Resin flooring framework - feedback wanted on substrate priming

With the Resin Flooring Network website launched and the 3-month review period for the draft framework underway, I’ve put together a series of posts aimed at encouraging input from industry stakeholders.

Over the coming weeks I’ll be posting the core elements of the draft framework so that everyone can see what the training program looks like so far and, more importantly, how they might contribute to developing it further.

The fourth element is substrate priming, with the proposed Scope, Key Learning Outcomes, Theoretical Assessment Criteria and Practical Assessment Criteria detailed below.

Substrate Priming


This module covers the application of “pre-flooring” coatings such as primers, sealers and moisture barriers, which are generally applied at less than 200 microns/8 mils total dry film thickness. In some cases, these products can be considered light-duty floors, aimed at occasional foot traffic, e.g. rubber-wheeled trolleys.

Key Learning Outcomes

To be able to select and apply a suitable primer, sealer or moisture barrier, taking into consideration conditions, substrate and resin flooring system used.

Theoretical Assessment Criteria


  • Why primers, sealers and moisture barriers are used and the roles they play.
  • The product selection and application process for primers, sealers and moisture barriers.
  • The importance of re-coat window in the application of these products (and resin flooring in general).
  • The importance of achieving full coverage in the application of these products (and resin flooring in general) and how to detect areas of insufficient coverage.

    Practical Assessment Criteria


    • The effective application of suitable primers, sealers and moisture barriers.

    We want your feedback!

    This draft is intended as a starting point for discussion only and we welcome honest feedback from all stakeholders – the good, the bad and the ugly! If you’d like to suggest any changes or additions to improve this element of training, please add your comment on the dedicated Resin Flooring Network page –

    Take care and keep smiling,
