![]() ![]() ![]() Adhered Stone veneer secured and supported by adhesion of an approved bonding material over an approved backing. Active solids are usually measured as a weight percent of the total. Active Solids Ingredients of a coating composition which are deposited following co-reaction or reaction with the substrate. They can be carried in a water or solvent solution and they are film-forming materials. Acrylics Resins resulting from the polymerization of derivatives of acrylic acids including esters of acrylic acid, methacrylic acid, acrylonitrite, and their copolymers. Acrylics resins vary from hard brittle solids, to fibrous elastomeric structures to viscous liquids, depending on the monomer used and the method of polymerization. The acrylic resins come from the polymerization of derivatives of acrylic acids, including esters of acrylic acid, methacrylic acid, acrylonitrite, and their copolymers. Acrylic Emulsions Clear water-based repellents which form a film. Accelerator A material used to speed the setting of mortar, epoxy, and polyester resins. Abutment The supporting wall or pier that receives the thrust of an arch a solid stone springer at the lowest point of an arch, vault or beam. The weight of water a brick unit absorbs, when immersed in either cold or boiling water for a stated length of time, expressed as a percentage of weight of the dry unit. The process by which a liquid is taken into (soaked up by) another substance and held there. Absorption is the percentage of moisture absorption by weight. Absorption A test method for stone from the American Society of Testing and Materials ( ASTM). Abrasive Hardness (Ha) Refers to the wearing qualities of stone for floors, stair treads and similar uses subjected to abrasion by foot traffic. Abrasive Finish A flat non-reflective surface finish. Abrasion Resistance The property of a surface by which it resists being worn away as a result of friction. Abate To cut away so as to leave parts in relief. A A-frame A wooden or metal rack constructed in the shape of an “A” on which large stone slabs are shipped and stored. ![]()
