Shellac-Based Primers
</h2>
Zinsser BIN is the gold standard for blocking severe stains, including smoke damage, water rings, and pet odors. It dries in under an hour and seals knot bleed in pine. The trade-off is a strong odor, so ventilation is essential during application.
<h2>
Oil-Based Primers
</h2>
KILZ Original and Zinsser Cover Stain handle moderate stains and adhere well to glossy surfaces. Oil primers excel at sealing nicotine, water damage, and grease. They take longer to dry than shellac but produce less harsh fumes.
<h2>
Water-Based Stain Blockers
</h2>
For lighter stains and projects in occupied homes, Zinsser Bulls Eye 1-2-3 Plus and KILZ 2 Latex offer good performance with low odor. They are the right choice for nurseries, bedrooms, or any space where strong fumes are not acceptable.
