Jointing natural stone - a small job with
big consequences
Looking in the current literature on
"Natural Stone" for information on joints
is usually a thankless task, even though
correct joint work is the final step in ensuring
that the hard work that goes into in
tiling or paving yields high quality results.
Incorrectly formed joints or joints made with the wrong materials not only render
the work worthless, but can also result in
costs that are impossible to estimate
arising from complaints, cleaning or even
damage. |
Ugly "grease stains" on
the edges caused by the
wrong sealants which
release plasticizer into
the stone. |
|
Other possible consequences are legal
disputes and the damage they do to the
corporate image, and the loss of future
orders.
A company that saves on sealant
is not only endangering its good reputation
but is also running the risk of serious
economic consequences.
As a leading manufacturer of sealants and
adhesives, OTTO has created this jointing
guide for builders and designers.
It is
intended as a guide to possible "stumbling
blocks" in jointing natural stone and to
help avoid making expensive mistakes in
the choice of joint sealants. It also serves
to make buyers of building services more
aware of the problems and to highlight the
importance of expecting high standards.

Extreme exposure on facades
With temperatures possibly ranging from
-40 to +100 °C, exhaust fumes, precipitation
and constant exposure to UV light, sealants
for façades need to be of a very high
quality indeed.
To stop water or emissions penetrating
behind the stone, the sealant must offer
permanent resistance to these extreme
conditions and absorb any movement in
the façade caused by fluctuations in the
temperature.
With its outstanding chemical and physical
properties, OTTOSEAL® S 70 meets these
challenges superbly. Its high resistance to
UV and ageing make it a natural stone
sealant which will maintain the value of a
façade over many decades and help avoid
costly maintenance and renovation work.
The OTTO guarantee against edge staining
gives additional assurance. |
The sealant is exposed
to UV radiation, precipitation,
chemical emissions
and fluctuations
in temperature and
subjected to stress in
all directions; it must
withstand all of these
without loosing the
ability to function.

Using natural stone in wet areas or under
water such as bathrooms or swimming
pools requires a sealant with special
properties.
OTTOSEAL® S 70 is also the
optimum solution for this range of
applications. As well being suitable for
use with natural stone, OTTOSEAL® S70
also includes a fungicide which prevents
the growth of mould.
Using OTTOSEAL® S 70 to seal joints in
natural stone in permanently wet areas
ensures outstanding performance; it is
neutral in reaction and withstands attack
from cleaning agents and disinfectants
(e.g. chlorine) and mechanical damage
from cleaning. |
Joints in bathrooms and
other wet areas should
be provided with a
fungicidal agent and also withstand damage from
cleaning and bathers.
