Clear primer.
LOL...no sorry, it will just be a bit shinier than anticipated. (gloss is quite scary if painted over an entire wall - better for trim and cabinets, etc)
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).
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.
Yes, you can generally paint high gloss latex over flat latex paint. But you must do all the preparation work in the best tradition of any professional painter. All "flaking" must be removed and the raw wood primed. This will present a "smooth" surface for the new coating. Additionally, everything that is to be painted my be scrupulously clean and free of anything that will restrict the new latex from sticking to the old.
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.
Can I paint semi gloss over flat paint? Thanks!Barbara Phillips
Yes, you can paint flat paint over satin paint as long as the surface is properly prepared and primed.
Yes, you can. You can always paint over with same paint.
No, you don't have to - satin black will work well on its own. Another way is to paint the car gloss black first, and this will highlight any imperfections in the preperation. When you have repaired and repainted the problem areas (in gloss) , the whole car can be wet sanded with 800 grit and finished in satin clear, of the same type, (and preferably brand as well ) as the black base-coat.
It won't adhere properly if you do. You'll find it peeling of almost as soon as it dries.
Your repair will depend greatly on the type of paint used. If a flat paint was used you can simply use joint compound over the unsanded area, sand, prime, and repaint. If a satin, semi gloss, or gloss, was used then more than likely you will have to remove the paint and then sand, prime, repaint. You might be able to get away with simply roughing up the paint and then putting down joint compound, then sanding and repainting but in my opinion that is a bigger risk than it is worth.
