TIPS

• Application temperature from +5 °C to +40 °C.
• The surfaces must be clean from fat, oil, dust and loose particles.
• The surface to be covered must be dry.
• The product cures by means of desiccation (water evaporation).
• High humidity, low temperatures and high joint depth can delay skin formation and curing significantly.
• It is strongly recommended to cover cured caulk with a suitable paint to guarantee its longevity and similar colour shade with the background surface.
• Paintable after the final curing.
• Curing time depends on the size of the joint.
• Early painting may cause cracking of the paint.
• Ensure adequate ventilation in all joint locations.
• During the curing process, make sure that no impurities can settle on the surface and that the joint surface is not affected by mechanical load.
• Do not use at temperatures below +5 °C.

LIMITATIONS

• Not suitable for joints with considerable movement (more than 5% of joint width).
• Not suitable for connections in constant contact with water.
• Not suitable in connection with bitumen surfaces.
• Poor adherence to glass and some plastics.
• May cause corrosion on exposed metal surfaces.
• After curing, cannot be grinded as putty.
