Creating exciting naturalistic habitats with living plants has never been easier using the step by step products available from Peregrine. Simply create a basic structure with polystyrene, celcon block or expanding foam. Then create a natural looking surface by applying texturing compound and modeling to look like rocks or wood. Finally waterproof it with sealing resin, colored to your choice. The resin can be left bare or have bark, coconut fiber or sand pressed into it to make a rough, naturalistic surface that allows moss and plants to grow up it. This powdered modeling compound is used for the second stage. The power is mixed with water to make a paste and then spread over the basic structure to make a textured, realistic base ready for sealing.
