Can interior primer latex be mixed with interior acrylic semigloss?

if you use primer first

Either oil or latex primer can be used over interior latex paint.

There are flat paints that are made to go over semigloss paint. Many inexpensive flat paints will peel almost immediately when laid over semigloss. The most common solution is to roughen the surface of the semigloss (sandpaper, sandblasting, steel wool, or trisodium phosphate). The actual requirement is to remove alkyds which migrate to the surface of some semigloss and gloss paints. The alkyds make it impossible for latex or acrylic to bond to the surface…

It's primer made with a latex or acrylic base. You can use any kind of paint over this.

Yes, depending on the mix ratio, you will end up with an eggshell or satin finish.

Latex and acrylic (both water-based paints) do come in a semi-gloss finish.

Yes, you can. Prime it with a latex primer first.

no you must either lightly sand the surface first or use a pretty good primer for great results.

ergh.. yeah i think so

Only after applying an oil or acrylic primer as a bridge.

Yes, primer is more designed for what it is going onto than what is going over it. Once the primer is down and dry, any kind of paint (latex, acrylic, or oil) will adhere to it

You cannot polish fully cured interior acrylic latex paint, it does not set up well enough to be polished. It is not designed for this and doing so can ruin your finish.

I would use a good primer first.

Takes a primer before.

Preferably an oil-based primer. If oils are not available in your area, then a 100% acrylic primer will also work.
