DESCRIPTION:
Artificially reconstructed stone and bricks are the exact reproduction of natural stone and cotto
bricks. They are manufactured with special binders, natural inert, extremely UV rays resistant
coloured pigments and special additives conferring high resistance against atmospheric agents.
Aesthetic effect of Pietre d’Arredo is completely similar to the natural stone. They are lightweight,
resistant, breathable, frost-proof, water-repellent and suitable for indoor and outdoor projects.
USE:
They are suitable for indoor and outdoor decoration of walls, fences, columns, fireplaces, etc.
INSTALLATION:
In order to estimate the amount of stones needed calculate the area to be covered, the lineal
meters of outside corner areas to be covered and the number of corner stones necessary. However
some extra quantity is always needed for best fitting including cutting and trimming.
PREPARATION OF SUBSTRATE:
All the areas to be covered should be allowed to cure, must be plane, resistant, free from
inconsistent parts, dust and grease substances.
Cement substrates: must be allowed to cure for 28 days at least considering the concrete
shrinkage during that phase.
Very absorbent, friable or dusting substrates: must be treated with consolidating primer
such as PRIMER A 18*.
Cellular concrete blocks: must be treated with PRIMER A 18* and subsequently reinforced
with ARMOFLEX 130 and smoothed with ISOTHERM F 1* or ARREDOCOLLA.
Masonry subject to rising damp: see INNOVATION SYSTEMS
Thermal insulation panels: see INNOVATION SYSTEMS
Gypsum substrates: must be dry, hardened enough free from dust and preliminarily treated
with resins such as PRIMER A 16*.
Plasterboard substrates: must be stable as much as possible.
Varnished substrates: check if the varnish or paint are well anchored to the substrate, then
clean it carefully. In case of doubts, apply metal lath Ø 1 mm (mesh 10x10 mm) and fix it
mechanically every 20 cm.
Metal surfaces: must be grease free. We recommend the surface to be cleaned with a rug
soaked with diluent and to apply the metal lath as described before.
For further information or particular use, contact our Technical Assistance Service.
PREPARATION OF ADHESIVE: The most suitable adhesive for the stone laying is
ARREDOCOLLA with no vertical slip, and thus for ease of application, guarantee of lasting
and reduction of superficial efflorescence at the stone surface. Add ARREDOCOLLA bag
of 25 kg into a container of 6,5-7 litres of clean water and mix until a uniform lump free
consistency is achieved. Keep the obtained mix for some minutes and then remix before
application. In case of synthetic resin based adhesive choice such as ARREDOFIX, any
mixing is necessary as it is ready for use paste. In case of polyurethane adhesive such as
POXYCOL*(A+B) use, mix the component A with the component B until you obtain a
homogeneous mixture that can be applied with spatula like common adhesives.
Important: Before application we reccomend to consult the appropriate Technical Data Sheet.
STONE AND BRICK INSTALLATION:
Start the application from the corners first, alternating the longer and shorter returns on
corner pieces in order to create a natural appearance of the covering. It’s easier to start from
bottom up, it is also possible to work from up to down. Do never lay long sides vertically.
Being the stone coloured manually, the difference of tonality can appear between one box
and another. To avoid these differences open more boxes at the same time and choose the
single stone pieces arranging them so that they fit and look nice next to each other.
Apply the adhesive at the substrate with a suitable spatula spreading it with a trowel also at
stone reverse. Apply sufficient pressure onto the stone in order to ensure good contact with
the adhesive; leave a joint of at least 1-1,5 cm between the bricks and of 2-2,5 cm between
the stones. Protect the covering from rain and from direct sun rays until the adhesive is
completely hardened.
STONE GROUTING:
Grout the stones and bricks with a suitable fibres-reinforced mortar with low water absorption:
ARREDOSTUCCO. It’s available in various tonalities to match with a kind of stone chosen to
obtain a pleasant aesthetic effect (see the table below). After having mixed the product with
water, apply the mixture directly into the grouts between the stones using a suitable grout
bag. Once the mortar looses plasticity and is firm enough, remove its excess with a suitable
tool or trowel and finish it with a brush. In case stone or bricks get dirty, allow the mortar
to dry thoroughly, and then scrub with a dry brush. Do not use a damp sponge. Protect the
covering from rain and from direct sun rays until the adhesive is completely hardened.
