Are not water based and waterborne two words for the same thing.
You can use oil-based paint pens over acrylic IF the acrylic has not been applied too thickly. You can also use water-based paint pens. HOWEVER, you cannot use acrylic over oil. The difference in how these two mediums dry and cure can make the acrylic-over-oil crack.
In interior or exterior house paints.... Acrylics, emulsions and latex are, oils, lacquers and shellacs are not. In artists' paints... acrylic, watercolour, gouache, and some water based airbrush paints are, oils are not..
Yes. Waterborne alkyds are compatible with oil-based alkyds as long as the surface is clean and deglossed.
Yes, you can
It will protect the paint as long as you use a water based varnish, never use oil based varnish over water based paint. Tip: "water based enamel= water based finish". "oil based enamel= oil based finish".
Yes, both oil and water-based polyurethanes will adhere well to an item coated with acrylic paint. If it is a polyurethane paint, dull the surface prior to painting. If it is a clear. realize that that oil based polyurethane will impart an amber hue while a water based polyurethane is crystal clear and will not affect the color.
Yes.
100% acrylic paint can definitely go over latex. Acrylic paint actually is the same thing as latex paint. Some manufacturers differentiate their products as 100% acrylic and also have a product called latex that is made of acrylic plus co binders and other additives. So while one is 100% acrylic and the other is a mixture they are both water based and considered latex.
In the past oil paints referred to either petroleum based paints or linseed based paints. Today in the USA petroleum based paints are no longer sold and it is difficult to find linseed based paints though they do exist with a small proportion of linseed oil. Alkyd paints are made with synthetic oil and are readily available and have come to be known as "oil" paint.
The Golden Artist Colours INC. has conducted testing and research on using acrylic products for mural application. The varnish for our mural was some type of acrylic. The products to be used is a two-part like many urethanes and epoxies, water - based, acrylic co-polymer.
Do you realize that you can get FLAT ACRYLIC PAINT. Flat paint refers to the gloss level. You may want Gloss, Satin, Lowsheen or Flat. Acrylic paint on the other hand refers to what the paint is based on or what binder is being used. Acrylic paint is also refered to as waterbased paint. You most likely are referring to putting flat acrylic over lowsheen or gloss acrylic. In answer to your question - as long as they are both acrylic than you will not have any problems. I am in this answer assuming that you are referring you house paints. If not than the same principle applies - acrylic over acrylic is fine. To keep acrylic from going glossy just don't polish it.
No, there is nothing for the Epoxy to bond to. The latex is creating a "bond breaker." You will need to use a water based or water born sealer with at least 20% solid acrylic. DO NOT USE solvent based sealers over latex. It will wrinkle the latex.
