Semi-gloss paint sometimes has problem sticking to walls that have a higher gloss paint type already on them. Usually, a light sanding and a coat of primer will help.
Sometimes, semi-gloss paint peels if it was applied during high-humidity weather, as it doesn't dry all the way through.
The shiny and smooth surface created when gloss paint is used does not leave anything for the new paint to adhere to. It will not stick to an ultra smooth surface. When attempting to apply a gloss paint over an existing gloss paint you must first rough up all the surfaces to be painted with 100 grit sandpaper. It dulls the sheen and gives the new paint something to adhere to. If you don't want to perform a light sanding you could apply a coat of primer to those shiny surfaces first...then paint.
No. You must sand the gloss of and them prime and then paint. Semi and High Gloss is only meant for wood not dry wall. Its the worst idea ever to put a gloss on dry wall. Any paint with an Enamel is just as washable.
Base paint is also known as flat paint, or flat wall paint, or matt paint and is a latex paint. Flat paint is just that, flat or dull with no sheen at all. Semi-gloss is an enamel that dries very hard and can be found in a low sheen (satin) a medium sheen (semi-gloss) and a high sheen (high gloss) Flat paint is usually used on walls and ceilings where as semi-gloss is used in kitchens, bathrooms, doors an jambs because it helps hold back the inherent moisture in those areas.
If you are painting over a semi gloss paint you wand to use trisodium phosphate or TSP on the wall before you start painting. This is a deglosser that will allow whatever paint you are using to adhere to the wall. tip: After using TSP on the wall, give it a soap and water wash to prevent the phosphate in TSP to cause mildew/mold damage.
Why do I have shiny spots on my exterior wall after painting the wall with behr premium plus semi gloss enamel
yes, it works perfectly, although I used a semi gloss. The paint is tougher and is less likely to soften due to moisture in the bathroom.

I would only use this paint in kitchen and or bathroom areas. Window sills are ok too.

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.
You don't need to use Semi gloss in a bedroom. A Satin finish paint would work well.
Add Flat Paint to the Semi Gloss (SG). As a general rule, using commercial "production" grade paint. If you want "Satin" and have SG. you could add 1/3 of a Gal flat, tinted to the same color. If you want SG and have full Gloss Paint, Add 1/3 of a Gal Flat, tinted the same color. The reverse is N O T true. If you want full gloss and have Flat, it won't work in my experience. Experiment on your own. Just remember its easier to tone down gloss than to add it. This is assuming the paint is still liquid. If it is already on the walls, and you want to avoid repainting. A "Matte" finish Clear Coat could be sprayed over the whole wall, But to do it "right" you would want to repaint
Because it's only intended for trim, doors, and windows, if it's used on all the wall, it will make that wall look cheap. A better choice for a wall is a washable, matte paint that will not show off every imperfection the way a semi-gloss will.
To paint over veneered cabinets in a kitchen, Sherwin-Williams puts out a paint just for cabinets that dries very hard. Ben Moore has a line also but the color choices were limited. The S-W paint also self primes so unless you have extremely dark cabinets and you want them to be very light, 2 coats should be fine.
It depends on the type and sheen of the paint. If its a flat latex then your best bet is to Kiltz the area then repaint. A semi to hi-gloss should safely clean with a standard detergent
