1. Dependant on environmental conditions. Values attained at 23 °C and 50% rel humidity. Times given are reduced with higher (and increased with lower) surrounding and work surface temperatures.

Application Conditions

Apply only when atmospheric and substrate temperatures are greater than 5 °C. The surface of the substrate should be clean and dry and must be 3 °C above the dew point. If the surface is below or at dew point temperature then moisture can form at the surface and affect coating adhesion and curing.

Application Method

Remove the sachet from the external aluminium packaging. Manipulate Component A to achieve uniform colour consistency. Remove the separating rod allowing both components to mix together. Again, manipulate the mixed solution thoroughly; ensuring complete homogenous colour consistency is achieved.

Once ready, apply the mixed primer onto the prepared substrate in a flowing motion and spread using a squeegee. Specified coverage rates and even coverage can be achieved by rolling the primer using a nylon roller avoiding unnecessary accumulation of product.

The specified Elastoflex system can be applied above the primed surface when it is tack-free and dry. Depending upon atmospheric conditions, a minimum 12 hours will be required before overcoating.

Once applied, Elastoflex 2-Part Primer must be overcoated within 8 days of application, otherwise separation effects can occur.

If delays in overcoating are anticipated, Elastoflex Natural Quartz, may be broadcast over the wet primer to aid adhesion..

Personal Protective Equipment (PPE) should be worn.
