Can You Use Latex Paint Over Oil Based Primer?

Yes, you can use latex paint over oil-based primer. But first, you need to prepare your wood surface. Paint it with quality bonding primer and let it dry well. Now proceed and apply double coats of latex paint. Never apply an oil-based paint over latex.

What Is Latex Paint?

Latex is a water-based paint made from acrylic resin. Unlike acrylic paint, latex paint is recommended when painting large surfaces—not because of its fast drying time but because most people purchase it in large quantities.

Latex is suited for painting ceilings and walls. Besides, it comes in various finishes—from flat to high glosses.

You'll also find out that some oil based paints come with enamel. Usually, an additive that's responsible for making the dried surfaces harder while making them less pervious.

What are Shellac Primers?

Shellac based primers are excellent wood sealants that can prevent tannins from bleeding through the oil paint. And because of their elasticity, shellac primers are also best for plastic, plaster, and even galvanized metals.

Shellac is known as a fast-drying primer—drying in under an hour. They can help you prime your surfaces faster than latex primers. The only downside is that you'll have to use denatured alcohol to thin the primer and clean the tools.

If you have a sensitive sensory smell, you'll not love the fumes produced by the denatured alcohol. However, you can still wear your protective gear to avoid the smell because shellac primers are the best for trimming or sealing wood.

What is an Oil Based Primer?

Oil-based primers work with latex primer and oil paints, making them applicable and very flexible to various surfaces. The advantage of oil-based primers is that they are good stain killers—meaning that they can prevent stains from showing on new coats of oil paints.

These primers are usually the best for both interior and exterior bare wood as they can seal the porous wood surfaces, making the new paint coat cover almost the entire surface.

Besides, oil-based primers prevent harmful tannins, such as redwood, from bleeding through the wood surface.

Why Should I Use Latex Paint Over Oil Primer?

If you've chosen to use latex paint over an oil-based primer, please note that the latex paint will crack or not stick properly if you didn't take your time to prepare the surface properly.

So the best way to go about this is to prepare the surface before using latex paint on an oil-based primer if you want the best results—a strong, lasting painted surface.

Lightly sand your oil primer using fine grit sandpaper to make the surface smooth to enable both paints to blend. That said, below are some reasons why using latex paint over an oil primer is a brilliant idea:

1. Oil-based primers are excellent for proper sealing to allow for the entire surface covering of the latex paint layer, primarily when you use them on unfinished surfaces.
2. Besides, oil-based primers stop wood from releasing tannins while also preventing bleeding through your latex primer coat surface.

The only downside of using latex paints is that they can swell your wood grains. However, using it over an oil-based primer will prevent ruining the surface as long as you have sanded it properly.

Just to recap, always remember to prepare the surface you want to work on properly before using latex over an oil based primer. This is to ensure that you achieve the smooth and lasting finish you've always wished for.

How Do I Determine If My Surface Has an Oil-Based Paint?

It's critical to test if the surfaces you want to work on have oil-based paint. To do this, you'll need to follow the procedure below:

1. The first test is to feel the surface—oil is usually smooth and glossy, while latex possesses a rubbery finish.
2. You'll need to dip a piece of cotton wool into acetone to check the status of the painted surface—oil usually remains unaffected while latex will slightly dissolve.
3. If you've determined that the surface is oil-based paint, use sandpaper to rough the surface until the gloss has disappeared—wash and give it some time to dry.

How to Paint Latex Over Oil Based Paint

Step 1: Get Your Workspace Ready

You can't start priming surfaces without first preparing your workspace. If you want your surface to be primed successfully, you'll need:

A well-ventilated work area—protect yourself from fumes and open the windows and doors for cross-flow of air.

Your protective gear (mask, gloves, coveralls) to prevent inhaling the fumes or getting exposed to hazardous materials.

A large, flat surface on which you'll prime your surface—this should be a spare section of the wall or ceiling that isn't in use or can be covered up with plastic sheeting to trap dust and prevent it from damaging the primed surfaces below.

Step 2: Clean the Surface

It's critical to clean the surface before painting. Cleaning will remove all dirt, grease, contaminants, and grime so the primer will adhere to the painted surfaces properly.

Soak the sticky surface in soapy water for at least 30 minutes. If your painting process requires deep cleaning, use a high-quality degreasing pre-paint cleanser instead.

For faster cleaning, you may use a pressure washer on large pieces of furniture or the outside of your property. Allow the surface to dry completely before proceeding.

Step 3: Remove Any Old Gloss Paint

You'll need to remove the old oil based paint coat on the surface. Make sure you use a wire brush attachment for your electric drill to remove any loose paint particles, dust, dirt, and grime.

Don't forget to wear protective gear so you don't inhale dust or get exposed to hazardous chemicals.

Step 4: Sand the Top Layer

Once you have removed all loose paint particles using a putty knife, it's time to sand the top latex paint layer using sandpaper to remove brush marks. Use the sandpaper by rubbing it in circular motions over the entire surface.

You don't need to apply much pressure, just enough for the sandpaper to get into the grooves of the wood. Make sure you also test the surface to assess how it's doing.

If you notice that there are still some glossy spots stuck in the wood, continue until they are all removed. Wash away any dust left on the surface using a damp tack cloth, and give it time to dry.

Once dry, sand the surface again with sandpaper or use a finer grit—this will make the coat easier to paint over.

Step 5: Apply Primer

After that, apply the primer in the same manner as indicated on the bottle. The primer layer allows the latex to stick to the oil.

It's best to use primer in the color of your choice and apply two coats in quick succession—apply a thin coat and leave it to dry before applying the second coat.

Step 6: Sand Again

You'll need to sand over the prime to make it even with the surface of the wood. Use 100-grit sandpaper to get rid of any lumps, bumps, and uneven wood surfaces. This will help the latex bond well with the primer.

Step 7: Paint

After that, apply a single coat of high quality latex paint using your roller, brush, or airless sprayer of your favorite latex topcoat. Make sure you don't skimp on the number of coats—the more layers, the better!

You may need to apply anywhere between three to five thin coats to achieve full density.

Step 8: Seal

Finally, to make your paint job last even longer, seal porous surfaces with a quality clear coat. Use a brush or roller and apply the sealer over the latex once it has completely dried. Again, don't skimp on coats—the more layers you apply, the longer your painting projects will last!

Step 9: Dry Time

You cannot apply another layer of latex paint for four hours, even if the first coat dries to the touch in an hour. Allow at least 48 hours of dry time before handling or your completed work.

You might reduce the dry time by using light layers of oil paint. Thinner paint dries faster. Using a hairdryer, fan, or space heater can also speed up the process.

Tip On Placing Latex Over Oil Primer

It is important to note that oil-based primers can take up to eight hours to dry. This is why you may want to sand the primer slightly to provide a better bonding primer surface.

It's also critical to wash any dust particles that may have been caused by the sanding process, allowing it to dry before you paint the surface.

As a general rule of thumb, it's best to apply two latex paint layers over your primer and allow between two to four hours for each of the oil primer latex paint to dry.
