ARREDOFIX
HIGH PERFORMANCE READY TO USE PROFESSIONAL PASTE ADHESIVE FOR
THE RECONSTRUCTED STONE AND BRICK LAYING
bianco
DESCRIPTION:
ARREDOFIX is ready to use paste adhesive, composed of synthetic resins in watery
dispersion, selected mineral fillers and special additives. ARREDOFIX is an easily
applicable viscous paste. It is characterized by extended open time and thixotropic
qualities that allow vertical applications without stone slip. ARREDOFIX has good water
resistance that allows its use also in a slightly humid environment and excellent elasticity
that allows its use onto flexible and deformable substrates. It conforms to regulations EN
12004 – Class D2TE. (D) dispersion adhesive (2) improved adherence – (T) no vertical
slip – (E) extended open time.
USE:
ARREDOFIX is used for reconstructed stone and bricks laying at wall onto any kind of
absorbent substrate like cement plaster, prefabricated concrete panels, asbestos cement,
gypsum plaster, plasterboard and onto wooden panels on condition that they are water
resistant, etc. For indoors and outdoors.
PREPARATION OF SUBSTRATE:
the substrates must be plain, solid, and free from inconsistent parts, dust, grease and old
varnishes. New cement screeds must be cured (approximately one week per cm of thickness);
otherwise ARREDOFIX will not set regularly. ARREDOFIX can be directly applied onto
gypsum or similar substrates, without prior application of insulating primers, on condition
that they are dry, solid and consistent.
APPLICATION:
apply the first layer of adhesive very thin with a smooth part of spatula to guarantee a good
adhesion and to adjust the water absorption level, then apply the adhesive with a suitable
toothed spatula (4-6 mm). Apply a thin layer of adhesive at stone reverse (double spread
method) and position each stone pressing it into place to embed it.
Make sure the adhesive has not formed a superficial film. If this will happen, run the toothed
edge of the spatula over it again. Grouting can be executed after 24 hours after laying.
CONSUMPTION:
3 - 4 kg/m 2 , according to the kind of substrate.
PACKAGING:
ARREDOFIX is packed in plastic buckets of 8 kg and 20 kg. Store the product in a dry
place, sheltered from frost, in the original well-closed packaging. In these conditions its
shelf life is of 12 months.
WARNINGS:
do never apply ARREDOFIX onto metal surfaces nor onto non absorbent ones. It can be
used for big size stone laying. Protect the laid substrates from rain for at least two days
from the laying. Final hardening: after 7-14 days, according to the substrate absorption.
Adverse weather conditions may both shorten or extend the setting and hardening time. The
tools used for the application can be washed with water when the adhesive is fresh and with
trichloroethylene once hardened.

SPECIFICATIONS:
The laying of indoor and outdoor reconstructed stone walls should be done with ready to use
paste adhesive with high performance, no vertical slip and extended open time, classified
as D2TE by the standard EN 12004 (such as ARREDOFIX of COLMEF brand PIETRE
D’ARREDO), suitable for the laying onto traditional substrates, onto gypsum, plasterboard
without prior application of insulating primer.
