Yes. You can paint semi-gloss latex paint over flat latex paint. It is not advised to paint over any latex with any oil-based paint. Nor is it advised to try and paint over semi-gloss paint with any other finish without first de-glossing the finish and priming.
I M NOT A GOOD PAINTER ,I GOT PAINT ALL OVER THE WINDOW TRIM AND WALL TRIM .HOW DO I GET THAT PAINT OFF WITH OUT MESSING UP TRIM
Primers are not water proofers, in fact primers can't be left as the finish coat because they have no durability. If the paint acts as a primer how can you expect the paint to stand up as a true finish coat.
The paint finish doesn't significantly change the surface preparation necessary. If the paint is the same type (water based going over waterbased or enamel over enamel) then the preparation is simply: * cleaning, * remove loose material, * fill any holes or hollows, * sanding and * wiping, If you are changing the type of paint (eg: painting waterbased over enamel) you may need to use an etch primer to "key" the surface and give the new paint a texture to grip onto after sanding, and otherwise prepare as above.
More important is, that both paints are of the same kind (like: oil-based paint, acrylic paint, latex paint). Semi-gloss is more easily painted over then high gloss, but first better find out what the old paint layer is made of. Check with the help of alcohol - if paint comes off in any way when you rub it with a cloth of alcohol, it's latex or acrylic paint (and can be painted over with acrylics).
