Abstract

An assembly for removing a desired portion of one or more layers of paint or another coating from a designated area is provided including a pad soaked with a chemical paint remover and an adhesive layer arranged about the pad configured to couple the assembly to the designated area. A removable first protective layer is positioned upwardly adjacent and is coupled to the adhesive layer. A flexible support layer is positioned adjacent the adhesive layer and the pad, opposite the removable first protective layer. A heat pad is arranged downwardly adjacent the flexible support layer. The heat pad is configured to control a microclimate adjacent the assembly when activated. A removable second protective layer is coupled to a surface of the heat pad. Removal of the second protective layer activates the heat pad.

First claim

What is claimed is:

1. An assembly for removing a one or more layers of paint or another coating from a designated area, comprising:
a pad soaked with a chemical paint remover;
an adhesive layer arranged about a periphery of the pad configured to couple the assembly to the designated area;
a removable first protective layer positioned adjacent and coupled to a first surface of the adhesive layer;
a flexible support layer positioned adjacent a second surface of the adhesive layer and the pad, opposite the removable first protective layer;
a heat pad arranged adjacent a surface of the flexible support layer, the heat pad being configured to control a microclimate adjacent the assembly when activated; and
a removable second protective layer coupled to a surface of the heat pad, wherein removal of the second protective layer activates the heat pad.

2. The assembly according to claim 1 , wherein the chemical paint remover has a hazardous air pollutant (HAP) free chemical composition.

3. The assembly according to claim 1 , wherein at least one of a size and shape of the pad is generally complementary to the designated area.

4. The assembly according to claim 1 , wherein at least one of a size and shape of the heat pad is generally complementary to the pad soaked with chemical paint remover.

5. The assembly according to claim 1 , wherein an exothermic chemical reaction in the heat pad is activated in response to contact with air.

6. The assembly according to claim 1 , wherein the microclimate includes a local temperature and moisture level.

7. The assembly according to claim 1 , wherein a first surface of the adhesive layer includes an adhesive material.

8. The assembly according to claim 7 , wherein the adhesive material is configured to retain the first protective layer within the assembly.
