A method for improving the quality of a mastic coating system by using a selected tiecoat composition. The tiecoat is applied to a substrate in order to correct substrate problems which would cause premature failure of a mastic coating applied directly to the substrate. The mastic coating is then applied to the tiecoat to yield a superior mastic coating system.

Tiecoat for use with mastic coating applications

This invention relates to water-based coatings and caulking compositions for exterior surfaces which upon application quickly develop resistance to being washed out by inadvertant precipitation. These compositions comprise an aqueous dispersion of water-insoluble latex polymer prepared by emulsion polymerization, inorganic pigment dispersed with anionic polymer, and water-soluble salt of a multivalent complex ion having labile, volatile ligands such as zinc ammonium complex ion.

Washout resistant coatings

Disclosed is a plasticizing composition and caulks or sealants containing the same. The plasticizer is a combination of (1) a water insoluble adduct of ethylene oxide or propylene oxide and an alkyl phenol and (2) an ester type of plasticizer. Aqueous latex caulks are disclosed.

Mineral coating compositions for coating papers, the binder of which comprises a negatively-charged latex or an aqueous dispersion of an emulsion polymer, with or without an amylaceous binder, as the major portion thereof, and a relatively small amount of a water-soluble addition polymer having polymerized therein from 20% to 100%, preferably at least 40%, by weight of a monoethylenically unsaturated monomer having a primary, secondary, or tertiary amine group, such as an aminoalkyl acrylate, methacrylate, vinyl ether or vinyl sulfide, an N-aminoalkyl(meth)acrylamide, an N-acryloxyalkyl-oxazolidine or an N-acryloxyalkyl-tetrahydro-1,3-oxazine.
