What is Primer Paint: Guide to Basic Uses

Primer paint is used to prepare a surface before applying other paints. It helps keep the final finish smooth. This type of paint can be applied over almost any surface, including metal, wood, concrete, glass, plastic, tile, brick, stucco, plaster, drywall, and more. It’s also known as undercoating.

Use the paint primer to make your painting more durable. Paint primers help protect paintings from scratches, dents, and other damage caused by everyday use. This is best done after you’ve completed your work.

Paint Primer is used to apply paint without having it dry first. This makes painting more difficult. Paint Primer does not work well if applied over oil-based paints. It can be removed easily using soap and water.

You can use Paint Primer to paint on paper, canvas, wood, glass, plastic, metal, ceramic, clay, leather, fabric, plaster, masonry, drywall, cement, concrete, asphalt, roofing material, slate, brick, terra cotta, fiberglass, acrylics, enamels, oils, watercolors, tempera paints, wax crayons, chalk, charcoal, pencil, pastel, pen & ink, and many other media.

The best way I know is to apply it directly onto your chosen surface. It dries quickly at room temperature so you don’t have to worry about waiting around for it to dry. If you decide to wait until it completely dries you will still be able to work on it. Once it’s dry, start painting!

How is primer different from paint?

Paint is a thin liquid that dries to make things look nicer. Primer is a thicker liquid that is put under the top layer of paint so it looks better. It helps prevent the new paint from peeling. If you don’t use primer, your paint will peel off much faster because there won’t be any glue between the old paint and the new paint.

When to use a primer paint before painting

When you first start working on your canvas it is important to prime the surface with a thin coat of gesso. Gesso gives added strength to your paint and helps keep your paints from peeling off your canvas. If you skip the priming stage, all of your future layers will peel right off. It can take 24 hours or more to dry completely. You should always let your painting dry out completely before using another layer of paint.

Primers come in many different grades and colors. Choose one based on the type and amount of work you need to do. For example, you would want a very smooth, light grade if you plan to make only fine details on your canvas such as small flowers. A thick gel-type primer works best if you plan on making large areas of flat color. You might also choose one that has an acrylic base so you don’t end up with brush marks. Gesso comes in two types; regular and oil-based. Regular means that it is mixed with water. Oil-based means that it is mixed half with olive oil and half with mineral spirits.

What types of primer are there?

There are many different kinds of primers available to you. You can buy regular paint from your local hardware store; it is called an oil-based primer because it uses an oil base (oil) as its binder. Or you can get a special type of primer designed specifically for use with latex paint. This kind of primer has a chemical binder instead of oil. It is called a water-based system.

Oil-based Primer

Oil-based primer is used to fill small holes, cracks, and other imperfections before you paint. There are different types of oil-based primers for many kinds of surfaces. You can use it over wood, metal, glass, fiberglass, plastic, concrete, and plaster. It will also keep your surface from drying out and cracking.

Shellac Primer

Shellac is an old-fashioned way to make clear nail polish. It has many advantages over traditional enamel paint. For one thing, it won’t crack if you chip your nails. And since shellac costs less than enamel, you can get more colors at once. You use just two things besides the shellac – water and acetone. Acetone is used to thin the mixture. If you don’t know how much thinning to add, measure out 50% acetone and mix until there’s no longer any solid material left. Then add another 1/2 cup of acetone and stir well.

After mixing the shellac paint will be ready to use. Make sure all surfaces you plan to apply the finish to have clean dry smooth walls before applying the primer. Use only pure bottled spring water for application. Let the paint set up about twenty minutes after applying it. Once it hardens completely, sand down the surface with fine to medium grit paper and wipes off the dust.

Apply several coats of top coat (optional) to seal the paint finish. To remove the primer use mineral spirits or alcohol-based solvents. Do not let the solvent sit around too long because it could damage other finishes such as lacquer or varnish. Clean up the brush and rinse it thoroughly in fresh soapy water. Always wear protective gloves when using mineral spirits or alcohol because they can burn skin and eyes.

Latex-based Primer

Latex-based primer is the most common type of primer used today. It helps to keep your paint from drying too quickly and keeps it flexible so you can apply it more easily. You should use latex primer if you plan on painting outdoors because outdoor paints don’t work well without it. However, if you want to create a smooth surface, you need to sand down any rough spots before using latex primer.

How to Use: Apply latex primer by simply spreading it over the primed area. This will help to seal your walls so moisture cannot penetrate the wall and cause damage. If your house has already been painted, then you can also use latex primer to protect the old paint job.

How much paint primer do I need?

When painting a house you can use too little or too much primer. This is true whether you are using latex, oil-based, acrylics, enamel, or some other type of surface. Use enough to cover the surface completely but not so much that it drips off. If you do not want to go through the trouble of measuring out a precise amount, just add more until the brush strokes look good.

When You May Not Need Paint Primer

A primer is a thin coat of paint that is used under another layer of paint that will be applied over it to prevent peeling, flaking, chipping, or cracking. But you don’t always need a primer, depending on how your painting turns out. If there are no flaws in the finish or if the surface isn’t porous enough to absorb the paint, you won’t need a primer.

Painting your own home can sometimes make it difficult to know whether or not you should use a primer. It’s important to understand the differences between priming and painting before you start any project.


Is primer really necessary before painting?

Primer is NOT necessary to paint! A good artist should be able to paint using only raw materials (paint) and brushes. But if you want your painting to look professional and last longer than one day, it’s best to use some kind of primer. I recommend “Gel Acrylic Latex Primer” from Sherwin Williams.

Do I need two coats of paint if I use a primer?

Many people think you must prime before applying two coats of paint to wood furniture. This is not necessarily true. Primer helps protect your new finish from moisture damage. It also makes the surface ready for paint. If you do use primer, you can apply two coats at once without worrying about it being too thick.

How long should the primer dry before painting?

Primer is put over freshly painted surfaces to seal or protect them. It must dry thoroughly before you can paint again. Too much moisture will cause the surface to crack, peel off and flake off. You also want enough water so that the paint sticks to the canvas but does not run. This means less than one-quarter inch (0.6 cm) of water after the first coat dries. If the primer doesn’t dry before the next layer of paint, then the paint won’t stick well. But if you’re using multiple layers, then primers dry quickly and don’t need to be primed more than once.
