Render & Coating Renewal
When render cracks or coatings delaminate, the façade loses its protective skin. We remove failed layers, repair substrates, and apply new render or coatings that keep water out while letting the building breathe — protecting performance and presentation for years ahead.

Render systems are one of the most common finishes for façades across Sydney. Over time, however, they become vulnerable to cracking, delamination, water ingress, and staining. These aren’t simply visual defects — once cracks form, they create a pathway for water to penetrate, leading to concrete spalling, rusting reinforcement, and serious structural issues beneath the surface.

Our render and coating renewal service is designed to rebuild the façade envelope so it performs as both a protective and aesthetic barrier. We approach each project by addressing not only the visible surface, but also the condition of the substrate beneath.

Our Process

  1. Inspection & Diagnosis
  2. We assess cracks, hollow drummy render, staining, and water entry points. Thermal imaging and moisture meters may be used to locate hidden failures.
  3. Substrate Preparation
  4. Loose render is removed back to a sound base. Exposed concrete or brickwork is repaired, ensuring the new render bonds effectively.
  5. Re-rendering
  6. Using high-performance mixes matched to the building’s substrate (cementitious, polymer-modified, or lime-based for heritage), we apply new layers with strict thickness control to avoid future delamination.
  7. Movement & Control Joints
  8. Where cracking is linked to structural movement, new control joints are introduced to relieve stress and prevent repeat cracking.
  9. Protective Coatings
  10. The façade is sealed with breathable, elastomeric, or anti-carbonation coatings depending on the building’s needs. These protect against UV, moisture, and pollution while improving appearance.
  11. Final QA & Finish
  12. Every elevation is visually assessed for uniformity, adhesion, and protective performance before sign-off.

Key Considerations

  • Compatibility – Incorrect mixes can cause debonding, shrinkage, or accelerated failure.
  • Weather Dependence – Application must occur under suitable conditions to ensure curing and adhesion.
  • Aesthetics – Coating systems affect colour, texture, and sheen — critical for high-value properties.

Value to the Client

  • Stops moisture ingress and protects structure.
  • Enhances appearance with a fresh, uniform finish.
  • Extends façade life by shielding against pollutants and UV.
  • Prevents expensive structural damage hidden beneath render.
  • Restores property value by eliminating unsightly cracks and stains.
