Product Description

It is formulated to: Guarantee perfect adhesion to the substrate and to the reinforcing rods without producing cracks between the reconstructed and existing parts To guarantee thermal compatibility to freeze-thaw cycles by passing the tests required by law To create, after curing, an alkaline environment to protect the reinforcing rods from oxidation Have a low water permeability as protection from the aggression of atmospheric pollutants. Restoration of deteriorated reinforced concrete structures, after checking the compatibility of the resistance class of the supporting concrete. Possible applications: Volumetric reconstruction of the concrete cover of non-structural elements damaged by oxidation of the bars such as front edges, cornices, moldings Regularization and surface fillings in localized reinforced concrete, created by removing gravel nests, spacer bars, anchor holes, outcropping irons ... Surface filler of traces for electrical conduits, pipes, systems in general Restoration and regularization of facade elements such as stringcourses, façade interventions, decorative elements ... Regularization and surface filling of prefabricated structures. Do not apply on: gypsum surfaces Painted surfaces Weak or inconsistent substrates Cellular concrete blocks Wood-cement panels Large surfaces 5 kg bag: 0.3 m2 per cm of thickness Application characteristics in place Mixing water: 18-20% Setting end time at 5 ° C: 30 min Setting start time at 30 ° C: 10 min Setting start time at 22 ° C: 12 min End setting time at 22 ° C: 15 min Pot-life: 8 min Waiting time for painting: 4 hours Waiting time for overcoating with ceramic applied to glue: 8 hours Minimum thickness: 2 mm Maximum thickness per coat: 5 cm Maximum total thickness: 8-10 cm Preparation of the substrates The substrate must be healthy, cohesive, free of dust and any inconsistent or detaching part. Completely free the oxidized armatures, eliminating the rust from the irons with a wire brush or sandblasting. Moisten the substrate. Treatment of the reinforcements: treat the irons with weber.tec fer passivating grout spread in two coats. Restore with webertec repairarapido20 with hardened passivating grout. Product mixing: mix one bag with 4.5 - 5 liters (18 - 20%) of clean water. (2 minutes mixing time)
