Filling gaps and holes for better insulation

1. Clean the surface

Remove dust, grease and dirt from the hole. To do this use a vacuum cleaner or a good brush. Blow out the last dust and dirt.

2. Moisten the edges of the hole

Moisten the edges of the hole you want to fill. The foam then adheres better and will harden better.

3. Shake the spray can vigorously

Put on protective gloves and safety glasses. Shake the Soudal Expanding Foam canister for 20 seconds. Open the valve of the Genius Gun and raise the applicator straw.

4. Fill the hole

Hold the spray can upside down and spray Soudal Expanding Foam into the hole. Fill the opening approximately 50%; the foam will expand further. Do you have to fill a large surface? Shake the can again regularly and moisten between the different layers. Leave to harden and cut away any excess foam.

Tip:

• Remove non-cured PU foam with Soudal PU Foam Cleaner.
• Make sure you work in a well-ventilated space so the propellants can escape.
• A PU foam can be easily applied with one hand thanks to the Genius Gun. You can also apply exactly the right amount and you can re-use the can for up to 6 weeks. That is handy if you only want to do a few small jobs around the home now and again./li>

The following is also useful:

• Spilt and hardened PU foam can only be mechanically removed (sanded). On non-porous surfaces, you can first make the foam a little softer with Soudal PU Remover.
