If you are doing a more coarse application of Venetian plaster, you can add it to Cera Wax and trowel it on as a last step. It can also be added to Acrilak or the Metallic Clear Coat and rolled on most porous finishes.
We do not recommend adding Krystalia powder to plasters or metallic paints. It may cause scratches in the final coat. It works best in Clear coat sealants as an added effect.
