Project Overview:
Royal Group Central Tower is a landmark Grade-A commercial skyscraper situated in the heart of Phnom Penh's financial district, recognized by its sweeping glass-curtain architecture and modern corporate interiors. High-rise corporate headquarters require versatile coating specifications: exterior concrete transitions must resist aggressive tropical weathering, interior executive spaces demand washable, low-sheen aesthetics, and architectural metal components require durable industrial protection. Kontech supplied an integrated Jotun coating package supporting both external envelope contractors and specialized interior fit-out teams.
Short Summary:
PComplete architectural and protective coating supply by Kontech to the painting and interior fit-out contractors for Royal Group Central Tower. The supplied Jotun specification pairs exterior weatherproofing (Jotashield Primer and Jotashield Antifade Colours) with high-durability interior finishes (Essence Easy Primer, Essence Pro Matt, and Essence Easy Clean Matt). For specialized metal applications, Conseal Touch-Up (TU) was utilized on the unique interior undulated curtain wall features, while Jotamastic 90 epoxy and Hardtop XP polyurethane protect exterior steel railings and architectural metals.
Application Area:
Exterior Concrete Elements, Undulated Interior Fluted Curtain Walls, Commercial Office Walls & Ceilings, and Steel Railings/Metals
Coating System Specification:
1. Architectural Exterior Weather Barrier (Jotun):
Surface Preparation & Putty: Jotun Interior & Exterior Putty
Used to fill hairline cracks, level surface imperfections, and smooth rendered concrete substrates before primer application.
Masonry Penetrating Primer: Jotashield Primer
An acrylic waterborne primer that penetrates concrete substrates, providing strong alkaline and efflorescence resistance to stop moisture migration behind exterior paint films.
Exterior Finish: Jotashield Antifade Colours
Formulated with advanced UV-protected pigments to guard exterior parapets, podium structures, and concrete transitions against solar heat bleaching, dirt pickup, and monsoon rains.
2. High-Grade Interior Commercial Fit-Out (Jotun):
Interior Wall Primer: Essence Easy Primer
Delivers high substrate opacity and reliable adhesion across plastered drywall partitions and interior masonry.
Interior Wall Topcoats: Essence Easy Clean Matt & Essence Pro Matt
Premium washable emulsions engineered for active office corridors and administrative suites. Delivers a smooth, non-reflective matt finish that enables quick wipe-down of fingerprints, smudges, and dirt marks without film degradation.
3. Specialized Architectural Metalwork & Industrial Systems (Jotun):
Undulated Curtain Wall Panels: Conseal Touch-Up (Conseal TU)
A single-pack, high-build acrylic direct-to-metal (DTM) coating applied to the interior textured/undulated fluted curtain wall assemblies. Provides fast recoat windows, flexible adhesion, and a smooth protective finish.
Steel Railings & Architectural Metalwork: Jotamastic 90 & Hardtop XP
A two-pack heavy-duty protective system: surface-tolerant Jotamastic 90 epoxy mastic provides an impenetrable anti-corrosion barrier, topped with Hardtop XP aliphatic polyurethane for non-yellowing UV durability, gloss retention, and impact resistance across exterior handrails and exposed metals.
