Your best bet is to phone your local Home Depot or Lowes, and ask someone who works in the Paint Department!
Doesn't the amount of varnish in the paint make the difference?
There are flat paints that are made to go over semigloss paint. Many inexpensive flat paints will peel almost immediately when laid over semigloss. The most common solution is to roughen the surface of the semigloss (sandpaper, sandblasting, steel wool, or trisodium phosphate). The actual requirement is to remove alkyds which migrate to the surface of some semigloss and gloss paints. The alkyds make it impossible for latex or acrylic to bond to the surface underneath. You also have to remove buildup of dirt, mildew, etc. Most primers are suitable for recoating semigloss. Read the label. A layer of primer followed by your flat paint is generally the best solution if the surface is relatively clean. Benjamin Moore Fresh Start interior / exterior acrylic primer is one example of a good primer for this application.
If you mix a flat and semi-gloss 1:1 you should end up with a paint in the eggshell range. Mix the same paints 1:3 and you should end up with a satin. Experiment with small amounts to get the desired gloss.
If it is flat paint, you can apply the texture without any additional preparation. If it is a gloss or semigloss, you will need to rough up the surface with sandpaper first.
Yes, significantly. Try mixing different amount of each until you create the sheen you were looking for
Yes, you can paint an eggshell finish over a semigloss finish, but proper preparation is crucial. First, clean the semigloss surface to remove any dirt or grease, then lightly sand it to create a better bond for the eggshell paint. Finally, apply a primer if needed, followed by the eggshell paint for optimal results. This process helps ensure good adhesion and a smooth finish.
Latex and acrylic (both water-based paints) do come in a semi-gloss finish.
Primer for the 1st coat. Have it tinted with color you plan to paint to make application of paint go faster. You may get away with only painting one coat if lucky!
You can purchase a semi-gloss enamel in both water and oil-based varieties.
Yes you can, just clean the old stain with steel wool or fine sandpaper before you do.
Exterior semigloss paint is designed to resist moisture and withstand harsh weather conditions, which helps protect surfaces from damage. Its sheen reflects light, making it more resistant to dirt and mildew, and easier to clean. Additionally, semigloss finishes provide a durable surface that enhances the appearance of trim and other architectural details. However, improper application or exposure to extreme conditions can still lead to issues like fading or peeling over time.
Yes, enamel paint will go over flat paint.
