Keep the container well closed and stored in a cool (temperature below 25°C) and ventilated environment for a maximum period of 6 months from the date of production marked on the tin. Avoid direct sun exposure.

Ensure that the surfaces to be bonded are perfectly dry and clean; preferably, sand the two parts to be bonded.

Take the amount to be used from the jar with clean tools. It is possible to colour URANIUM by adding a colouring paste, up to a maximum of 3%: mix the colouring paste with URANIUM and achieving the desired colour.

Adding 1 or maximum 2 grams of paste hardener for every 100 grams of product, to avoid the browning effect. Mix this quantity well, amalgamating the two components.

Apply URANIUM on the surface to be bonded or filled, keeping in mind that the putty hardens completely
after about thirty minutes; hardening times will be shortened at temperatures above 25°C and lengthened at temperatures below.

Do not put hardened and unused putty back into the jar to avoid deterioration of the entire contents. Close the jar after use to prevent the product from hardening upon contact with air.
