Questions & answers

Which primer blocks stains best?

For heavy stains like water, smoke and tannin bleed, contractors usually reach for an oil-based primer such as KILZ Original or a shellac primer such as Zinsser B-I-N. Water-based primers like KILZ 3 Premium and Bulls Eye 1-2-3 clean up with water and suit lighter stains.

Are these sold by the gallon?

Yes. KILZ Original is sold by the gallon in multiples of 4. KILZ 3 Premium and Bulls Eye 1-2-3 come in packs of 4 gallons, and Zinsser B-I-N in packs of 2. The table shows the pack price and the price per gallon.

How fast does it ship?
