I wish I knew about this painting trick before (cutting in straight lines)

[glenimp617]

So basically someone hadn't painted a straight line when doing the curved part of the ceiling originally?

I would have painted the ceiling down on to the wall without masking tape to start with. Using the masking tape to begin with creates a shunt where you have a difference in paint levels where the masking tape is occupying. Not using the masking tape to begin with means you only end up with one shunted edge on the wall. If you allow the ceiling paint long enough to cure you can then take that shunt out with a fine sand paper. Then use the frog tape yellow or similar to create the new line that the wall should finish to. Always remove the masking tape whilst the paint is still wet otherwise the paint may crack other than on the line of the masking tape and give a rough edge.

The painted surface that you apply masking tape to needs to have had several days to cure properly before applying tape to it otherwise you risk pulling the freshly painted surface off.

That's exactly what I did do The white of the ceiling went down onto what was then magnolia

But you got white on top of the tape or is that magnolia that you were going over the green with?

What I did was paint the entire ceiling, taking it quite far down the wall. Stuck the tape on, sealed the edge with white, then painted the walls green. Did two coats and looks damn good.

Due to the height and stairs, I had to use a roller with a long pole. To put the tape on, I used some ladders, and very dangerously spread myself across the ladders, wall and bannisters at full stretch to just about get the tape on. Fortunately I didn't fall off.

The bit I don't get is if you painted the whole ceiling and then put masking tape on, why you then needed to apply more white paint rather than at this stage start with the wall paint?

I think you've missed the entire point of this thread

He hasn't. The method shown has an extra step of applying a coat of white paint after painting the ceiling and applying the tap. That extra white paint is not required with good tape.

I beg to differ after getting bleed using both tessa and frog. The seal method has for me at least, resulted in 100% bleed free time and time again

Don't get me wrong, both those tapes are very good....but neither are perfect

Ah OK, I haven't had bleed issues but fair enough if you have and it helps. But the overall point of thread is using tape vs. free hand surely? Not this extra use of white paint to seal it?

No that was the point I sometimes wonder if the actual paint itself plays a factor in bleed. Obviously if the wall is rough and you can't get the tape super flat, but maybe some paints seep worse than others.

Thinking back, the main culprit was when I was glossing, and the gloss I had at the time was like water. I know gloss is runny at the best of times, but this stuff was literally like using water.
