Using Goop

Written by Glenn. Posted in Scenery

goop-exbn-09-smRecently a demonstration module was completed for the Hurstbridge Model Railway exhibition. The module shows various stages of construction using foam cut, glued and shaped. Next a layer of goop (see below) was added followed by painting to represent bare clay.

Goop was also used to start the creek running under the bridge on the shelf layout. Cardboard strips were hot glued in place. Next a layer of goop without the Vermiculite was used.

Goop Recipe

This recipe came from Mark Laidlay and I have used it successfully.

Ingredients

Ingredient Proportion Suggested Brand Source

Paper Mache Mix

1 cup

Sharmrock Craft

Art/Craft supply

Vermiculite

1 cup

Brunnings

Nursery or larger hardware chains

Disenfectant/rubbing alcohol

1 capful

Lysol 

Chemist/super market

Latex Paint

1 cup

Any brand, 

your ground colour

Hardware or paint shop
White Glue 1/2 cup Any brand Hardware
Disposable Wipes as needed Chux or generic brand  
Water as needed    

 

Method

  1. Ensure the area to be done has been shaped roughly to what is required and that the area is free of dust, oil and other contaminents.
  2. Measure and mix the ingredients together leaving the water to last.
  3. Add water whilst mixing. The mixture needs to be the consistency similar to peanut butter.
  4. Mix thoroughly until the mixture is homogenous.
  5. Cut the wipes to size.
  6. Dip each wipe in the mixture ensuring it is covered completely. Allow the excess liquid to drain off to avoid messing up your layout.
  7. Apply each wipe in turn to the formwork smoothing down each one.

After a few days the structure should be dry, firm but not too rigid.

A second layer can be applied to smooth out the edges of the wipes which may be visible through the first coat of goop.

Goop landscaping in action

Mark used a layer of chux dipped in a thin version without the Vermiculite and with double white glue for the first layer then full strength goop for the next layer.  In subsequent weeks we will add a bit of ground cover then electro-static grass.
