Faced building unit

A building unit comprising:

• a concrete block;
• an adhesive coating applied over a surface of said concrete block;
• a facing composition applied over said coated surface having about twenty-five (25) parts by volume of a dry mixture in proportions of:
• one part by volume portland cement;
• and two parts by volume of sand;
• about four (4) parts by volume aqueous wetting agent to provide a composition having the consistency of putty when mixed with said cement and said sand, said wetting agent including:
• an aqueous emulsion of 12.5 percent to 37.5 percent by volume of polymer resin solids derived from polymerizable vinyl compounds;
• said composition, when cured, having in the range of 1.96 to 5.66 percent by volume of resin solids retained therein.

A method of making a concrete block having a cementitious facing composition comprising the steps of:

• coating an open form with a non-adhesive composition;
• surrounding a concrete building block with the open form so as to leave an exterior surface of said block exposed, said form having an upstanding lip surrounding said block of a height equal to the thickness of said facing;
• coating said exterior surface with an adhesive;
• preparing a cementitious facing composition by mixing about twenty-five (25) parts by volume of a dry mixture including:
• one part by volume dry cement and,
• two parts by volume dry sand;
• preparing about four (4) parts by volume aqueous wetting agent for said dry mixture including 12.5 percent to 37.5 percent by volume polyvinyl acetate solids
• mixing said dry mixture of cement and sand with said wetting agent, and to leave in the range of 1.96 to 5.66 percent by volume polyvinyl acetate resin solids in the cured facing composition;
• applying said wet cementitious facing composition over said adhesive;
• removing said form from said block;
• allowing said facing composition to cure and dry to form a concrete block with its own cementitious facing.
