Substrate preparation tool system and method

Abstract

A surface substrate preparation tool system comprised of a flexible foam member, a flexible abrasive member, and an adhesive member being affixed on one side to the foam member and on the other side to the abrasive member, wherein the foam member retains at least one liquid agent therein, and wherein a liquid agent can be delivered to the adhesive member or to the foam member during the surface preparation process.

1 . A substrate preparation tool system for working on a variety of substrates, said preparation tool system comprising:
 an absorbent, micro-abrasive foam member comprising melamine foam;   a porous abrasive member having an abrasive surface, said abrasive surface being substantially more abrasive than said foam member, and said abrasive member comprising a synthetic, non-woven material embedded with abrasive grain;   an adhesive member joining said abrasive member to said foam member; and   
       said adhesive member being substantially porous to permit liquid to pass between said foam member to said abrasive member. 
     
     
         2 . A substrate preparation tool system for working on a variety of substrates, said preparation tool system comprising:
 an absorbent, micro-abrasive foam member;   a porous abrasive member having an abrasive surface; said abrasive surface being substantially more abrasive than said foam member;   an adhesive member joining said abrasive member to said foam member; and   said adhesive member being substantially porous to permit liquid to pass between said foam member to said abrasive member.   
     
     
         3 . The substrate preparation tool system of  claim 2 , wherein said abrasive surface comprises an abrasive sanding component rated no less than 7 on Mohs scale of mineral hardness. 
     
     
         4 . The substrate preparation tool system of  claim 3 , wherein said abrasive sanding component is a steel wool. 
     
     
         5 . The substrate preparation tool system of  claim 3 , wherein said abrasive sanding component is made of aluminum oxide. 
     
     
         6 . The substrate preparation tool system of  claim 2 , wherein said foam member comprises melamine, polyvinyl alcohol, or ceramic, or a combination thereof. 
     
     
         7 . The substrate preparation tool system of  claim 6 , wherein said foam member is made of melamine. 
     
     
         8 . The substrate preparation tool system of  claim 2 , wherein said foam member can absorb a liquid volume of at least 90% of a volume of said foam member. 
     
     
         9 . The substrate preparation tool system of  claim 2 , wherein said adhesive member covers no more than about 90% of a contact area between said foam member and said adhesive member. 
     
     
         10 . The substrate preparation tool system of  claim 9 , wherein said adhesive member is in the form of a bead of adhesive material around a perimeter of foam member. 
     
     
         11 . The substrate preparation tool system of  claim 2 , wherein said adhesive member is made of a two-component epoxy. 
     
     
         12 . The substrate preparation tool system of  claim 2 , wherein said foam member, said abrasive member and said adhesive member are substantially chemically resistant to organic solvents like paint thinners, lacquers, and cleaning fluids. 
     
     
         13 . A surface preparation tool system for working on a variety of substrates, said preparation tool system comprising:
 an absorbent foam member having first and second opposed major surfaces;   first and second porous abrasive members, each having an abrasive surface;   a first adhesive members joining said first abrasive member to said first major surface of said foam member, and a second adhesive members joining said second abrasive member to said second major surface of said foam member;   said first and second adhesive members being substantially porous to permit liquid to penetrate from said foam member to said first and second abrasive members;
