Mapei Kerapoxy Adhesive is a two-component epoxy tile adhesive developed for installations where a conventional cement-based adhesive may not provide the chemical resistance or bonding performance required. Its thixotropic, no-vertical-slip consistency helps hold ceramic, porcelain and suitable stone in position while installing on walls, floors and demanding tiled surfaces.
Classified R2T, this reactive-resin adhesive is a specialist choice for suitable industrial and wet-area installations, including approved swimming-pool applications. It is particularly useful for securely fixing shaped tile pieces and details where a strong, rigid bond is needed. It is an adhesive first: choose it to bond tiles, not simply because the project needs an epoxy grout.
A deformable cementitious adhesive such as Keraflex Maxi S1 is often the more practical option for ordinary large-format tile work. Kerapoxy Adhesive is designed for projects that specifically benefit from a reactive epoxy bond, resistance to demanding service conditions and reduced slip on vertical surfaces.
If the main requirement is colour-matched, easy-clean epoxy tile joints, compare Kerapoxy Easy Design instead.
Both components must be mixed thoroughly in the prescribed ratio, with the substrate clean, sound, suitably prepared and compatible with the system. Working time is limited once mixed, so prepare the installation before opening the pack. This is a rigid tile adhesive, not a flexible sealant or a product for filling movement joints. Confirm the requirements for immersion, chemical exposure and unusual substrates before selecting it.
