the background is going to be polystyrene then coated in a grout sand mix and possibly painted.
heaps of people have made their own backgrounds someone must know.
i need to coat the sand mortar mix in a sealent to make it easier to clean and to stop my beardie picking at the sand.
i read some where that pondtite or something was used??
woukd like to hear from some one who has made one and is happy with it |
