There is certainly a product for every application, non so more important than in the vinyl graphics world. Monomeric vinyl is produced with few polmers in it, which over shorter periods of time begin to break down, which in turn cause the vinyl to crease and shrink, eventually curling back on itself and falling off.
We only use polymeric or cast vinyls for this reason, they are stable and contain their shape for a far longer period. this is important in the application of wall murals to firstly create a strong bond to the surface and ultimately to last the distance for the application.
We recomend the same process with digitally printed glass splash backs, monomeric vinyl tests that we did were conclusive that they could not hold the bond between the wall surface and the silicone sealant for a long period of time, thus failing early after the application. Product knowledge is key, tried and tested methods over a 25 year span and a true desire to achieve the best finish possible should be a driving factor when considering a purchase.
