Flexstrip 120
Fabric-coated waterproof elastic joint sealing tape

Drykos® Flexstrip 120 is a waterproof joint cover tape consisting of an elastomeric core with high deformation capacity, fully coated on both sides with absorbent fabric. The presence of the textile coating allows for excellent impregnation and integration with cementitious waterproofing systems, ensuring high adhesion to the substrate and the creation of a continuous and durable system. Thanks to its high elasticity and ease of application, Drykos® Flexstrip 120 is particularly suitable for sealing and waterproofing joints in surface waterproofing systems.

Application info
Substrate preparation
Application surfaces must be clean, solid, and free of dust, loose parts, oils, or contaminants that could compromise adhesion. The substrate must be thoroughly roughened and prepared to ensure adequate anchoring of the waterproofing system.
Application
Drykos® Flexstrip 120 must be applied in combination with elastic waterproofing mortars such as Drykos® Drylastic or Drykos®Drytop. Proceed by applying a uniform layer of mortar to the substrate, with an adequate thickness and a width greater than that of the tape. The tape is then positioned on the fresh layer and pressed carefully to ensure the complete embedding of the fabric into the applied material. Subsequently, cover the Drykos® Flexstrip 120 tape with a further layer of the same waterproofing product, ensuring the continuity of the system and the complete sealing of the joint.
Other indications
- Apply the product exclusively to adequately prepared substrates.
- Ensure complete impregnation of the fabric into the waterproofing mortar.
- Ensure the continuity of the system through correct overlapping of the tapes.
- Avoid application in unsuitable environmental conditions (frozen surfaces, presence of free water).
