Here are a couple great questions from one of our readers:
What is the best way to ensure a faux finish is scrubbable and mold/mildew resistant (for a bathroom/vanity area)?
If you are concerned about mold and mildew, you will want to start the project by priming with a mold resistant primer & sealer. Some paint companies offer mold resistant paint as well.
Does the base coat’s lustre (eggshell, satin, semi-gloss) affect the visual appearance/effectiveness of the glaze?
The lustre or paint sheen does not affect the appearance of effectiveness of the glaze. But, I would suggest using a satin finish paint. It gives the wall surface just enough smoothness for the glaze to move and be manipulated easily.
Do you recommend a clear protective coat over the glaze? Does that protection affect the appearance of the glaze?
You can use a waterbased (flat finish) varnish. It does not affect the appearance of the glaze or faux finish. This can be used on murals, venetian plaster, and any other faux finish. Don’t let anyone convince you to use polyurethane, because that will yellow over time. You many have a hard time trying to find flat water based varnish, so I included a link above where you can purchase it. Click on the picture.
