Assessment of desired performance life and provision of remedial recommendations for wood coatings & treatments. 

BM TRADA has a wealth of experience in diagnostic work in wood coatings and treatments determining the causes of coating failures and wood decay on exterior joinery including cladding. We can provide advice on optimum wood treatments and schedules in order to achieve a desired performance life and are able to advise on specific remedial and/or preventative strategies to help extend the performance life of wood joinery. 

Our wood coating and treatments services in this area more typically involve carrying out a site inspection followed by more detailed diagnostic laboratory work.

BM TRADA wood coating and treatment services include the following:

  • Determination of dry film thickness to establish coating loading's achieved and verification of number of coats applied
  • Provision of advice on the adequacy of the coating application and /or the coating specification used
  • Determination for the presence of wood preservative treatment
  • Diagnostic investigations into the cause or causes of blistering, coating de-lamination, staining disfigurement and other in-service coating issues
  • Provision of guidance on the selection of appropriate coatings, wood treatments, and sealants to extend the lifespan of wood joinery
  • Provision of advice on appropriate and cost-effective remedial strategies in the event of coating failures. 

We can provide authoritative consultancy support in the resolution of disputes and have represented a range of commercial and private clients in the past. However, operators are required to undertake measures designed to check whether timber / timber products they ‘handle’ is legal to comply with the EUTR. Operators are required to undertake due diligence either by developing their own due diligence system (DDS) or using one provided by a third-party. 

What is timber species verification?

The methods employed to verify wood species involves examination of the anatomical features of the sample in question using microscopy. These anatomical features are compared against those for timbers claimed to have been used in accompanying documentation. This is important where a product is made up from more than one component.

Next, the microscopic features of woods used in the product are identified, recorded and matched with those of authenticated reference samples, thousands of which have been collected by us for more than 70 years. 

Operators are required to provide botanic names for species contained in their products. Commercial or local names for timbers while acceptable to the trade may be misleading and should not be used in the context of EUTR. 

It should also be recognized that in the past the geographic origin of timber provided an indication of species it was likely to be. However, since many commercial timbers are now grown outside the regions where they originate geographic origin is less useful.
