If you are fond of do-it-yourself and personally mounted your home’s internal and/or external window casings, you probably used polyurethane foam to fill cracks and cavities or to bind different parts together.
Polyurethane foam has a light yellow colour and within the space of 2 or 3 hours, as its initial volume increases by up to 3 times, it moves from the foamy to the solid state, completely filling even the most non-homogeneous cavities through its expansion.
How can polyurethane foam residues be removed?
With ZERO SIL this problem can be solved in 20 minutes in just a few steps:
- in the box you will find a plastic trowel that does not scratch ceramic or glass: use it to remove any excess polyurethane foam
- after shaking the ZERO SIL can, apply the product pure on whatever remains on the surface, so as to completely cover any residue present
- leave the product to take effect for at least 20 minutes
- once the polyurethane foam has softened, collect the residues with a cloth or absorbent paper.
Remember: ZERO SIL also removes residues of silicone, glue, adhesive tape and old labels. Read here how to proceed.
