Oil Primer
Oil primer act as a stain blocker. If there are stains which cannot be removed then single layer of latex primer can help to cover the stain. A maximum of one more layer can be used if one layer doesn't cover it. •
Latex Primer
Latex primer has similar consistency to oil primer but although it will be slightly thinner. You have dry up the dampness on the wall. Fans will help to do it. No more than two layers should be used on a damp wall before another paint is applied. A single layer is enough for the undamaged wall. •
Tinted Shellac Primer
Tinted shellac primer has a specific purpose like masking severely damaged walls. A single layer is enough to hide minor problems, further layers should be added until smoke or water damage has disappeared. Tinted shellac primer is very good at masking smells. •
Clear Coat Primer
Clear coat is perfect for new walls. This primer is much thinner than other primers. The purpose of this primer is to create a clear surface over a wall that will help the paint to stick. To paint a brand-new wall, a single layer is enough. Primer on Dry Wall Using a quality dry wall primer may only require one coat, but 2 coats are ideal. Once the first coat is applied and dried carefully look at surface to know if any flaws or thin spots are there on the wall. A second coat covers up these flaws, as well as replenishing any primer from the first coat that was absorbed. Primer on painted wall surface Painting over an existing white paint or lightly colored varnish job usually requires only one layer of primer to prevent peeling of the old layers. The exceptions to this rule are when you are painting a light color over dark colors. For these you will need to apply two thin coats or high hide primer to bring the wall color closer to the final color.
