What are people saying about Zinsser Bulls Eye 123 Primer? People saying about Zinsser Bulls Eye 1-2-3 primer generally give positive reviews, calling it reliable all-purpose primer for DIY and professional use. Common praise includes excellent adhesion on many surfaces including glossy, PVC, and tile without heavy sanding, low odor compared to oil-based, easy soap and water cleanup, good coverage in one coat for light to medium stains, and fast 1 hour topcoat time. Many mention it sticks well where other primers fail and blocks water and nicotine stains reasonably well for water-based. Negative comments include that it may not fully block severe smoke, fire, pet urine, or dark tannin bleed in one coat, requiring second coat or stronger shellac primer like B-I-N, and that it can raise wood grain on bare wood due to water base, needing light sanding. Some note it is more expensive than budget PVA primers but worth it for versatility. Overall sentiment on retailer sites and DIY forums is that it is go-to versatile primer, especially for difficult surfaces and general priming, with high satisfaction for adhesion and ease of use.
