ABSTRACT:
The method for sealing a seam between adjacent structural panels significantly reduces the time for finishing a drywall in comparison with conventional methods, which use multiple applications of a joint compound to seal the seam. An drywall joint compound is mixed with a synthetic fiber, such as Colombian Fiber, or polypropylene, and sufficient water to facilitate soaking of the synthetic fiber and mixing with the joint compound. An optional liquid adhesive, such as liquid liquid adhesive for vinyl wallpaper, or water-based liquid adhesive, is added to the mixture. The mixture is then applied as one coat to the seam and allowed to dry. No subsequent coatings of the mixture are necessary.
