As the UK’s premier flooring product specialist, F. Ball has developed a specialist market leading range of high performance products, providing a wide range of tried and tested subfloor moisture control solutions.
The technical experts at F. Ball know that the way to ensure the lasting performance of a new floorcovering installation is to deal with any damp or moisture problems from the outset. If not dealt with successfully, not only will the appearance of the new floorcovering be ruined, but the very fabric of its construction and ultimately the integrity of the installation, will be compromised too.
Every specifier and contractor knows the old maxim ‘time is money’, so when there are products that can deliver better economy, are easier to apply, and provide time-saving solutions guaranteed to perform perfectly, they’re bound to attract a lot of attention.
Accurate moisture testing in accordance with the British Codes of Practice BS 8203, BS 5325 and BS 8201 is essential to determine the Relative Humidity (RH) level within a subfloor. F. Ball recommend moisture levels be checked accurately by use of their approved Digital Hygrometers. An indication of the presence of moisture can be quickly determined using the Protimeter Aquant or Protimeter Moisture Measurement System (MMS).
If the relative humidity is below 75% it is safe to proceed with a fitting. Where the RH is above 75%, the installation should not proceed, as excess moisture in the floor could result in blistering of the floorcovering or complete failure of the flooring installation. This may result in expensive and lengthy remedial work, including the possibility of a costly ‘rip out’. Visual inspection is insufficient as a surface can appear dry while excess moisture is still present. Once levels have been accurately measured and confirmed, you then need to apply the best Waterproof Surface Membrane available. If the RH measurement is above 75% and up to 92%, F. Ball recommend to use one coat of Stopgap F76 or Stopgap Isolator Membrane. If the RH is above 92%, F. Ball recommend to use Stopgap F77, F78 or Stopgap Isolator Membrane. (Wood floor installations should be a maximum of 65% RH, consult the wood floor manufacturer)
The treatment of subfloor moisture problems is very serious to consider before beginning any major flooring project. For further information on the complete F.
