Sikaflex-1a+ is a premium-grade, high-performance, moisture-cured, 1-component, polyurethane-based, non-sag elastomeric sealant. Sikaflex-1a+ can be used in green and damp concrete applications. Meets Federal Specification TT-S-00230C, Type II, Class A. Meets ASTM C-920, Type S, Grade NS, Class 35, use T, NT, O, M, G, I.
Sikaflex-715 is a one-component silane terminated polymer (STP) sealant with excellent adhesion and UV resistance.
Sikaflex® -221 is a high-quality multi-purpose non-sag 1-c polyurethane sealant/adhesive that cures on exposure to atmospheric humidity to form a durable elastomer. Meets approvals ASTM C920 types Sikaflex® -221 is tested and classified in accordance with ANSI/UL 723 “Test for Surface Burning Characteristics of Building Materials”. Honestly, your best bet, if you are having issues with the caulk, is to try the Eternabond. They have roof kits available that I will link below. Eternabond is a tape that is best if applied on a sunny warm day and needs to be rolled down really well to activate the two component sealant abilities to make sure that it lasts. Make sure to use an acetone cleaner instead of the mineral spirits because the mineral spirits will leave behind a residue.
