Aagh! What happened to my curved wall?

May 5, 2015

Curved wall seamYou’ve laid out the prescribed radius, installed your top and bottom tracks, positioned your studs and applied your gyp board over this fine-tuned edifice. Everything is absolutely on the mark and ready for the taping mudders to do their artistic finish.

Later, when you revisit the site to admire your workmanship, you’re aghast at what just couldn’t be! A raised area like a speed bump right up the middle of your convex curved wall! How could the tapers do such a terrible job? Now the only thing left to do is have the tapers float out that ridge to try and hide it. But you’re afraid you’ll always be able to see it. And even worse, what if the architect or customer notices it?

Well, I hate to say it, especially to such an artisan as yourself, but this problem arose as a result of something you didn’t anticipate or fix. The time to prevent this problem was way back when you were covering this wall with gyp board.

We all know what a challenge it is to get gyp board to bend to a radius, even when you wet the back or use a high flex version. As long as you have a large piece to manhandle, you’ll have enough leverage to wrap it around the proper radius. But at the end of each sheet, when you’re making a joint or a butt joint with no bevel, you just don’t have any leverage to get those last few inches to curve like the rest of the sheet. So when you screw down the edges on the stud at the joint, even though you’ve screwed them down tight, they are going to pull so hard on that stud that they create a ridge.

On such a surface that blemish will shine like a gold tooth. There’s a really simple way to avoid this. When you reach the end of your sheet of gyp board, add a stud laid flat behind the joint. If you have room, a 6” wide stud is even better than a 3 5/8”. Now, when you screw the edges of your gyp board to the middle of this flat stud, it will force the ends of your gyp board to curve in, just the slightest bit, to create a little recess for the joint. And you know your tapers are able to fill that easily.

So rather than the speed bump, you can have smooth sailing as your eyes cruise across your curvy gyp board highway. The main trick is to remember to do this as you are installing the gyp board. Otherwise you’ll be groaning later, as you view the imperfection. Remember, we’re here to make you look better!
