Can I paint water based paint over oil based paint?
Considering this, how do you paint over oil based paint?
To apply latex paint over oil-based:
- Lightly sand the surface with fine sandpaper (180 to 220 grit) to remove the gloss.
- Clean the surface with a sponge dipped in a solution of TSP (trisodium phosphate) mixed with water.
- Remove the cleaner with a sponge and clean water, then allow the surface to dry.
Subsequently, question is, what happens if you paint latex over oil? Why Oil Paints Don't Mix Furthermore, if you were to use an oil paint over latex, the new paint will expand and contract at a different rate than the underlying layer, causing it to crack. Latex will not properly stick when applied directly on top of an oil-based layer without preparation, and may easily crack or peel.
In this manner, what paint can I use over oil based paint?
Latex or oil-based paint can be successfully applied over oil-based paint. As long as the surface is fully cured, there is nothing inherent in the oil-based paint coating that precludes an additional layer of latex or oil-based paint.
How do you tell if old paint is oil based or water based?
Rinse well and towel dry. Then soak a cotton ball, Q-tip or soft rag in alcohol and rub it back and forth over the cleaned area. If paint comes off, it's latex and another coat of the same is in order. If the paint doesn't come off, it's oil-based, and an oil-based primer is a must.
