Product description
-
STEIN TEC® Bond Adhesive "Haftfix" is a hydraulically binding, polymer-modified, highly processed adhesive bonding mortar with application-specific mineral and organic additives. STEIN TEC® Bond Adhesive "Haftfix" is available as bag ware. It is especially designed to increase the adhesive tensile strength of slabbed surfaces as well as of element surfaces with high load requirements, in general. “Haftfix” can also be used to improve the adhesive bond of bedding mortar on e.g. concrete foundations or concrete ceilings etc. (if applicable, consider water permeability!).
Using STEIN TEC® Bond Adhesive "Haftfix", the adhesive tensile strength of the composite zone between surface and bedding is increased multiplicatively. High adhesive tensile strength is decisive for the load capacity and the durability of bonded element surfaces. It ensures, that tensions as a result of loads and thermal stress can be transferred evenly to the subsurface, which enables to largely avoid crack formation.
STEIN TEC® Bond Adhesive "Haftfix" is available as bag ware in 25 kg bags.The required layer thickness of the bond adhesive is approx. 2 to 2,5 mm, which equates to a consumption of approx. 2 kg per m2.

Important information
If concrete blocks, slabs and, in general, elements with smooth and even (e.g sawn) underneaths are used, STEIN TEC® Bond Adhesive Haftfix should be applied additionally.
Paving blocks, slabs and contact surfaces that shall be treated with "Haftfix", must be clean, i.e. free from dust, grease, oil, adhesions and impurities (e.g. cutting or grinding slurry). If bond adhesive should get onto the surface of elements, these must be replaced. Complete removing of bond adhesive residues is hardly possible.
Suitability for storage 3 months in dry cool rooms.
Processing/building-in
-
STEIN TEC® Bond Adhesive "Haftfix" shall be mixed only with clear cold water (added amount see Technical Bulletin or imprint on bag), either by a stirring device or in the positive mixer, free of lumps. Stir up intensively again after 3 minutes of “maturing time”. Pot life approx. 60 minutes at 20° C.
The processing takes place "Fresh-in-Fresh" by dipping the elements underneath/contact surface into the bond adhesive, immediately before the laying. If dipping is not possible, apply bond adhesive by a broad brush or a stiff scrubber onto the clean elements underneath.
