How to Master the POLYESTER PUTTY APPLICATION

► Tips to optimise the bodywork putty (body filler) application. Let us now look at the steps that will allow optimising the putty application process, while increasing the profitability of the repair. 1. Correct choice of putty according to the type of repair It is essential that the bodywork putty used adheres well to the type of material to be applied, whether plastic or metal, and that it is compatible with the primer. It should be noted that putties should never be applied over wash primers, or acid primers or phosphate primers, as they are incompatible with this type of product. As usual, the different compatibilities between the putty and the type of material to be treated will be stated in the data sheet. 2. Correct pre-surface preparation Before starting with the filling, the painted damaged edges to be repaired should be levelled, sanding the surface with a grit sandpaper between P80 – P120 and 5mm orbit, depending on the repair. 3. Correct preparation of the mix First of all, check that the working tools have no traces of putty or hardener used in previous repairs, in order to make a smooth and regular application on the surface. 4. How to apply the polyester putty In this step the concept “pot life” of the mixture, that is, the time you have between the moment you mix the putty with the hardener until the mixture hardens, becomes especially relevant. This time may also be influenced by both ambient and substrate temperature. When applying the putty, it must...
