TherGlass Concrete REPAIR FAST H TX

Specifications and application form

Support Preparation

• The support must be strong and stable, free of dust, paint, oil, grease, etc. To do this, it must be cleaned, removing any dust, liquids, flaking, efflorescence residue, and any other substance that could impair good adhesion to the support.
• Damaged concrete areas must be removed to a strong, sound surface; the edges of the repair must be mechanically cut to a depth of at least 4 mm.
• If there are reinforcements affected by corrosion, these will be uncovered until the exposed reinforcement is no longer affected.
• Remove rust from the reinforcements and clean mechanically to a minimum level of Sa2.
• It is recommended to clean with sandblasting, steel bristle brush, mechanical brushing with a needle gun, etc.
• The substrate must be moistened to saturation, without flooding, before applying the mortar.
• To improve adhesion, you can use the Pregunite Pro bonding bridge (in this case, do not wet the substrate).
