FAQs

What kind of stains can Zinsser B-I-N block?

Zinsser B-I-N is highly effective at blocking water stains, mildew, nicotine, oil stains, marker pen, and stains from fungal degradation.

Can I use this primer on glossy surfaces without sanding?

Yes, Zinsser B-I-N is formulated for incredible adhesion to glossy surfaces, including glass, often eliminating the need for scuff sanding. Always ensure the surface is clean and dry.

How quickly does Zinsser B-I-N dry?

It is touch-dry in just 15 minutes and can be recoated or topcoated in as little as 45 minutes, allowing for very quick project completion.

What should I use to clean my tools after using this primer?

Since Zinsser B-I-N is a shellac-based primer, you should clean brushes and equipment immediately after use with denatured alcohol or methylated spirits. Water will not be effective for cleanup.

Is this primer suitable for exterior use?

It is primarily recommended for interior surfaces like ceilings, walls, and doors. However, it is also suitable for spot priming exterior surfaces such as metal, trims, PVC, and wood.

Does it really block strong odors like smoke?

Yes, Zinsser B-I-N is very effective at permanently blocking all kinds of unpleasant odors, including those from smoke, fire damage, pets, and nicotine, sealing them away from the topcoat.

What is the coverage rate for a 2.5L tin?

A 2.5L tin of Zinsser B-I-N provides coverage of up to 31.25 square meters, based on an approximate coverage rate of 12.5 square meters per litre.

Troubleshooting

Stains or odors are still visible after priming

Ensure the primer was applied as a thin, even coat. For severe stains or odors, a second coat of B-I-N primer may be necessary. Allow proper drying time between coats before reapplying or topcoating.

Poor adhesion of topcoat

While B-I-N offers superior adhesion, ensure the surface was clean, dry, and free of contaminants (dust, grease, wax) before applying the primer. Also, confirm that the topcoat is compatible with shellac-based primers and was applied within the recommended recoat window.

Primer is not drying properly

Check ambient conditions. High humidity or low temperatures can extend drying times. Ensure good ventilation to allow solvents to evaporate. If applied too thickly, it can also slow down drying. Apply thinner coats.

Strong odor persists after drying

While the odor is strong during application, it should dissipate as the primer dries and cures. Ensure the area is well-ventilated for several hours after application. If odors persist, ensure all surfaces are thoroughly primed, as some odor sources might not have been fully encapsulated.

Pros and Cons

Pros

  • Exceptional adhesion to glossy surfaces without sanding
  • Permanently blocks a wide range of tough stains
  • Effectively seals and eliminates unpleasant odors
  • Very fast drying and recoat times for quick project turnover
  • Suitable for both interior and exterior spot priming applications

Cons

  • Strong odor during application, requiring good ventilation
  • Clean-up requires denatured alcohol, not soap and water
  • May require multiple coats for very severe stains or odors
  • Not ideal for large exterior areas due to shellac properties and solvent base

Setup, Compatibility & Care

Surface Preparation

Ensure surfaces are clean, dry, and free from loose paint, dust, dirt, grease, or wax. While Zinsser B-I-N offers incredible adhesion without scuff sanding, a clean surface is always essential for optimal performance. Remove any peeling or flaking paint.

Application

Stir the primer thoroughly before use. Apply with a good quality brush, roller, or sprayer. For best results and maximum stain/odor blocking, apply a thin, even coat. Allow 15 minutes for the primer to be touch-dry and 45 minutes before applying a second coat or topcoat. Always ensure adequate ventilation during application, as the product has a strong odor.

Compatibility

  • Interior Surfaces: Excellent for ceilings, walls, and doors.
  • Exterior Surfaces: Suitable for spot priming metal, trims, PVC, and wood.
  • Topcoats: Compatible with most topcoats, including water-based and oil-based paints.

Coverage

One 2.5L tin covers approximately 31.25m², based on a coverage rate of 12.5m² per litre.

Cleanup & Storage

Clean brushes and equipment immediately after use with denatured alcohol or methylated spirits. Do not use water. Store the tin tightly sealed in a cool, dry place, away from direct sunlight and extreme temperatures.
