PVA glue is an everyday household glue or craft glue, often used by children. This white glue dries to a transparent finish, which makes it ideal for creating ponds, oceans and rivers for hobby terrains, such as for train modelling or school projects. Mixing the glue with different materials will create different textures that can make the water almost appear as if it is moving like real water. Experiment with different additives and textures to get the water look you want.
Paint the inside of the water base to look like the base of a pond. You can use browns, blacks, blues or greens to make the base look like your specific type of water. For dirty water or rivers, use browns and blacks. For clean water, use blues. For swamps use a green base. Allow the paint to dry overnight.
Mix three parts glue and one part water together in a small bowl. Add a few drops of blue or green food colouring to make clean water, or you can leave the mixture without food colouring for a more transparent pond or to make foaming water.
Pour the glue into the water base to a thickness of about 1.3 cm (1/2 inch). Allow the glue to dry for 72 hours. Continue adding 1.3 cm (1/2 inch) layers of glue until the depression is full. When the glue is half dry, speckle the top of the glue with a paintbrush to create texture on the water.
Mix one part glue with one part plaster powder. Mix the two materials together until the powder dissolves.
Paint the mixture onto the water where you want to add texture, such as foaming around rocks, waves or at the base of waterfalls.
Allow the mixture to dry until nearly hard. Speckle the surface of the foam with a paint brush. Allow the mixture to dry completely. Repeat this process two more times to create depth in the foam water.
