Application Instructions
Surface Quality: Surfaces should be clean, smooth, solid, free from all kinds of dust, oil, dirt, rust, mold oil, detergent, etc. 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 should be pre-wetted, but water puddles and drops should not remain.

Mixing: 3.5 - 4.5 liters of clean, clear water, taken from normal ambient temperature, is poured into a clean container free of all kinds of substances preventing adhesion. TEKNOREP 300 EX, which is in powder form and in a 25 kg bag, is poured into the container filled with water. It is mixed with a low speed mixer until a homogeneous mixture without lumps is obtained. Mixing time is minimum 5 minutes. should be. The mortar obtained at the end of the process takes 3 minutes. rest and again for 2 minutes. should be mixed until it becomes homogeneous. After the material has reacted, water should not be added and mixed again.

Application Notes / Limitations
• It should be protected from sun, rain and frost for the first 3 hours in outdoor applications.
• Reaction times in cement based products are affected by ambient and ground temperatures. Reaction times are shortened in hot environments and longer in cold environments.
• Hot mixing water should be used in cold environments.
• In hot environments, iced mixing water should be used.
• It should not be used in contact with liquids with a pH value of less than 5.5. O It should not be used as a final concrete floor covering on large surfaces.
• During the application of the product, work clothes in accordance with the rules of work and worker health should be worn, and appropriate glasses and masks should be used.
• The prepared mortar is applied to the surface with a trowel. If necessary, clover is pulled to ensure the smoothness of the surface. Applications with a wall thickness of more than 40 mm should be made in layers.
• Equipment should be cleaned with water immediately after the application, before it hardens. After the product hardens, it should be cleaned by mechanical methods.
• After TEKNO AD is used as a primer to fuse old concrete with new concrete, TEKNOREP 300 EX is applied with a trowel.
• In strong wind and harsh environmental conditions, TEKNOKÜR 100 can be applied as curing material in order to prevent TEKNOREP 300 EX from cracking.
