Rated 5 out of 5 by from Covered cat odor! Before our son was born we needed to convert what had been a home office to a nursery. We discovered our cat, who had urinary issues, had marked many places through to the floorboards under the carpet. We removed the carpet and painted on Kilz. Problem solved before new carpet was installed.

Rated 5 out of 5 by from Wonderful product I had a bright idea over 15 years ago to paint my kitchen with white paint and then while it was still ‘sticky’ to go over that using a whisk broom using blue paint in different directions. I finally convinced my husband to paint over it- KILZ done the job beautifully!!!! It not only covered up the blue but we only had to give one coat of the almond color I chose.

I spent the night there on the day I closed on the house and suffered a massive headache due to the odors trapped in the floor, namely dog urine everywhere. We applied Kilz to all the floor (I was replacing floor anyhow) and the smell went away.

Rated 5 out of 5 by from Fantastic cover-up I have recently began attempting to freshen up my home a bit. I had been caregiver of an elderly relative and he left it to me after his death. It has not had anything done to it in 20 years. I needed the Kilz to cover-up years of cigarette smoke, smoke from a wood stove, and worst of all kerosene oil smoke. I didn't think anything would work but amazingly Kilz original has done a fantastic job. I look forward to seeing the finished product in another week or so.

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.
  • 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 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, KILZ 2® or KILZ ORIGINAL LOW ODOR® 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.

  • Airless spray – .015-.019 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.
