Polyurethane foam in an aerosol can appeared more than 50 years ago. Today it is one of the most important materials inherent in the labor process. Despite the seeming simplicity, you can do various interesting things with a can of polyurethane foam, which will primarily help make life easier.
1. Filling in hard-to-reach places
Surely everyone who has worked with polyurethane foam at least once faced the need to carry out an insulating filling in some hard-to-reach place. For example, under a roof or ceiling. In fact, the issue can be resolved very simply. It is enough to fix the tube of the spray can on a stick of suitable size using tape or electrical tape. She will help you reach anywhere.
2. No spare tube
If the original tube from the foam cylinder has been lost, then you do not need to be upset right away. Any other can be put on and used on the balloon, as long as its diameter is 6-8 mm. The ideal option would be a heat shrink tube or tube from a hydro level. A washer or small bearing is put on top of it. The foam is ready to go again!
3. The size is not the same
The base tube of the foam cylinder is large enough. This means that it will be quite difficult to close up some narrow cracks and cracks with its help. Here the same heat-shrinkable tube comes to the rescue from which a small cap is made on the tip of a standard tool.
4. Space saving
If you need to fill a large space with polyurethane foam, then it makes sense to use additional materials. For this, the first mounting layer is first made using foam. After that, the foam is placed in the place of isolation. When it is, the remaining free space is filled with foam.

5. Foam doloth
Sometimes, the foam may go in the wrong place. In this case, it is necessary to carry out the cleaning procedure. The widely available means "Dimexid" will help in this difficult matter. It is sold in almost every pharmacy. The product will quickly and easily remove any remaining dried foam. It works much better than acetone.
