Zinsser Allcoat, a versatile and well-known paint brand, has garnered attention among professional painters and decorators for its application on various surfaces, including UPVC, metal, wood, and more.
This review compiles feedback from decorators who have used Allcoat, highlighting its strengths and weaknesses based on their hands-on experiences.

Coverage and Application
Zinsser Allcoat is praised for its versatility, being suitable for a wide range of surfaces without requiring a separate primer. However, its coverage can be a point of contention. According to Jack Turner of Turner & Sons Decorating, Allcoat performed admirably on a UPVC door and window surround, previously brown and now black. Jack found Allcoat slightly better than Bedec, another popular choice among decorators.
Conversely, Patrick Murphy from Murphy Decorating strongly disagrees with using Allcoat on UPVC, arguing that it breaks down within 5-7 years and begins to flake, unlike solvent-based 2k coatings which last longer without fading or breaking down. Shane Evans and Kevin Bradley, however, maintain that with proper preparation, Allcoat can last for years without issues.
Durability and Finish
The durability of Allcoat is debated among decorators. Shane Evans from Evans Decorators and Eddie Lawton note that Allcoat remains robust on surfaces like door handles and thresholds for years, even withstanding everyday wear. However, Patrick Murphy and Chris Bennett argue that Allcoat is not suitable for high-traffic areas or surfaces prone to physical stress, advocating for more durable 2k products instead.
Ian Miller of Miller & Co Painting mentions that while Allcoat performs well for about five years on UPVC windows, it does eventually break down under direct sunlight, necessitating a fresh coat. This sentiment is echoed by several others, who emphasize that regular maintenance is a trade-off for its ease of use and aesthetic appeal.
Cost and Value
The cost-effectiveness of Allcoat is another area of mixed reviews. Mike Wilson from Wilson Decorating suggests that while Allcoat does the job, it may need to be reapplied every five years, which is standard for many paints. Shane Evans and Eddie Lawton argue that considering this, Allcoat still offers good value for its versatility and ease of application.
In contrast, some decorators feel that investing in more durable and longer-lasting alternatives could provide better value in the long run, despite the higher initial cost. This is particularly relevant for clients seeking a more permanent solution for their exterior surfaces.
Formula Changes and Improvements
While some decorators like Kevin Bradley have observed Allcoat’s consistent performance over the years, others feel that the product’s formula might have seen changes. There is a general consensus that while Allcoat has room for improvement, especially in terms of durability on UPVC, its versatility and ease of use keep it in regular use among many professionals.
Final Thoughts
Zinsser Allcoat remains a popular choice for many professional decorators due to its versatility and ease of application. However, its durability on surfaces like UPVC and its cost-effectiveness compared to more specialized products continue to be points of debate. For decorators willing to manage regular maintenance, Allcoat provides a practical and aesthetically pleasing solution.
For those prioritising long-term durability, exploring alternative products might be beneficial. Understanding the specific requirements and managing client expectations is crucial when opting for Zinsser Allcoat.
