Method for coating wet surfaces or surfaces immersed in water

A method of caulking wet or damp masonry, comprising

• blending 80 parts (A) comprising a low molecular weight polyepoxide having at least two vic-epoxy groups and containing only members of the group consisting of C, H, O, and Cl, with
• 100 parts (B) consisting essentially of
• 500 parts of a reaction product between
• 70% N-oleyl propylene diamine and 30% said polyepoxide,
• 500 parts calcium carbonate,
• 90 parts asbestos fiber,
• 90 parts titanium dioxide pigment,
• and forcing the mixture before it cures into the areas to be caulked.

A method of coating a structural material with a wet or moist surface including a surface immersed under water, comprising the steps of:

• a. thoroughly mixing, to provide a non-aqueous coating composition:
• A. an epoxy resin consisting of a polyepoxide having a plurality of vic-epoxy groups and containing only members of the group consisting of carbon, hydrogen, oxygen and chlorine, and
• B. a stoichiometric amount of an amine curing agent which is substantially insoluble in water and not water-sensitive and chosen from the group consisting of
• 1. an amine of the formula ##STR10## where R.sub.1 is chosen from the group consisting of ether radicals of which one of the alkyl or alkylene radicals has at least eight carbon atoms, and
• 2. a condensation product of a small proportion of a polyepoxide having a plurality of vic-epoxy groups and containing only members of the group consisting of C, H, O, and Cl, and a large proportion of a fatty amine of the formula:
• ##STR11## where R.sub.2 is chosen from the group consisting of alkyl radicals having at least eight carbon atoms and ether radicals of which one of the alkyl or alkylene radicals has at least eight carbon atoms,
• b. applying said coating composition to said surface, and
• c. leaving alone said surface with the applied coating composition until it cures.

A method of coating a structural material chosen from the group consisting of metal, wood, masonry, brick, porous ceramic building brick and concrete and having a wet or moist surface including a surface immersed under water, comprising the steps of:

• a. thoroughly mixing, to provide a non-aqueous coating composition:
• A. an epoxy resin consisting of a polyepoxide having a plurality of vic-epoxy groups and containing only members of the group consisting of carbon, hydrogen, oxygen and chlorine, and
• B. a stoichiometric amount of an amine curing agent which is substantially insoluble in water and not water-sensitive and chosen from the group consisting of
• 1. an amine of the formula ##STR12## where R.sub.1 is chosen from the group consisting of ether radicals of which one of the alkyl or alkylene radicals has at least eight carbon atoms, and
• 2. a condensation product of a small proportion of a polyepoxide having a plurality of vic-epoxy groups and containing only members of the group consisting of C, H, O, and Cl, and a large proportion of a fatty amine of the formula:
• ##STR13## where R.sub.2 is chosen from the group consisting of alkyl radicals having at least eight carbon atoms and ether radicals of which one of the alkyl or alkylene radicals has at least eight carbon atoms,
• b. applying said coating composition to said surface, and
• c. leaving alone said surface with the applied coating composition until it cures.
