Next, move onto a sander or sanding sponge to lightly take off the top coat of gloss.
Finally, clean the piece again, free from all dust and debris.
Step 4: Prime
Now apply two light coats of oil primer. Wait until the first coat is dry to the touch before adding the second coat.
Once primed, wait 24 hours before moving to the next step.
Step 5: Sand with Fine Grit Paper
After the primer is dry, sand the surface with 100-grit sandpaper, ensuring the primer is smooth and even.
Step 6: Paint
After sanding, wipe away any dust. You’ll now be ready to paint.
Add your latex paint, allowing plenty of dry time between coats. You’ll likely need anywhere from 2-4 layers of latex paint.
Step 7: Seal the Paint
After you’ve finished painting and have waited for the paint to cure, you can add a clear coat. This will help your paint job last longer and stand up to the elements if the piece will be outside.
Apply 2-3 coats of polyurethane or polycrylic, giving plenty of dry time in between coats.
How to Cover Stains with Oil-Based Primer
If you’re dealing with stains on your walls or ceilings that keep bleeding through paint, you can try coating them with an oil-based primer. Oil-based primers are excellent for covering tough stains.
Before you get started, open up some windows to increase ventilation in the room and put on a respirator mask.
Here’s what to do:
Wipe down the area with the stain
Cover the stain with your oil-based primer
Wait 24 hours
Paint over the primer with any type of paint (latex, acrylic latex, acrylic paint, etc.)
Should I Use Oil-Based Primer on Drywall?
You shouldn’t use oil-based primer on drywall. Instead, opt for water or latex primer.
Oil-based primer emits much harsher fumes, which aren’t ideal for indoor use. So while spot-treating tough indoor stains with oil-based primer is fine, don’t use it on large areas of your home like an entire wall or ceiling.
Oil-based primer does a great job at blocking stains and sealing wood. But, if you’re painting drywall, a water-based primer is the way to go.
Water-based primers are meant for indoor use and don’t emit as many VOCs (volatile organic compounds) as oil-based options.
The good news, though, is that no matter where you apply oil-based primer, you can add latex paint over top of it.
