Smooth flat substrates (for indoor floors) are generally the easiest to install and choose a film for application. Examples of smooth substrates include linoleum floors, sanded/painted marble or concrete and finished wood floors.
A 3-4 mil thick calendered film is generally most ideal, either with a permanent or removable adhesive.
Avery Dennison Easy Apply™ is super fast and easy to install and allows simple removal of air bubbles.
A UL classified slip resistant overlaminate is recommended to protect your graphics.
Rough or textured substrates (for indoor floors) can be trickier to install. These included painted concrete or ceramic tile floors. For these we generally recommend a cast vinyl so it can conform to the peaks and valleys of the texture.
For short term graphics (ideal for conference centres, events and trade shows) we recommend a permanent adhesive calendered film, as there's no point using a high performance cast vinyl for these applications.
