METHOD AND SYSTEM FOR THE SELECTIVE COATING OF AN INTERIOR SURFACE

摘要

The present disclosure relates, in various embodiments, to methods and systems for masking and de-masking a portion of an interior surface of a structure, such as may be useful in the selective coating of an interior surface of a structure. The method comprises providing a masking device comprising a magnetically active material and a seal-forming material and inserting the masking device into an interior of the structure. A magnetic force is activated in order to bring the masking device into sealable contact with a portion of an interior surface of the structure, thereby producing a masked portion of the interior surface. While maintaining the sealable contact, the unmasked portion of the interior surface of the structure is coated with a coating material. After the coating, the magnetic force is deactivated in order to bring the masking device out of sealable contact with the interior surface of the structure.

主权项

1. A system for masking and de-masking a portion of an interior surface of a structure comprising:
(a) a masking unit comprising at least a body and a handle, the body comprising
(i) a magnetically active material, and(ii) a seal-forming material; and (b) an object that is capable of producing a magnetic force that acts on an interior cavity of a structure; wherein the masking unit is capable of being inserted into the interior cavity of the structure; and wherein the magnetic force is capable of causing the masking unit to sealably contact a portion of an interior surface of the structure.
