Answer 2

You're going to have to prime over the gloss paint before applying the satin paint. If you don't, the stain paint won't stick properly and will end up peeling off.

If in doubt whether the gloss is oil or latex based, just use oil based primer.

Answer 3

With all due respect to you and others who have answered, I offer this. No ego involved.

I've applied thousands of gallons of paint, and Primer is often valid, but not strictly neccesary in the industry.

I just applied KILZ for the purpose of covering water staining. It was OIL based. After, I painted a LATEX satin, and it worked fine.

The issue has little to do with the SHEEN of the paint,,, as the properties of a paint from flat to gloss, in a latex, only means that more polymers/ gloss substances have been added to achieve various levels of finish.

Certainly you might expect to paint 2 coats of the finish coat, but you might have to do that over a primer anyway. Actually the fact that a gloss or SEMI, over any finish almost always requires multiple coats, not always the other way around.

Besides all that... To use the finish coat as your PRIME allows that you're merely covering the desired color with another coat of the same, not trying to cover a White, or other primer base color.

Answer 4

Prime it with a good quality primer. You do NOT need to sand it. Do not waste your time. Once you prime over the current coat, you can paint over with satin paint of any kind. Valspar is recommended as a paint brand, as they provide thick coverage.

Answer 5

You have several choices:

1. Sand the glossy area prior to painting
2. Apply a liquid deglosser to the glossy paint prior to painting
3. Use a primer which is formulated so that it can be applied directly to the glossy paint.

Answer 6

lightly sand, apply primer (kilz, flat wall paint, etc) let dry then apply 1-2 coats top coat with a satin finish

Answer 7

wash with TSP it will clean the surface and take off some of the gloss
