I put mud on the walls in heavy globs and then used a large mud trowel to spread it flat. With spaces between the globs of mud, then spreading with the trowel it caused recessed areas where the mud didn't cover. I wanted those because the glaze sinks in and is darker in those spots. I then used a fine grit sand paper (600 grit) and very lightly hand sanded the wall just to smooth trowel lines flat.
Then we rolled the walls with Behr flat bright white (same as ceiling), we rolled the walls and ceiling at the same time.
Note: I was told to use at least a semi gloss on the walls under glaze because the glaze becomes harder to work with on flat paint. But with a semi gloss not much of the glaze actually sticks on the base coat so the paint ends up looking a lot different.
It is difficult to glaze over the flat paint. I had to start and finish an wall very quickly before the glaze started drying. Once I started a wall there was no stopping.
The glaze is Behr Premium Plus Faux Glaze. You pick out the color of paint you want, just regular Behr satin is what I got. Mix 1 quart of the paint to 1 gallon of glaze.
Then I tore up sheets and with a pile of sheets in one hand and the glaze and brush in the other I'd paint a 12"x12" section with the glaze and rub with cloth to take the majority of the glaze off leaving more in the recessed areas. Then the next 12"x12" spot and so on and so on. It does take practice to know how much to rub the wall. I have done our entire house like this so by the time I got to the addition it was second nature.
Then hang the painted molding, caulk and touch up the nail holes and Bobs your Uncle
Here are some pictures.
This is a picture in the walk in closet of the new wall and existing lathe and plaster wall next to it. Shows the mud pretty well.
Here is a close up of the bathroom wall. once done. I did a beige color in the bedroom and hall and a green in the closet and bathroom. I used medium toned colors for the glaze over the white paint.
And here is some more photos I found showing the mud and glaze.
