All Polyflor vinyl sheets and 608mm vinyl tile floorings should be welded, according to Polyflor. Since welding prevents dirt and bacteria from getting into seams and creates a water-resistant floor surface, most requirements require it. However, if welding is done correctly, it will only help maintain high levels of hygiene. Given that welding shortcuts might lead to seam failures, the rules listed below should be properly followed.
Heat welding of vinyl floorcoverings has been used successfully for many years and employs the technique of heating both the vinyl flooring and the vinyl welding rod to a suffıcient temperature to melt and fuse them together. The procedure is the same for both sheet and tile installation with the exception that the edge of the tiles does not require cutting in prior to grooving.
