01

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.
