Start With Sanding the Surface

This is the mandatory step that must never be skipped! As we have previously mentioned, latex paint is rather flexible in nature.

As a result, when applying the two distinct paints one over another, chances are high that oil-based paint will not be able to properly adhere to latex.

Well, unless you sand the surface and add primer between each of the layers.

This is why you should start by equipping yourself with a piece of P80 grit sandpaper. With its help, do your best to remove as much of the latex from the surface as possible.

You can also use a sanding block if this method is more preferable for you. By removing the latex from the surface, you will help the oil-based paint to adhere much better than if the latex was left on.

Make sure you sand the surface down until you get a real matte look.

Now a Bit More Sanding

If you think that you are done with sanding, we are here to tell you that it’s not the end yet!

You will now want to make use of 150 grit sandpaper instead of the 80 grit one, and sand your surface until you get it extremely smooth.

After the surface has been completely sanded, wipe away the dust left behind with a damp towel or a clean cloth and let the surface to completely dry.

Time to Apply the Primer

After you sanded the surface and after the masking tape is applied, it’s time to proceed and apply the primer. At this point, you can choose between a water-based primer or an acrylic primer.

Each of these primers work well, but also, each has its particular pros and cons. Both water-based and acrylic primers create the perfect isolating surface.

After you have applied the primer, and it is fully dried, the next step is to go ahead and apply a second coat.

It is important to make sure that you cover every single piece of latex possible!

• Oil paint is easier to wash off when making a mistake.
• Unlike latex, oil paints are stronger in terms of confronting washing cleansers.
• all flaws are easier to hide with oil paints since they are much thicker.
• The surface provided by oil-based paints is smoother to the touch.
• Oil-paint is better since it is more visually pleasing, smoother, and firmer.

Finally, there is another great advantage. See, oil-based paint offers a less clear refractive file unlike latex paint. This happens because the linseed oil contains smaller particles than latex paint does. This is why the coat of oil paint gives a more profund and warm feeling than latex paint.

Even though it may require extra work, using and applying oil-based paint is possible in almost any situation. Here you can check out the projects which this paint can be very fitting for:

• doors
• cabinets
• full-gloss finish surfaces
• trims
• rooms with high levels of moisture, like the bathroom

When using a faux finish, you can easily manipulate and play with it however you may like, due to the extended drying period of oil-based paints.
