Preparation of the Surface
Every surface must be compact, smooth, loadbearing,
dry, clean and without any film (grease,
dust, etc.) which would reduce adhesiveness.
Remove old “loose” plaster, peeling paints and
other dirt. Minor uneven spots and cavities may
be repaired with TO-KS or universal TO-KU adhesive.
Repairs of the surface should be complete at
least 1 day before the EPS boards are affixed.
Implementation
- Before application, the temperature of the can and its content must be between +5°C and +35°C;
- Shake the can vigorously for about 30 seconds.
Additionally, shake from time to time during
application;
- Screw the applicator gun firmly onto the valve;
- Press the trigger and adjust the adhesive
quantity;
- Moisten the surfaces on which the adhesive is
to be applied but do not make them wet;
- Do not unscrew the gun before the can is
completely empty;
- Clean the applicator gun with special cleaners,
e.g. DOW Great Stuff Pro.
In thermal insulation systems, apply TO-KPS
polyurethane adhesive on a board in a strip of
approx. 3 cm circumferentially at a distance of
approx. 2 cm from the board edge, and additionally
one strip along the middle of the board in parallel
to the longer sides or in a M-shaped strip.
Immediately after applying the adhesive (within 3
minutes), affix the EPS board onto the wall, press
and adjust it with the use of a long batten. As a
result, the adhesive should cover at least 40% of
the board’s surface. The boards should fit tightly
one to another. The subsequent rows should be
off-set in relation to the previous ones so that the
board joints are in a staggered arrangement. Any
gaps may subsequently be filled with TO-KPS
polyurethane adhesive. The board arrangement
may be adjusted during the next 5 minutes or so.
When boards are affixed on vertical surfaces,
baseboards should be used. The affixed boards
should additionally be fastened mechanically with
studs (at least 8 studs per 1 m2 i.e. at least 4 studs
per board).
Where TO-KPS polyurethane adhesive is used to
affix plasterboards or circumferential boards to
insulate the foundations, apply the adhesive on
the wall surface with strips of 3 cm at distances of
approx. 25 cm. During the work the temperature
of base surface and of the environment should be
between +5°r;C and +35°r;C.
Caution
The product contains isocyanates. Avoid contact
with skin and do not inhale the gases which may
cause an allergy. Do not inhale atomized liquid. It
irritates eyes, respiratory system and skin. During
work wear protective clothing and eye protectors.
The product is extremely flammable. Do not use
near fire and sources of ignition. Do not atomise
towards the direction of a flame or heated materials.
Protect against temperatures of more than
+50°C. Pressurised container. Do not puncture
the can during or after use.
User safety
In addition to the above recommendations, follow good building practice and work-safety rules. The manufacturer warrants the quality of the product but has no influence on the manner, place and conditions of its storage and application. Building work should be done by professionally qualified contractors.
