Achieving A Woodgrain Finish using Smooth-Cast® Resin

Achieving A Woodgrain Finish using Smooth-Cast® Resin

A woodgrain finish can be attained through the process of mixing Smooth-Cast® 320 with various colors of So-Strong® urethane tints and Ure-Fil® 5. Different wood finished such as oak, pine, maple and mahogany can be achieved by varying the amount of So-Strong® tint and/or Ure-Fil® 5, then staining and clear-coating. Casting wood pieces in urethane is fast, realistic and less expensive than hand carving. NOTE: In order to achieve a woodgrain finish or effect, the original model must have a wood grain pattern.

1 - Original wood carving is sealed with SuperSeal® then glued to a base board.	2 - Walls are constructed around the object to form a mold box. Minimum of ½ inch clearance is required.	3 - Dragon Skin® silicone rubber is mixed, vacuumed and poured into the mold box completely covering the object with ½ inch of rubber.
4 - Allow the Dragon Skin® silicone mold rubber to cure a minimum of 5 hours.	5 - The mold walls and Dragon Skin® mold are removed from the original carving.	6 - The Dragon Skin® silicone rubber captured the fine texture and detail of the woodgrain.
7 - Smooth-Cast® 320 casting resin, Ure-Fil® 5, So-Strong® Brown tint and brown shoe polish are assembled along with mixing containers and supplies before beginning.	8 - It is important that the Ure-Fil® 5 is 100% moisture free prior to use. Recommended: Bake Ure-Fil® 5 at 150°F / 60°C for 30 minutes to eliminate any residual moisture. Allow the Ure-Fil® 5 to cool to room temperature before using.	9 - The Smooth-Cast® 320 Part A, Part B and Ure-Fil® 5 are measured in equal amounts by volume.
10 - Smooth-Cast® 320 Part B is poured into a mixing container.	11 - The Ure-Fil® 5 is added to the Smooth-Cast® 320 Part B.	12 - Smooth-Cast® 320 Part B and Ure-Fil® 5 are thoroughly mixed.
13 - Once the Smooth-Cast® 320 Part B and Ure-Fil® 5 are thoroughly mixed to a smooth consistency, a few drops of So-Strong® Brown tint are added.	14 - Smooth-Cast® 320 Part A is added and thoroughly mixed. Scrape the sides and bottom of the container several times while mixing.	15 - Once the liquid is mixed to a consistent color, slowly pour mixture into one spot of the mold. Allow the liquid to flow through the mold until the mold cavity is completely full.
16 - Allow the casting to cure for a minimum of 30 minutes.	17 - The cured casting is removed from the Dragon Skin® silicone rubber mold.	18 - Brown shoe polish is brushed onto the surface of the casting to bring out the woodgrain. A variety of wood stains can also be used.
19 - When finished, the reproduction shows perfect woodgrain patern.	20 - Original wood carving on left, finished casting on the right. A perfect reproduction.
