Setting out your work
Your early preparation is important if you want to ensure that you make the most of your Modroc bandage. Remember, that once your Modroc is wet or damp, it only takes a few moments for it to start to harden, and then a further few minutes for it to be too hard to work. Speed of working is important, so plan what you are going to do before starting.
Storage
Each of the bandages that we sell has been individually sealed, and the expected shelf life can be years. Only remove  the product from the packaging when you require it. Any contamination with water, or even damp, will make it un-useable.
How much to soak
We suggest that you only soak what you know you are going to use. Cut the roll into short lengths as required. Remember you will need at least 3 layers of mod-roc, so prepare plenty of strips. Change the water if it begins to get cloudy or creamy, as this may cause delaminating as the material dries.
Soaking
Soak the bandage in tepid, not hot, water for about 5 seconds. The hotter the water, the faster the bandage will set. Remove the bandage as soon as bubbles stop rising to the surface of the water.

It is possible to add 1 part PVA glue to 2 parts water when soaking a bandage. This has several benefits. The first is that it aids the bandage to stick to your chosen framework. The second is that several layers of bandages stick together better, and the third is that it dries much harder and helps prevent cracking and flaking at a later stage.
Squeezing
Plaster of Paris is safe to handle both wet and dry. Gently squeeze out excess water, but do not squeeze until it is dry.
Wrapping and layering
Immediately after squeezing cover the area to be covered. A few layers may be required to achieve total coverage. When applying a further layer, be sure to press the top layer onto the lower layer to prevent air pockets developing, and try not to let the lower layer dry before adding the top layer. Where possible always stagger joints.
Setting
The normal setting time for this type of bandage is between 2 and 5 minutes. It is possible to shorten the drying time by applying heat, but care should be taken to ensure the bandage does not get too hot. To lengthen the drying time cold water could be used to soak the bandage.
Painting
Once fully dry it is possible to paint the bandage to seal the surface using any water based paint. Once dry you can add your flock or covering as required.
