TWP 200 series - 1 Gallon
The 200 series is a high solid, heavy duty penetrating coating. The 200 series is designed for extending the service life of shakes and shingles. The primary function is to enhance structural integrity and appearance of aged roofing. This coating will minimize grain cracking, surface erosion, cupping, water absorption and surface attack from mildew and algae. Although this is a penetrating coating a residual surface film is highly resistant to destructive organisms. TWP 200 series restored lubricity and flexibility to brittle shingles.
