Keep Coremat® Xi away from direct sunlight, therefore store Coremat® Xi in the original bag. This will ensure proper functioning of the resin indicator. Please note that the resin indicator is not a guarantee that sufficient resin has been applied, but strictly a control mechanism to identify dry spots. Always check resin content.
