Can You Use Oil Primer over Latex Paint?

Hi Buddy,

Previously, my house was painted with latex paint due to its availability, and popularity. However, after a few years, I realised that oil-based paint is having its own advantages. I hired professionals to repaint my house with oil paint. I directly asked them, “can you use oil primer over latex paint?” The expert from the NoBroker painting services guided me about the same. He said that latex can be painted over with oil-based paint. But you should first spend some time priming the surface. 

Will oil based paint stick to latex:

Yes it will. Despite the fact that oil-based paint will adhere to latex, improper preparation might compromise adhesion, causing cracking, peeling, and other problems.

How to apply oil-based primer over latex paint:

• Use coarse sandpaper to smooth the surface

You should use coarse sandpaper to lightly sand the surface you intend to paint as your initial step. In most circumstances, you want something that is close to 80-grit, allowing you to start scouring the surface and removing some of the latex paint.

Sand the previous latex paint until it gets a matte finish. If any glossy spots are left, the oil-based paint won't apply correctly, so be meticulous.

• Sand once again with finer sandpaper

You will use finer sandpaper to re sand the previously painted surface after it has been thoroughly sanded. Typically, you should use 150-grit, which will enable you to level the surface.

• Readiness for Primer

You must follow a few safety precautions before applying any primer. For instance, you should apply painter's tape on the edges to minimise spillage if you're preparing one wall but want to leave an adjacent wall. Additionally, you might wish to protect your flooring with a drop cloth.

• Use a primer

It's time for a primer after the preparation. By doing this, you get a brand-new surface and a barrier between the two paints.

Your best course of action might be to use a primer with a bonding oil base. Bonding primers are made to stick to difficult-to-cover surfaces, reducing the likelihood of an adhesion problem. Additionally, choosing an oil-based version guarantees that you won't run into any application issues.

• Wait until the primer is fully dry

Make sure your primer is totally dry before adding your paint. In this manner, the topcoat made of oil-based paint will adhere well.

Check the area for coverage as the primer dries. In some circumstances, you might want to use a second layer of primer to make sure you have a clean, level surface, particularly if you notice any underlying paint colour bleeding through. If you decide to add a second coat, just make sure that it completely dries before continuing.

• Using oil-based paint

Apply a coat of oil-based paint when the priming has completely dried. Work systematically to prevent streaks and other visible irregularities while ensuring that the paint coat is even.

Use oil-based paint with just one layer, if possible. In this manner, you can cover every angle in a single pass. To preserve the finish's quality, wait until the first coat has had time to cure before applying a second coat if necessary.

• Take Care to Remove Tape

You should remove any painter's tape you used carefully. When you pull the tape, the top layer of paint should ideally be slightly damp but not wet. In this manner, it can be removed without damaging a freshly painted surface.

If you used multiple coats or the paint is completely dry, you might wish to score the tape's edge with a razor blade before removing it. This minimises peeling or cracking at the paint line by preventing the paint on the wall from pulling when you pick up the tape.

Hence, I would like to conclude here as I feel this answer suffices your query about “can you use oil primer over latex paint?” I hope this helps:)
