Sikaflex 1a Construction Adhesive comes in a 10.1 fluid ounce or 300ml tube. We recommend about 1 tube per sheet of approximately 10 square feet.
This compatible adhesive works for gluing zinc down to most substrates. The Service Range for Sikaflex 1a is -40F to 170F. We recommend a 1/8" triangle trowel to help spread the adhesive thinly and evenly.
Sikaflex is tack free in 2-4 hours, but needs to fully cure 5-7 days before moving it around or going outside, to prevent the zinc from pulling off of the substrate.
