KILZ® ORIGINAL Interior | Exterior Primer is rated 4.7 out of 5 by 50.
Rated 5 out of 5 by from Great Coverage I used this product on a wall that had candle dippingssplatterings. I removed as much of the wax as possible, but there were still obvious spots on the wall. After using this Kilz product my wall looks great & you would never know that it once had candle wax on it. This product is also great for covering up old leak stains as well. I would highly recommend Kilz to anyone.

Rated 5 out of 5 by from Awesome product I needed paint for a railing on a house built in the 1950's. The paint always chips off, rusts and spray paint would bleed through in about 6 months. I used the black primer and it felt like satin. I am very pleased with the results.

Rated 5 out of 5 by from For Teenager complaint Redoing a child's room now that the had become a teenager (following a complaint that a Winnie the Pooh mural was no longer appropriate, I found that Kilz Original Interior exterior primer covered the mural nicely leaving a surface ready for the "more mature" bulue my son had chosen.

Rated 5 out of 5 by from Great product I bought this to paint some furniture for my kitchen and my wooden swing in my yard. I love how I can use the same product for both projects without buying multiple primers. It always does a great job, your paint always goes on so smoothly.

Rated 3 out of 5 by from changed formula I used this product before and it did cover stains. Something has happened to the formula as it is now not covering the stains as it once did. Not sure why is is now not working as well as it did two years ago.

Rated 4 out of 5 by from Good coverage We have a 1910 house and the windows were painted dark brown. We are scraping and painting them white. Kilz original does a good job of the transformation and should last for another 25 years.

Rated 5 out of 5 by from Great White Color stays on. I repurposed old fencing into a 12 ft. yard gate to store a camper and boat in my backyard. The fencing was old and didnt think it would last years but good enough for now. Boy was I wrong. Here it is 3 years later and my gate stayed White. So happy with Kilz!

Rated 4 out of 5 by from Covered up cat urine from previous owners The house we just bought smelled so strongly of cat urine that we could barely breathe & were getting headaches. Used Kilz in the worst room & it covered it up well. The Kilz was noxious (use a heavy duty mask) even in a we'll ventilated room, but once it dried the smell was undetectable.

Rated 5 out of 5 by from Great Coverage I used this 2 weeks ago on the interior of a 100 year cupboard in my laundry room. The interior had never been painted. This brighten the interior of the cupboards, I applied 2 coats of Kilz and one coat of paint.

Rated 5 out of 5 by from Makes painting easier, faster, and more uniform. I bought a ppg paint with primer that’s supposed to be guaranteed single coat. I was painting a concrete fence from dark green to white. In the end, I still had to do 2 coats. Then in the other side of the fence, I tried with kilz primer and a behr paint. This resulted in a more uniform paint that covered the dark green better. And somehow, it also made it easier and faster to paint after a primer.

Rated 5 out of 5 by from Covers wood cabinets beautifully I bought the 5 gallon kilz original oil based primer a few weeks ago to prime and update sad looking cabinets. This primer works wonders making the wood smooth and a great surface area to paint with an oil based top coat. I am very happy to have gotten this primer. Very high quality that shows in your work, also the primer had really very little odor, if you want a job to go smoothly and done right use kilz products!

Surface Preparation

The following steps are recommended for product performance.

  • All surfaces must be clean, free of dust, chalk, oil, mold and mildew, loose peeling paint, rust and all other foreign substances.
  • If washing is necessary, use a non-soapy detergent or a TSP substitute, rinse well and allow to dry.
  • †Glossy Surfaces: For maximum adhesion, scuff sand the surface thoroughly before priming.
  • Peeling or Checked Paint: Scrape off loose paint and sand to a smooth surface.
  • Mold or Mildew Covered Surfaces: Wash the area with a mildew remover, rinse with water and allow to dry before priming.
  • Masonry, Brick, Stucco and Plaster: KILZ ORIGINAL INTERIOR/EXTERIOR Primer may be used on clean, dry, aged masonry surfaces that have cured (dried) at least 90 days. If masonry has cured less than 90 days, use KILZ PREMIUM or KILZ 2® Primers.
  • Fire Restoration: It is critical to clean smoke damaged surfaces thoroughly before priming.

Application

  • Eye protection is recommended. Do not thin. Stir thoroughly before and occasionally during use.
  • Apply using a brush, roller or sprayer.

  • Airless spray – .015-.021 tip / 60 mesh filter
  • Prime entire surface to ensure a uniform appearance of the topcoat.
  • Stainblocking: After priming, test for stain bleed-through by applying the topcoat to a small section. If the stain bleeds through the topcoat, apply a second coat of primer and test again before topcoating the entire area. If bleeding continues, a longer dry time is needed before topcoating.
  • Tinting: Up to 2 ounces of universal colorant per gallon. Tinting to a lighter shade than topcoat is recommended.
