Scope of Use
  • JSC has worked on specifically developing a product to cater to the New Zealand market that is suitable for the unique and varied climatic conditions. JSC Scumble® is perfect for all exterior timber cladding, soffits, timber joinery and decorative screens. 
  • JSC weatherboard will be factory coated using the JSC factory coating system. This involves coating weatherboards under controlled conditions using our vacuum coating technology. Vacuum coating ensures 100% coverage over the entire surface area of any profile in one pass. Factory coated product is delivered on-site dry, well stacked, and ready for installation.
  • 10 colours to choose from with high-quality pigments & UV inhibitors. A clear coating option is available that is free of colour pigments for applications where the raw beauty of the timber is the key requirement.
Limitations on Use
  • This product is to be used on exterior applications only
  • Drying times and coverage rates may vary due to a variety of factors such as seasonal temperature, the timber porosity, moisture content (below 18% required), the timber type, and previous coats applied
  • Avoid applying excess product to the surface as it will not dry. To deliver the optimum quantity, JSC recommend a trial application on offcuts prior to undertaking the actual coating
  • Due to the fast-drying nature of JSC Scumble, application tools may become clogged. Therefore, a periodic rinse in Isopropyl alcohol is recommended
  • Unlike paints, it is difficult to predict precisely how the coating will look once applied, as the appearance of stain coatings is influenced by the finish, grain, and colour of your chosen timber specie. Due to timber being a natural product, the timber specie and grain varies as will the finished product
Other Performance Attributes
  • Longer lasting
  • Fast drying
  • Weather resistant
  • Ease of maintenance
