INSTRUCTIONS FOR USE

TO MIX BY HAND: Proportion out components according to parts by weight or volume ratio into a non-reactive container (polyethylene, polypropylene or metal de-rimmed can). Container should be about five times larger than the volume of mixed material. Mix components very thoroughly, preferably with a metal spatula, scraping the sides and bottom of the container to incorporate all material.
Remove the air entrapped during mixing by placing the container of mixed material into a vacuum chamber. Under vacuum, the level of mixed material will rise and then drop with strong, bubble-breaking action. Do not allow the contents to rise over the top of the container while removing the air. Allow the material to de-gas (de-air) until the liquid level drops and bubbling is minimal. At this point, release the vacuum. If working time allows, transfer material to a clean container, without scraping the sides or bottom, before applying. If working time does not allow transfer, material should be used immediately.
