7 Profiling / connection systems

Lock-it 5G (= glueless) connection

Connection systems

2 systems are offered to connect the floorboards: the classic tongue and groove system for professionals and skilled craftsmen and the glue-less installation system lock-it 5G. 

Filling of knots, cracks …

Before the connection systems are made, cracks, knotholes or branches have to be filled with a filler.  Depending on the sorting and characteristics the floorboards are filled either brown or black. Rustic floorboards are perceived even more intensely thanks to the black filler, while products filled with a brown filler appear calmer.
