Effisus EasyBolt
Efficient sealing of metal roof bolts

Fast bolt sealing
Due to the high variance in the screw’s installation, some are torqued too lightly, some too hard, some over inclined, all leading to potential seal breaches. This is aggravated by structural movements, differential thermal expansion and over time screw corrosion and washer degradation.
Traditional solutions using silicone and similar sealants have limited longevity and challenges to yield consistently effective installations. Effisus EasyBolt is available in multiple colors, easy to install with no need for primer and reduces corrosion development around the screw. Its high-elastic membrane and EPDM protection over the screw’s head creates a perfect seal around each screw and is a long-lasting solution to these leakage hot spots, resisting to UV exposure and low/high temperatures.
For a comprehensive offering against water intrusion in metal roofing bolts and screws, when the metal roofs are frequently accessed for maintenance, Effisus Bolt Protect, due to its hard capsule, resists even frequent stepping on the bolts/screws.
