Zinsser rolls out tannin blocking primer with superior adhesion

New primer offers fast dry times – low temp application

Rust-Oleum is expanding on Zinsser’s trusted line of specialty primers with the addition of Zinsser Exterior Wood Primer.

This water-based primer is great for new and previously painted wood trim, siding, fencing and more. It excels at blocking tannin stains from cedar, redwood and other bleeding woods. This primer provides superior adhesion while still remaining flexible and can be applied in low temperatures.

“When it comes to exterior wood, priming is essential,” said Melanie Delcore, primers and specialty coatings brand manager at Rust-Oleum. “New wood and previously painted wood are tough surfaces to paint. Our powerful wood primer excels at blocking tannin bleed while providing great adhesion.”

Fast dry times help with quicker project completion. With Zinsser Exterior Wood Primer, professional painters and do-it-yourselfers can topcoat within one hour.
