Trouble getting clean lines on knockdown texture


We bought a house with knockdown texture on the walls and ceiling and no matter what I do I can't get a clean line between the wall and the ceiling. We have green walls and a white ceiling and we can't get a strait line. I have tried different painter's tape and it always bleeds under the tape because of the texture. Any ideas please?

This is just one of those things that takes practice. Some say to take a stiff putty knife and score a line between ceiling and wall. This provides a "valley" for your paint brush to follow. I've never tried it, but many swear by it. Textured ceilings do make it tough even for us pros but there is a relatively straight line near the ceiling that, with practice, you will be able to hit every time.

Personally, I'd suggest getting rid of the masking tape. To cut a straight line, even on a knockdown surface requires a steady hand, a good brush, a decent quality paint, a sharp pencil, patience, a little practice, and a few choice expletives (to have ready in case of need).

My recommendation is to obviously paint the ceiling first. As you trim the ceiling, make sure you have ample paint into the corner where wall and ceiling meet. Bring the ceiling paint down onto the wall about an inch or two - then allow a couple hours to dry.

Next, take your sharp pencil and lay flat against the freshly painted ceiling with the point against the soon-to-be-painted wall. With the pencil flush against the ceiling, lightly strike a pencil line all along the wall(s) to be painted (you may want to wrap your pencil in wax paper to avoid, or minimize any scuffing of the new ceiling paint...otherwise, you may have to touch-up a few areas after walls are painted). This creates a perfectly straight line, in line with the contours of the ceiling, to cut against using your wall paint.

Choose a HIGH quality angle, or flat, sash brush (preferably 2.5") capable of, with proper technique, cutting a razor straight line against the pencil marking (Most people, it seems, prefers an angle sash brush - I prefer a flat sash, but then I'm left-handed)...(not that being left-handed necessarily matters, but it's the only reason I have for preferring a flat sash).

This method creates about an 1/8" edge (drop) from the ceiling which creates a distinctly professional finished appearance. IF, after painting the walls the pencil line is still visible, wait a few days then lightly rub the exposed pencil line with a kneadable eraser. IF, after painting the walls, any scuff marks (from the pencil) are visible on the ceiling, simply touch-up affected areas with ceiling paint and - "voila" - a neat, professional looking paint job with a perfectly straight ceiling trim.

If it is really ragged and bothers you after all attempts mentioned? You might think about installing some simple traditional picture frame molding to transition between wall and ceiling. Caulk it, prime and paint it, and then cut in ceiling and wall to it. Of course trim may not look right in a contemporary setting.

Run a bead of caulk in the angle - finger-smooth it.
Paint the ceiling cutting into the caulk and slightly onto the wall.
Paint your wall, cutting a line that looks straight when viewed from a reasonable standing or siting distance.
