Back wall
Model 2
Material: styrofoam, flex tile adhesive, polyurethane foam (PU-foam) , silicone / polysiloxane, acrylic paint
Styrofoam pieces
are attached for slabs and structure . This goes with Silicon (without
fungicides and most solvent-free) or even Styrofoam glue . For large
platforms
even toothpicks or skewers can provide more stability.
For a more
natural
form , it is recommended as the pieces edit with a knife
Even with a heat
gun
can be wonderful shapes create (Warning , best outdoors or in well
ventilated
rooms )
With PU foam may
well
transitions and other natural structures are introduced
Below about 3
layers
Flex - flow adhesives are applied . Important: Each layer must be dry
before
applying the next layer .
The last layer tile adhesive is mixed with very thin and mixed with paint
Last step:
For a sealed but pretty rough surface:
The first layer of glue (for example wood glue 3D oder 4D) is applied pure and wait until dry . In addition, a further layer of glue which is mixed with sand . Another sand can be pressed into the wet layer.

So erhält man eine versiegelte aber schön raue Oberfläche
The best results
can
be build from styrofoam and flex tile adhesive. This really is
recommended to
the flexibility of the flex adhesive because such cracks by the
expansion of
the terrarium can be avoided better.
It is important
that
all materials are harmless for the animals. This means a high scratch
resistance and heat resistance and UV resistance without outgassing or
variation are important here. Also should always be preferred
solvent-free
substances.
Some components,
such
as polyurethane foam or epoxy resins are toxic in non-dried state, but
completely dry out there is no more danger from. PU foam should but of
course
never happen freely in captivity and are as the design of the structure
under
the tile adhesive.
The color of the
wall
should be kept as bright as possible, because dark colors swallow a lot
of
light, and thus lost a lot of brightness.
A complete seal
of the
rear wall is not absolutely necessary in dry terrariums. It is often
sufficient
if the timber walls, and especially the bottom surface to be sealed.
