Ceramic Tile Floor Release Membrane for Substrate Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for installing ceramic tiles on concrete, wood, or backer board substrates make it difficult to remove and replace tiles without damaging the substrate, particularly hardwood floors, due to the need for strong adhesives that can damage the surface during removal.
Innovation Solution
A method involving the use of loosely laid vinyl tiles or sheets that 'float' on the substrate, allowing ceramic tiles to be easily removed by lifting the vinyl tiles, along with the use of releasable adhesives and membranes that can tear or separate for easy removal without damaging the substrate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional latex-modified thinset mortar is used to bond ceramic tiles to the substrate, then the tiles have sufficient bonding strength and stability, but the tiles become difficult to remove and may damage the substrate during removal
Solution Approach 1:
A release membrane is introduced as an intermediary layer between the ceramic tile and the substrate. The tile bonds to the membrane while the membrane remains unreleasably bonded to the substrate, enabling tile removal without substrate damage. This mediator resolves the contradiction by providing both strong bonding during installation and easy removal later.
Solution Approach 2:
The bonding system is segmented into distinct functional layers: the substrate, the release membrane, and the ceramic tile. This segmentation allows the membrane to serve as a removable interface layer that separates the permanent substrate from the removable tile, solving the contradiction between permanent bonding and easy removal.
2Strength
If backer board is added to strengthen the floor substrate, then the floor can support ceramic tiles without cracking, but the installation complexity and time increase
Solution Approach 1:
The release membrane serves multiple functions simultaneously: it provides a bonding surface for the tile, acts as a release layer for easy removal, and can function as an uncoupling membrane. This multi-functionality reduces the need for additional layers like backer board, simplifying the overall installation while maintaining substrate strength.
3Strength
If backer board is installed on hardwood floors to provide strength, then the floor can accept ceramic tiles, but the hardwood floor may be damaged during backer board attachment
Solution Approach 1:
The release membrane acts as a protective intermediary between the installation process and the hardwood substrate. By bonding the tile to the membrane rather than directly to the hardwood, the membrane protects the hardwood from damage during both installation and future removal, eliminating the need for potentially damaging backer board attachment.
4Ease of operation
If vinyl tiles are laid loosely to float on the substrate, then ceramic tiles can be easily removed by lifting the vinyl, but the floor lacks the rigidity and strength needed to support heavy ceramic tiles
Solution Approach 1:
The release membrane provides a unreleasable bond to the substrate, ensuring the floor maintains its rigidity and strength. The ceramic tile bonds to this stable membrane interface, allowing easy removal by breaking the tile-membrane bond while the membrane remains firmly attached to the substrate, providing both strength and ease of removal.

AI summary
An article for applying to a floor substrate for preparing the floor substrate for laying of ceramic tiles by bonding ceramic tiles to the article. The article comprises a tile backer board for application to a floor substrate and a sheet bonded to the backer board for bonding of ceramic tiles to the sheet. The sheet comprises a plurality of layers bonded together wherein separation of the sheet along layers thereof is effected for removal of laid ceramic tiles from the backer board. Alternatively, the sheet is bonded to a floor substrate, and the ceramic tiles are bonded thereto. Alternatively, the article is a tape with releasable adhesive thereon. The adhesive releasably adheres to the floor substrate, and the ceramic tiles are bonded to the tape. Alternatively, the article comprises sheets which lie on the floor substrate and which float on the floor substrate and to which are bonded the ceramic tiles.
