Professional painters know that priming is the key to great paint results and Zinsser primer-sealers are specially formulated to perform five important functions common paints and primers will not, guaranteeing professional results every time. Zinsser primers:

1. Seal porous surfaces
   Common primers soak into porous surfaces, resulting in a weak and uneven appearance which multiple coats of finish paint may not correct. Zinsser primers are formulated to fill open pores creating a smooth, even and uniform base, ensuring true enamel holdout and single coat application of the finish paint.
   
2. Kills all stains
   Zinsser primers are formulated with premium, stain blocking pigments, high performance resins and quick drying performance, ending the worry of unsightly bleed-through of stains into the finish paint. Graffiti, marking inks, nicotine, water stains, etc. are permanently sealed beneath the primer film and the job will finish blemish free.
   
3. Hide unwanted colors
   Multiple coats of paint are normally required to hide unwanted colors. Zinsser primers contain large amounts of premium, high-hiding white pigment to conceal these unwanted colors and surfaces in one coat and provide a bright, white base for your finish paint. You can even tint any Zinsser primer to your topcoat color, ensuring one coat coverage.
   
4. Enhance adhesion
   Hard, slick or glossy surfaces are no problem for the high-adhesion qualities of all Zinsser primers. Specially formulated resins firmly anchor the primer film to these challenging surfaces without sanding or de-glossing. Zinsser primers deliver excellent bond coat performance where typical paints might chip and peel.
   
5. Extend topcoat durability
   Zinsser primers seal surfaces so effectively that more high-quality resin remains on the surface. Topcoats are more durable, chip resistant, wear longer and have better scrubbability when applied over Zinsser primers.
   
   Zinsser primer-sealers save you time and money and help you paint like a pro.
