Should You Prime Drywall Before Painting? Truth Revealed!

Many homeowners ask, “Should You Prime Drywall Before Painting?” Many painters would have suggested primer almost every time you painted in the past. However, many more excellent and efficient paints are available nowadays, so priming is not always necessary. So, Should You Prime Drywall Before Painting?

The answer could be a little difficult. Applying a primer in some interior settings may be wasteful and unnecessary. On the other hand, skipping the primer might sometimes end up costing you more in the long run since you might need to use more coats to get the appropriate coverage and appearance.

Should You Prime Drywall Before Painting

Yes, generally speaking. Before painting drywall, you must first get a base coat of the proper primer. By priming the drywall, you can guarantee that the paint clings to the surface correctly and that it won’t peel off over time.

As drywall is quite sensitive to moisture and temperature, it will also prevent the paint from breaking if there is a substantial change in the environment or temperature.

Even if there is an existing coat of old paint on the surface, you should apply a primer the first time you paint drywall and again every time you repaint. This is so that the paint has a strong foundation to maintain a good hold even when the temperature changes.

However, priming your drywall isn’t the only preparation you should consider before painting. Before painting your drywall, you must do the following tasks:

  • Verify that the drywall is in excellent shape and has an even, smooth surface. The drywall may have dents or gouges, so you will need to patch them up using a paste solution like drywall mud.
  • Please ensure the drywall surface is smooth and even by using a pole sander to sand it down.
  • Sanding dust must be removed entirely. You may utilize a vacuum cleaner’s suction for this.
  • Clean the drywall’s surface thoroughly. For this, it would help if you used a sponge or towel dipped in a solution of white vinegar and water. This is a gentle way to clean the drywall thoroughly.
  • Dry out the drywall. The paint will be more prone to peeling and cracking, which is not ideal if there is any moisture or humidity present when you begin painting. Give it ample time to completely dry, then!

Once you’ve finished the aforementioned processes, it’s time to prime the drywall with a base coat. This step is essential because it will make the drywall more robust and resistant to fluctuations in temperature or moisture, as well as guarantee that the paint adheres correctly.

A high-quality acrylic latex primer works best on drywall. However, it would be advisable to use a stain-blocking primer if you were repainting the drywall instead of painting it for the first time.

When Should You Prime Drywall Before Painting

When Painting Over A Glossy Surface

Paint does not adhere well to glossy surfaces. If your wall has been shellacked or painted with a high gloss or enamel paint, you may apply coat after coat, which will never stay.

Before applying primer, some surfaces may need mild sanding or polishing. This will guarantee that the surface of your walls has enough texture for the primer and paint to adhere properly.

When You Have Wallpaper

Whether your wall has some flaws from wallpaper removal or you want to paint over existing wallpaper, you should use a primer. Each of these surfaces is rough and would benefit from the primer.

The Surface Is Porous

Priming a porous surface, such as unstained or untreated wood, is always a good idea. It is porous when a surface absorbs water, moisture, oil, smells, or stains. Newly placed drywall is also very porous, but in two ways: the naked facing paper and the dried joint compound covering the seams. If you don’t prime beforehand, these porous materials will soak your paint straight into the wood or drywall.

Also, if you have patched or restored drywall, the surface will most likely contain spackle or joint compound spots. If these patches are minor, there is no need to purchase a second primer. You may softly brush a little quantity of your usual paint on the places you just fixed. When the places are completely dry, you may paint the wall usually, and the areas you worked on will not be visible.

You’re Painting On Top Of Metal Or Plastic

There is a primer particularly designed for metal. It will guard against corrosion and act as a solid base for any further coats of paint. A primer made exclusively for plastic is also required. Apply even quantities of primer to the totally sanded, clean, and dry plastic surface.

Color Contrast From Dark To Light

Consider brushing a soft lavender paint over a dark green hue; you’ll immediately learn that priming over the dark color is required when creating a dark to light transition. When covering a dark layer of paint, you may need a tinted primer to make the new color seem more accurate to the color swatch you’ve selected.

Walls That Have Stains Or Odor

Before painting, scuffed or discolored walls might benefit immensely from a coat or two of primer. Some stains, such as crayon scribbles or grease patches, can show through freshly painted surfaces. Surface defects may also show through a lighter shade of paint, so applying a primer is worth your time if your walls have a few flaws.

However, do not use a primer to hide mold or mildew on your walls. It will only become bigger. First, address the source of the mold and eradicate it. Then you may start priming and painting.

What Paint Do You Use On Drywall?

Knowing which paint you can use effectively if you wish to paint your drywall is crucial. There are several paint varieties that you may use on drywall. However, acrylic latex paint is the ideal kind to utilize for the most excellent outcomes. The results will be the smoothest and most expertly done since they will stick to the surface the best. Not to mention, it will be the simplest to apply correctly.

If you are painting the drywall for the first time, a premium acrylic latex primer is ideal. Suppose the drywall has already been painted, and you are effectively repainting it. In that case, you should use a stain-blocking primer since it will also assist in erasing scratches and other flaws, making the finished product seem as smooth and expert as possible.

What Happens If You Don’t Paint Drywall?

As a general rule, it is preferable to paint drywall since it isn’t nearly as durable as plaster or other interior building materials. It won’t be as strong or resilient and be as well-protected from weather elements like dampness and others if left unpainted. Additionally, painting the drywall will give it the distinctive aesthetic for which it is renowned!

To get the most outstanding and professional results, you essentially need to apply the right primer, roughly two coats of paint, and a sealer. Your house’s drywall will appear much more excellent and be more resilient and protected if you do this.

Is Drywall Primer The Same As Paint Primer?

No, drywall primers and conventional paint primers are not the same; they vary somewhat. The primer for drywall will be made mainly to stick to the drywall surface, almost like glue. It then smooths down the surface so that paint can attach to it more easily and adds a layer of protection to the drywall to make it more resilient.

Conclusion On Should You Prime Drywall Before Painting

Nobody is prohibiting you from painting right on the drywall, technically. But it’s not going to work. Drywall requires a foundation coat of primer for the paint to adhere correctly. Thus, the paint job will fail if it is not appropriately applied.

If you do not prime the drywall before painting it, the paint will not adhere correctly, making it far less durable and perhaps peeling. Also, unless you apply a primer first, the paint will peel off the walls in humid weather conditions. Therefore you must do it! I hope your question about whether should you prime drywall before painting has been answered.
