After two failed attempts to joint a basin with the Pattex donor, I have disposed of the product, and resorted to a classic silicone syringe. The dispenser is a nice idea works in practice, however, not satisfactory. The silicone comes with such low pressure from the donors that it was not put into the joint. You have to then push it with your finger, which will correspondingly uneven. Vertical or overhead to add is hopeless. The silicone simply falls to the ground as soon as it has been plagued from the dispenser.
After everything was cleaned, the wash basin on the following day was grouted successful classical syringe in a few minutes. Sometimes traditional methods are second to none.
