Waiting time to overcoating

Before applying Sikafloor®-359 AE on basecoats allow waiting time of:

Substrate temperature

Minimum

Maximum

+10 °C

~36 h

~72 h

+20 °C

~24 h

~48 h

+30 °C~16 h~36 h

* On fully broadcasted basecoats no maximum waiting time applies. Make sure the fully broadcasted surface is free of dirt, oil, dust or any other contamination.
Times are approximate and will be affected by changing ambient conditions particularly temperature and relative humidity. Refer to PDS of relevant base coat for more information.

Consumption

Consumption

~0.2 – 0.25 kg/m2/coat depending on system, surface profile (roughness), exposure and area of application.

Note: These figures are theoretical and do not include for any additional material required due to surface porosity, surface profile, variations in level and wastage etc..
Application steps

EQUIPMENT

Sikafloor®-359 AE must be thoroughly mixed using a low speed electric stirrer (300 to 400 rpm) or other suitable equipment.

MIXING

Mix full kits only. Prior to mixing, stir part A mechanically. When all of part B has been added to part A, mix continuously for 3 minutes until a uniform mix has been achieved.
To ensure thorough mixing pour materials into another container and mix again to achieve a consistent mix. Over-mixing must be avoided to minimise air entrainment.

APPLICATION

Prior to application, confirm substrate moisture content, relative humidity and dew point. As a seal coat, the product can be applied by roller or squeegee and then back-rolled (crosswise) with a short-piled roller.

 

CLEANING OF EQUIPMENT

Clean all tools and application equipment with Sika® Thinner C immediately after use. Hardened and/or cured material can only be removed mechanically.
