Beware of condensation. The substrate and uncured applied product must be at least +3 °C above dew point to reduce the risk of condensation on the surface of the applied product.

Before applying Sikagard®-407 W on Sikagard®-407 W, allow:

Before applying Sikagard®-407 W on Sikagard®-403 W, allow:

0.20 kg/m² per layer

0.15 L/m² per layer

Note: Consumption data is theoretical and does not allow for any additional material due to surface porosity, surface profile, variations in level, wastage or any other variations. Apply the Product to a test area to calculate the exact consumption for the specific substrate conditions and proposed application equipment.

IMPORTANT Avoid air entrapment. Use an electrical stirrer at low speed (300–400 rpm) to stir the Product until a uniform liquid has been achieved.

WARNING

Hazardous respirable droplets may be formed when sprayed. Do not breathe spray or mist.

IMPORTANT

• Reduced service life may be observed due to incorrect treatment of cracks. The incorrect assessment and treatment of cracks may lead to reduced service life and reflective cracking. For static cracks, ensure the width is suitable for overcoating with Sikagard®-407 W.
• For dynamic cracks, ensure the movement is within the movement capacity of Sikagard®-407 W.
• Excess moisture can cause crazing. Crazing may occur if the coating is applied to undried surfaces. Ensure the entire surface is fully dry before proceeding.
• Allow new concrete substrates to cure or hydrate for a minimum of 10 days, and preferably 28 days.
• Incompatibility with silicone sealants: Do not apply over silicone sealants.
• Application on acoustic boards: Acoustic boards may lose their acoustic absorption properties after coating.
• Do not thin or brush out like conventional paints
• Gloss finish may vary
• The gloss of the finish can vary with temperature, humidity and the substrate's absorbency.
• ROLLER APPLICATION: For aesthetic reasons, use the same roller type in the same areas. Apply the Product to the correct film thickness per layer with a short-pile roller.
• AIRLESS SPRAY APPLICATION: This method produces a smoother surface than the roller application.
• Use the same application type in the same areas. Apply the Product to the correct film thickness per layer with airless spraying application equipment, using tip sizes from 0.38 to 0.53 mm and a fan angle from 40° to 60°.

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