Decorators always seek products that simplify their workflow while delivering exceptional results. Among these, fillers and caulks are crucial staples for creating seamless finishes. FC1, a new product from C-Tec, promises to be both a reliable caulk and a filler. But does it live up to the hype? Let’s explore the key feedback from professional decorators to determine if FC1 is a game-changer or just another tube on the shelf.
First Impressions
Many decorators were intrigued by FC1’s claim to combine filler and caulk capabilities. Gary M summed up initial expectations well, noting its application was “flawless,” and the finish was impressive after painting. However, several users quickly identified that while it excels as a caulk, it struggles to meet the demands of a robust filler.
Performance: Caulk vs. Filler
As a Caulk:
The overwhelming consensus is that FC1 performs exceptionally as a caulk. Decorators like Paint Spartan and Peter K praised its smooth application, minimal shrinkage, and excellent adhesion. Even in challenging scenarios, such as wide gaps or intricate mouldings, the caulk maintained its integrity. Aidan W, who tested it on large gaps, noted it didn’t slump overnight and took paint beautifully without crazing—a major win for time-pressed professionals.
FC1’s flexibility and ability to be sanded were standout features for many. For instance, Gary M appreciated its ability to square off door frame edges where traditional caulks would leave a rounded finish. Kevin G echoed this, saying FC1 was “faster to apply” and performed “just as well” as his go-to caulk, with no cracking or shrinkage after drying.
As a Filler:
The filler aspect of FC1, however, sparked mixed reviews. While it handles fine gaps or minor imperfections well, its limitations became apparent with deeper holes. Paint Viking felt it was “not a filler” in the traditional sense, noting that curing times for larger applications could stretch to over 24 hours. Tony W shared similar feedback, explaining that FC1 filled cracks “to a point” but still required skimming for a perfect finish.
Drying Time
One recurring critique was the drying time. Although marketed as paintable within an hour, several decorators, including Paul O and Robert T, found this claim inconsistent, especially for thicker applications. This might deter decorators who need quick turnaround times. However, once dry, FC1’s performance redeemed itself by providing a durable, paint-ready surface without crazing.
Price and Value
At £3.99 to £4.74 per tube (depending on the retailer), FC1 is priced higher than many standard caulks. This led to divided opinions on its value. While some decorators, like Paint Spartan, felt it was “worth every penny,” others, like Sam W, were less impressed, saying it offered little to justify the premium price.
For those who prioritise quality, the price point seemed acceptable. Jimmy P noted it was “decent gear” that performed better than cheaper alternatives, and Jason G deemed it a reliable option even at a higher cost.
Pros and Cons
Pros:
- Smooth application and minimal shrinkage.
- Excellent adhesion to various surfaces.
- Sandable for refined finishes.
- No crazing when painted over, even with dark colours.
- Versatile and reliable as a caulk.
Cons:
- Underwhelming as a filler, especially for deeper gaps.
- Longer drying times than some competitors.
- Higher price point compared to traditional caulks.
Key Comparisons: FC1 vs Toupret
Toupret has long been a trusted name for fillers, known for its versatility and ease of use. Decorators like Aidan W admitted they wouldn’t switch to FC1 for filling because of Toupret’s proven reliability. While FC1 stands out for its caulking properties, Toupret still reigns supreme in filling deeper imperfections and offering consistent drying times.
Final Verdict
FC1 is undeniably a high-performing caulk with added versatility. Its ability to deliver smooth finishes, combined with sandability and paint adhesion, makes it a strong contender for decorators seeking reliable caulking solutions. However, its shortcomings as a filler and its relatively slow drying time mean it’s unlikely to replace Toupret or other specialist fillers in the trade.
Would we recommend FC1? Absolutely—as a premium caulk. But if you need a heavy-duty filler, stick to the trusted brands that specialise in filling applications. With FC1, you’re getting a product that excels in specific scenarios but falls short of being the all-in-one solution it claims to be.
