RECOMMENDATIONS FOR INSTALLATION
FITTING TECHNIQUE
Joints:
These are the separations left between the tiles for aesthetic or functional
reasons (dimensional deviations). The fitting is considered to be with a
joint when the separation between tiles is equal to or over 3 mm, and
without joints when this is under 3 mm (on deformable supports or any
subject to possible movements the use of a joint is essential).
In the event of working without joints the minimum separation advisable
is 1,5 mm due to the fact that smaller separations do not prevent contact
between tiles.
There are various types of joints in a site:
This documents considers the following types of joint-filling material:
· Portland cement grout: JC
This is used in interior spaces with no additional stress. it is not advised
in hygienic or frequently cleaned zones.
· Joint mortar: J1
Ready-made mortars for joints consisting of cement, sand, synthetic
resins and additives which give a greater water retention capacity. These
can contain pigments. Available for fine and broad joints.
Used in joint-filling on indoor wall tiles and both indoor and outdoor
paving. Compatible with all kinds of tiles (not recommended in wall tiles
with deformable supports, facades, areas with heavy traffic, heated floor
tiling or paving, places frequently cleaned with aggressive products and
ones for health and foodstuff use. The maker indicates the quantity of
water to be used for mixing.
· Deformable joint mortar: J2
Differentiated from the previous one through containing latex (can also
be added to the mixing water). This additive increases the flexibility,
improves the resistance to humidity and to abrasions as well as increasing
adhesion in materials that do not absorb very much.

A. Structual Joints:
These are designed to absorb movements in the building and must
always be respected. They can be covered with adequate profiles and
filled with the indicated materials.
B. Perimeter Joints:
All joints where the wall meets the floor. The minimum width will be
8 mm and must be empty or filled with a deformable material. They can
be concealed with the skirting board or the wall tile.
C. Settin Joints:
These are the spaces left between tiles. The setting will be considered to
have a joint when the space between each tile is greater than or equal to
3 mm. For spaces of less than 3 mm, there is considered to be no joint.
There should always be a minimum gap of at least 1,5 mm.
Recommended for use on facades, tiling deformable supports (such
as wood) pavings with heavy traffic and areas with a high degree of
humidity. Not recommended in places subject to frequent cleaning with
aggressive products as well as areas for foodstuff and sanitary use.
· Epoxy mortar: JR
Consists of synthetic resins and an organic hardener (can also contain
minerals) This product withstands chemical products and provides
bacteriological resistance as well as high adherence. Stands up very well
to humidity and abrasion.
Recommended for use in areas with aseptic requirements, chemical
resistance and humidity and abrasion.
EXECUTION AND SEALING:
We recommended partially filling the fitting joints with strips of
compressible material (rubber and cellular plastics, as well as sheets of
cork or fibres for calking) before filling these completely.
This material must be recovered after compression. This should be
enough to support the joint-filling material and prevent the joint from
ejecting this when it tightens up.
The compressible material should not adhere to the joint-filling material
(if this were to occur cover with isolating tape). These tapes should allow
the application of a suitable amount of joint-filling material, to a depth
of at least 6 mm.
