Article for prepping/flattening a floor

Abstract

An article, system and method for flattening a three dimensional depression within a substrate floor. A straight edge is applied in a progressive X and Y grid fashion across the depression, with varying levels of shims defining contact locations, thereby establishing a floor template identifying common depths of depression at overlapping perimeter defined boundaries. One or more thermo-polymer sheets is resized to define an outer perimeter matching that of a perimeter boundary. A subset thickness of the sheet is incised around its outer perimeter to establish a feathering effect upon the sheet prior to it overlaying the boundary perimeter and prior to sizing and application of additional overlapping sheets up to an outermost boundary corresponding to a shallowest depression.

1 . A sheet for flattening a depression in a floor surface, comprising:
 a body exhibiting a specified length, width and thickness and further comprising at least first and second plies defining subset thicknesses; and   a separating layer interposed between said plies of sheet material;   at least one of an outer perimeter of said body and an outermost band of material of a selected ply being removed prior to said body being secured to a surface of the depression.   
     
     
         2 . The sheet as described in  claim 1 , said body exhibiting a specified shape and size and further comprising a total thickness no greater than ¼″, with a selected ply thickness of between ¼ and ½ said total thickness. 
     
     
         3 . The sheet as described in  claim 1 , said sheet having a specified shape and size and being coated with at least one of a moisture impervious membrane and a mold inhibitor. 
     
     
         4 . The sheet as described in  claim 1 , said sheet having a specified shape and size and being constructed of at least one of a thermo-polymer and a vinyl material. 
     
     
         5 . The sheet as described in  claim 1 , further comprising a plurality of underlayment ring shank nails for securing said body within said depression. 
     
     
         6 . The sheet as described in  claim 1 , further comprising a tacky layer applied to an exposed surface of said sheet and which is covered by a peel-away layer.
