ElastaHyde QS – Quick Set Formulation: ElastaHyde 720 and 790 are available in a “Quick Set” formulation. This special formulation aids in the application of ElastaHyde when damp, wet or rainy weather is expected before the ElastaHyde has proper time to completely dry. ElastaHyde QS will set up rapidly, within 15-20 minutes, and resist moisture in the form of dew, fog or even heavy rain. Once set up it will not wash off or dilute. By quick setting the product becomes very firm and stable, but it is not completely dry and must be allowed to cure as normal.
