Preparation of substrates
Irregular substrates must be levelled before laying the Idrobuild Tex reinforced anti-cracking sheet, for example using a self-levelling product such as Keratech® Eco R30 or a thixotropic levelling product such as Keralevel® Eco LR. Absorbent substrates must first be treated with Primer A Eco, while non-absorbent substrates must be treated with Keragrip Eco.
Anti-cracking for ceramics tiles and natural stone: On the prepared substrate apply, with a 4–6 mm toothed spreader, an adhesive from the H40® Eco range. Then apply Idrobuild Tex on the still fresh adhesive, spreading it out without any creases while pressing it. When more than one sheet has to be laid, always allow for an overlap of 5 cm. The elastic joints in the building structure must also be repeated in the surface coating. Perimeter and fractionising joints must be incorporated for surface coatings. Lay the surface coating, making sure the back of the tiles is fully dampened using an adhesive from the H40® Eco range, with a toothed spreader suited to the size. It is not necessary to apply a coat of primer before laying. Anti-cracking for hardwood floors (with tongue and groove): The substrate must correspond to the requirements of DIN 18356, laying of hardwood floors. For bonding the anti-cracking sheet, hardwood floor adhesives Slc® Eco L34, Slc® Eco L34 Neutra, Slc® Eco L34 Rapid, Slc® Eco L34 Plus or Slc® Eco L34 Flex must be used. Before final gluing of hardwood floors allow a drying time of at least 24 hrs.
