Myth busting: The truth about Polyform

There are many aspects of my role as Operations Director that I enjoy. One of my favourite aspects is providing free training and support to our customers around the Country. It’s important for the business to connect with its end users and it gives me the opportunity to get feedback on our products, correct misconceptions and explain the truth about Polyform.

Over the years, this is the one of the key things that has stood out. At every training session I give, I ask, “does anyone have any experience of our products?” and each time, someone will say to me, “yes, but…” and I wait, listening to what the person says. I find it interesting that there are so many different misconceptions about our products, particularly Polyform.

I thought it might be useful to write down the most frequent misconceptions to set the record straight and explain the truth about Polyform. Please note, this list is not exhaustive. The best way to find out how to get the most out of our products is by attending a free training session.


Myth one: I don’t use Polyform because it’s messy and gets everywhere

Answer: There are so many reasons why people say this. The easiest way to debunk this myth is by attending a training session as I often hear this statement from users who have not received formal training.

I’m confident that by the end of one of our training sessions, your opinion will have changed. During every training session MW Polymers provides, we go through the preparation stages required before beginning a repair. We also include tips and tricks for how to complete a repair and stay clean.

As part of each training session, I give a practical demonstration on the application of Polyform. I stand there in my suit and don’t get any Polyform on my clothing or shoes. Our top tips for staying clean when applying Polyform are:

  • Ensure you have everything you need to hand
  • Once you are ready to begin, put both pairs of gloves on (this will prevent you having to change gloves half way through the repair process)
  • Ensure you have the correct consistency when mixing the two-parts together

Having the correct consistency will aid the application process as you ideally want to remove the Polyform out of the bucket in 3-4 scoops.


Myth two: I’ve been told Polyform is only classed as a temporary repair, is this correct?

Answer: No, this is not correct. Approved to a stringent regulatory standard, Gas Industry Standard (GIS) LC8-1, Polyform is designed to repair low and medium pressure pipes up to 2 bar. The LC8 specification requires products to achieve a 50-year life guarantee as a minimum. This means Polyform is classified as a permanent repair solution. For clarification, Polyform will far outlast the required lifetime period, but 50 years is the standard set by the industry for this specification.


Myth three: I find it easier to apply Polyform without the spatula using my hand

Answer: This is not okay. Polyform must always be applied using the spatula provided. If you don’t use the spatula, you can’t apply a consistent coverage. This may potentially create problems for the repair and the individual. Although Polyform will not cause burns to the skin, there is an exothermic chemical reaction taking place when the two-parts of the resin are combined. If you apply Polyform by hand (with or without a glove on), your skin may feel uncomfortable.

We provide gloves within the kit and strongly advise all items are used.  A spatula is included within the kit because this is the easiest way to apply it within the quick time frame required.

If you are unsure how to apply Polyform, or require more information, you can get in touch with us via the website to arrange a training session.


Myth four: I never know how long it will take for the product to cure because the timings are inconsistent

Answer: If you are facing an inconsistent cure time, this is because the base and activator are not being properly mixed or shaken before beginning the mixing process. As a two-part resin, both parts need to be agitated before combining the two parts. Completing this process will ensure the best results are achieved.


Myth five: I can’t use Polyform when it’s frosty

Answer: You can use Polyform regardless of the weather, however, there are some important points to remember. Polyurethane resins are highly incompatible with water. If it is raining or the repair area is filling with water, dig a sump hole to drain it.

The temperature outside can affect the cure. You may find Polyform is slow to cure when it is cold and fast when it is hot. This is not just dependent on the outdoor conditions, but also the storage conditions. For instance, if a bucket of base and activator is left overnight in a cold van, it is worth warming it up a bit before beginning the mixing process. Once this step is complete, you can mix the contents of the bucket until it forms the correct consistency.
