How To Cover Butt Joints On Plasterboard
Butt joints are where two non-tapered edges of the plasterboard meet. They are difficult to hide because the tape protrudes above the surface of the plasterboard.
You can avoid butt joints by using long sheets of plasterboard to span the walls and ceilings, but you will still end up with a few.
The key to hiding a butt joint is to keep the tape coat thin. Build up a layer of compound over the tape that’s thin and wide enough to blend into the surrounding surface.
TIP Mix the joint compound by adding the dry powder to the water, according to the instructions, then mix until it forms a smooth and creamy consistency.
