Sikaflex 1A is a premium grade, high performance, moisture cured, 1 component, non-sag elastomeric polyurethane sealant for forming permanent, water and weather resistant seals in exterior gaps and joints. Sikaflex 1A is excellent for small joints and fillets, windows, door frames, reglets, flashing, roofing detail applications, and many construction adhesive projects. Sikaflex 1A can beused in both vertical and horizontal joints where the maximum depth of sealant is 1/2 in or less.
This listing is for a choice of 12 (1/2 case) or 24 (full case) 10.1 fl. oz. cartridges that fit most caulking guns.
Also included is our AWF 2000 Pro Caulk Gun
Our 18:1 Pro Caulk Gun is a manual caulking gun that takes industry standard 10.3 oz. cartridges. Its durable design is perfect for frequent high volume use and features a pivoting barrel for seamless caulking around corners, curves, and tight spaces. The 18:1 mechanical advantage provides 18 lbs. of application pressure for each lb. of force applied to the trigger handle, perfect for applying high viscosity caulks and adhesives. In addition, our caulking gun features an instant pressure release tab, to prevent excess caulk leakage and a convenient pin to puncture the inner seal of the adhesive cartridge.
Use between 40° and 100°F, in cool weather store at room temperature for 24 hours prior to use. For best performance apply Sikaflex when joint is at mid-point of its expansion and contraction. Apply sealant with steady pressure, forcing the sealant into the joint. Sealant should be applied to both sides of joint, use bond breaker tape to prevent bond at base of joint. If the depth of the joint exceeds 1/2" use of a backer rod is recommended. Tool sealant to ensure full contact with joint walls and remove trapped air. Do not tool with detergent or soap solutions. Tooling results in a correct bead shape, a neat joint and maximum adhesion.
Allow 1 week cure when using Sikaflex 1A in total water immersion situations or before painting.
