ArtRoc (Modroc) is a plaster impregnated cloth strips which is used for modelling. ArtRoc is a wonderful construction material that can be used on its own, or combined with armature wire, box construction, moulds, chicken wire or rolled up newspaper. ArtRoc dries hard, dries quickly, it is easy to manipulate and form. Box of 10kg. 48 rolls approx. 5m each in length.

To use: Using Modroc Sheers cut ArtRoc cloth into smaller strips. ArtRoc requires a small amount of water to activate; dip strips into water and then gently squeeze out excess water. Layer over model. The finished dry construction can be painted, drawn on or glossed, while embellishments may be glued on.

NB. Holes and staples need to be made during construction.

Care instructions: DO NOT throw the ArtRoc water down domestic sinks as the plaster residue will block drains; throw the water outside into a garden. Be careful to have a well-ventilated area. Encourage the children not to shake the ArtRoc, as excessive plaster powder will be released into the air. This is not good for breathing or for cleaning.

Mask Making: You can make approximately 60 full faced children’s masks from a 10kg bag of Modroc.
Drying Time: Drying time will vary depending on room temperature and how many layers of ArtRock have been used. It will take approximately 6 – 8 hours for three layers of ArtRock to dry in a moderate room temperature of around 20°C.
Reworking a Form: Although ArtRock can be softened with water after it has dried, it is not recommended and can damage the plasters ability to harden again. It is possible however to apply wet ArtRock over dry allowing a project to be worked on indefinitely.

Step 1: Create an armature from polystyrene shapes, newspaper, wire, cardboard, masking tape, etc.

Step 2: Use Modroc shears to cut strips of Modroc suitable for the size of the artwork.

Step 3: Add a squirt of PVA to a container of water.

Step 4: Dip single Modroc strips into water/PVA mixture and squeeze excess water out of the Modroc.

Step 5: Wrap Modroc over your armature making sure to overlap strips and vary directions to give strength.

Step 6: Smooth the Modroc with fingers to blend the plaster and hide the edges of the bandages.

Sculptural Forms: Experiment by creating Modroc ‘sheets’ which can then be impregnated with objects, printed, coloured and sewn. Explore surface textures, form and design.
