the mud, (not noticable to me at least).... anyone agree/disagree of this....

I know that the idea of the paint roller application is so that you will get an 'even' wide consistent coat of compound. This is not always an easy thing for a DIYer to accomplish if they have minimal experince with taping/skim coating...& taping tools.

As far as the compound mixture for the 3rd coat:
We mix the 3rd coat compound so that it has the consistency of soft yogurt.
The 3rd coat is supposed to be the thinnest coat you put on. It is supposed to be wide and only about 1/16" thick. This really is the hardest coat to do right. (This coat separates the people who think they know how to tape, and the real experts)

Don't fret... just practice, practice, practice....

As far as the cleaning of the mixing paddle. The reason we like to clean it spotless with a brush is so that the dry crums don't contaminate the nice smooth batch of new compound. Little dried crumbs will leave long streaks in the coats of compound ...

Thanks for the reply AtlanticWBConst.... Just want to clarify with the paint roller stuff a bit more... the book said just use it to apply it on the wall, still need to use knife to wipe it through.... Does that change your mind of using it being difficult...?
