Abstract
A floral base is made by hot wire cutting a foam of expanded polystyrene beads, thereby forming a smooth skin over the cells at the cut surface; differentially wire brushing the hot wire cut surface, lightly in some areas so that the wires only slice the surface skin and more deeply in adjacent areas so that the wires gouge out beads to form cavities and roughly parallel channels; then coating the surface with a latex paint. The resultant material surprisingly simulates the appearance of rough weathered lumber.
Claims10
The method of simulating the appearance of rough weathered lumber with a foam material, comprising,
- providing a rigid, closed cell foam of cohered, expanded polystyrene beads,
- cutting said foam to form a desired shape therefrom,
- wire brushing the surface of said shape to form spaced, elongated, generally parallel but irregular grooves and cavities on it while varying the brushing action on different areas of said surface such that at some regions thereof the beads at the surface are merely cut by the wires of the brush while at other regions the wires gouge so deeply as to remove beads as irregular chunks and thereby form said cavities and grooves,
- removing the loose abraded material,
- and applying a latex paint over the surface so prepared to seal and color the same.
A foam material which simulates weathered rough lumber,
- said material being a rigid, closed cell foam of cohered, generally spherical expanded polystyrene beads and having a cut major surface,
- the cut beads at said major surfaces having a flat skin thereover,
- a series of generally parallel irregular grooves and cavities of differing width and depths formed in said major surface,
- said grooves and cavities being defined by removal of groups of entire beads,
- said major surface also having thereon a plurality of much narrower, elongated shallow slit-like cuts,
- said surface being coated with a latex paint.
