Area of use

Use:

Laying of ceramic tiles, homogeneous tiles, large-size slabs, glass mosaic, dimensionally and colour stable natural stone coverings of all types and formats, on flooring and walls. For domestic, commercial and industrial applications; in areas that are permanently damp and subject to thermal shock and freezing.

Suitable for:

– Cement-based plasters, lime and cement
– Mineral screeds made using hydraulic binders such as Keracem® Eco
– Cement-based levelling and self-levelling products
– Concrete and cellular concrete
– Existing flooring and walls with glazed tiles, cement-based and resin paving, homogeneous tiles
– Underfloor heating systems
– Cement and synthetic resin-based waterproofing products
– Cast asphalt screeds.

Suitable for gypsum-based plasters and anhydrite-based screeds, gypsum-based levelling and self-levelling products, after application of the eco-friendly water-based surface isolation product Primer A Eco.

Do not use:

Do not use on plastic or resilient materials, metals, wood and on substrates subject to continuous moisture rising.

Instructions for use

Preparation of substrates:

Substrates must comply with BS 5385, parts 1-5, be compact, free from substances that reduce adhesion such as dust, oil, grease and with no loose material. The substrate must be stable, non-deformable, without cracks and have already completed the curing period of hygrometric shrinkage. Uneven sections must be corrected with suitable smoothing and finishing products such as Keralevel® Eco LR or Keratech® Eco R30. Anhydrite screeds must have a damp content of ≤ 0.5 CM-% and be adequately sanded, cleaned using a suitable vacuum cleaner and primed with Primer A Eco. Cement-based screeds must be cured for at least 28 days and have a residual humidity ≤ 2 CM-%. Can be laid on mineral screeds prepared using the eco-friendly binder Keracem® Eco after only 24 hrs (≤3 CM-%). When laying on screeds containing heating systems, follow the instructions given in the BS 8204 used to test the heating system itself. When under floor heating has been used the residual humidity of anhydrite screeds must be ≤ 0.3 CM-%, whereas that of cement screeds must be ≤ 2 CM-%. Cast asphalt screeds with well-bonded sand must be cleaned by vacuuming off the excess sand before laying.

Instruction for use:

Prepare H40® Eco Flex in a clean container, first of all pouring in a quantity of water equal to approximately ¾ of the amount required. Gradually pour the powder into the container, mixing the paste from the bottom upwards with a low-rev (400/min.) electrical mixer. Add more water until the desired consistency is obtained. The mixture must be of smooth consistency and without any lumps. Apply a contact layer of adhesive using the smooth part of the notched trowel. Then apply the adhesive with a suitable, notched trowel for the type and dimensions most appropriate for the format and type of tiles to be used. In environments subject to heavy traffic and in external locations, use the back buttering technique.

Tools:

Mixing agitators, toothed spreaders suitable for the formats and types of tiles to be used. Wash tools with water before the product hardens.
