Following the implementation of rules governing VOCs in paints for on site use on buildings, the British Coatings Federation is urging caution on using ‘green’ criteria to select paint systems.
In accordance with current legislation, coating manufacturers are producing safety data sheets and labels for their products. As a result, many ‘high performance’ coatings require the use of hazard symbols and accompanying explanation.
Hugh Williams, Technical Manager of the BCF said: “Specifiers and users have recently started to add up the hazards in the safety data sheet. As the hazard on the label is the sum of all the hazards, this is effectively double counting each individual hazard. This could have the negative result of preventing the use of some coatings in favour of what are perceived to be greener coatings.”
Mr Williams went on to state that products such as epoxies and polyurethanes can score badly if this system is used, and this could have a direct impact on the sustainability of structures where a less durable system has been used to repair damage or onsite as a coating system.
“A high performance system, such as an epoxy or polyurethane, is more likely to give greater durability than a lower tech system – potentially up to two or three times longer to first major maintenance.
“Taking into account energy consumption, access and VOC release involved in manufacture, supply and application of the repeat coating requirements of the less durable coatings, the BCF is urging specifiers and users to ensure they have a full understanding of all issues regarding VOCs and hazard labeling when choosing paint.”
