tomh - thanks for hearing me - give RL another try - work with it and the directions - practice - it will work and you will like it.
Steve - take a note from tomh
Renee - RL Matte has a slight sheen - and as such doesn't work well on ceilings - the sheen gives it some washability for walls - which you want- but a good ceiling paint is dead flat.
Multiple coats of a "shiny" flat on a ceiling are to be expected - the angular light that hits a cieling will reflect off of the paint - showing shadows and roller marks. Also, since cielings are generally flat to start with - they tend to be porous - you can have flashing (where the paint is uneven in sheen) due to it being absorbed differently by the porous ceiling paint that is already there.
If you have a ceiling that is difficult - ie - vaulted/multi-angled/lots of windows and other light sources supplying light from various angles - it may be very difficult to paint your ceiling at all and have it "perfect".
I am glad that it did work out in the end.
As for the Duchesse Satin - it needs a coloured base coat - like doing the other glaze techniques.
Call 1-800-379-POLO for the correct colour - they can supply it to you.
You apply two coats of the RL semi-gloss in the basecoat colour RL recommends - then apply your Duchesse Satin in whatever manner you choose.
Duchesse Satin is semi-transparent - just like a glaze - the colour is effected greatly by the colour under it. Using the basecoat will give you the result you are looking for - make sure you do a test area and let it dry - it will change greatly from wet to dry......
