<p><P>PROBLEM TO BE SOLVED: To easily and stably provide a beautiful resin-containing decorative aggregate layer such as a wall, a spandrel wall, a fence or a staircase rise, for which an aggregate full of decorativeness can be utilized, workability is substantially excellent compared to a conventional method upon the construction, and weatherability is excellent simultaneously. <P>SOLUTION: An elevation surface or a wall surface having a resin-containing decorative layer structure includes a base surface, a thixotropic aggregate adhesion layer on the base surface, and a decorative aggregate layer provided on the aggregate adhesion layer and formed of a mixture containing a decorative aggregate and a thixotropic resin binder. The thixotropic resin binder contains a resin and a thickening material, and the resin contains, as a main component, a one-component polyurethane resin whose viscosity at 23°C is in the range of 400 to 2,000 mPa s and viscosity at 10°C is 1,200 to 7,000 mPa s. Also, the thickening material is a hydrophilic treatment object of fumed silica, the additive amount of the thickening material is in the range of 3% to 12% to the resin by a mass ratio, and a thixotropic performance when the thickening material is added for 4% is in the range of 3.0 to 7.0. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
