When painting over painting walls, you have to be careful of one thing: the type of paint you’re using. Oil and latex paint don’t mix. Most interior paints are latex based, so 99% of the time there is no problem.

However, oil based paints are great to use in high humidity situations like your kitchen and bathroom. If you have your doubts, you should test the paint on your walls to determine if it’s oil paint or latex paint before updating your wall color.

Can I Paint Over Painted Walls: How to Test For Oil Based Paints

You can check your paint type by saturating a shop rag with non-acetone nail polish remover. Take the soaked rag and run it over the painted surface in question. If no paint comes off on the rag, then you know for certain that it is an oil-based paint.

If the surface is coated with latex paint, then you’ll have some paint come off on the rag or the surface will feel sticky afterward.

What Happens if I Paint over Oil Based paint with Latex Paint?

Using latex paint, which is water based, when painting over oil-based paint could cause chips and peeling. This is because oil based paints are glossier. Remember oil and water don’t mix when you’re cooking and they don’t mix when painting either.

If you want to paint water based latex paints (or any water based paints) over oil paint, you would need to use a good quality bonding primer over the oil paint first. This way the latex paint has a surface that it can easily bond to. This is an extra step that will create professional results.

Condition of the Existing Paint

Before you paint over existing paint, you need to make sure that it is in good condition. If the paint is peeling, cracking, or flaking, it’s best to remove it, sand it, and use a good primer. Painting over damaged paint will result in an uneven finish and may not last as long as it should. This can cause peeling, cracking, and moisture and dirt to get under the new coat of paint.

Color of the Walls

If you’re changing the color of your walls, you may need to apply multiple coats of paint to get good coverage. In some cases, you may need to use a primer before applying the new paint to ensure good coverage and a uniform finish. Greens and blues are notorious for being hard to cover; you will definitely need to use a primer over such colors to prevent them from bleeding through.

Before painting over painted walls, it’s essential to clean them thoroughly. Dust, dirt, and grease can affect the adhesion of the new paint and result in an uneven finish. Use a mild detergent and warm water to clean the walls and let them dry completely before painting.

Sand the walls

Lightly sanding the walls before painting can help the new paint adhere better and result in a smoother finish. Use a fine-grit sandpaper to sand the walls lightly and remove any rough spots or imperfections.

Fill any holes or cracks

If there are any holes or cracks in the walls, fill them with spackle or putty and let them dry completely before painting. This will help ensure a smooth finish and prevent the new paint from cracking or peeling.

Using a primer can help the new paint adhere better to the existing paint and ensure good coverage. If you’re changing the color of your walls or if the existing paint is in poor condition, it’s recommended to use a primer before painting.
