Product Information

Always follow manufacturer recommendations and best practices to ensure the longevity and quality of your finished work. Troubleshooting

Rust converter from 3M also acts as a primer after changing the rust by chemical reaction. I would still recommend that you prime with Rust Scat (just above) after using it as well before painting. Regular Updates: Our recommendations stay current with any changes in product performance or availability.Oh, I won’t prime the entire piece if I’m working on a project that has already been painted and I’m only repairing a knot that has bled through the paint. The three coats of Zinsser BIN Primer we applied to the knot will be a great base for our paint. 5. Paint the Project Self-priming paints—also known as paint-and-primer combo products—let users prime and paint a surface in a single step. But these two-in-one products are only recommended if all of the following are true:

Issue: The primer or paint layers were not allowed to dry thoroughly before applying additional coats, leading to poor adhesion and potential knot bleeding. Solution: Allow each layer of primer and paint to dry according to the manufacturer's recommended drying times. This ensures proper adhesion and helps prevent issues with knot bleeding. The knots might not come through, but would still be seen as round imperfections, but not the difference in color: that would all be made the same by the primer. Have you ever painted over a wood knot only to find a little while later the knot is bleeding through the paint? It’s happened to all of us, but there’s a foolproof way to stop knots from bleeding through our paint. Choose a high-quality paint suitable for your project, such as an acrylic latex paint for indoor applications.Paint with primer is best for previously painted walls. Primers are recommended for use on any surface that has not been previously painted. Q. Do I have to use paint primer?

Tip on primers used for spot priming. BIN, in particular, is nasty stuff and as soon as you put a brush in it, that brush will never be useable for anything else. I buy dollar-store brushes for this, even though the bristles fall out! Here is what I do: before dipping the brush, cut off the handle so the brush will fit inside the can with the lid closed. After you’re done priming, seal the brush in the can! Yes, it’s messy when you go to get it out (rubber gloves, man), but you only ruin one brush per can. Paint and Primer in One? Water-based primer is best for walls and ceilings. Oil-based primer is primarily used for doors, windows, metal, woodwork, or over tough stains in well-ventilated areas. Q. Which is better: primer or paint with primer? Sometimes you’ll see a pink color bleeding through your primer. You may wonder where the pink is coming from. This is wood tannins coming through and it almost always requires a shellac-based primer.

When it’s time to spruce something up in your home with a fresh coat of paint, the temptation is always going to be there to jump right in and splash that bold colour on the walls, ceiling, skirting boards. But, hold your horses, because to make sure your colours are going to stand out and sit properly on the surface you’re painting you often need to consider the undercoat paint. Spraying primer? Sure. Go for it. We have written all about sprayers here. Graco is the brand that most professional painters trust. Bob Vila has been America’s Handyman since 1979. As the host of beloved and groundbreaking TV series including “This Old House” and “Bob Vila’s Home Again,” he popularized and became synonymous with “do-it-yourself” home improvement. The primer is low odor, low in volatile organic compounds (VOCs), and provides excellent coverage on interior and exterior surfaces. It’s made from water-based acrylic and is designed to resist blistering, peeling, and mold and mildew growth. The primer is tintable and available in white or gray. It’s also available in spray-paint form. Once the primer is dry I apply a second coat. And then a third coat. I usually only have to apply three coats, but I will apply additional coats if I can still see the knot. In other words, we need to keep applying coats of primer until we can no longer see the knot.While there may be no issues currently, bleed-through could still occur over time if a primer was not used initially.
