MCM Installation Overview

Explore the key steps of MCM flexible stone panels installation, from substrate preparation and adhesive selection to panel installation, joint finishing and final inspection.

01 Substrate Preparation

Before installing MCM Flexible Stone Panels, inspect the substrate carefully to ensure it is sound, stable, clean, sufficiently flat and suitable for the installation system.

Remove dust, grease, loose material, unstable coatings and other contaminants. Repair cracks, damaged areas and significant unevenness before installation.

Pre-Installation Checks

  • Substrate Flatness — Level uneven areas before installation.
  • Surface Condition — Remove loose, peeling or hollow coatings and weak material.
  • Efflorescence — If efflorescence is present, apply one coat of alkali-resistant primer after appropriate surface treatment.
  • Moisture Condition — Ensure the substrate is suitable for the selected installation system.
  • Cleanliness — Remove dust, grease and other contaminants that may affect bonding.

Substrate-Specific Treatment

Concrete & Masonry

For concrete or masonry walls requiring leveling, apply 2–3 coats of crack-resistant mortar with mesh reinforcement, followed by an alkali-resistant primer or bonding agent where specified.

Gypsum Board, Aluminum, Glass & Ceramic Tile

For these specialty substrates, apply one coat of quartz primer at 0.4–0.5 kg/m² to improve bonding.

Wood-Based Substrates

Apply one coat of oil-based wood sealer at 0.2–0.3 kg/m² to help prevent moisture-related warping.

Painted Surfaces

Completely remove peeling, flaking or hollow paint coatings before installation. The remaining surface must be sound and suitable for the selected installation system.

Installation Conditions
  • Do not install at temperatures below 5°C (41°F).
  • In cold-weather construction, complete daily installation by 3:00 p.m. to allow sufficient curing time.
  • Avoid impact or disturbance for the first 24 hours.
  • Full strength is achieved after approximately 72 hours, according to the installation system.
  • Avoid outdoor installation during wet weather to prevent water from affecting bonding performance.

Important

Substrate condition directly affects installation performance. Do not install over unstable, contaminated or unsuitable surfaces. Primer, leveling materials and treatment methods should be compatible with the substrate and the selected installation system.

02 Adhesive Selection

Choose compatible materials for the complete installation system.

01 Adhesive

Select the adhesive according to the panel backing, substrate and installation environment.

For suitable mineral substrates, polymer-modified cementitious adhesives such as C2, C2TE, C2TE S1 or S2 may be considered where appropriate.

Other adhesive systems may be suitable for specific substrates or conditions.

02 Primer / Interface Treatment

A suitable primer or bonding interface treatment may be required for glazed, dense, smooth or low-absorption surfaces.

Select the primer according to the substrate and adhesive system.

03 Jointing Material

Use a compatible jointing material to create clean and visually consistent seams.

The jointing material should coordinate with the adhesive and surrounding panel surface.

Where appropriate, a compatible pigment powder may be used to adjust the jointing material closer to the panel color. Confirm compatibility before use.

Key checks

  • Panel and substrate compatibility
  • Interior or exterior conditions
  • Moisture and temperature exposure
  • Primer requirements
  • Jointing material compatibility
  • Joint color and overall appearance

For detailed adhesive selection guidance, see:

How to Choose the Right Adhesive for Flexible Stone Veneer →

Important

The substrate condition directly affects adhesive performance. Do not install over unstable, contaminated or unsuitable surfaces.

03 Layout & Cutting

Before cutting any panels, determine how the panels will be arranged on the substrate. Establish the starting point, panel direction, corners, openings, edges and joint locations first. Then plan the cuts according to the installation layout.

01 Plan the Layout

Review the installation area and decide:

  • Starting point and installation direction
  •  Panel arrangement and pattern direction
  •  Position of corners and openings
  • Panel edges and visible seams
  •  Areas requiring full panels or cut panels

02 Mark the Substrate

Mark clear horizontal and vertical reference lines on the substrate according to the planned layout.

Use a laser level, chalk line or other suitable measuring tools to establish accurate reference lines before applying adhesive.

03 Dry-Fit the Panels

Place the panels against the substrate without adhesive to confirm the planned arrangement.
Check the pattern direction, corners, openings, edges and joint positions. Adjust the layout before making any cuts.

04 Cut the Panels

Cut the panels according to the marked dimensions using the appropriate approved cutting tool.
For complex shapes or openings, make the cut gradually and check the fit before removing additional material.

Key checks

  • Measure the installation area accurately
  • Establish reference lines
  • Dry-fit panels before applying adhesive
  • Mark openings, corners and required cuts
  • Check panel orientation and seam locations
  • Cut panels using the appropriate approved tool

Always test the selected cutting method on an off-cut before making production cuts. Cutting methods can vary according to panel construction and thickness. DEVOX

Important

Test the selected cutting method on an off-cut before making production cuts. Cutting methods may vary according to panel construction and thickness.

04 MCM Flexible Stone Panels Installation

How to install flexible stone panels: MCM Flexible Stone Panels can be installed on properly prepared substrates, including concrete and cement render, cement board, fiber-cement board, gypsum board, plasterboard, plywood, fire-resistant plywood, wood-based boards, ceramic and porcelain tile, metal, aluminum, and glass.

The substrate must be sound, stable, clean, and sufficiently flat, with suitable surface preparation and primer or interface treatment where required. Select the adhesive according to the substrate, panel backing, and installation conditions.

MC Stone

The standard installation process is:

01 Set Out

Establish reference lines according to the planned layout.

02 Apply Adhesive

Apply the selected alkali-resistant adhesive evenly to the substrate using the approved method.

03 Install the Panels

Position the panels according to the reference lines and press them firmly into place.

04 Finish the Joints

Fill the joints with the compatible jointing material. Where permitted by the product system, panels may also be installed with close joints.

05 Clean the Surface

Remove adhesive and installation residue from the panel surface after installation.

MC Brick

The standard installation process is:

01 Set Out & Position

Establish reference lines and determine the brick layout before installation.

02 Apply Adhesive to the Back

Apply the selected alkali-resistant adhesive evenly to the back of the product.

03 Install & Adjust the Joint Width

Position the product and gently move or press it up and down to adjust the alignment and required joint width.

04 Fill the Joints

Place the compatible jointing material into a grout bag and fill the joints evenly.

Where specified by the installation system, silicone sealant may also be used for joint filling.

05 Form the Joints

For a 6 mm joint, use an 8 mm steel rod as a jointing guide. Pull the rod through the joint while the jointing material is partially dry to form a consistent joint.

06 Remove Excess Material

Use a putty knife to remove excess jointing material from the product surface and edges.

07 Clean the Surface

Use a sponge to gently clean the surface and remove any remaining jointing material or residue.

Important
  • Use an alkali-resistant adhesive suitable for the MC product and substrate.
  • Use the compatible jointing material specified for the installation system.
  • If adhesive contaminates the product surface during installation, do not wipe it while wet.
  • Allow the adhesive to dry, then carefully remove the residue with a putty knife or dry sponge.

05 Corner & Edge Treatment

During flexible stone installation, MCM Flexible Stone Panels are typically installed with tight joints for a clean, continuous appearance. Where a defined edge, corner protection, or decorative transition is required, metal trim profiles can be used as an alternative edge treatment.

Metal trims should be installed before the adjacent panel is cut and positioned, so the finished panel edge can be accurately aligned with the trim.

Metal Trim Installation

Required Tools & Materials
  • Metal trim profile
  • Angle grinder
  • Utility knife
  • Marker
  • Handheld cutting machine or workbench
  • Structural adhesive
  • Straightedge
  • Tape measure
  • Rubber tapping board

Installation Steps

01 — Cut the Metal Trim

Mark the required length on the metal trim and cut it using a handheld cutting machine or workbench cutting setup.

02 — Apply Structural Adhesive

Apply structural adhesive evenly to the bonding surface of the metal trim.

03 — Install the Metal Trim

Position the trim along the designated corner or exposed edge and press it firmly into place.

04 — Measure the Actual Panel Dimension

After the trim has been installed, measure the actual wall dimension between the installed trim and the adjacent reference point.

05 — Cut the Panel

Transfer the measured dimension to the MCM Flexible Stone Panel and cut the panel accordingly using the appropriate cutting tool.

06 — Refine the Panel Edge

Use an angle grinder to carefully grind the cut edge of the panel, creating a flatter and cleaner edge for a closer fit against the metal trim.

07 — Install the Panel Along the Trim

Apply the selected adhesive and position the panel tightly along the edge of the metal trim.

08 — Press the Panel

Use a rubber tapping board to press the panel evenly and firmly into position.

Do not press the panel directly with your hands.

Key checks

  • Tight joints are suitable for many MCM Flexible Stone Panel applications where a continuous surface appearance is required.
  • Metal trims can be used where a defined edge, corner detail or decorative transition is required.
  • Install and secure the metal trim before taking the final panel measurement.
  • Measure the actual installed dimension rather than relying only on the original drawing dimension.
  • The panel edge should be refined where necessary to achieve a clean fit against the trim.
  • Use a structural adhesive compatible with both the trim and the installation system.
  • Follow the product-specific requirements for corner and edge details.

06 Joint Finishing

Create clean and consistent panel joints.

Follow these six steps to achieve clean and visually consistent joints.

01 Apply Masking Tape

After the panels are bonded, apply masking tape along both sides of the joint to protect the panel surface during grouting.

Note: Do not apply masking tape to textured or uneven-surface panels.

02 Prepare the Jointing Material

Mix a compatible pigment powder into the jointing material to achieve a color that matches the panel surface. Place the prepared material into a grout bag.

03 Fill the Joint

Apply the color-matched jointing material evenly into the joint using the grout bag.

04 Tool the Joint

Use a jointing tool to smooth and shape the joint for a clean finish.

05 Remove the Masking Tape

Allow the jointing material to dry completely, then carefully remove the masking tape.

06 Clean the Surface

Use a dry sponge to gently remove remaining material and clean the panel surface.

Installation complete.

07 Final Inspection

Once installation and finishing are complete, inspect the entire surface under suitable lighting.
Check panel alignment, surface contact, corners, edges and joints. Remove remaining adhesive or jointing residue according to the relevant product instructions.

Key checks

  • Panels are correctly aligned
  • Surface is securely bonded
  • No visible lifting or loose edges
  • Corners and edges are properly finished
  • Joints are clean and consistent
  • Surface is free from installation residue
  • Completed areas are protected during curing

Follow the adhesive manufacturer’s required curing and protection conditions before placing the installation into service. A final inspection should assess the complete installation—not just the appearance of the panels. HeyMaterials
