Correct Primer For Doorframes

Post by Toby_G »

I had architraves replaced around home internal doorways, the original paint on the framing that remained is a slightly 'yellower' white than the new architrave. I need to touch up as we're selling the house. Just wondering what primer to use. I don't know what type of paint is currently on the frames. I bought Zinsser Peel Stop to use around the exposed edges on walls after sanding (the new architrave is narrower than old). I gather I really need a high bonding primer. Was thinking about Zinsser Bin? But they're quite expensive so don't want to go wrong and short on time so no room for error.

Any (qualified/experienced) ideas welcomed.

Thanks.

Correct Primer For Doorframes

Post by premierdecorators »

Here are some tips and recommendations for touching up the paint around your internal doorways:

1. Assess the Current Paint
Since you're unsure what type of paint is currently on the frames, it’s best to determine if it’s latex or oil-based. You can do this by applying a small amount of rubbing alcohol or acetone to a cotton ball and rubbing it on the paint. If it comes off, it's latex; if it doesn’t, it’s likely oil-based.
2. Primer Recommendations
Zinsser B-I-N: This is an excellent choice for a high-bonding primer. It’s a shellac-based primer, which adheres well to glossy surfaces, prevents bleed-through from stains, and works for both latex and oil-based paints. It's a bit more expensive, but it’s worth it for the quality and quick drying time, especially when you’re on a tight schedule.
Zinsser 123: If you want to save a bit and still have a good bonding primer, consider Zinsser 1-2-3. It’s a water-based primer that adheres well to various surfaces, is stain-blocking, and dries quickly. However, if you have oil-based paint, it might not adhere as well as B-I-N.
3. Preparation
Sanding: Ensure that you sand the areas around the original frames to promote adhesion. A light sanding (220-grit) should suffice.
Clean the Surface: After sanding, clean the surfaces to remove dust and debris. Use a damp cloth or sponge and let it dry completely.
4. Painting
Once primed, use a high-quality paint that matches your new architrave. If possible, bring a sample of the old paint to a paint store for color matching.
5. Testing
If you're concerned about the costs, consider doing a small test area with both primers. This can help you assess the adhesion and finish before committing to the whole project.
Conclusion
While Zinsser B-I-N may be pricier, it’s a reliable choice that can save you time and hassle in the long run. If you go with B-I-N, you should have a good bond and finish. If you decide to use Zinsser 1-2-3, just ensure the surface is properly prepared for the best results. Good luck with your project, and I hope your home sells quickly!
