Having worked with both embossed plastic sheet and brick papers previously, these sheets are a bit different to work with. They are about the same thickness as embossed plastic sheet, but with a rubbery feel. To achieve sharp corners I have found it necessary to lightly score the rear and fold against a straight edge such a steel rule to achieve a sharp bend. Once you remove the thick paper backing paper to expose the adhesive, the sheet becomes more flexible, but unlike brick paper the sheet needs to be positioned accurately as it can be difficult to re-position.
I have found that if you apply the sheet to plastic sheet, they can be lifted carefully and repositioned if they haven't been smoothed firmly in place, but on card or foam board attempting to move the Redutex will also lift the top surface from the card. This is one of the reasons I clad the foam board building framework in 30 thou plastic sheet. The biggest advantage though of the Redutex is the pre-printed finish.
Hope this helps, Vaughan
