McCoy Soudal Soudafoam 1K Polyurethane (PU) Foam 750ml

A Ready-to-use, multipurpose, polyurethane foam that is triple expanding when in contact with moisture. The straw grade foam is easy to apply by simply attaching the supplied straw to the can. There is no need of an application gun. The expansion action fills holes, cracks and gaps more completely than standard caulks. It has excellent adhesion to virtually all construction materials. It also has excellent insulating properties.

The polyurethane foam thus formed is light weight and rigid and is useful in aero modelling too.

Areas of Application

• Filling gaps betweeen door/window frame and wall
• Bore packing for pipes running through walls and roofs
• Installing door frames
• Filling gaps in electrical duct ends
• Excellent as an insulating material
• Used to fill gaps between cabinetry and walls - preventing pests from entering gaps
• Easy to fill uneven spaces due to expanding nature
• Aero-Modelling

Application Procedure

1. Moisten the surface where the foam has to adhere using a water sprayer.
2. Shake the PU foam can well and fix the supplied straw on the spray head.
3. Invert can and spray on to the application area.
4. Fill only 40-50% of the gap with the PU foam.
5. Allow to cure and expand - about 3-4 hours.

7. The excess foam can be sanded or cut using a knife as required.
8. After use, keep the can upright and spray out any excess material remaining in the straw.
