KILZ 2® GRAY<br/> Interior | Exterior Primer

Interior | Exterior Primer






KILZ 2® GRAY Primer is a fast drying, water-based, multi-surface primer-sealer-stainblocker which is best used under dark, rich and deep vibrant color topcoats. This helps achieve more accurate color with fewer coats of paint and also improves hiding of previous colors. KILZ 2 GRAY Primer has excellent adhesion, sealing properties and a very mild odor. Effectively blocks “light to medium” stains including water stains, rust, grease, ink, pencil and felt marker. Use on interior and exterior surfaces including woodwork, drywall, plaster, paneling, masonry, brick, painted metal and properly prepared glossy surfaces. Use under or over water-based or oil-based paints. Not recommended on flooring.

Rated 5 out of 5 by from Love the Grey Tone I bought Kilz 2 Gray Interior/Exterior to prime an outdoor fence that was going to be painted white. Used the Kilz 2, and when we had to paint the final finish of white on the fence, the gray tone made it so easy to see where we needed to paint. Also this covered all the knotholes and imperfections in the wood fence.

Rated 5 out of 5 by from Wow! We had an old Rusty trailer to paint. I was not very optimistic about the outcome. After some pretty diligent prep work we put a coat of Kilz 2 Grey primer on the house. The house was in such bad shape that I decided to put a second coat of primer on it and let me tell you, the paint went on beautifully! I have always been a fan of the Kilz primers but this time, they knocked my socks off!

Rated 5 out of 5 by from One coat made the yellow disappear! We are covering a section of yellow wall with rough barnwood that would have gaps in it exposing the color of the wall behind it. The gray primer was the perfect color match for the barnwood so we used it to cover the existing bright yellow. One coat worked perfect. Even if we weren't going to cover it with wood it was good enough to leave exposed. One coat, job done!

Rated 5 out of 5 by from Barndominuim Excellent product , I needed to primer new drywall and textured walls for barndominium. My wife decided an a gray paint. I researched primer and decided I would use Kilz 2 Gray. I decided to rent a sprayer from a big box store . The kilz covered and sprayed just fine with no problems . Only issue is I'm sore from spaying primer and 2 coats of paint in 13 hours !

Rated 5 out of 5 by from This is one of the most amazing products EVER!! I must say that Kilz brand in general, (Specifically: Kilz 2Latex Gray) is an awesome. Went on great, only had to use one coat, and the finish was awesome. I can’t say that I would recommend; mainly because I already have recommended to clients, friends, family, and Co-Workers. I wouldn’t recommend any other. Kudos, to the makers of/at Kilz; best type: paint, primer, sealer ever invented. Way to go!

Rated 5 out of 5 by from Fantastic! I recently moved into my grandparents house that was built in the 1960's. Hardwoods throughout, & miles & miles of wood paneling! Bless his heart, my grandpa did things the right way, & put panelling over sheetrock. Needless to say, most of my spendable income goes to paint & kilz primer is amazing! I primed 2 bedrooms with 2 galons.

Rated 5 out of 5 by from In Love I do a lot of furniture flipping. This gray is beautiful! I don’t care for the sanding part of flipping! (Lol) This paint goes on smooth, adheres well, even with only a light sanding, it’s great primer layer or base layer. My entire bedroom furniture is this gray, with white, darker gray and silver dry brushed over this then sealed with a few coats of spray poly! Everyone who sees it loves it, and asks me to copy it into their furniture!

Rated 5 out of 5 by from Great stuff to hide previous painted colors I used this because of a recommendation by the store clerk. I was painting one wall in my house a deep red. He said if I don't lay down a good primer it will show through pink and would require a lot of coats of paint. I bought Killz but before applying it I tested the red on the wall and sure enough the clerk was right 3 coats of red and it still locked pink. Went back and applied the Killz and 1 coat of red and the wall looked great.

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.
  • Unpainted, exterior wood exposed to sun and/or moisture longer than 2-4 weeks must be cleaned and sanded before priming.
  • 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 2 GRAY 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 2 GRAY Primer.
  • Fire Restoration: It is critical to clean damaged surfaces thoroughly before priming. Primer recommendations: Water-based primers such as KILZ® RESTORATION or oil-based primers such as KILZ® ORIGINAL (interior use) or KILZ® ORIGINAL EXTERIOR.
