Lighten up ********.
Aw shucks! I don't mind...
I'm certainly not the best painter here on Painttalk.com from looking at the awesome pics of workmanship I've seen. I really enjoy all the great posts and hope to learn new things from them. Perhaps one day I'll be up there close to all you guys with REAL talent. :thumbup:
Me? I'm a mechanic.
I get the right tools and try to use the best methods to get the job done in the most cost efficient manner to provide the end client with a quality product in the shortest possible time.
Difficult for me to think of circumstances where painting should not be done from the top, down.
Of course 18' high cut in has to be done off an extension ladder...
And a weinie roller might be good to feather that into the body of the wall.
The bulk of the wall should be done with a production roller on a suitable extension pole.
The less time anyone can spend on a ladder, the better off you are.
Saving grace of this situation is that unless there is a set of stairs or a mezzanine across from this high wall, some minor indisgression in coverage will probably never be noticed.
I NEVER paint across a wall that was rolled vertically with the first coat.
If there were lap marks the first time, you'll end up with plaid the second!
An oblique angle is superior, in my opinion.
