install laminate cut to length horizontally with glue and with a special mould at the edge which is the same one used between the transition from laminate floor to carpet, supplied by the same manufacturer.
install laminate on the veritcal surface solely by glue
Is this a proper way of doing it? or I should forget about the special mould and screw down a regular stair mould at the edge...
or it is more complicate than that for professional look finished
Typically the transition pieces that are made for and sold with laminate flooring are made of paper. They have a very thin laminate coating but below that is compressed paper fiber in most cases. Those pieces used in a doorway is one thing but to use them on a stair tread edge where footwear is slidng and scuffing across the edge daily may not be adviseable. Maybe a metal stair edging would be better.
