How do you prep walls that have been painted with a satin finish paint if you want to paint again with a satin finish paint?
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.
What finish on frames is easiest to paint over?
If it has a matte finish it should be easy to paint over.
Can you use KIlz one coat paint over wallpaper that has a slick border in it?
You can paint over wall paper. However it is recommended that you prime with an oil based primer. Kilz Original for example. Most wall papers use water based glues for adhesion. If you put a waterbased topcoat over the the wallpaper it could penetrate the wall paper and cause the glue to release. You can use a waterbased top coat such as Kilz Casual Colors over the top of the oil based primer.
Can you use oil based urethane over water based urethane?
if you put a oil base floor sealer over water base you will find the top coat will flake and peal off your new floor. You need to wait 30 days before applying the oil base sealer to reduce your chances of peeling.
Can you put oil base poly over water base poly?
Both water-based and oil-based polyurethane will be suitable for a floor finish, but your choice may depend on a few different factors: Water-based poly dries faster, leaves a crystal clear finish, emits lower levels of VOC's (volatile organic compounds = fumes), and requires only soap and water for cleanup. Oil-based poly takes longer to cure, gives a warm amber glow to the wood, is high in VOC's (only while still wet; the fumes disappear after curing), and requires mineral spirits or paint thinner to cleanup. Some people say that oil-based finishes look more realistic and water-based finishes tend to look more artificial, but water-based may be desired if you don't want to alter the color of the wood in any way or if you are sensitive to chemical fumes.
