Zinsser 3959 Flat White Spray Primer 15 Fl Oz Aerosol

Product Description

The ZINSSER 3959 is a flat white aerosol spray primer designed for interior surface preparation. Packaged in a 15 fl oz aerosol can with a 13 oz net fill, it delivers coverage of 350 to 450 square feet per can. The flat finish is well suited for surfaces that will be topcoated with paint, providing a consistent base layer. Tack-free dry time is 1 hour, with a recoat window at 2 hours, making it practical for single-day paint schedules. Painters, drywall finishers, and general contractors working on interior renovation and new construction projects are the primary users.

This spray primer is intended for indoor applications on walls, ceilings, and other interior surfaces where a flat, white primer coat is required before finish painting. The aerosol delivery format allows for even, brush-free application on smooth and semi-smooth substrates. It is commonly used in residential and light commercial interior repaint and new-build projects where fast turnaround between prime and topcoat is needed.
