Yes but there is no guarantee that the colour on the surface will not streak or show a different colour through. Added to this is the fact in many houses in particular there are spray polishes used. These become airborne and do make their way to pained surfaces even if you don't actually polish that surface directly. Its a safer bet with same colour paint to give it a light rub with sand paper , then wipe with a clean damp cloth and then the satin coat should adhere to a much better standard
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.
Clear primer.
Generally yes but thorough scuff sanding with 200-400 grit sand paper in required. A primer will be advise by most manufacturers as well. A gloss urethane will likely show any imperfections on the surface such as rough sanding scratches.
It is never a good idea to paint anything high gloss without sanding first. You don't need to sand clear though the old paint, but the new paint needs something to hold onto. If there is nothing but a smooth, shiny surface, the new paint will probably run if the surface is not horizontal, and then chip and flake very early on. Always run a piece of sandpaper or a sanding block, 150 grit is good, over the surface. Why do something twice?
Yes, as long as the surface is free of dirt, wax and grease, and the eggshell and satin are both the same type, ie latex or oil, then you should have no trouble at all painting a satin sheen paint over an eggshell. Also, if the base is water based and the topcoat is oil, that will work fine too.
Yes, you can paint matte over satin finishes. It is important to properly prepare the surface by cleaning and sanding it before applying the matte paint to ensure good adhesion.
Yes, you can paint latex satin over acrylic semi-gloss enamel, but proper preparation is essential for good adhesion. Start by cleaning the surface and lightly sanding the enamel to create a better bonding surface. After sanding, wipe away any dust and apply a primer if needed, then proceed with the latex satin paint. This ensures a smooth finish and enhances durability.
Yes, you can paint flat paint over satin paint as long as the surface is properly prepared and primed.

Yes, you can paint high gloss polyurethane over satin polyurethane, but proper surface preparation is essential for good adhesion. Start by cleaning the surface thoroughly, then lightly sand the satin finish to create a rough texture for better bonding. After sanding, wipe away any dust, and you can then apply the high gloss polyurethane. Be sure to follow the manufacturer's instructions for the best results.
You didn't mention whether you were using latex or oil based primer and paint, but generally the point of using primer is so that you can paint over it with any form of wall paint. Just read the label on your primer can to make sure it is compatible. On the other hand, if you wanted to paint the primer over the satin gloss, you need to sand the surface lightly to remove the sheen of the paint and provide a suitable surface for the primer to adhere properly.
Clear primer.
All you need is good preparations: sanding and degreasing.
Yes, you can paint over an epoxy floor as long as you properly prepare the surface by cleaning and sanding it before applying the paint.
No, it is not recommended to paint over drywall without any additional preparation. It is important to properly prepare the surface by cleaning, sanding, and priming the drywall before painting to ensure a smooth and long-lasting finish.

Yes, you can paint over oil-based paint with acrylic paint, but it is important to properly prepare the surface by sanding and priming it first to ensure adhesion.
