Product Data Sheet

Liquid Rubber ® will cover up to 46 square feet per gallon on a very smooth surface.  Normal coverage is 40-42 square feet per gallon on an average substrate. The required 20-mil film thickness will be achieved when the above spreading rate is used.

Cure Conditions:
The cure rate of Liquid Rubber® is temperature dependent; i.e. higher temperatures will accelerate the cure and lower temperatures will retard it. Contact with air is another requirement. If, for example, a rain shower develops before material has cured [material may still be wet] and water collects on the surface the following condition will prevail. Material that is still wet will prevent water from penetrating the film; however, the curing process will not begin unless material is exposed to air. The material under water will remain uncured until the water has evaporated and the surface again becomes exposed to air, at which time the curing process will begin.

Surface Preparation
Roof surface should be dry and free of dirt and loose gravel at time of application.

Mixing Directions
Proper incorporation and thorough mixing of the catalyst is critical to achieving desired cured film properties and should, therefore, be done with great care. Container is filled low to allow room for mixing as well as the addition of the catalyst. Insert mixing paddle in Liquid Rubber® and mix for approximately one minute so that material is moving uniformly and has formed a vortex. Slowly add catalyst into this vortex at a rate, which allows it to be incorporated without puddling. DO NOT pour catalyst on top of Liquid Rubber® prior to starting mixer. After all the catalyst has been added, the mixer (if hand held) should be moved in a circular fashion around the periphery of the pail as well as up and down to insure that the catalyst is completely and uniformly mixed. Periodically scrape the sides with a rubber or metal spatula to incorporate the stagnant layer of material adhering to walls of pail.
