Undertake an initial test for the presence of moisture in the subfloor using a radio frequency moisture meter such as the Aquant Protimeter. If moisture is present, investigate further.
Confirm and accurately measure the moisture levels present using a F. Ball Digital Hygrometer. If the relative humidity is below 75% it is safe to proceed with fitting. If above 75% RH go to step 3
If relative humidity is above 75%, treatment is required. Up to 85% RH use two coats of Stopgap F78 or Stopgap Isolator Membrane. Above 85% RH use F77, F78 or Stopgap Isolator Membrane in accordance with recommendations on the latest Technical Data Sheets.
