KILZ® 3 PREMIUM Interior | Exterior Primer is rated 4.7 out of 5 by 286.
Rated 5 out of 5 by from Perfect exterior primer! This primer covered perfectly in one coat. We had a metal tool shed that was rather large and it say under a tree getting stained green by the tree combined with rust. We decided to move the shed to a new area in the yard. As we took the shed apart and sanded the rust off, we used 4 gallons of KILZ® 3 PREMIUM Interior | Exterior Primer before repainting, the shed looks like it will last a few more decades.

Rated 5 out of 5 by from Great cover up and adhesion! I use this on every jobsite I’m at that requires painting or sealing or coating and Killz 3 premium interior and exterior never lets me down and my finished job always looks a cut above the people before me. This product has been around longer than I’ve been living and I’ve never seen a bad job done with Killz 3. Only jobs I’ve seen that are not up to par are ones where Killz wasn’t used first. So happy Killz exists! Without it I can only imagine

Rated 5 out of 5 by from Love it! (All 10 gallons and counting!) We bought this a few months ago for our new home, which needed paint in every room (all 2,000+ square feet). Some of the rooms had "ghost studs", some had discoloration from wallpaper glue, and one large room had VERY pink walls. This primer covered it all! I definitely needed a second coat with most of those rooms, but I tend to expect that and was very pleased with the outcome. I also liked this because it was low odor and greenguard certified, and the recoat time meant I didn't have to waste an afternoon waiting around. Photos show the before and after of our biggest room.

Rated 5 out of 5 by from High quality product! I purchased this product to prep my entrance door, which was a dark mahogany color. It allowed the light blue/gray color to go on seamlessly. I have never used primer before, but it really made a huge difference with the final product! I highly recommend using it for your next project!

Rated 5 out of 5 by from Saved an Antique Dresser My wife brings antique furniture back to life. Often the only way to save an old piece is to paint, rather than stain. One dresser in particular had sat in a barn. The critters that called said barn home had left some very unpleasant smells behind that the dresser top had absorbed. It was such a beautiful piece we had to figure a way to bring it back. Kilz to the rescue! After more careful sanding and Kilz primer, the dresser looked gorgeous and had zero odor. LOVE your products!

Rated 5 out of 5 by from Complete Coverage I used this on my front porch railing which was in pretty bad shape. Completely covered all stains and even helped with covering slight imperfections. Made the actual painting a breeze.

Rated 1 out of 5 by from Horrible Product I finally got a chance to paint my garage and used your Kilz 3 primer. First off the product was too thick, but I continued. I thought it would save time if I used a sprayer and that was a huge mistake. The product continually clogged the sprayer with stringy material and does not clean easy at all, even with soapy water per the directions. Now I have sprayer that I cannot clean. In fact I want to return the sprayer as well but I don't know if I'll be able to. I read the directions to thin the product down with water which helped - but after a few moments, the sprayer clogged again. In a project that should have saved me time, it took more time to continually clean the sprayer because of the Kilz 3 primer. A true waste of money.

Rated 5 out of 5 by from Excellent coverage I bought this product to use on my aluminum siding before we choose a color to paint my house. I was very please how easily it covered. It took no time at all to apply and I was very pleased knowing it would protect my house paint for years to come. Prep work is the most important when painting and this product is an excellent undercoat to a finished product.

The project went on all summer as a fill in job on the farm. The primer held up great, And made the finish coat a snap! No issues after 3 yrs! FYI, Kilnz is the only primer I use. Look forward to trying your paint on my porch and deck this summer. Just finished primer today.

Surface Preparation*

The following steps are recommended for product performance.

  • All surfaces must be clean, free of dust, chalk, oil, grease, wax, polish, 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.
  • Peeling or Checked Paint: Scrape off loose paint and sand to a smooth surface. Sanding or removal of paint containing lead is hazardous.*
  • Glossy Surfaces: For maximum adhesion, scuff sand the surface thoroughly before priming.*
  • 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 3® PREMIUM Primer may be used on clean, dry, aged masonry surfaces. New masonry must be allowed to cure (dry) at least 30 days before applying KILZ 3® PREMIUM Primer.
  • Fire Restoration: It is critical to clean damaged surfaces thoroughly before priming. Primer recommendations: KILZ® RESTORATION for water-based (interior); KILZ® ORIGINAL or KILZ® ORIGINAL EXTERIOR for oil-based.


  • Eye protection is recommended. For spray applications, a small amount of water (no more than 1/2 pint per gallon) may be added. Do not thin for stainblocking applications.
  • Only apply if surface, air and product temperatures are between 50°-90°F (10°-32°C). Stir thoroughly before and occasionally during use. Apply using a brush, roller or sprayer.
  • Brush – High quality Nylon/Polyester
  • Roller – High quality 3/8-1/2" nap on smooth surfaces or 1/2-3/4" nap on semi-rough or porous surfaces.
  • Airless spray – .017-.021 tip / 60 mesh filter
  • Prime the 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: KILZ 3® PREMIUM Primer may be tinted with up to 2 ounces of universal colorant per gallon. Tinting to a lighter shade than the topcoat is recommended.
  • Coverage: 300-400 sq. ft. (27.87-37 m2) per gallon depending on application method and surface porosity.

Dry Time at 77°F (25°C), 50% RH

  • Dries to the touch in 30 minutes.

  • Can be recoated or topcoated in one hour with latex or oil-based paint.

  • Application at lower temperatures, in high humidity or in poorly ventilated areas will affect dry time.
