PPG announced that it has introduced PPG MACHINECOAT™ WB (waterborne) weathering stain for new commercial cedar shingles. The low volatile organic compound (low-VOC) stain is an alternative to traditional solvent-based PPG Machinecoat alkyd weathering stains.
Whitish-gray when machine-applied to new cedar shingles, PPG Machinecoat WB weathering stain lightens over a six-to-nine-month period, gradually assuming the appearance of aged cedar that blends naturally into its surroundings. The faux-weathered appearance lasts until the cedar begins to age and fade naturally.
PPG developed the weathering stain to satisfy demand from producers of commercial cedar shingles for an environmentally sustainable product that creates the finished look homeowners want.
“Cedar siding has been popular for decades because it offers a natural look that grows more appealing as the wood ages,” said David Jeffers, PPG national segment manager, North America. “This stain helps cedar shingle manufacturers and industrial coaters deliver the authentic wood look homeowners desire in a low-VOC formulation.”
PPG Machinecoat WB weathering stain provides a uniform, weathered appearance when applied to white cedar shingles and air dries in approximately 30 minutes in ambient conditions. It also can be force-dried under suitable conditions.
