Extrusion coating of a removable thermoplastic material (22) onto freshly painted (non-fully cured paint) surfaces has been found to be an effective method for providing protection against damage during handling, and blocking during stacking, enabling handling of the substrate (10) shortly after painting. Furthermore, the extrusion coating allows the paint (16) to dry and cure on porous and non-porous substrates.
Selon la présente invention, le revêtement par extrusion d'une matière thermoplastique amovible (22) sur des surfaces fraîchement peintes (sur lesquelles la peinture n'a pas complètement durci) constitue un procédé efficace pour protéger lesdites surfaces contre d'éventuels dommages lors de la manipulation et contre des adhérences de contact lors de l'empilage, ce qui permet la manipulation du substrat (10) peu de temps après le travail de peinture. En outre, le revêtement par extrusion permet à la peinture (16) de sécher et de durcir sur des substrats poreux et non poreux.
