Application procedures

Preparation of the surface. Please pay attention to the treated surface: it should be strong and free of residues deteriorating adhesive force (dust, oil, etc). Containers used for AGDAG DIREK plaster preparation should be clean. In order to prevent wall corner spalling in hot weather conditions, and to make them regular and neat it is necessary to place special corner sections  in the corners. In the points of different material connection and areas subject to movement plastic plaster lath should be placed. In case the surface is too smooth, there is no need to use handicraft methods to make it rough. To prevent plaster spalling and to achieve roughness, such surfaces  should be treated with PARAKONTAKT plaster bonding coat which provides two-way bonding effect between the base surface and the applied plaster. This should be done at least 24 hours prior to application of the plaster. Metal surfaces should be protected from corrosion by means of treatment with anti-corrosion solution before application of  DIREK plaster. At the time of carrying out the work the ambient and surface temperatures should be between +5°C and +30°C. AGDAG DIREK prime plaster should not be mixed with any additives or substances other than water.

Preparation of the mixture. Pour 10 kg of AGDAG DIREK powder plaster into 6.0 - 6.5 liters of water, wait 3-4 minutes, then mix using a mixer or any suitable hand tool till it is entirely homogeneous. After preparation of DIREK primer do not add any fresh plaster or water to it.

Application. Apply the prepared primer directly onto the ready wall or ceiling (not plastered with sand and cement mixture). It is allowed to apply the AGDAG DIREK primer onto the regular walls or ceilings plastered with sand and cement mixtures, but as the sand-and-cement plaster may be harmful for health, due to high repair costs it is not recommended to apply the primer onto such mixtures). Generally the DİREK primer is applied onto the surface at 0.8-1.0 cm thick layer minimum. Depending on the surface type, if required, in 24 hours after application of the AGDAG DIREK, the mixture prepared from DIREK primer and AGDAG white plaster can be applied onto the surface. To prepare such mixture it is recommended to use 85% of DIREK primer and 15 % of AGDAG white plaster in its composition. In approximately 24 hours after that the AGDAG white plaster can be prepared and applied onto the surface. The amount of 10 kg AGDAG white plaster powder mix applied at the level of 0.5 – 1.0 mm thickness form a defect-free surface. The prepared AGDAG DIREK primer mixture should be applied within 100-120 minutes, and white plaster mixture - within 130-150 minutes. The mixtures should not be used after this period expired or crust formed.

Recommendations. If at the time of AGDAG DIREK primer application the ambient temperature exceeds the limits of +50C - +300C range, then the required temperature level should be provided. The product should not be used in warm (above +300C), rainy and windy weather conditions. The can and the equipment used for preparation of the mixture should always be clean. Dirty cans and tools reduce the useful life of the mixture. After use all hand tools and devices should be immediately cleaned with water.


The AGDAG DIREK plaster primer consumption at minimum 8-10mm thick layer is 9 kg/m2. Hence, 1 sack (30 kg) of AGDAG DIREK prime plaster is enough to cover the area of approximately 3 m2.

Shelf Life and Storage Method

The product can be stored during 6 months in packaged sacks in closed areas, in dry conditions, on wooden racks, maximum 10 sacks per rack placed one over another, provided they do not contact with the floor.


  • pay special attention to clean conditions of cans and water used for preparation;
  • do not add to the primer any substances other than water;
  • parameters indicated above have been received on the basis of laboratory tests conducted in the ambient conditions of +230C±20C temperature and 50% + 5% humidity. Depending on the actual ambient conditions these parameters are subject to change.
