31 Incorporated Xtra-Seal Chemical Vulcanizing Cement (8 oz.) - 2 Pack Review: A Comprehensive Look

Introduction: Repairing Rubber and More

Xtra-Seal Chemical Vulcanizing Cement from 31 Incorporated is a two-pack contact cement designed for bonding rubber, neoprene, and other similar materials. It's a powerful adhesive ideal for repairing items like rubber boots, inflatable toys, pool liners, and automotive components. This review will delve into its performance, exploring both its strengths and weaknesses to help you decide if it's the right choice for your repair needs. This product is particularly beneficial for those needing a strong, long-lasting bond on materials that are difficult to adhere using standard glues or tapes. The two-part system ensures a powerful chemical reaction, creating a bond stronger than many competing single-part solutions.

The 8-ounce size of each tube in this two-pack provides ample material for several repairs, making it a cost-effective option for both DIY enthusiasts and professionals alike. While it's primarily used for rubber repairs, its versatility extends to other compatible materials, making it a handy tool to keep around the workshop or home.

Key Features:

  • Two-Part System: Provides a strong chemical bond for durable repairs.
  • 8 oz. Tubes (2 Pack): Offers a generous amount of adhesive for multiple repairs.
  • Versatile Application: Suitable for bonding rubber, neoprene, and other compatible materials.
  • Fast Drying: Reduces overall repair time.
  • Chemical Vulcanization: Creates a strong, flexible bond that resists degradation.

Pros:

  • Exceptional Bond Strength: Xtra-Seal delivers a surprisingly strong bond, surpassing many other contact cements in its class. Repairs made with this cement are robust and can withstand considerable stress.
  • Versatile Material Compatibility: Its effectiveness isn't limited to just rubber; it adheres well to a range of materials commonly found in household and automotive repairs, offering broad utility.
  • Ease of Use: Despite being a two-part system, the application process is straightforward, requiring minimal technical skill or specialized tools.

Cons:

  • Strong Odor: The cement has a pungent, chemical smell that can be quite noticeable during application and for a short time afterwards. Adequate ventilation is essential.
  • Limited Working Time: Once mixed, the adhesive has a relatively short working time. Careful and efficient application is crucial to prevent wasting the material.

I bought the Screwpop 3.0 because I needed something small for work that wouldn't bulk up my pockets. The design is super minimal which I love, and the fact that it uses standard utility blades is a huge plus because I hate sharpening knives. I will say, it took me a minute to get used to the sliding mechanism—it's a bit stiff at first—but after a few days it smoothed out. It’s way more secure than the version 2.0 I had before. Great little tool for the price point, highly recommend for anyone doing light EDC.

Sizing was way off for a medium. Way too small and the stitching started coming apart after two holes. Wouldn't buy again.
