Making a Brush-On Glove Mold Using Dragon Skin® and Casting a Faux Wood Reproduction
Dragon Skin® Q is a high performance platinum cure silicone rubber that can be mixed 1A:1B by weight or volume and cures at room temperature with negligible shrinkage to a Shore 10A. Cured Dragon Skin® is very soft, very strong and very “stretchy”. It will stretch many times its original size without tearing and will rebound to its original form without distortion.

This stretchiness makes Dragon Skin® Q ideal for creating one piece glove molds.  A Dragon Skin® mold can be turned completely inside out without risk of tearing.  This means castings can be removed without cutting the mold, leaving no visible flashing common with many mold configurations.

1 - The original is a carved wood model. In most cases when reproducing a wooden original, it is important to also reproduce the woodgrain.
 Gallery Image

2 - Gather all materials, including accessories, prior to beginning the mold making process.
 Gallery Image

3 - Begin by securing the original model to a melamine board using hot melt glue.
 Gallery Image

4 - Next, spray the original model with Ease Release® 200 release agent. This will aid in removing the cured silicone mold from the original.
 Gallery Image

5 - Measure out Part A of Dragon Skin® Q silicone rubber. It is important to use the fast set version (''Q'') when making a brush on mold. This will drastically speed up the mold making process.
 Gallery Image

6 - Measure out and equal volume of Part B.
 Gallery Image

7 - Dragon Skin® is translucent in its natural state. This can sometimes make it difficult to ensure thorough coverage over an original model. Adding a small amount of Silc-Pig® silicone pigment will eliminate this problem.
 Gallery Image

8 - A small amount of THI-VEX® II silicone thickening agent is added to the mixture. This will help the silicone stay on vertical surfaces.
 Gallery Image

9 - Combine all components and mix thoroughly. Continue mixing until there are no color striations present.
 Gallery Image

10 - Apply Dragon Skin® Q to the original model.
 Gallery Image

11 - The first layer of a brush-on mold should be thin. This will help eliminate any chance of bubble entrapment.
 Gallery Image

12 - Apply Dragon Skin® Q over the entire model and begin building a flange 3'' (8 cm) around the base of the model. Allow rubber to cure until tacky (approximately 45 minutes).
 Gallery Image

13 - Mix a second thickened batch of Dragon Skin® Q. Adding a different Silc-Pig® pigment to alternate layers will help ensure thorough coverage over the entire model.
 Gallery Image

14 - Apply a second coat of Dragon Skin® Q. The yellow Silc-Pig® contrasts well with the previous layer.
 Gallery Image

15 - Second layer can go on thicker than the first.
 Gallery Image

16 - Completely cover the model and continue building flange. Allow rubber to cure until tacky (approximately 45 minutes).
 Gallery Image

17 - Mix a third batch of Dragon Skin® Q silicone.
 Gallery Image

18 - Add additional THI-VEX® II thickening agent to this layer.
 Gallery Image

19 - Using much thicker material means the mold can be built up faster. Use a stick to trowel the thickened rubber over the previous layer.
 Gallery Image

20 - Cover entire model and continue building flange. Allow rubber to cure until tacky (approximately 45 minutes).
 Gallery Image

21 - Mix a final batch of Dragon Skin® Q with some THI-VEX® II added.
 Gallery Image

22 - Brush this batch over all other layers. This layer will further build thickness, but will also smooth out the surface of the mold, making application of a support shell easier.
 Gallery Image

23 - Completed Dragon Skin® Q brush-on mold. Ultimate mold thickness should be approximately 3/8'' (1 cm). Allow rubber mold to completely cure (approximately 75 minutes).
 Gallery Image

24 - Prepare the mold for application of the support shell by trimming back the flange to a straight edge around the entire mold.
 Gallery Image

25 - Gather materials used to create the support shell.
 Gallery Image

26 - This mold requires a two-piece support shell. Begin by planning out where the support shell will split to prevent mechanical lock. Draw a line over the high points of the model.
 Gallery Image

27 - Using water clay, create a shim along the line drawn in the previous step. This shim will act as a separation line between the two halves of the shell. Brush Smooth-On's Sonite® Wax over all surfaces Plasti-Paste® will come in contact with, including the base board.
 Gallery Image

28 - Smooth-On's Plasti-Paste® filled urethane plastic is designed for use as a support shell. It is mixed in a ratio of 1 Part A to 3 Parts B by volume.
 Gallery Image

29 - Mix and apply Plasti-Paste® over the rubber mold.
 Gallery Image

30 - Build Plasti-Paste® support shell to an ultimate thickness of 3/8'' (1 cm).
 Gallery Image

31 - After first half of Plasti-Paste® shell has fully cured (about 90 minutes), removed clay in preparation for application of second half.
 Gallery Image

32 - Plasti-Paste® will stick to itself and other surfaces vigorously. It is important to use a release agent to separate the two halves of the shell. Begin by applying Smooth-On's Sonite® Wax to any surface the fresh Plasti-Paste® will come in contact with.
 Gallery Image

33 - Follow the application of Sonite® Wax with a spray coat of Universal Mold Release®.
 Gallery Image

34 - Mix and apply a second batch of Plasti-Paste®.
 Gallery Image

35 - Build Plasti-Paste® support shell to an ultimate thickness of 3/8'' (1 cm).
 Gallery Image

36 - Allow Plasti-Paste® shell to full cure (approximately 90 minutes).
 Gallery Image

37 - Once the Plasti-Paste® has cured, the support shell can be removed.
 Gallery Image

38 - Before peeling back the rubber mold, apply some talc powder to the outside surface of the mold.
 Gallery Image

39 - The talc powder will make removing the Dragon Skin® mold easier by reducing friction on the surface of the rubber.
 Gallery Image

40 - Begin removing the Dragon Skin® by peeling it back from the base.
 Gallery Image

41 - Continue rolling the rubber mold over on itself. Dragon Skin® is soft and stretchy enough to be completely inverted, like a glove.
 Gallery Image

42 - The Dragon Skin® rubber will reflect perfect detail captured from the original piece. Because the silicone is so stretchy, there is no need to cut the mold in order to remove the original.
 Gallery Image

43 - Re-seat the Dragon Skin® mold into the Plasti-Paste® support shell. Rubber bands are used to bind the two halves of the shell together.
 Gallery Image

44 - Invert the mold and place it into a bucket. Once the mold is level, the casting process can begin.
 Gallery Image

45 - When reproducing woodgrain, it is important to use the appropriate combination of resin and filler. Smooth-On's Ure-fil® 5 is combined with Smooth-Cast® 300 to create a woodgrain finish. The proper mix ratio is 1 Part A to 1 Part B to 1 Part filler by volume.
 Gallery Image

46 - Combine all elements. Adding SO-Strong® Brown pigment will result in a casting closer in color to the original. Mix all elements thoroughly until no color striations are present.
 Gallery Image

47 - Once thoroughly mixed, pour the resin/filler mixture slowly into the mold.
 Gallery Image

48 - Once the Smooth-Cast® resin has cured (about 10 minutes) the Dragon Skin® silicone mold can be removed from the casting.
 Gallery Image

49 - Cured casting is a dull tan color, but the woodgrain is still present in the piece. It simply needs to be highlighted.
 Gallery Image

50 - In this case, black shoe polished is brushed into the surface of the piece.
 Gallery Image

51 - Allow the shoe polish to sit for a short period, then use a paper towel to wipe off excess. Shoe polish will remain in details and deeper areas of the casting.
 Gallery Image

52 - Following a spray with clear acrylic lacquer, the finished pieced is displayed alongside the original. The woodgrain has been reproduced to perfection and casting looks just like real wood!
