Can I put EpoxyMaster epoxy over pre-existing paints or other coatings?
EpoxyMaster is not recommended for application over existing coatings because the existing coating will inhibit bonding of the EpoxyMaster epoxy coating to the concrete floor. Floors that have existing coatings should be stripped, etched, diamond grinded or shot blasted to remove as much of the coating as possible. In cases where the coating cannot be removed, a sanding of the floor using an orbital sander can provide a “profile” for the EpoxyMaster epoxy to adhere to.
