Using Flexitec 2020 with Gutters

Using Flexitec 2020 with Gutters

In response to frequesntly asked questions regarding applying Flexitec 2020 to waterproof gutters; Here we summarise a few key points to help ensure your customers carry out a successful installation.



1. Coating Lined Gutters

If the gutter has an existing waterproof coating (such as GRP or single-ply) then you can treat it as you would a roof or balcony, i.e. applying Flexitec 2020 Primer (where required) & Resin to encapsulate the existing coverings.

2. Coating Metal Gutters

This is classed as a “non-standard” application and we always advise that you contact Res-Tec Technical Services to discuss suitability before advising your customers. There are a few important pointers that apply for most gutter applications including:

  • All lap joints and other points of expansion will require dis-bonding with masking tape prior to local reinforcement;
  • Res-Tec Metallic Primer will usually be required;
  • Areas of significant rusting should be treated with a proprietary rust-converter before priming;
  • Ensure the membrane can be taken up at least 150mm onto the gutter upstands.
