Angkop Corp / Installation Guide
A clear start.
A sound finish.
A practical field guide for planning, preparing, and installing Flexible Natural Stone™. Start with the actual site conditions, then follow the current panel, adhesive, substrate, and local-code requirements for your assembly.
01 / Before installation
Confirm the assembly before you bond.
Location
Know where it will go.
A dry interior wall is different from a ceiling, wet area, fireplace surround, or exterior facade. Each condition may require different moisture, fastening, clearance, or code considerations.
Substrate
Make the base sound.
The substrate must be stable, clean, dry, and suitable for the selected adhesive. Do not bond over loose paint, dust, dampness, or a surface that moves.
Materials
Use the complete system.
Confirm the panel, substrate, adhesive, tools, and current manufacturer instructions before starting. Dry-plan cuts, openings, seams, and edge details.
Scope
Call a qualified installer when needed.
Overhead, wet, exterior, heat-adjacent, or structurally uncertain installations should be assessed by a qualified installer or design professional before work begins.
Important: This guide is an overview, not a substitute for the product, adhesive, substrate, and local-code instructions that apply to your project. If you are unsure what is behind a wall or ceiling, pause before covering it.
02 / The sequence
Prepare. Plan. Cut. Bond.
01 / Prepare
Make the base ready.
Repair or replace loose or damaged areas. Confirm the substrate is clean, dry, properly supported, and suitable for the intended finish. Fasten new board as specified for the assembly.
02 / Plan
Lay out before bonding.
Dry-fit panels, mark cuts and openings, and decide where seams and terminations will land. Plan movement and perimeter gaps according to the assembly requirements.
03 / Cut safely
Support the panel.
Use a suitable stone-rated diamond cutting method where needed. Support the panel and use eye protection, appropriate respiratory protection, and dust control. Cutting can release fine mineral dust.
04 / Bond and finish
Follow the adhesive instructions.
Use an adhesive verified for the flexible stone panel, substrate, and location. Follow its current instructions for preparation, coverage, placement, working time, and cure before loading or using the installation.
03 / Adhesive guidance
Match the adhesive to the surface.
Primary adhesive system
MegaLite
Angkop’s primary adhesive recommendation for suitable Flexible Natural Stone™ installations. Confirm compatibility with the specific panel, substrate, and location, and follow the latest product data and cure instructions.
Specified details and transitions
Sikaflex adhesives
Sikaflex-11 FC Purform / Construction Sealant-Adhesive: for specified wood, painted-steel, and aluminium applications, and designated edge or transition details, where current manufacturer guidance supports the use.
Sikaflex AT Metal: for compatible metal-to-metal transitions, subject to current manufacturer instructions.
Important: These recommendations are not interchangeable or universal. Confirm suitability for the actual substrate, surface preparation, exposure, and assembly before bonding. Follow the latest manufacturer instructions, and ask a qualified installer when the application is uncertain.
04 / Installer checks
Details that need a decision.
Confirm these items for the actual site. One installation method does not cover every surface or exposure.
- Substrate and support: Verify framing, deflection, board fastening, and movement. Do not rely on bonding to an unstable existing finish.
- Adhesive compatibility: Follow the adhesive manufacturer’s current technical data. Metal, wood-composite, coated, and transition details may need different preparation or a trial for adhesion.
- Wet and exterior assemblies: Specify moisture management, waterproofing or weather control, compatible substrate, thermal movement, and exposure-rated materials as applicable.
- Ceilings and heat: Confirm overhead support and adhesive suitability. At fireplaces, follow appliance clearances and local requirements.
- Movement and edges: Plan perimeter, transition, and control joints so panels are not locked tightly between rigid surfaces.
- Code and approvals: Do not use a product test result as approval of a complete wall assembly. Check local code and the authority having jurisdiction where required.
Do not skip the site check.
Do not install over a wet, loose, dusty, or flexing base. Do not assume existing tile, painted metal, or textured ceilings can be covered without preparation. Stop and get qualified advice when the assembly is uncertain.
