Zinsser Cover Stain is an oil-based stain block, sealer and adhesion primer
Zinsser Cover Stain is a fast-drying, stain-killing oil-based primer that can be coated in one hour. It is a highly effective primer, sealer and adhesion primer that can be used on both interior and exterior surfaces. It is particularly useful for covering up stains, as it seals, blocks stains and provides excellent adhesion. It can be used on a variety of surfaces, including metal, wood and walls, and can be applied with a brush, roller or aerosol spray.
The Zinsser Cover Stain is especially recommended for covering up water stains. One user reported that, after fixing a leak in their ceiling that had caused water stains to run down the wall, they scraped and cleaned the affected areas before applying the Zinsser Cover Stain. They then finished the area with a joint compound and put on another coat of the sealer. A couple of days later, they repainted the ceiling and wall. Several months later, there was still no sign of the stain bleeding through, and the area looked brand new.
The product is also praised for its coverage, with one customer noting that it covered one wall in their living room. Another user reported success using the primer on a laminate wood dresser, requiring only one coat of primer and one coat of paint.
However, the Zinsser Cover Stain does have a strong smell, which some customers find unpleasant. It also adds texture to surfaces, which may be undesirable in some cases. To avoid this, it is recommended to sand the surface after applying the primer and to use a shellac to smooth out the texture. Despite these potential drawbacks, the Zinsser Cover Stain is a highly effective and versatile primer, sealer and adhesion product that can be used to quickly and easily prepare surfaces for painting.

It is suitable for both internal and external use
Zinsser Cover Stain is a versatile product suitable for both internal and external use. It is an oil-based stain block, sealer, and adhesion primer. It can be used on bare timber, stained or varnished timber, and to prime old gloss or satinwood. It is touch-dry in 45 minutes and can be recoated in 2 hours, making it a convenient option for projects with time constraints.
While it is suitable for both indoor and outdoor use, it is important to note that it has a strong odour and adequate ventilation is necessary during application. The product is also available in an aerosol form, which can be beneficial for certain applications.
When using Zinsser Cover Stain, it is recommended to apply it with a roller or brush, as it will show brush and roller texture. If a smooth finish is desired, a light sand between coats can help achieve this. Additionally, a good topcoat will buff out any texture.
It is worth mentioning that while Zinsser Cover Stain is effective for blocking stains, there are alternative products available, such as oil-based undercoat or Zinsser BIN, a shellac-based paint, which offer similar performance with faster drying times. However, these alternatives may not be suitable for all situations, as Zinsser BIN, for example, dries very brittle and is not recommended for outdoor use or steamy environments.
In summary, Zinsser Cover Stain is a reliable and versatile product for both internal and external applications. It offers good stain-blocking capabilities, adhesion priming, and convenience due to its fast-drying nature. However, it is important to manage its strong odour and be mindful of its texture, which may require additional steps for a smooth finish.

It is touch-dry in 45 minutes and can be recoated in 2 hours
Zinsser Cover Stain is an oil-based stain block, sealer, and adhesion primer. It is suitable for both internal and external use and can be used to prime bare timber. It is a versatile product that can be coated over a full ceiling or wall. It is also an excellent option for stained or varnished timber that needs to be painted.
When using Zinsser Cover Stain, it is important to note its drying time. The product is touch-dry in 45 minutes and can be recoated in 2 hours. This quick drying time sets it apart from other products, such as oil-based undercoat, which has a 16-hour recoat time. The fast drying time of Zinsser Cover Stain allows for efficient work, as you can easily paint over it on the same day.
While Zinsser Cover Stain is a popular choice among professional decorators, it is important to consider its limitations. The product has a strong odour, and it is recommended to ventilate the room during and after application. Additionally, it can result in a bumpy or textured finish, which may require light sanding to smooth it down.
To ensure the best results with Zinsser Cover Stain, it is advisable to dilute it with white spirit before application. This will help to loosen the product and improve its flow. It is also important to allow adequate drying time before recoating. While the product is touch-dry in 45 minutes, waiting the full 2 hours before recoating will ensure proper adhesion and a smoother final finish.
In summary, Zinsser Cover Stain is a versatile and effective product for blocking stains and priming surfaces. Its quick drying time of 45 minutes to touch-dry and 2 hours to recoat makes it a convenient choice for painting projects. However, it is important to be mindful of its strong odour and potential texture issues. By following the recommended application techniques and allowing sufficient drying time, you can achieve successful results with Zinsser Cover Stain.

It can be painted over with most types of emulsion, but cheap contract matt may cause flashing
Zinsser Cover Stain is a versatile product that can be used as a stain block, sealer, and adhesion primer. It is suitable for both interior and exterior use and can even be used to prime bare timber. The product is touch-dry in 45 minutes and can be recoated in 2 hours, making it a convenient option for painting projects.
While Zinsser Cover Stain provides a great base for most types of paint, it is important to consider the type of paint you plan to use for the topcoat. Zinsser Cover Stain can be painted over with most types of emulsion paint. However, if you plan to use cheap contract matt emulsion, you may encounter flashing issues. Flashing occurs when the topcoat of paint does not adhere properly to the primer, resulting in an uneven or patchy appearance.
To avoid flashing when using Zinsser Cover Stain, it is recommended to choose a different type of emulsion paint for your topcoat. High-quality alternatives such as vinyl matt, durable matt, or eggshell are less likely to cause flashing and will provide a more uniform finish. These types of paint are designed to adhere well to primers like Zinsser Cover Stain, resulting in a smooth and consistent appearance.
It is worth noting that Zinsser Cover Stain can add texture to your surface. If you prefer a smoother finish, consider sanding the primer before applying your topcoat. A light sanding with an orbital sander or fine-grit sandpaper can help create a smoother base for your paint. Additionally, ensure that the Zinsser Cover Stain is completely dry before applying paint. The recommended drying time for Zinsser Cover Stain is 2 hours, but it is always best to allow ample time for the primer to cure fully.
By following these guidelines and choosing the right type of paint, you can achieve a professional-looking finish and avoid any issues with flashing when using Zinsser Cover Stain as your primer. Remember to properly ventilate the area when working with oil-based products like Zinsser Cover Stain to minimise any unpleasant odours.
