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.

01

Existing ceiling or wall — popcorn, drywall, concrete, masonry. Leave as-is if structurally stable. In many retrofit applications, no scraping or demolition is required.

02

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.

03

MegaLite adhesive — applied to the panel back with a notched trowel. Permanent high-strength bond for vertical and overhead applications.

04

Flexible Natural Stone™ — pressed to surface. Layout (stacked, staggered, bookmatched, random) is a design choice.

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.

—Stagger all substrate board seams — offset joints by at least half a board length
—Screw into joists at proper spacing — not just into the existing surface layer
—Eliminate flex movement before bonding — a rigid, stable substrate is the foundation of a clean finish

Substrate Guide

03

Choosing the Right Board

MegaLite bonds to all standard construction substrates when properly prepared.

Walls — All Environments

—Drywall — standard for residential and commercial interiors
—Concrete and masonry — direct bond on properly prepared surfaces
—Cement board — professional system for wet zones
—Existing cladding and tile — over-cladding without demo, where substrate is sound
—Curved surfaces — panels flex to shape around columns and arches

Dry Ceilings — Retrofit & New Build

01Assess existing ceiling — popcorn or existing texture can remain if stable
02Install 1/4" drywall or lightweight board — screwed into joists, seams staggered
03Apply MegaLite and bond Angkop panels

Wet Ceilings — Bathroom, Spa & Hospitality

—Schluter Kerdi-Board — lightweight, waterproof, ceiling-friendly
—Wedi Board — rigid, waterproof, easy to handle overhead
—GoBoard — lightweight tile backer, moisture-resistant

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.

01Track Saw — best for long straight cuts. Diamond blade, slow feed rate, full panel support.
024.5" Angle Grinder — field cuts, curves, detail work. Continuous rim diamond blade.
03Aviation Snips — curves, outlet cutouts, ceiling edge trimming.
04Oscillating Multi-Tool — outlet cuts, ceiling edges, trimming panels in place.

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

05

Adhesive & Application

MegaLite is the recommended adhesive for all Angkop installations — walls, ceilings, wet zones, and over existing surfaces.

01MegaLite Cement Adhesive — bonds to drywall, concrete, masonry, cement board, Kerdi-Board, Wedi, GoBoard.
02Notched Trowel — for even adhesive coverage across the panel back.

Movement & Expansion

06

Accommodating Building Movement

—Leave perimeter gaps at ceilings, walls, and corners
—Allow transition gaps at material changes — stone to tile, stone to drywall, stone to trim
—Fireplace installations require additional expansion allowance for thermal cycling
—Large-format ceiling installations — account for substrate deflection and seasonal building movement

What to Avoid

07

Where Callbacks Happen

—Unprepared substrates — dusty, wet, failing paint, or loose surfaces
—Dull utility knives on 3–5mm panels — use diamond blade methods instead
—Segmented masonry blades — chip edges and crack corners
—Cutting without PPE — respirator and eye protection required
—Hard-locking panels between rigid surfaces — no movement gap means cracking
—Aligned substrate seams — always stagger board joints
—Raw MDF in humid or wet zones — swells and fails over time
—Heavy 1/2" cement board on ceilings — use 1/4" or lightweight backer instead
—Gluing boards over popcorn without screwing into joists
—Any ceiling flex — screw into joists at proper spacing before bonding
