Verschweißung und Verfugung
In Flächenbereichen mit hygienischen Anforderungen, bei Feuchtigkeitsbelastungen (Nassräume) und bei Räumen mit intensiver nasser Reinigung ist ein Verschweissen der Bodenbeläge immer notwendig.
The welding process
Adhesive recommended by the manufacturer is required installing linoleum and rubber. Usually 0.12 to 0.2 inch welding rod of the same material, that is recommended by the manufacturer is used for welding PVC or TPU surfaces.
Before welding, the seam edges are grooved to approx. 2/3 of the thickness of the surface and then heat seam welded with the welding rod.
It is important that the welding rod is fully melted into the milled surface created by the groover. The rod is then trimmed level to the surface in two steps using the Leister quarter-moon knife: In the first stage, the rod is trimmed using the half moon knife and slide immediately after welding/pointing. A second pass is made with the knife once the welded seam has completely cooled down. This prevents the welding rod from being trimmed below the level flooring material and produces an even, flush surface.
