Zinsser All Coat Problems

Zinsser All Coat paint is known for its versatility and the ability to adhere to a variety of surfaces. However, like all products, it can sometimes present challenges to those using it. One such problem arises when painting plastic-coated wooden bookcases.

The Problem

Using Zinsser All Coat on such surfaces can be tough. Some users have reported the paint leaving visible brush strokes after the first coat. Although the second coat might reduce the visibility of these brush marks, achieving a uniform, smooth finish can be a challenge.

Possible Solutions

1. Adjust Drying Time: One of the reasons for the appearance of brush strokes can be the quick drying time of the paint. Slowing down this drying time can be helpful. Although pure alcohol is recommended for this purpose, alternatives like meths or even vodka have been employed by users. This gives the paint more time to self-level, thereby reducing brush marks.
2. Change Application Method: If brush strokes are an issue, consider switching to a roller application. However, be aware that using a roller can introduce an ‘orange peel’ texture. The type of roller can also make a difference. Foam rollers, for instance, can expand and lose shape. Hence, it’s best to opt for reliable rollers, such as the Wooster rad rollers.
3. Additives: There are additives like floetrol that can improve the flow and leveling of water-based paints. In the case of solvent-based Zinsser All Coat, products like Penetrol or Owatrol can be used. These slow down the drying process and reduce the appearance of brush marks. However, be cautious and research beforehand, as there are concerns about potential yellowing effects.
4. Alternative Paints: If Zinsser All Coat is not giving the desired finish, consider switching to a different paint. Oil-based undercoats, for instance, are suggested for certain jobs and can be sanded down after drying to achieve a smoother finish. After sanding, a top coat of your choice can be applied.
5. Understanding the Paint: It’s vital to understand the difference between different types of paints. For example, Zinsser BIN is a shellac-based primer that dries quickly and is less prone to yellowing but can be challenging to apply with a high finish. On the other hand, the solvent-based All Coat is a different product and behaves differently.
6. Surface Preparation: If you’re not achieving the desired results with Zinsser All Coat, ensure that the surface you’re painting on is prepared adequately. A well-prepared surface can significantly impact the final appearance.

In conclusion, while Zinsser All Coat is a versatile product, ensuring the best results might require a bit of tweaking in the application method or additives. With the right techniques and tools, achieving a smooth and even finish is certainly possible. Always test a small section before committing to painting a larger area, and don’t hesitate to seek advice if unsure.
