Zinsser Bin Primer Sealer - White

Yes, Zinsser B-I-N is specifically formulated for interior surfaces and for *spot priming* of exterior surfaces. This includes exterior metal, trims, PVC, and wood where specific issues like knots or stubborn stains need sealing.

In most cases, no. B-I-N offers unparalleled adhesion to glossy surfaces, even glass, without the need for scuff sanding. However, surfaces should always be clean, dry, and free of any loose or peeling paint for optimal results.

Zinsser B-I-N is touch dry in approximately 20 minutes and can be recoated in just 45 minutes. It typically reaches hard dry in 1-3 days, depending on environmental conditions like temperature and humidity.

Because B-I-N is shellac-based, tools and spills should be cleaned immediately after use with denatured alcohol or an ammonia-based cleaner. Mineral spirits or paint thinner can also be used. It is important not to use water for cleanup.

Yes, once dried and fully cured, the film of B-I-N is non-toxic and hypo-allergenic. This makes it suitable for areas where incidental contact with food items may occur, such as kitchen cabinets or pantry shelves.

Yes, Zinsser B-I-N is highly compatible and can be successfully top-coated with virtually any type of paint, including both oil-based and water-based (latex or acrylic) paints.

One liter of Zinsser B-I-N provides coverage of approximately 12.5 square meters (or 134 square feet) per coat. Actual coverage may vary depending on surface porosity and the application method used.

Ensure the surface is completely clean and dry before application. While B-I-N adheres well to glossy surfaces, loose or peeling paint must be removed. Allow proper drying time between coats and before applying a topcoat.

This often indicates that a second coat of B-I-N is needed, especially for very severe stains or odors. Ensure the first coat is fully dry (45 minutes minimum) before recoating. For extremely porous surfaces, the primer might be absorbed quickly, potentially requiring more coats.

Ensure adequate ventilation during and after application. High humidity or low temperatures can significantly slow drying times. Apply thin, even coats; thick coats will take considerably longer to dry and may not cure correctly.

Apply thinner, more even coats to minimize texture. For rollers, use a fine-nap roller cover designed for smooth finishes. For brushes, ensure it's a good quality natural or synthetic bristle brush suitable for shellac-based products. Work quickly, as the product dries fast, making it difficult to smooth out heavy areas once set.
