Apply a light coat of RP1 Primer, allow to dry.Then after a further de-nib apply a full even coat of the RP1 top coat & allow to dry.


When force drying, 30 mins flash off (Very important to avoid increased gloss levels), 60 mins at 35-40c then 30 mins air cooling before sanding. Temperature times will vary with coating thickness. As the catalyst contains isocyanate the use of air-fed masks is required whilst spraying. Please ensure that the total system dry film thickness (DFT) does not exceed 150 microns. Always lightly sand between coats to assist adhesion. Maximum 2 coats in any 8 hours. Catalyst should be used within 6 weeks of delivery. Once opened, Catalyst MUST be used within 7 days
