The metal axle needs to be clean from old screen fabric or from glue residues. To fix the screen fabric to the metal axle you will need first the aggessive tape and afterwards the spray glue. Roll up the screen completely to the axle, without spray glue and agressive tape, just to see that it is rolled up in a straight way. Now unwind the fabric and fix the top of the screen fabric with the agressive tape to the metal axle, tape half to the axle and half to the screen fabric. Afterwards spray the axle with the spray glue and roll up just one roll. Let it be and wait 24 hours until the glue is dry.
