It is very easy to coat enamel paints with acrylic paints but you really should pay attention to a couple of points if you want it to be successful. Always sand the the enamal well and fill any holes with lindeed putty then apply a good coat of undercoat. I use an oil based undercoat first and then several days later sand the undercoat lightly and coat with acrylic all purpose undercoat. Once you have done this you can apply acrylic top coats. If you are using a self priming type acrylic paint on external work, you could skip the acrylic undercoat and apply it straight on to the oil based undercoat but you must leave it for several days to dry completely before coating with acrylic. I have used both methods over the past 5 years and both have not shown any sign of problems to date.
yes
Yes, you can.
If you are painting a residence the chances are your enamel is a water borne acrylic enamel. Conversely, if you are referring to acrylic and enamel spray cans then the answer is yes you can spray one to another without any problems. Always be sure your paint is completely dry before applying successive coats.
No, you can't.
Well, honey, technically you can spray enamel paint over acrylic paint on a car, but it's not the ideal scenario. The two have different properties, so the enamel might not adhere properly and could lead to chipping or peeling. If you want a paint job that lasts, I'd recommend sanding down the acrylic paint before applying the enamel.
Flashing occurs when a surface has not been properly sealed, so a latex acrylic primer applied over the surface first will keep an eggshell enamel paint from flashing.
Enamel is a word used to describe a finish, not the formulation of a paint. It simply means a hard reflective surface. Many people mistakenly use the word enamel when referring to oil based paints. So. if you are asking if you can paint latex or acrylic paint over a latex or acrylic enamel the answer is yes, however, I strongly recommend you sand the old paint first to give the top coat "tooth". If you are asking about painting latex or acrylic over an oil based paint the answer is still yes, however you must first sand the old paint and apply a good quality primer to it. Check with a reputable paint retailer for the best brand in your area.
If the base coat used in your project is water base then yes, you bet you can. If there is any chance that the base coat used was an oil base paint then you cannot paint directly over it. The acrylic enamel will not adhere to the oil base paint and will begin to peel off as soon as it is dry. In which case a coat of primer is in order.
you can paint over latex paint with latex enamel.
Acrylic, like enamel paint, can be matt, gloss, or satin finish. Please see the related link below.
If the Enamel is an original baked finish there should be no problem. Many DIY touch up paints are made from Acrylic Lacquer. If however the enamel is air-dried then the solvents in the lacquer will react and cause the enamel to bubble and craze. Enamel paints become hard on the surface but stay soft underneath if not baked to harden them. The lacquer is able to penetrate this outer layer and react with the enamel paint.
Yes, enamel paint will go over flat paint.
