Interior Surface Reconditioning Coating System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Commercial and industrial facilities, particularly those processing food, face frequent surface deterioration due to hot water and detergent cleaning, leading to issues like cracking paint, rust, corrosion, and water trapping, necessitating a more durable reconditioning method that doesn't disrupt operations.
Innovation Solution
A method involving surface preparation, application of layers to create a smooth, continuous, and impervious barrier against moisture and air intrusion, using expandable foam to fill gaps, putty for smoothing, and polymeric coatings to enhance structural strength and prevent corrosion, allowing for quick reconditioning without production shutdowns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional painting is used for reconditioning, then the facility can be reconditioned with simple and traditional methods, but the surface durability is insufficient and requires frequent reconditioning
Solution Approach 1:
The patent applies a composite coating system consisting of multiple layers including a primer, an intermediate coating layer, and a top coat. Each layer serves a specific function: the primer adheres to the substrate, the intermediate layer provides bulk and flexibility, and the top coat provides chemical resistance and durability. This composite structure significantly improves surface durability compared to traditional single-coat painting, while still maintaining relatively simple application procedures.
2Reliability
If complete reconditioning is performed, then the facility surfaces can be restored to optimal condition, but production operations must be shut down for extended periods
Solution Approach 1:
The reconditioning process is segmented into multiple thin coating layers applied in sequence rather than requiring removal and replacement of entire surface materials. The primer, intermediate coating, and top coat are applied in separate stages, allowing for a more efficient reconditioning process that minimizes downtime. This segmented approach enables facilities to maintain operations while still achieving comprehensive surface restoration.
3Object-generated harmful factors
If hot water and detergent cleaning is used frequently, then bacteria and grease can be killed and emulsified, but the paint finish deteriorates through cracking, peeling, and chipping
Solution Approach 1:
The coating system is designed with specific chemical parameters to resist degradation from hot water and detergent cleaning. The intermediate coating layer and top coat contain chemicals that provide resistance to thermal stress from hot water and chemical stress from chlorine-containing detergents. This parameter optimization allows the surface to withstand frequent cleaning without the paint finish cracking, peeling, or chipping.
4Loss of time
If simple painting is applied, then reconditioning can be completed quickly, but the surface becomes impervious to water and chemicals only temporarily
Solution Approach 1:
The multi-layer composite coating system provides long-lasting water and chemical resistance. The primer creates a bonded base layer, the intermediate coating provides bulk and flexibility that maintains adhesion over time, and the top coat provides the primary chemical and water resistance. This composite structure ensures that the protective barrier remains effective for extended periods, far exceeding the durability of simple single-coat painting.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The method significantly extends the interval between reconditioning needs by creating a durable, water-resistant surface that withstands frequent cleaning and UV exposure, preventing rot and corrosion, while maintaining operational continuity.
Implementation Method 1
gaps and holes are filled with expandable plastic foam and then sculpted to transition smoothly to surrounding surfaces
Implementation Method 2
layers are applied to an interior surface in such a way that they bind together and result in a new surface that is a highly impervious barrier to moisture
Implementation Method 3
This more robust surface sheds water quickly and will resist the penetration of oft-applied water

AI summary
A method and composition for reconditioning the inner surfaces of a facility. After removing loose material, corrosion and rust by abrading the surface, repairs are made to the surface. Gaps, cracks, and pits are filled and transitions from one surface material to another are smoothed with putties; holes and complex areas of the surface are filled with expanding foams and shaped to contour; and sheet metal is added where corrosion and rust have left extensive weakened areas in the surface. A corrosion inhibitor such as aluminum flakes or micaceous iron oxide is applied to the shaped surface followed by a structural coating of polyurea or elastomeric urethane and top coat of moisture cured urethane or polyaspartic acid that adds an additional water barrier and increases that surface shaping to shed water. The combination of these layers results in a surface with improved robustness against frequent cleaning.
