Mineral Textured Silicone Decorative Coating

BOYTİM 820

Description:
Cement-based, silicone added, polymer, and fiber-reinforced
mineral textured decorative coating.
Areas of Use:
It is used as a top coat decorative coating on the exterior and
exterior thermal insulation systems of all buildings.
Advantages:
• Easily patterned.
• Gives the construction a natural and decorative appearance.
• Resolves surface defects.
• Creates a surface ready for painting.
• Flexible, it minimizes the risk of cracking.
• Has high water vapor permeability.
• Resistant to severe climatic conditions.
• Thanks to fiber reinforcement, it does not crack and spill.
• Its water repellency feature has been developed with silicone
reinforcement.

Application Information:
Application Temperature: (+5°C) – (+35°C)
Mixing Ratio: 5.5-6.5 lt water / 25 kg powder
Usable period: 2 hours
Average Consumption: 3-4 kg/m²
*These values are valid for 23°C of temperature 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.
-The surface should be smooth and firm.
-The surface must be moistened before the application.
Mixture Preparation:
25 kg BOYTİM 820 is slowly added to 5.5 – 6.5 liters of water. Stirred
until a homogeneous mixture is obtained with a trowel or a low

speed mixer, leaving no lumps.The mortar is rested for 5 minutes
and is then mixed again and made ready for use.
Application:
The prepared mixture is applied on the surface with a steel trowel
in uniform thickness. Application thickness should be adjusted
according to the largest grain size in the material. Excess material
on the surface should be cleaned. The application surface should
be patterned with circular movements with a plastic trowel. The
trowel surface should be cleaned frequently during the process.
-The patterning process should be done while the material is wet.
-It should be applied to the surfaces, that are connected to each
other, at once.
-The surface should not be left as a top coat, after drying, it should
be painted with silicone-added exterior paint.
-After drying (about 2-3 days later), the paint application can be
started.
-In hot and windy weathers, the surface should be moistened
at certain time intervals to prevent sudden water loss on the
application surfaces and to eliminate the risk of cracking.
Applications should not be carried out in temperatures below -5°C.
– Applications should not be made on surfaces that are exposed to
sun and wind directly, without taking protective measures.
-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.
