Testing the performance of joinery coatings
In 1994 a large scale demonstration project has been started in the Netherlands, with the aim to study the performance of (less polluting) coating systems in practise. In the project 66 paintsystems (waterborne acrylics, high solids and traditional solventbased alkyds) were applied for maintenance of wooden window elements of 66 housing complexes. The project also contains field exposure and laboratory tests. Considered parameters are type of wood, details of the eleinent, pre-treatment, colour, application conditions and environmental situation. The pre-treatment of the window frame is the most important factor for the performance of the paintsystem. If the substrate have been prepared in a good condition before painting, there is nearly no difference in functional durability between the various types of paint tested. Some differences are shown between the groups of paint with respect to aesthetical properties like gloss retention and chalking. Waterborne paints show good performance in practise on technical as well as on aesthetical properties. There is a good correlation for gloss retention between field exposure and practise. HS products show a large variation in performance items. The effect of product improvement is not yet observable in the last years. The coming years of the project will reveal much more interesting information.
