Sika® Thinner S
If necessary max. 5 % Sika® Thinner S may be added to adapt the viscosity.

Min. + 5°C

Min. 30 %, max. 98 %, surface temperature shall be at least 3 K above dew point.
The surface must be dry and free from ice.

Min. 0°C

Between primer coat and intermediate coat (at + 20°C):

In case of longer waiting times please contact us.

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

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.

Final drying time
Depending on layer thickness and temperature final hardness is achieved within several days.

Theoretical material-consumption/VOC without loss for medium dry film thickness:

Apart from small areas the dry film thickness of 180 µm of SikaCor® PUR-1 should not be exceeded per application.

Steel:
Blast cleaning to Sa 2 ½ according to ISO 12944-4.

Free from dirt, oil and grease.
 

Hot dip galvanized steel, stainless steel and aluminium:

Free from dirt, oil, grease and corrosion products.

In case of permanent immersion and condensation the surfaces must be slightly sweep blasted with a ferrite-free blasting abrasive.
 

For contaminated and weathered surface e.g. galvanized and primed areas we recommend to clean with SikaCor® Wash.

All materials are supplied ready for use; stir thoroughly prior to application.

Attention, risk of injuries! Container may be under pressure. Lid may come off unexpectedly. Prior to opening reduce pressure, e.g. by piercing the lid.

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.
