Concrete Repair

Builda Finish-300

Single component polymer modified cementitious fairing coat (0.5-3.0mm)

Single-component polymer modified repair mortar used as a fairing coat or smoothing mortar for concrete surfaces.

  • Ready to use after mixing with water
  • Low shrinkage and crack-free curing
  • Polymer modified with low permeability
  • Good adhesion and recoatable

Surface Preparation

Cementitious surfaces should be sound, clean, uncontaminated and free of loose materials. Soak the substrate with water to saturated surface dry condition

Void Filling

Deeper voids should be filled before application by reducing the mixing water to produce a trowelable mortar

Mixing

Add one 20 kg bag slowly to 6.5-7.0 L clean cold water and mix for 3-4 minutes at 400-500 rpm until smooth and lump-free

Application

Apply the mixed material as a thin fairing or smoothing coat using suitable tools over horizontal, vertical or overhead surfaces

Important Note

Do not exceed the recommended water dosage and do not re-temper with extra water after mixing

  • Fairing or skim coat on concrete and mortar substrates
  • Cosmetic repair fairing coat after major concrete repair
  • Filling slight honeycombing and blowholes
  • Very thin render coat for internal and external finishing
  • Preparatory treatment before thin film protective coatings
