MYK LATICRETE 345 SUPER FLEX HIGHLY DEFORMABLE TILE ADHESIVE

About MYK LATICRETE 345 SUPER FLEX HIGHLY DEFORMABLE TILE ADHESIVE

•  91 000 74051 Its a polymer-modified tile adhesive (cementitious mortar), designed to fix tiles or natural stone on floors and walls both interior and exterior. 

• Its especially suited for large-format tiles, heavy tiles, porcelain, natural stone, and even tile-on-tile applications. 

Key Features & Benefits

• Highly deformable / flexible: can absorb structural movements or thermal expansions without cracking useful in buildings where there may be shifts or vibrations. 

• Strong bond strength: good shear and tensile adhesion, ensuring tiles stay fixed firmly even on demanding surfaces. 

• Versatile surfaces: works over concrete, cement mortar, plaster, existing tile/stone surfaces, etc. Thin-bed to medium-bed applications: you can apply from thin to modest bed thickness (typical up to ~15 mm). 

• Usable in wet areas: suitable for bathrooms, balconies, even swimming-pool areas (for appropriate tiles/stones), since it has good water- and moisture-resistance once cured.

Typical Use Cases

• Laying ceramic, vitrified, or porcelain tiles  on floors or walls.

• Installing natural stone tiles or large-format tiles (where regular thin-set mortars may crack).

• Renovation work where you may want to tile over existing tiles or stones.

• Wet-area flooring/walls (bathrooms, balconies, terraces) or high-traffic areas (lobbies, kitchens, external facades) because of its strong adhesion and flexibility

Exceptional Flexibility and Bond Strength

MYK LATICRETE 345 SUPER FLEX is formulated with advanced polymer technology to achieve high deformability and superior bond strength. It absorbs minor movements, making it ideal for areas with regular vibrations or thermal variations, such as high-traffic floors and external facades. Its S2 rating certifies its ability to withstand demanding conditions without compromising tile fix integrity.


Versatile Substrate Compatibility

This adhesive provides robust adhesion on a variety of substrates, including concrete, cement plaster, tile, stone, cement boards, plywood, and gypsum boards. It's especially effective for challenging or flexible surfaces, ensuring tiles and stones remain securely fixed across both vertical and horizontal applications in internal and external environments.


Convenient Application and Extended Working Time

The product offers a practical pot life of 4 hours at 27C and an open time of at least 30 minutes, allowing for efficient and flexible application. Its fine powder consistency mixes smoothly with water, and its coverage of 1.2-1.5 kg/m2 per mm ensures economical use. The adhesive is easy to apply using a notched trowel, making it user-friendly for professionals.
