Angkop Corp — For Contractors & Specifiers
The Angkop
Wall System.
2 Steps. Same Day.
Traditional stone installation involves 7 stages, multiple trades, and weeks of lead time. The Angkop Wall System reduces that to 2 steps — no structural reinforcement, no crane, no mason, no cure time. This guide covers the full system: assembly stack, substrates, tools, and what to avoid.
The Assembly Stack
01
How the System Stacks
Every Angkop installation follows the same layered assembly — whether wall, ceiling, dry, or wet. Each layer has a specific role. Get the stack right and the finish is permanent.
Existing ceiling or wall — popcorn, drywall, concrete, masonry. Leave as-is if structurally stable. In many retrofit applications, no scraping or demolition is required.
New substrate board — 1/4" drywall, lightweight cement board, Kerdi-Board, or GoBoard. Screwed directly into joists. Seams must be staggered — do not align substrate joints.
MegaLite adhesive — applied to the panel back with a notched trowel. Permanent high-strength bond for vertical and overhead applications.
Flexible Natural Stone™ — pressed to surface. Layout (stacked, staggered, bookmatched, random) is a design choice.
Specialty adhesives — metal, wood composite & transition applications — Sikaflex®-11 FC for 3D Wood Fence Panels, painted steel cap, aluminium ledge edging, and end terminations. Sikaflex® AT Metal for aluminium-to-steel and metal-to-metal transitions. Remains flexible in freeze-thaw conditions. Suitable for exterior environments. Sika Primer required as dictated by substrate condition.
Critical Detail
02
Why Substrate Seams Must Be Staggered
Flexible stone panels are thin. Aligned substrate seams concentrate movement in a single line — increasing cracking risk and visible lines printing through the stone surface.
Substrate Guide
03
Choosing the Right Board
MegaLite bonds to all standard construction substrates when properly prepared.
Walls — All Environments
Dry Ceilings — Retrofit & New Build
Wet Ceilings — Bathroom, Spa & Hospitality
Cutting Methods
04
Tools & Cutting by Method
Method 01 — Diamond Blade ★ Recommended
Continuous rim porcelain or stone-rated diamond blade on a track saw or angle grinder. Support the sheet fully underneath. Slow feed rate, low-vibration passes.
PPE & Dust Safety
Use a dust mask or respirator, eye protection, and adequate ventilation. Dry cutting generates fine mineral and silica-containing dust.
Pro Installer Kit
Track saw or 4.5" angle grinder with continuous rim diamond blade + offset aviation snips + oscillating multi-tool + fresh sharp blades + long metal straight edge.
Bonding

Adhesive & Application
MegaLite is the recommended adhesive for all Angkop installations — walls, ceilings, wet zones, and over existing surfaces.
Specialty Adhesives — Metal, Wood Composite & Transition Applications
Sikaflex®-11 FC Construction Sealant/Adhesive
Use for: Angkop Original Colour 3D Wood Fence Panels — Flexible Stone on painted steel cap — Aluminium ledge edging — End terminations and transitions.
Advantages: Bonds to properly prepared painted steel — Bonds to aluminium — Bonds to wood-based composite products — Remains flexible in freeze-thaw conditions — Excellent water resistance — Suitable for exterior environments. Sika Primer required as dictated by substrate condition.
Sikaflex® AT Metal
Use for: Aluminium edging to painted steel cap — Metal-to-metal transitions — Exposed edge terminations.
Surface Preparation — Prior to Installation
Lightly abrade glossy painted steel surfaces. Remove all dirt, oxidation, oil, and contaminants. Clean with an approved solvent cleaner. Allow surfaces to dry completely. Apply adhesive according to manufacturer recommendations.
