Advantages
  • Perfect adherence and elasticity.

  • Ensures waterproofing.

  • Establishes stable and permanent bond.

  • Decreases surface absorptiveness once applied on absorptive surfaces.

  • High resistance against oil and salt solutions.

  • Dries without crack and abrasion resistant.

  • Enhances chlorine impermeability.

  • Does not lead to corrosion and saponification.

Areas of Use
  • Used as primer under self-spreading screed in and on

  • As admixture for improving waterproofing of interior and exterior plasters at reinforced concrete silos, water tanks, pools and treatment plants

  • As adherence admixture in mortars prepared for repairing disturbed concrete surfaces, screeds and plasters

  • To ensure adherence between old and new concrete

  • Engineering structures such as subway, highway, tunnel and dam

  • To prevent dusting and cracking of screed

Method of Application

YAPIFINE LATEX is used from 1: 1 to 1: 4 of the water used in concrete. It is poured into the truck mixer arriving into the building site. The concrete mixer is stirred for 5 minutes at high speed. The concrete is placed in the mold. Concrete prepared with
YAPIFINE LATEX is recommended to be used for special purposes. It minimizes the chlorine and water impermeability. To increase the adherence and water impermeability in screed: At the building site, 50 kg of cement for 150 kg of sand is prepared asa dry mixture. YAPIFINE LATEX is poured into a clean barrel in 30 kg bins. Then 4 drums of water are poured into the barrel. Depending on the humidity in the sand, the YAPIFINE LATEX: Water ratio can be changed from 1:1 to 1: 4. The barrel is mixed homogeneously. The prepared dry mortar is opened by mixing with YAPIFINE LATEX and water mixed liquid form. In order to increase the adhesion between the old and the new concrete or to use it as a base coating before plaster: It is used to prevent cold joint formation on new concrete or screed applications on old concrete and to increase adherence. A: 1 kg of cement and 3 kg (O - 3 mm) washed stream sand is mixed. B: 1 kg of YAPIFINE LATEX is mixed with 2 kg of water. Mixtures A and B are mixed together until the mixture has a thick consistency. The prepared mixture is applied on the surface soaked with a brush for 12 hours beforehand to a thickness of 2 mm. Before the mortar dries within 20 minutes, plaster, screed and concrete applications are also done on top of it.lf it is to be used as rough before plastering: Prepared mortar is sprinkled rapidly on concrete surface with trowel. Rough or fine plaster is applied next day after the rough rendering is dried. To increase the water impermeability in the plaster: At the building site, 50 kg of cement for 150 kg of sand is prepared as a dry mixture. YAPIFINE LATEX is poured into a clean barrel from 30 kg bins. Then 4 bottles of water are poured into the barrel. Depending on the humidity in the sand, the YAPIFINE LATEX: Water ratio can be changed from 1:1 to 1: 4. The barrel is mixed homogeneously. The dry mortar is added to the prepared liquid mixure and then they are mixed together as well. Then the application may begin with a trowel.

Packaging

10 kg and 30 kg plastic drum

Safety Measures

The operator should be wearing proper work attire, goggles, mask and protective gloves appropriate to work and worker
safety regulations. In case of contact with the eyes, rinse with plenty of water before seeking immediate medical attention.
Rinse with plenty of water in case of contact with the skin. For further information on the safe handling of this product please
read the Safety Data Sheet (SDS).

Application Conditions

To increase the adherence and water impermeability in concrete, the mixing properties of concrete sample decided to be poured on the construction site are as follows.

 

Ambient temperature: Between +5 °C and +30 °C. Avoid application under strong wind or direct sunlight. Avoid application
in areas with risk of freeze in 24 hours, as well as those directly exposed to sunlight and wind. Never add any material not
indicated in operation manual. The final consumption amount might vary depending on application conditions and surface
characteristics.

Consumption

YAPIFINE LATEX/Water Rate is between 1:1 and 1:4.
