The maximum content of Sikagard®-520 W is < 20 g/l VOC for the ready to use product.

Note ⁽¹⁾ Please refer to the respective data sheet for additional information.
Note ⁽²⁾ For very difficult substrate (very dense or weak tensile adhesion strength / pull off < 1 N/mm²), primer application is recommended.
Note ⁽³⁾ In case of an intensive yellow or red colour shade and/or a dark substrate, more than two coats might be required.

Recommended minimum dry film thickness to achieve the required characteristics ≈100 microns.

+8 °C min. / +40 °C max.

< 80 %

Temperature must be at least 3 °C above dew point.

+8 °C min. / +40 °C max.

Sikagard®-520 W does not require any special curing but must be protected from rain for at least 4 hours at +23 °C.
Full cure: ~7 d at +23 °C

Note:

• 300 g of coating applied over 1 m² will give approx. 100 µm dry film thickness
• Some substrates will require higher consumption than indicated above. This figure is theoretical and does not include for any additional material required due to surface porosity, surface profile, variations in level and wastage, etc..

Depending of substrate porosity and required pull-off strength, apply Sikagard®-552 W Aquaprimer (G) evenly onto the substrate.

Apply leveling putty from SikaWall® or Sikagard® range with spatula or trowel, for rectifying minor surface defects, mechanically damaged areas and hairline cracks. When harden, dry sandpaper may be used for smoothening of the surface if required.

Sikagard®-520 W can be applied by brush, roller or airless spray, in one or two coats.

Clean all tools and application equipment with clean water immediately after use. Hardened / cured material can only be removed mechanically.
