Can You Paint Latex Paint Over Oil-Based Primer?

Yes, you can paint latex paint over oil-based primer & it’s one of the most advised practices from woodworkers. It’s worth mentioning that – Oil-based paint suits oil primers best, but the longer drying period is an irritating issue for some. However, you can go away with latex paint as it works on oil-based primers as well. The plus point of latex paint is the lesser drying time compared to oil paint. 

Should You Paint Latex Paint Over Oil-Based Primer?

If you’re in a hurry & want the best paint type for your oil-based primer – go with latex paint. Latex paint will allow you to completely paint a room in less than 16 hours which is impossible with oil-based paint. Besides the drying time, latex paint is also comparatively cost-effective. You won’t feel miserable spending your cash on latex paint & it’s guaranteed from me. 

There are three types of latex paint available in the market, such as:

  • 100% Acrylic Latex
  • Vinyl Acrylic Latex
  • Alkyd-Modified Latex

Make sure you’ve purchased the 100% Acrylic Latex as it performs the best with an oil-based primer. The other types are also okay, but they are not that convenient with oil-based primers. With that said, choose your latex paint wisely & follow the next segment, which is a step-by-step latex painting guide.

How To Paint Latex Paint Over Oil-Based Oil-Based Primer?

In this segment, I’ll be sharing my step-by-step guide on painting latex paint over oil-based primer. Before following this guide, make sure you’ve got these pieces of equipment/materials: 

  • Wood Cleaner
  • Tack Cloth
  • 180-Grit Sandpaper
  • Latex Paint (100% Acrylic Latex)
  • Paint Brush/Roller 

Considering you’ve already primed the surface with oil-based product, I’ll be starting this guide. Without further ado, let’s get started:

Step 1: Clean The Surface

Preparing the surface is the most crucial task of any painting job. To avoid future regret, make sure you’ve prepared the surface properly. Mainly you’ve to clean the surface thoroughly. Here’s the quick checklist for cleaning the surface area:

  • Remove Any Old Gloss Paint
  • Remove Dust & Debris
  • Finally, Clean The Surface With Tack Cloth 

By clearing these tasks, you’ll be preparing an absolutely wonderful surface for further painting works. 

Step 2: Sand The Surface

After cleaning the surface, you’ll have to sand it thoroughly. I’d recommend using 180-grit sandpaper & having patience while performing the sanding job. Please keep in mind that – the main purpose of sanding is to make the surface rough enough for the oil paint to adhere. Don’t go too hard while doing this task, as you might ruin the primer coatings.  

After sanding, make sure to clean the surface again with liquid cleaner & tack cloth. It’s because sanding will cause lots of wood residue that may harm the painting process. 

Step 3: Apply First Coat Of Latex

Now it’s time for painting. Take your 100% Acrylic Latex Paint along with a painting brush or roller. You might be wondering, what’s the best time for using a roller or brush? I’ve given an easy equation below to help you with your decision making:

  • Roller Usage: Use a roller on wider surfaces. Mainly these surfaces are easily accessible & the roller makes the painting process faster than a brush. 
  • Brush Usage: Use a brush on hard-to-reach areas of your cabinets, floors, or furniture. It will take time, but at least you’ll be able to paint with a brush.

At last, apply the fresh coat of your latex paint & wait for two to four hours. You might have to wait longer depending on your weather condition. 

Step 5: Apply Second Coat Of Latex

After the waiting period, apply the second coat of latex paint. You may think of sanding the surface again – just don’t. There’s no need to sand the surface after the first coat of paint. If you can’t help but sand the surface, use liquid sandpaper for sanding the surface mildly.
