a painting question.
painting a ceiling this is on smooth surface. i used a ceiling paint pittburgh
after i was finished i could see paint marks where i started and stoppedwhat is the reason for this i used a 10 ml roller i went in a straight line. any help would be wonderful thanks
Use at least 13mm up to 20mm. That converts to 1/2" up to 3/4", roughly.
Standard painting procedure calls for keeping wet edges. As you can see that isn't so easy on a ceiling. So, go with a larger roller, use plenty of paint and keep wet edges. Try to roll from wall to wall without stopping and on the final strokes use light pressure to even out roller marks.
Hope this helps.
Top three reasons for roller lines are
1) Cheap Paint
2) Cheap Sleeves
3) Poor Technique
So...I don't recall using Pittsburgh Ceiling Paint before, but I have used the Manor Hall and Speed Hide products, and can't say they weren't just fine if not excellent products
I suspect the ceiling product is not a poor product
You should be using a good quality roller sleeve, at least a Purdy White Dove (or similar) or even a 50/50 wool/poly...a one dollar sleeve just won't cut it
J.Who's suggestion of too short a nap could also be a factor...I'd step up
As for technique, a common problem is people trying to squish all the paint out of the roller-every last drop, rather than applying the paint (especially when using a too small nap and/or cheap sleeve)
The idea is to lay the paint down, not squish it out of the roller sleeve like wringing a mop
I don't know what you mean by "straight line" but it doesn't sound good
You should be starting in one area, then moving on the the next while the edge of the painted area is still wet (maintaining a wet edge)
If you are going the length of the room/hall with each pass, that is improper technique
Perhaps you over-rolled every rollerful of paint, stretching it out to where it was too thin, particulary at the finishing edge. Then when the next rollerful was put into place, the leading spot naturally had more paint than the finishing spot of the previous rollerful.
