Cement-Acrylic Based Semi-Flexible Waterproofing Material

BOYTİM 900

Description:
It is a semi-flexible waterproofing and concrete
preservative mortar which is enhanced with
superior properties of cement-acrylic based,
double component chemicals providing
waterproofing.
Areas of Use:
It is used on any kind of concrete, cement
finish and plaster surfaces; all wet areas such
as kitchen, bathroom, WC, balcony, terrace,
etc; pools and water tanks for waterproofing
processes of places such as foundation and
face walls.
Advantages:
• Easy to apply.
• Has high adhesion force.
• Resistant against freeze-thaw effects.
• Used in indoors-outdoors, vertical-horizontal
applications.
• Can be safely applied and does not crack
thanks to its high level adhesion and semiflexible features.
• Can be used in terraces, water tanks and
swimming pools provided that its surface is
protected.
• Is the ideal waterproofing material prior to
ceramic coating or cement finish.
• Not corrosive for reinforcement.
• Suitable for use in drinking water tanks.
Application Information:
Application Temperature: (+5°C) – (+35°C)
Mixing Ratio: 5 kg liquid / 20 kg powder
Workable Period: 2 Hours
Waiting Period Between Layers: 5- 6 hours
Grouting Period: 1 week
Average Consumption: First coat: 1.50 kg/
m²(For 1 mm thickness depending on surface
roughness)
Second coat:1.30 kg/m² (For 1 mm thickness
depending on surface roughness)
Third coat: 1 kg/m² (For 1 mm thickness
depending on surface roughness)
*These values are valid for 23°C and 50%
relative humidity. Times may vary depending
on ambient conditions.
Surface Preparation:
-The application surface should be made
clean from dust, dirt, oil, paint residue, and
similar foreign matters reducing adherence.
-It should be ensured that the application
surface is set.
-Any surface breakdowns, roughness, and
eyelet pores should be repaired with BOYTİM
PLASTER 1 day before the application, and
corner chamfers should be necessarily made.
-The floor should be dampened, moistened,
and saturated with water.
Mixture Preparation:
20 kg BOYTİM 900 powder component is added
slowly into a 5 kg liquid component. It is stirred
with a low-speed mixer for at least 3 minutes
until a homogenous and fluid mixture without
lumps is obtained. The mortar, which is rested
for 5 minutes, is stirred again for 30 seconds
before the application and made ready for use.
Application:
The prepared mixture is applied to the surface
with a brush or roller in minimum two layers.
It is applied by feeding thoroughly to cover
the entire surface in a way that it does not
form pores. The second coat application can
be started at least 5 hours after the first coat
application. The second coat application
should be done just like the first coat
application. However, the application of each
coat should be done in the vertical direction of
the previous coating. Application made in 90
degrees rotated direction eliminates the risk
of pores. Wait for maximum 1 day before next
coat.
It should be applied in at least 2 coats.
Depending on the water height, 3 coats may be
required.
– Chamfering tape should be applied to the
corners and joints in the application area. In
cases where there is no chamfering tape, the
joint details should be ovalized, and the mortar
should be reinforced with mesh.
-Applied floors should be coated with a
topcoat such as cement finish, ceramic, etc.
-At least 7 days should pass for the application
surface to be ready for use and flooring.
– If the application area is a water tank, the
product should be waited to be cured for at

least 28 days.
– During the coating process, care must be
taken to avoid mechanical damage to the
insulation material.
-The mortar, which begins to harden, should
not be used.
-The mixture should be prepared only with its
own liquid, water should never be added.
Applications should not be carried out in
temperatures below -5°C.
-The application surface should be protected
from sun, rain, and dust for 1 day, and
protective measures should be taken during
application on surfaces which are directly
exposed to sunlight and wind.
-Foreign materials should never be mixed into
the mortar.
-After application, all used tools should be
washed with plenty of water before drying.
Warnings:
Do not breathe the product directly, as it is
cement-based. Avoid contact with skin and
eyes.
