Installing American Forest Threshold With a Floating Floor
When installing Threshold moldings on a floating floor, it is important not to attach the molding directly to the hardwood floor as the hardwood floor must be able to expand or contract under the lip of the molding per the American Forest Hardwood Flooring installation recommendations.
After the hardwood floor is installed, lay the Threshold molding in place. The Threshold molding should overlap the flooring by 1/2 to 3/4 inch, leaving the balance for required expansion or contraction. To attach the molding, apply one or two 1/4 inch beads of construction adhesive to the subfloor and seat the molding in place. If nailing, pre-drill the molding to prevent splitting and nail to the subfloor behind the lip of the molding. Be sure when nailing, not to obstruct the floor's expansion space under the molding.
