Application steps

SUBSTRATE PREPARATION

All surfaces must be sound, clean, dry, and free of frost, oil and grease. Curing compound residues and any other foreign matter must be thoroughly removed. A roughened surface will also enhance bond.

   

Detailing Joints, Seams, Cracks and Penetrations

  1. Before application, fill or repair any cracks larger than 3/4 inch before application with appropriate repair material.
  2. Fill and tool all cracks, joints and seams that measure up to 3/4 inch in width with Sikaflex®-102 EverFlash Membrane. Keep the nozzle in the sealant; continue on with a steady flow of sealant preceding the nozzle and avoid overlapping of sealant to eliminate entrapment of air.
  3. Apply a thick bead of Sikaflex®-102 EverFlash Membrane to all sheathing joints, seams and cracks. For plywood knots, checks, cracks, separations or surface irregularities, apply a spot of Sikaflex®-102 EverFlash Membrane and trowel smooth.
  4. Apply and tool a cant bead of Sikaflex®-102 EverFlash Membrane around wall penetrations and fasteners.
  5. Use a dry putty knife, trowel or spatula to tool and spread the product. Spread 1-inch beyond seams at each side of the window (or door) to a thickness of 12–15 mils.

Priming is not usually necessary for anodized aluminum, steel, non-absorbent materials such as glass, ceramics, stoneware and tiles. Consult Technical Service at 1-800-933-SIKA for additional information on priming.
