modified wood by Accsys Technologies ESSENTIAL COATINGS GUIDE FOR JOINERY MANUFACTURERS WHEN USING ACCOYA® WOOD INTRODUCTION IN LINE WITH BEST JOINERY PRACTICE AND COATING MANUFACTURERS GUIDANCE, IT IS IMPORTANT TO NOTE THE FOLLOWING GUIDANCE WHEN COATING ACCOYA WOOD. THIS IS SUPPLEMENTAL TO ADVICE FROM COATING MANUFACTURERS AND THEIR RECOMMENDED SYSTEM. Failure to adhere to this Guidance may result in variable coating performance and site problems. Please consult your coating supplier at all times. BEST PRACTICE FOR JOINERY MANUFACTURERS: applied joinery 1 A fully factory at least aIfprimercoating isis 6 strongly recommended. site finishing required, then and mid coat Dip and flow coat application of the first coating layer is widely practised in the Netherlands and Germany for all wood joinery and is particularly effective in forming all encompassing first coat. Coating manufacturer’s application methodologies and guidance should be followed with particular focus on avoiding cold coatings (should typically be above 15°C at application), film thickness and appropriate drying techniques / conditions. Coatings should be thoroughly cured in a moisture and temperature controlled environment and in line with coating manufacturers guidelines. This often involves overnight drying between layers and control is particularly important in colder months. An effective isolation barrier should be created for hardware that may be prone to corrosion. Please see the Accoya Wood Information Guide Section 06 for more details. should be applied in the factory and the top coat must be applied before the joinery gets wet on site. Accoya wood must be dry, clean and free from dust when coated. This is critical when brush applying top coats on site. Please see Section 03 of the Accoya Wood Information Guide for moisture testing techniques All opaque base coats must include an effective and well applied anti stain blocking primer. Translucent coating systems should contain an effective mouldicidal component to protect the wood from unattractive moulds and mildew. As with other wood types and being a natural material, the porosity of Accoya may vary. Therefore when applying translucent stains, it is advisable to test a sample area first. End grain sealers must be used throughout the joinery. 10 Coated joinery should be stored on site as per coating manufacturers guidelines.

GUARANTEED LEVELS OF DECAY RESISTANCE, TERMITE RESISTANCE AND DIMENSIONAL STABILITY APPLY TO ACCOYA WITH OR WITHOUT ANY COATING. Please note: coating formulations vary from supplier to supplier and processes vary depending on the application equipment used and end-product design. Formulations of some suppliers’ products vary by geography. Despite Accoya® wood’s excellent compatibility, we highly recommend having your coating supplier involved in the process as they have in-depth knowledge of their...
