Do I need to apply a plaster bonding agent prior to using Presto Patch to repair wiring channels in plaster, which reach the underlying wood beam?


Thank you for posting your inquiry. While primer is not required by DAP, it would certainly improve overall performance (product adhesion to the substrate/s). Should you have any questions or require further assistance, please feel free to contact DAP’s Technical Customer Service Department at 888-327-8477.
