ASTM F1516-08
(Practice)Standard Practice for Sealing Seams of Resilient Flooring Products by the Heat Weld Method (when Recommended)
Standard Practice for Sealing Seams of Resilient Flooring Products by the Heat Weld Method (when Recommended)
SIGNIFICANCE AND USE
Seams in some resilient flooring are heat sealed to prevent openings from forming between cut edges and to prevent penetrations of dirt, liquids, etc., into the seams. Decorative appearances may also be achieved using contrasting heat weld thread (rod).
SCOPE
1.1 This practice covers the instructions and precautions to be observed to ensure satisfactory performance of seams in resilient flooring sealed by the heat weld method.
1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. See precaution information in 6.1.

5. Instructions
5.1 Flooring shall be installed in accordance with the manufacturer’s instructions.
5.2 Particular attention shall be paid to proper cutting of seams and tightness of cut seams. Specified tightness of seams to be
heat sealed (welded) will vary depending on the flooring product and type of tools used to perform the heat weld.
5.3Prior to heat welding, seams shall be routed to a depth specified by the manufacturer. Routing can be accomplished with
electric or hand routing tools as specified by the manufacturer. Follow flooring manufacturer’s instructions for specific details.
5.4Routing and heat welding of seams normally are performed the day after flooring is adhered (installed) to allow adhesive to
dry. Some tile products are routed at the factory, and on site routing is not required. The process involves the melting of thread
(rod) into the gap of a routed seam. Special electric hot air tools with variable temperature settings are required. Because

and welding rod composition, a trial length shall be performed and tested after cooling to determine if the bond and appearance
of the weld thread to the seam edges is satisfactory. Weld threads are available in various colors to match the color of the flooring.
Accent thread colors are also available. Use weld thread (rod) as recommended by the manufacturer of the flooring.
5.5Approximately one-half of the weld thread thickness will adhere to the seam. The excess will be trimmed off flush with the
surface of the flooring when cooled. Trimming of excess weld thread is accomplished in one step for rubber products and in two
steps for vinyl and linoleum products. Generally, it is recommended to let welded seams cool before trimming. There are a few
exceptions, so follow manufacturer’s specific recommendations. Trim knives and attachments are available from the flooring
manufacturer or various flooring installation tool suppliers.
5.6Some manufacturers recommend use of a final glazing with either the heat gun or use of a chemical sealer to reduce the
porosity and seal the top surface of the weld. Follow manufacturer’s specific recommendations.
