Please note : When using the primer on spot-primed areas with a porous surface it may show through if the topcoat has poor coverage. This also applies to many ceiling paints and shiny enamels, it is recommended to only use a topcoat with good coverage.

For the best results, ensure surfaces to be coated are sound, clean and dry, and free from all defective or poorly adhering material such as dirt, grease, paint or adhesives. If needed, clean surface using Zinsser Universal Degreaser and Cleaner, rinse thoroughly and allow surface to dry completely.

1. Take special precautions during surface preparation of pre-1960s paint surfaces over wood and metal as they may contain harmful lead
2. Remove and treat any mould and mildew on interior surfaces using Zinsser Mould Killer and Remover
3. For exterior surfaces treat mould with a exterior mould killer and remover
4. Remove any peeling and or unsound coatings. sand any remaining paint film edges smooth
5. When priming over stained areas, first attempt to remove as much stain as possible by washing, sanding and scraping
6. Allow surface to dry completely before priming
7. Substrate moisture content should not exceed 12%. New plaster which is polished or dusty should be sealed first with Zinsser Gardz
8. Degrease new galvanised steel with Zinsser Universal Degreaser and Cleaner ensuring all traces of oil and surface contamination are removed

Always do a test area before starting any project to check product suitability and effectiveness. Follow the manufacturer's instructions on the tin at all times.

Only apply at temperatures ranging between 7°C and 32°C with a relative humidity of less than 85%. Do not apply in direct sunlight or if condensation, rain, fog, frost etc, is likely to affect the freshly applied primer coat.

1. Shake or stir thoroughly before and periodically during use
2. Apply Zinsser B-I-N with a good quality natural or synthetic brush, microfibre roller, applicator pad or spray gun
3. Apply 1 full coat to prepared surfaces. A second coat on very porous surfaces or heavy staining may be necessary
4. Allow 45 minutes between coats
5. Fully cured in 5 - 7 days

Spray gun Guidelines

• Normal use: Thinning is not required, however, if necessary, add no more than 5% clean water. Do not thin if using for stain, knot or odour blocking
• Airless sprayer: Use tip size 0.015 - 0.017 at pressure 1700 - 2200 psi

Dry Time

At normal temperatures Zinsser B-I-N is touch dry in 25 minutes and can be recoated in 45 minutes. Lower temperatures, high humidity, and the addition of tint will prolong the dry and cure time of the product. For knots and stains, allow 2 hours to dry. When sealing water stains, some stains may appear in the primer as it dries, this is normal. Stains will be locked in the primer film and will not bleed into the topcoat.

As much as this is suited for this type of project, it would depend on what is on the timber now and what you plan on putting on the timber after, as to whether this would be suited. Why not call out Woodcare Experts on 01303 213838 for more tailored advice.

B-I-N is a shellac-based primer and sealer. The Aqua does a similar job but has a water-based formula. The classic B-I-N has a very high VOC and can be used in freezing temperatures. It is mainly used as a interior product but can also be used externally as a spot primer.

Absolutely, give the surface a key and clean it off before application.
