Tinted Spray Buff and Tiecoat for Hardwood Floor Refinishing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hard-surfaced floors, such as hardwood, exhibit dull, faded, and scratched appearances due to wear, particularly in high-traffic areas, with existing clear coatings like spray buff and tiecoat failing to effectively conceal white scratches and adhere to cross-linked topcoats.
Innovation Solution
A tinted coating comprising a base component and colorants like tints, dyes, or pigments is applied to the topcoat of hard-surfaced floors, matching the floor's color to significantly reduce the appearance of scratches and enhance gloss levels, using either a tinted spray buff for localized application or a tinted tiecoat for full refinishing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a clear spray buff is applied to the hard-surfaced floor, then the gloss level is increased and the dull appearance is reduced, but the scratches remain visible and the faded appearance is not corrected
Solution Approach 1:
The patent applies colorants (tints, dyes, or pigments) to the spray buff formulation to match the color of the hard-surfaced floor. This color matching allows the coating to visually blend with the floor surface, thereby concealing scratches and faded areas while maintaining the gloss-enhancing properties of the clear acrylic base.
2Reliability
If a clear tiecoat is applied to the hard-surfaced floor, then the entire floor can be refinished and adheres to the topcoat, but it cannot effectively adhere to cross-linked, densely cross-linked, or radiation cross-linked topcoats and scratches remain visible
Solution Approach 1:
The tiecoat is formulated with colorants that match the color of the hard-surfaced floor. This color matching enables the tiecoat to conceal scratches and visual defects in the floor surface while maintaining its adhesion properties to the topcoat and underlying layers.
3Object-generated harmful factors
If the entire hard-surfaced floor is refinished using a tiecoat, then the scratched appearance is reduced and the floor is prepared for a new topcoat, but the process requires intensive cleaning, rinsing, and multiple steps
Solution Approach 1:
The patent combines multiple functions into a single coating product: the tinted spray buff or tiecoat simultaneously provides scratch concealment through color matching, surface conditioning, and preparation for topcoat application. This consolidation eliminates the need for separate intensive cleaning and multiple refinishing steps, simplifying the overall process.

AI summary
A tinted coating for a hard-surfaced floor, such as a hardwood floor, includes a base component and at least one colorant. The base component comprises an acrylic polymer and water, and the colorant is selected from the group consisting of a tint, a dye, and a pigment. The tinted coating is either a tinted tiecoat or a tinted spray buff. The tinted coating is used to improve the appearance of the hard-surfaced floor.
