SAKRET BK FOAM SB / Polyurethane glue for fixing insulation boards, winter

Polystyrene Glue Overview

Polystyrene glue is used for fastening insulation boards to facades and foundations, securing interior design boards to walls, and fixing roof tiles and thermal insulation for both thermal and sound insulation purposes.

Advantages and Application

• Compared to traditional gluing methods for facade boards and modern foam adhesives, this glue is easier, faster, and more cost-effective.
• Excellent adhesive and sealing properties.
• Strong adhesion to various materials, including foam polystyrene and mineral substrates.
• Highly economical, saving both time and money.
• Provides an even and strong structure with sufficient elasticity.
• Low post-expansion allows for fast and accurate adhesion.
• Achieves high-quality results under various weather conditions.
• Can be applied using a foam gun.

Installation Instructions

1. Preparation:

   • Hold the foam can in an upright position.
   • Attach the gun to the can by holding the gun handle with one hand and turning the can with the other hand.
   • Ensure the gun is not pointed at other individuals while turning it.

2. Attachment:

   • Do not screw the can onto the gun with the valve upside down or by turning the gun on the can.
   • After securing the gun, shake the can well at least 20 times. The foam output can be adjusted using the gun trigger.

3. Substrate Treatment:

   • In low humidity conditions (under 50% RH), moisten the substrate, as the foam expands due to moisture.
   • A moistened substrate ensures faster curing and better results.

4. Temperature Considerations:

   • Warm the glue can before use in a warm room or in water at low temperatures.
   • The temperature of the room or water should not exceed +30 °C.

5. Application:

   • Apply the foam adhesive to insulation boards in an even flow, running parallel to the edges (3–4 cm from the edge) and adding one stripe in the middle, parallel to the longest side (up to 25 cm between adhesive stripes).
   • After applying the foam adhesive to the insulation board, wait 2–3 minutes before pressing the board against the wall.

6. Adjustment:

   • The level of installed foam polystyrene boards can be adjusted within 5 minutes.
   • Use fastening equipment for balconies, ceilings, or long spans.
