It depends on the surface to be primed. If it is a good surface such as one that has already been painted and is in good shape, there may be no need to prime. Bare metal would require at least 2 in most cases and sometimes more

∙ 13y agoIt's going to depend on what your starting surface is. Usually a single coat of primer should be fine unless you have a very very strong color being covered by a very light color. Another exception would be if you are painting red over new drywall. Red has very poor covering ability (because if you mix any white base into it it becomes pink.) In that case I would use (and have used) 2 coats of primer tinted with red then go over with the red paint.

How many coats of primer do you need to use over black gloss before you paint it white?
If your gloss white is good quality, then a single coat should cover a grey primer.
Can you use a grey primer then paint white?
Besides a few shades of black, white primer will reflect more light back than a gray primer under a paint color that doesn't cover well. Gray is often used under dark reds which would normally require several coats of paint to cover, The lighi that would normally be reflected from a white primer underneath the paint is, instead, absorbed by the gray primer, giving the illusion of an opaque surface. White primer is used under any light paint that covers well. It can also be tinted to the color of many off white or pastel wall colors to help ensure coverage using fewer coats.
Should you sand before applying epoxy over oil based paint?
You should remove the oil based paint before applying the epoxy. Many epoxies will actually act as a remover when put over oil-based paints.
What causes paint to wrinkle?
Paint will "wrinkle" when it forms a skin over the base coat/primer of which it is applied. This can happen for many reasons such as the top of the paint coat drying faster than the bottom, too thick of an application of the paint, paint that is applied to a primed surface in which the primer was not allowed to fully dry. It can also occur when paint is applied to extremely hot or cool surfaces or during high humidity. Dirt or wax surfaces can also cause the paint to wrinkle. To avoid these situations, sand down the affected areas and apply a new coat of primer. Allow the primer to fully dry and repaint using nice even, light coats.
When is the best time to use primer Before you paint or after you paint Does it depend on the color that you are going to use or what color you are going to paint on?
Before you paint you should always prime and what type and color of primer to use changes by situation. Three types of primer to really think about. There is water/latex based which is used mainly if you are doing a color change. Oil/alkyd based paints is used for covering stains such as water, grease and smoke. If you use water for stains the stains bleed through and if you use oil for color changes it takes a few coats for the base color to stop showing. The last is Shellac which I've never used but have been told it covers stains and does color changes. Now for primer color, you have the options of white, grey or getting them tinted. Most color are good with a white primer, but if they are really dark or very bright you may want to consider something ealse. Some paint colors (mainly reds and oranges) may take many coats (I've heard of up to seven) for the paint color to come out smooth and even with no blotchy spots/see thorugh if you do not use the right primer. Best to ask the person who makes your paint if it needs a colored primer. Now some paint brands recommend for the colors that need it grey primer and some recommend tinted primers. Grey can be bought off the shelf and tinted primer is made generally by adding 1/4 the paint colors formula to the primer (do not try for more, primers take color differntly then paint and it may come out too dark)

How many coats of white paint is needed to cover a dark surface of up to 600 sq ft?
The answer will depend on the quality of the paint, the coverage of the paint and the preparation of the surface being painted. The Lowe's paint calculator says primer covers 200 square feet per gallon, and paint covers 350 square feet per gallon. Assuming for a dark surface you need at least 2 coats, and you are only using paint and not primer, and not knowing the type of paint, I would start with 3 gallons to be sure you have enough for 2 coats, and then see how it looks. If you need three coats, you might still have enough.

What color polyurethane primer is good for a light color polyurethane paint?
Primer is almost always the exciting color of light gray, so if you're painting with a light color, you should stick with the gray.

Sometimes a shop will use a darker primer such as red for certain darker colors of paint so that they won't have to use as many coats of paint to cover the usual gray primer.
