High-Performance Shellac-Based Primer

Zinsser B-I-N features a specialist shellac-based formulation designed for demanding priming and sealing applications.

Unlike ordinary general-purpose primers, it combines strong adhesion with exceptional stain and odour blocking.

This makes it particularly useful when preparing surfaces affected by:

• Persistent staining

• Smoke contamination

• Nicotine deposits

• Water marks

• Oil stains

• Timber resin bleed

• Unwanted residual odours

• Difficult glossy finishes

The shellac formula creates a dependable foundation for compatible decorative topcoats.

Powerful Stain-Blocking Primer

One of the main advantages of Zinsser B-I-N is its ability to block stubborn stains that can otherwise bleed through finishing paint.

Applying ordinary emulsion or decorative paint directly over stained surfaces may allow discolouration to reappear.

B-I-N helps isolate the staining beneath the new paint system, creating a cleaner and more uniform finish.

It is particularly useful for blocking:

• Water stains

• Nicotine

• Oil

• Marker pen marks

• Timber knots

• Sap streaks

• Staining associated with fungal degradation

For particularly severe contamination, additional coats or specialist preparation may be required.

Nicotine Stain Blocking Primer

Nicotine contamination can leave yellow and brown stains on ceilings, walls, doors and other interior surfaces.

These stains can be difficult to conceal with ordinary paint.

Zinsser B-I-N helps seal nicotine stains, reducing the risk of discolouration appearing through the finished decoration.

It also helps lock in residual nicotine-related odours, making it particularly useful when renovating previously smoke-exposed properties.

Smoke Damage Primer

Smoke contamination can affect both the appearance and smell of a room.

Zinsser B-I-N provides effective stain blocking and odour sealing for smoke-affected surfaces.

This makes it particularly useful during suitable restoration and redecorating work following smoke exposure or fire damage.

Any necessary cleaning, structural assessment and remediation should be completed before priming.

Permanent Odour Sealing

B-I-N is designed to permanently seal unwanted residual odours within suitably prepared surfaces.

It is particularly useful for odours associated with:

• Tobacco smoke

• Nicotine

• Fire damage

• Pets

• Smoke contamination

Rather than simply masking odours with fragrance, the shellac-based coating acts as a barrier to help prevent residual smells from passing through the decorated surface.

The underlying source of any ongoing contamination must be removed or treated before application.

Water Stain Blocking

Water leaks and historic moisture damage can leave unsightly brown or yellow marks on ceilings and walls.

Zinsser B-I-N is an effective water stain blocking primer, helping prevent these marks from bleeding through subsequent paint coats.

It is particularly useful for:

• Water-stained ceilings

• Previously affected walls

• Historic leak marks

• Suitable repaired plaster surfaces

Before application, ensure the source of the leak has been repaired and the surface is completely dry.

Seals Timber Knots & Sap Streaks

Natural timber can contain knots, resins and sap that bleed through paint.

Zinsser B-I-N is particularly effective at sealing bleeding knots and sap streaks, helping prevent unwanted discolouration.

This makes it useful for preparing:

• Wooden doors

• Skirting boards

• Architraves

• Timber trim

• Wooden panels

• Suitable furniture

• Interior joinery

The shellac-based barrier helps create a more consistent foundation for the finishing coat.

Excellent Adhesion Without Sanding

Zinsser B-I-N provides excellent adhesion to many difficult surfaces without sanding, provided the substrate is clean, sound and suitable.

Its specialist formula helps finishing paints adhere to surfaces that may otherwise be difficult to decorate.

This can reduce preparation time on appropriate projects.

Loose coatings, contamination and damaged surfaces must still be addressed, and adhesion should be tested where compatibility is uncertain.

Primer for Glossy Surfaces

Glossy surfaces can be challenging because ordinary primers may struggle to achieve a reliable bond.

B-I-N adheres to many glossy and hard-to-stick substrates, making it useful for renovation work involving existing glossy coatings and other smooth materials.

Primer for Glass

Zinsser B-I-N can adhere to suitable glass surfaces, offering an adhesion-promoting coat for compatible decorative applications.

When painting glass, confirm that the full primer and topcoat system is suitable for the intended use, cleaning requirements and level of wear.

Seals Porous Surfaces

Porous substrates can absorb paint unevenly, causing inconsistent coverage and finish.

Zinsser B-I-N helps seal porous surfaces, providing a more uniform base for subsequent decoration.

This can be beneficial when working with suitable plaster, timber and other absorbent materials.

Excellent Enamel Holdout

Zinsser B-I-N provides excellent enamel holdout, helping create a consistent foundation for compatible enamel finishing paints.

By reducing uneven absorption into the underlying substrate, the primer supports a more uniform appearance.

This is particularly useful when preparing suitable doors, trim and woodwork.

Interior Primer for Walls & Ceilings

B-I-N is an excellent choice for interior decorating projects where staining, adhesion or odour sealing is a concern.

Typical applications include:

• Ceilings

• Interior walls

• Doors

• Door frames

• Skirting boards

• Architraves

• Timber trim

• Suitable painted surfaces

Its combination of stain blocking and fast drying makes it particularly useful during property refurbishment.

Exterior Spot Primer

Zinsser B-I-N is also suitable for exterior spot priming on compatible surfaces.

Potential applications include localised priming of:

• Wood

• Metal

• PVC

• Exterior trim

For outdoor projects, use B-I-N only for suitable spot-priming applications in accordance with the manufacturer's instructions.

It should not be treated as a general-purpose primer for full exterior surface coverage.

Fast Drying – 15 Minutes

Zinsser B-I-N becomes touch dry in approximately 15 minutes under suitable conditions.

This makes it particularly convenient for decorators who need to complete preparation and finishing stages efficiently.

Actual drying times may vary according to temperature, ventilation, humidity and coating thickness.

Recoatable in 45 Minutes

The primer can be recoated after approximately 45 minutes, allowing the next stage of decorating to begin quickly.

This is particularly beneficial when carrying out multiple repairs or spot-priming several stained areas.

Tintable to Mid-Tone Colours

Zinsser B-I-N can be tinted towards suitable mid-tone colours, helping prepare the surface for the chosen finishing paint.

Always follow Zinsser's recommendations regarding compatible colourants and tinting limits.

Zinsser B-I-N vs Zinsser B-I-N AQUA

• Demanding stain blocking

• Nicotine contamination

• Smoke and fire-related odours

Choose according to the substrate, staining severity, ventilation requirements and manufacturer's recommendations.

Both products provide excellent adhesion, but they are designed with different priorities.

Zinsser B-I-N is particularly suited to:

• Persistent stains

• Specialist stain-blocking applications

Zinsser Bulls Eye 1-2-3 is particularly suited to:

11. Allow approximately 45 minutes before recoating under suitable conditions.

12. Apply further coats where recommended for persistent staining.
