Making Tree Bark Texture Panels Using Plasti-Paste® II
Over the years, people have attempted to use Plasti-Paste® as an art or fabrication material assuming that the cured plastic can be painted, only to be disappointed to find that it can not. The new Plasti-Paste® II formulation differs from the current formulation in 2 major ways: 1. Cured plastic can be painted (original Plasti-Paste® can not) 2. It is harder, more rigid with better heat resistance (when post cured).
The New Mix Ratio is 1A: 2B by volume (62A:100B by weight). The pot life is 10 minutes at room temperature depending on mass. Handling time is about 90 minutes at room temperature depending on mass. Full cure; 24 hours at room temperature. Cure time can be accelerated by applying heat.
Mixed material holds a vertical surface without sagging and cures to a strong, durable and lightweight plastic. Liquid material can be pigmented with So-Strong® color tints.
This plastic can be used for creating themed environments or special effects, used as a “mother mold” material to reinforce rubber molds and a variety of other applications.
Case Study:
One of our customers had to reproduce segments of tree-bark texture for a children's museum. They had over 40 gang molds of tree bark texture and utilized the new Plasti-Paste® II formulation to create the castings which were then painted with wood stain. Blended turf and glue were then spot added for a moss effect. Hundreds of panels were cast for this display which will be installed in February.
1 - Smooth-Sil® 920 silicone molds are prepared.
2 - The NEW Plasti-Paste® II is mixed thoroughly.
3 - Plasti-Paste® II is troweled into the mold.
4 - The material is pushed into the detail as the surface is leveled off.
5 - After curing, Plasti-Paste® II is demolded and displays great detail.
6 - Two shades of stain are applied for realism. A dark basecoat is used first.
7 - A light stain is applied to the raised areas of the bark.
8 - Blended Turf, is added to simulate moss growth on top of the bark.
9 - The NEW Plasti-Paste® II provides a very versatile and durable material for themed environments.
