What is a Drywall Primer?

Applying-the-primer-before-painting

A drywall primer is a paint product that you apply to the drywall surface prior to applying paint. The primer covers the drywall surface and seals the drywall so it takes less paint to paint the surface.

When drywall has never been painted it soaks in the first paint greedily. The primer covers the area and makes a smooth surface for the paint to be applied to.

This type of primer is also designed to help minimize flaws that may be apparent in your taping and floating. Small scratches and indentations will disappear leaving what appears to be a perfectly smooth surface.

These primers can be purchased with an oil base or a water base. The water based primers are easier to clean up after, but the oil based primers will be better at hiding things like water marks, greasy spots, or damages to the drywall.

Why Use Drywall Primer

The biggest reason for using drywall primer is to help your paint adhere better to the surface area. The primer increases the paints ability to adhere and this reduces problems like peeling and flaking. It also makes the paint look better for a longer period of time.

Another great reason for using primer is because it allows you to use less paint. The primer cost a fraction of what the paint cost. When you use primer properly you will need fewer coats of paint to achieve the look you desire. It saves you money, and it saves you paint application time.

Primer can stop mold and mildew from forming beneath your paint. Some primers even have the ability to hide water stains, or stop rust from forming on metal surfaces.

Primer seals the original surface, protecting the material and creating a better finish area for your top coat products. It hides minor imperfections and gives you a more professional looking finish product.

What about Paint & Primer in One? 

Combination paint and primer is an excellent product. It allows you to prime the walls, use less paint, and do all of the painting in less time.

If you are applying paint to new drywall or wood the paint and primer in one may not be as effective as using a primer and then covering with a top coat of paint. New wood and drywall absorb a lot of paint so the stand alone primer creates a surface before you paint.

Paint and primer combinations are great for repainting a room because the old layer of paint will have conditioned the original construction material.

Benefits of Using Drywall Primer

Applying-the-primer-before-painting

There are a lot of great benefits to using drywall primer. They include:

  • The primer seals the material so mold and mildew will be less likely to form in humid or damp areas
  • The primer creates a surface coating that hides small imperfections in the area that is being painted. If your taping and floating is not pristine then the primer will hide those flaws and make your surface look perfect.
  • The use of primer reduces the amount of paint you have to use as a top coat. Paint cost more than primer so this is a money saving features.
  • By applying primer you will apply fewer coats of paint. This can be a labor saving product.
  • Primer covers existing problems like water stains to create a nicer finish

How to Prime Drywall 

Gather your materials

  • Paint brush
  • Roller pan
  • Roller with appropriate nap, usually a ½” to ¾” if this is the first time the drywall has been painted
  • Primer
  • Stirring stick
  • Drop cloths
  • Painters tape
  • Mask or respirator
  • Ladder

Step 1: Be sure the area is well-ventilated. You need to sand the drywall so the joints are smooth.

Step 2: You need to wipe the dust off of the walls.

Step 3: Put painters tape over hinges or items that you do not want the primer to make contact with. Cover window glass, doorknobs, hinges, outlets, and such.

Step 4: Put drop cloths over the flooring and any furnishings that might be in the room to keep the primer from making contact with them.

Step 5: Open your primer container and stir it thoroughly for a period of 2 to 5 minutes.

Step 6: Pour primer into the paint pan.

Step 7: Use the paint brush and dip it into the primer to cut in the corners and around windows, doors, and baseboards.

Step 8: Use the roller to roll the primer onto the flat surface of the walls or ceiling. Light even coats are recommended. They dry faster and they stop you from having paint runs or blotches.

Step 9: When the primer coverage looks like you want it to clean up your tools, remove the primer from the room, and then when the primer is completely dry you will be ready to paint the room.

Final Word 

Drywall primer is a time saving, money saving, paint product that helps you to create a perfect finish on your interior walls and ceilings. The primer is the first step in creating the finished drywall, and the primer prepares the surface area for the paint that is about to be applied.
