Abstract

A method of forming a dry floor assembly includes cleaning an upper layer with methyl ethyl ketone (MEK) prior to bonding the upper layer to a carbon wicking layer. Said cleaning removes release agent from the upper layer. The method also includes bonding the upper layer to the carbon wicking layer after said cleaning.

First claim

1 . A method of forming a dry floor assembly, the method comprising:
cleaning an upper layer with methyl ethyl ketone (MEK) prior to bonding the upper layer to a carbon wicking layer, wherein said cleaning removes release agent from the upper layer; and bonding the upper layer to the carbon wicking layer after said cleaning.

2 . The method of claim 1 , wherein said cleaning comprises using one or more brushes to wash the upper layer with the MEK.

3 . The method of claim 1 , further comprising washing the upper layer with one or both of water or detergent after said cleaning the upper layer with the MEK.

4 . The method of claim 3 , wherein said washing the upper layer with one or both of the water or the detergent comprises using one or more brushes to wash the upper layer with the one or both of the water or the detergent.

5 . The method of claim 3 , further comprising rinsing the upper layer with water after said cleaning the upper layer with the NIKE MEK and said washing the upper layer with the one or both of the water or the detergent.

6 . The method of claim 1 , further comprising pre-washing the carbon wicking layer with water before said bonding the upper layer to the carbon wicking layer, wherein said pre-washing removes excess polyvinyl acetate (PVA) from the carbon wicking layer.

7 . The method of claim 1 , further comprising:
priming only a first surface of a lower support layer, wherein a second surface opposite from the first surface is unprimed; and bonding the first surface of the lower support layer to the carbon wicking layer.

8 . The method of claim 7 , wherein the lower support layer is formed of steel.

9 . The method of claim 1 , wherein the upper layer comprises a urethane grid.

10 . A method of forming a dry floor assembly, the method comprising:
cleaning an upper layer with methyl ethyl ketone (MEK) prior to bonding the upper layer to a carbon wicking layer, wherein said cleaning removes release agent from the upper layer; washing the upper layer with one or both of water or detergent after said cleaning the upper layer with the MEK; rinsing the upper layer with water after said cleaning the upper layer with the MEK and said washing the upper layer with the one or both of the water or the detergent; and bonding the upper layer to the carbon wicking layer after said cleaning, said washing, and said rinsing.

11 . The method of claim 10 , wherein said cleaning comprises using one or more brushes to wash the upper layer with the MEK.

12 . The method of claim 10 , wherein said washing the upper layer with one or both of the water or the detergent comprises using one or more brushes to wash the upper layer with the one or both of the water or the detergent.

13 . The method of claim 10 , further comprising pre-washing the carbon wicking layer with water before said bonding the upper layer to the carbon wicking layer, wherein said pre-washing removes excess polyvinyl acetate (PVA) from the carbon wicking layer.

14 . The method of claim 10 , further comprising:
priming only a first surface of a lower support layer, wherein a second surface opposite from the first surface is unprimed; and bonding the first surface of the lower support layer to the carbon wicking layer.

15 . The method of claim 10 , wherein the lower support layer is formed of steel.

16 . The method of claim 10 , wherein the upper layer comprises a urethane grid.

17 . A method of forming a dry floor assembly, the method comprising:
cleaning an upper layer with methyl ethyl ketone (MEK) prior to bonding the upper layer to a carbon wicking layer, wherein said cleaning removes release agent from the upper layer, and wherein said cleaning comprises using one or more brushes to wash the upper layer with the MEK; washing the upper layer with one or both of water or detergent after said cleaning the upper layer with the MEK, wherein said washing the upper layer with one or both of the water or the detergent comprises using the one or more brushes to wash the upper layer with the one or both of the water or the detergent; rinsing the upper layer with water after said cleaning the upper layer with the MEK and said washing the upper layer with the one or both of the water or the detergent; pre-washing the carbon wicking layer with water before said bonding the upper layer to the carbon wicking layer, wherein said pre-washing removes excess polyvinyl acetate (PVA) from the carbon wicking layer; bonding the upper layer to the carbon wicking layer after said cleaning, said washing, said rinsing, and said pre-washing; and priming only a first surface of a lower support layer, wherein a second surface opposite from the first surface is unprimed.

18 . The method of claim 17 , further comprising bonding the first surface of the lower support layer to the carbon wicking layer.

19 . The method of claim 18 , wherein the lower support layer is formed of steel.

20 . The method of claim 19 , wherein the upper layer comprises a urethane grid.
