The Primer Texture

The texture of your Primer determines how well it covers the imperfections on your drywall. Usually, the thicker the Primer, the better the results.

Type of Primer

Primers are not created equal.

Regular primers are designed to bond with your drywall, so you shouldn’t expect a smooth finish.

If your drywall has marks and ridges, you may need to consider the high-build varieties.

These cost more and are a bit hard to use, but they deliver the best results where extensive imperfections are concerned.

There is also the latex primer that works great to even the drywall’s porosity.

However, this type doesn’t absorb paint as good as the regular varieties.

If you are okay with the color of your plaster, you should use a sealer for your walls.

A sealer lays a clear coat that seals your wall, preventing moisture from going through the wall while making it stain resistant.

Don’t confuse a sealer and a primer as these two are chemically different, and the results are different.

Primer improves the adherence of paint to a wall, so you should expect it to stain better.

How Many Layers Of Primer Do You Need?

The number of layers necessary to cover drywall imperfections depends on a number of factors.

For starters, how bad are the imperfections? Can you first fill in all gaps so that you apply a layer or two over an even surface?

Apply One Coat Of Primer If:

You are painting a different color over a white wall. A quality water-based primer is all you need to get your wall ready for the next coat of paint.

In the above situation, all you need is something to bind the white paint to the new one while masking stains and minor patches.

If you are making a dramatic change on your wall, you should consider using a primer that is tinted with your new wall’s shade.

Get a tintable primer and try to bring it as closer to the new paint as possible.

Your local paint shop can help you with the tinting. By using a tinted primer, you can apply one coat of paint to get the results you desire. (Source)

Apply Two Primer Coats When:

You want to paint over unfinished plaster or drywall. Such kinds of surfaces have some areas that are more porous than others.

If you paint over such plaster or drywall without two primer coats, you risk having walls with uneven color.

Since the first primer coat is absorbed the wall, the second coat hides flaws while ensuring the entire surface is uniformly porous.

If You Are Painting on Unfinished Wood:

Use at least two coats of oil-based primer. Wood is highly porous, and you need enough Primer to fill the pores and ensure that the wall is ready for your paint.

Primer comes with a higher reliable content when compared to paint.

When a wooden surface is not primed properly, some of the pores will take in more paint, and the job will not be as flawless.

Water-based Primer may cause the wood grains to swell.

If this is the only option available, ensure that you sand the first primer coat to even it and take care of any Imperfections.
