Free Site Survey & Colour Consultation
We assess your window frame condition, material, and advise on the correct Kolorbond product for your project and discuss your chosen colour.
Silicone Removal
All existing silicone beads around the window frames are carefully removed before preparation begins — critical for achieving a clean, precise edge line.
Kolorbond WindowPrep Application
All UPVC frame surfaces are wiped thoroughly with Kolorbond WindowPrep, removing all grease, silicone residue, oxidisation, and contamination.
Mechanical Abrading
All prepared surfaces are lightly abraded with Mirka Mirlon red scotch-brite pads to create a consistent mechanical key across all frame profiles.
Masking & Protection
All glazing, brickwork, sills, and surrounding surfaces are fully protected with masking paper and professional tape.
Mist Coat
A fine, diluted mist coat of Kolorbond is applied first — providing an initial adhesion layer and revealing any remaining surface contamination.
Full Coat Application (Minimum 3 Coats)
A minimum of three full coats of the specified Kolorbond product are applied using professional HVLP spray equipment.
Silicone Resealing & Final Inspection
Fresh silicone is applied in your chosen RAL-matched colour. All masking is removed and a full quality inspection completed.
