T 480

Instructions for use

Preparation for use
Substrates to be covered must be sufficiently dry, solid and regular, clean and sound, free of oil and grease, dust, crumbly material and dirt in general, and free of residues of paint film, and must be suitably cured and free of significant shrinkage. Indicatively, traditional cementbased screeds with normal setting and hardening must be cured for at least 28 days; cement-based or cement-lime mortar based plasters must dry for at least 14 days. Large imperfections and surface irregularities such as unevenness, cavities, gravel nests, eroded or deteriorated points, must be previously repaired and uniformed with self-levelling smoothing, for example Livellina 0-10, or with a specific skimming product, such as Multimix Evo or Rinnova. Particularly porous and crumbling substrates must be previously consolidated with Tile Primer.

Product preparation
Mix T 480 with 29-31% of clean water (equal to 7.25 – 7.75 litres per 25 kg bag) in the following way: in a special container pour almost all the necessary water, then add the powder product slowly, stirring at the same time while the mixture is forming using a low-speed drill with a specific propeller. Once all the powder has been added, pour in the remaining water and stir until the mixture is homogeneous and free of lumps, taking particular care to remove lumps of unmixed material from the walls and bottom of the container. Allow to stand for approx. 5 minutes, then mix briefly. The prepared adhesive remains workable in the mixing containers for about 5 hours under normal conditions (at 20 °C); higher temperatures shorten the workability time, while lower temperatures lengthen it.

Storage

Store T 480 in a dry and sheltered place. In the original closed bags it is kept for at least 12 months. PROTECT FROM HUMIDITY.
