Abstract
A method of applying a thermal barrier coat on an exposed side of a porous metal laminate which method includes the steps of spreading on the laminate an air-curable maskant to force maskant into the perforations in the exposed side, removing excess maskant from the exposed side so that maskant plugs remain in the perforations with tops generally coplanar with the exposed side, allowing the maskant to cure, directing sprays of bond coat and top coat incompatible with the maskant at the exposed side of the porous laminate to deposit a thermal barrier coat thereon but not on the maskant plugs, and removing the maskant plugs by thermal and chemical treatment or by chemical treatment alone.
