EN 12004 MONOFLEX-XL Cement-based adhesive with increased performance for the installation of tiles in interior and exterior areas
26/16
Areas of application: • MONOFLEX-XL is a flexible adhesive for the thin-bed installation of large format earthenware, vitrified and fully vitrified tiles/slabs as well as other ceramic finishes, mosaics and natural stone, which is neither sensitive to discolouration nor is translucent. • MONOFLEX-XL is suited for tiling to all substrates in accordance with DIN 18157, part 1, e.g. concrete, aerated concrete, plaster/render, cement-based and calcium sulphate based heated and unheated (flow) screeds, masonry work, moisture resistant plasterboard and gypsum fibre boards, composite materials in expanded or extruded polystyrene with a mortar coating and reinforcement layer embedded, etc. • For tiling over mineral-based or dispersion-based SCHOMBURG bonded waterproof membranes.

Product application: Mix MONOFLEX-XL with clean water in a clean mixing bucket until homogenous. Mix ratio: 9.2–11.00 litres water : 25 kg MONOFLEX-XL. Allow to stand for approx. 3 minutes then remix. Do not prepare more adhesive than can be used within the pot life. Spread the mixed adhesive over the substrate surface and comb through with a notched trowel suitable for the tile format. Install tiles within the adhesive open time.
When installing large format tiles greater than 60 x 60 cm, we recommend that MONOFLEX-XL is modified with UNIFLEX®-B. Modifying with UNIFLEX®-B elastifier increases the deformability and adhesion strength of MONOFLEX-XL. Dependent on the modification, deformability class S2 can be achieved, which is particularly recommended for tiles larger than 60 x 60 cm. This considerably compensates for shear stresses, which can lead to delamination in unfavourable exterior conditions. UNIFLEX®-B is mixed with water for improved application and then mixed with MONOFLEX-XL until homogenous.
Properties: • Extremely good slump resistance with the best application properties • Long open time • Easy application • For large format tiles and porcelain • For heated screeds • For interior and exterior use • Tested in accordance with DIN EN 12004 C2 TE DIN EN 12002 S1
Mixing ratio: highly deformable (relates to class C2 S2, deformation > 5 mm):
Application: The substrate must be dry, load-bearing, adequately flat, free from penetrating cracks and free from separating substances such as oil, paint, laitance and loose parts. They must have a largely closed surface with a surface strength and condition commensurate with their type. When installing tiles, the substrate, substrate preparation and product application must conform to DIN 18157, part 1. Prime porous substrates with ASO®-Unigrund. Heated floors are to be heated prior to installing tiles. The readiness of a substrate to receive finishes is to be determined by the carbide (CM) method and may not fall below the following values:
