Waiting time to overcoating

Min.: Until drying stage 6 is achieved.

Higher layer thicknesses, but also lower temperatures than specified, lead to longer drying times. The overcoating intervals can be delayed and may need to be determined on site.

Max.: 4 years

In case of longer waiting times please contact us.
 

Prior to further applications: After a waiting period or after exposure to weathering, all possible contamination must be removed from the surface before the subsequent coating is applied.
 

Note, if using as a sealer: Pre-spray the thinned SikaCor® EG-1 Plus thinly onto the thermal-sprayed zinc coat and after a waiting time of approx. 15 minutes, spray ‘wet on wet’ the missing layer thickness of SikaCor® EG-1 Plus.

Thinner

Sika® Thinner EG
Adapt the viscosity: If necessary add max. 5 % Sika® Thinner EG.

If used as a sealer: Thinn with 20 % Sika® Thinner EG. Use the heavily diluted material immediately and under constant stirring.

Drying time

Final drying time
Depending on film thickness and temperature full hardness is achieved after 1-2 weeks. Tests of the completed coating system should only be carried out after final curing.

Application steps

MIXING

Stir component A very thoroughly using an electric mixer (start slowly, then increase up to approx. 300 rpm). Add component B carefully and mix both components very thoroughly (including sides and bottom of the container). Mix for at least 3 minutes until a homogeneous mixture is achieved. Fill mixed material into clean container and mix again shortly as described above. During mixing and handling of the materials always wear protective goggles, suitable gloves and other protective clothings.

APPLICATION

The method of application has a major effect on achieving uniform thickness and appearance. Spray application will give the best results. The indicated dry film thickness is easily achieved by airless spray. Adding solvents reduces the sag resistance and the dry film thickness. In case of application by roller or brush, additional applications may become necessary to achieve the required coating thickness, depending on type of construction, site conditions, colour shade etc. Prior to major coating operations a test application on site may be useful to ensure the selected application method will provide the requested results.

 

By brush and roller

Conventional high pressure spraying:

  • Nozzle size 1.5 - 2.5 mm
  • Pressure 3 - 5 bar
  • Oil and water trap is compulsory


Airless-spraying:

  • Pressure min. 180 bar
  • Nozzle size 0.38 - 0.53 mm (0.015 - 0.021 inch)
  • Spraying angle 40°- 80°
