Vinyl may be heat welded immediately. Installations may be subjected to rolling loads and heavy traffic without waiting.
Roll out Sigaway® perpendicular to new flooring. Overlap and double cut seams. For carpet over carpet use Siga construction tape to re-enforce perimeters and seams beneath the Sigaway®. Unroll new carpet or vinyl, seam seal as per manufacturer's specifications. Roll and put into service.
