Can Kal-Kore® veneer plaster baseboard be painted like wallboard?
No. Kal-Kore is a plastering base having a blue absorptive face paper surface designed to permit rapid trowel application and strong bond of gypsum veneer plaster. National Gypsum Company has no test data on direct application of paint products to the Kal-Kore plaster base. Any such application, with or without a sealer, is at the risk of the customer.
