Application lnstructions
Surface Quality: The surfaces must be clean, smooth, solid, free from any antiadhesive substance such as dust, oil, dirt, rust, mold oil, detergent and waste. Weak parts on the surface should be removed.

Surface Preparation: Cement slurry and weakened parts should be removed, and there should be no materials such as oil dirt and rust on the surface. Absorbent surfaces must be pre-wetted, but there should be no water accumulations. When adherence primer is required, TEKNO AD is applied by brush and TEKNOREP 200 repair mortar is applied on the surface before drying.

Mixing: 4-5 lt clean, clear water received from normal ambient temperature into a clean container which is free from ali kinds of materials which prevent adhesion. TEKNOREP 200 in 25 kg bag as powder is poured into a container filled with water. The product is mixed with a low speed mixer until a homogeneous mixture without lumps is obtained. Mixing time should be at least 5 minutes , the mortar obtained at the end of the process should be rested for 3 min. and mixed again until it becomes homogenous for 2 min. After the material has entered the reaction, it should not be mixed again with water.

Application Notes / Restrictions
• For outdoor applications, the first 3 hours of sunshine should be protected from rain and frost.
• in cement based products, reaction times are affected by ambient and ground temperatures. Reaction times are shortened in a hot environment, and extend in a cold environment.
• Do not add too much water as recommended.
• Do not use the material below the minimum permissible temperature to complete the setting. Low temperatures will slow down setting and high temperatures will speed up setting. The workability time will also vary depending on the temperatures.
• During the application of the product, work clothes suitable for occupational health and safety rules should be worn and appropriate glasses and masks should be used.
• lf necessary, clover is applied to ensure surface smoothness. Applications with wall thickness over 30 mm should be done in coats.
• it must be protected after application against adverse weather conditions such as direct sunlight, high air temperature (above +35 °C), rain and frost. The product should be cleaned thoroughly with water and detergent before it is fully cured and hardened.
• lmmediately after application, before hardened, the equipment should be cleaned with water. After the product is hardened, it should be cleaned by mechanical methods.
