Can it be used on damage drywall before applying texture?

Asked by Guero June 4, 2021
1
Answer

Hi Guero. Thanks for writing in with your question. Yes, this primer can be used on the drywall and textured joint compound can be applied over it after the primer's recoat time. I also recommend lightly scuff sanding the primer and wiping off the sanding dust to help promote adhesion before adding the texture. Good luck with your project! -Joni

Hi Leahh, Thank you for writing in. As it turns out, we do not recommend thinning/diluting KILZ Original Primer.

@KILZ The Use and Care Manual posted on the Home Depot product page states, "Seals persistent smoke, pet and food odors," so that's where I'm confused when you say it doesn't seal in odors.

You should use latex primer if you're following with latex paint. Latex paint will not adhere well to oil.

Does this actually kill mold if used to paint over it?

Asked by Bub October 15, 2020
2
Answers

Hi Bub, thank you for your question. Our Interior/Exterior Original Primer provides a mildew resistant finish, meaning that the top of the primer finish has mildicide to help prevent the growth of mildew on the finish. However, the surface you are coating must still have all active mildew/mold spores cleaned before coating. We hope this information helps. Best of luck with your project. -Joanna

Kilz Primer ruined my brand new wood door
My brand new wood door called for an oil based primer before the final coat, so I decided to use this product from Kilz. I started applying it and noticed it wasn't going on as smoothly as I expected. I thought maybe I had too little product on the brush so went a little heavier on my next coats. Within 3 minutes when I went to go over it once more to even out the brush marks, it was sticking horribly to the brush and making paint clumps all of the door. I had plenty of paint on my bristles, so it wasn't that the brush was dry. I spent the next 3 hours carefully scraping as much of it off as I could. An electric sander did nothing to help, so all I could do was use a putty knife and go at it slowly to try to not damage the wood. I ended up with a few gouge marks in spite of being careful and never was able to remove all the residual paint. I followed the directions completely, since I wasn't familiar with oil based primer. The temperature was 65 degrees, the can was shaken by hand for several minutes and then stirred after I opened it for another 2 minutes, so it was well mixed. The primer seemed very think. Maybe a bad batch? Expired product? Who knows, but what I do know is that I'll never trust a Kilz product again. Horrible experience.

Response from KILZProblemSolverJan 15, 2021
Hi KevinB - Thank you for your review. I'm so sorry to hear about the trouble you ran into with our primer on your new door! To help prevent brush marks and clumps, it's best to avoid going over the same areas multiple times as this can begin to remove the product from the surface. If the fresh coat leaves an unwanted texture on the surface, we recommend allowing the primer to dry for 24 hours before gently sanding down the texture with 180-240 grit sandpaper. Once the sanding dust has been wiped off, you can apply another coat for a smooth finish. This primer should also have a creamy consistency, however, if it seems too thick, you may want to continue your project with a new can. We'd be happy to assist you with this further. Please feel free to reach out to us directly at your convenience. We hope to hear from you! - Sara Kilz

Kilz original oil-based interior/exterior primer is a wonderfully effective product. It is great for priming drywall, sealing/covering tough stains, and can go over a variety of surfaces. I've used it on a number of surfaces (drywall, wood, plywood, OSB, masonry surfaces) both interior/exterior and it is truly one of the best primers out there and is easy to apply. Just remember -- it is oil-based so clean up is a bit tougher than latex (water-based) primers. Because it is oil-based, it won't cause materials such as OSB or plywood to swell with increased water content. Furthermore, because it is solvent-based, the dry time is VERY fast. Just make sure to stir it up very well before using it as it can settle fairly quickly. We used it in this case to prime a vertical exterior masonry wall (old concrete parging over brick) that had been painted multiple times over its many years. Pressure Washed/Cleaned, Scraped, Repaired, Sealed, Primed, and Painted! Lots of steps. The column base was removed/replaced after copying the original which couldn't be repaired/salvaged. In the picture, it is primed but hot caulked or painted yet. Another big/complicated project.
