Information on working and processing
1. Shipment
/ Storage
GRAMA
BLEND® must always be shipped and stored either
standing upright or
stone
surface on top and with intermediate layers inserted for
protection.
GRAMA
BLEND® must be stored in interior depots.
GRAMA
BLEND® should always be stored, mounted or
processed at normal
room
temperature of 20 – 23oC and a substratum
temperature not below 10oC.
2. Cutting
a) Dry: The
cutting of minor adjustments or cut-outs can be done by
dry-cutting
process using
a flex or saw on site and diamond equipped tools.
Attention –
sense of rotation: Always process material with the stone
layer side
up to avoid
breakage.
b) Wet: Ideal
wet cutting on a suitable circular saw with diamond equipped
tools.
3. Mounting
a)
Gluing
2-component glues, such as "PCI-Collastic", “Sikaflex“,
“Terokal 723“ are
suitable.
Absorbent substructures may have to be prepared by applying
a primer. For
This
follow the manufacturer’s instructions.
b)
Velcro or adhesive tape as used in industry
c) Blind
rivets in 4 – 8 mmØ
Can
be done with a manual or electric riveter.
d)
Screw-fastening
-
screw-fastened to back wall
-
threaded bolts welded on to substructure (several hanging
systems
available). Threaded bolts only serve as means of fastening
/ positioning.
Additional gluing is necessary.
4.
Processing
a)
Drilling can be carried out with diamond-equipped trepanning
tools.
b)
Chamfers can be polished with an angle grinder, using
abrasive papers of
varying grain-size. By dry-cutting a good polish cannot be
achieved with
every kind of stone.
c)
Pointing can be done with:
-
rubber seal
-
silicone compatible with natural stone
-
Rigamuls (special pointing mortar)
-
cover moulding (plastic, brass etc.)
In
bathrooms, toilets and showers GRAMA BLEND® Alu-edge
should always be
Sealed
against corrosion, damp etc., with a suitable filling
material, such as
Akemi.
5. Putting
up accessories
- When GRAMA
BLEND® panels have been glued all over: drill
through the
panel and dowel (as on tiled wall). Accessories must be
fastened to the
existing substructure. Any forces caused (such as pressure
or bending) must
carried by the substructure or the backing.
- With a
superimposed fastening device, putting-up is done through
the panel
on
to the carrying profile.
6.
Substructures
All
substructures must be firm (statically able to withstand
loading and abrasion),
level
and suitable for gluing:
-
plaster carton panels
- plywood
panels
- smooth
cement facing
- tiles
- cement or
asphalt floor
