Proper installation techniques are essential to maximizing the structural performance, fire rating, and thermal
insulation of an EPS Cement Sandwich Wall Panel. While these lightweight panels are designed for swift
assembly, adhering to precise engineering steps ensures a seamless, long-lasting wall structure. This
comprehensive guide outlines the standard installation procedure for modern wall construction.

Step 1: Site Preparation and Alignment

Before installing any panels, clear the site floor and ceiling area of dust, debris, and oil stains. Using a laser level
or plumb line, mark the reference line along the floor, walls, and ceiling where the EPS Cement Sandwich Wall
Panel partition will sit. Accurate marking is crucial to ensure perfectly vertical and flush alignment across the
entire wall span.

Step 2: Preparing and Applying Polymer Mortar

Mix a high-grade flexible polymer mortar with water according to the manufacturer’s instructions. This
specialized adhesive ensures strong bonding between the panels, floor, and adjacent structural columns. Apply
the mortar evenly along the floor groove and the side tongue-and-groove joint of the first EPS Cement Sandwich
Wall Panel using a notched trowel.

Step 3: Positioning and Erecting the First Panel

Carefully lift the first EPS Cement Sandwich Wall Panel into position. Insert the bottom end into the floor mark
and press the side firmly against the wall or column. Use a pry bar at the bottom to adjust the panel's verticality
and level while pressing it snugly into place. The polymer mortar should squeeze out slightly from the joints,
indicating full surface contact. Secure the panel temporarily with wooden wedges driven under the bottom base.

Step 4: Installing Subsequent Panels and Interlocking

Continue the process for subsequent panels. Apply polymer mortar along both the horizontal and vertical
tongue-and-groove joints. Interlock each EPS Cement Sandwich Wall Panel using firm lateral pressure. Check
vertical alignment constantly with a spirit level or laser level after placing each panel. To ensure structural
stability, insert anti-corrosive steel rebar pins angled at 45 degrees between adjacent panels and into structural
concrete beams or columns.

Step 5: Fixing and Anti-Crack Joint Treatment

Once all panels in a section are erected and secured with wedges, allow the polymer mortar to cure for
approximately 24 hours. Remove the wooden wedges and fill the bottom gap completely with fine-aggregate
concrete or non-shrink grout.
To prevent joint cracking over time, apply fiber mesh tape over all panel-to-panel joints and cover it with a thin
layer of crack-resistant polymer plaster. This crucial step guarantees a smooth surface that resists stress and
thermal expansion.

Step 6: Electrical Concealment and Surface Finishing

Routing electrical conduits or plumbing pipes within an EPS Cement Sandwich Wall Panel is straightforward.
Use a portable electric wall chaser to cut grooves into the surface, insert the conduits, and seal the channels
with polymer mortar and mesh tape. Once dry, the wall is ready for final surface treatments, such as painting,
tiling, or wallpaper installation, without requiring heavy plastering.

Conclusion

Installing an EPS Cement Sandwich Wall Panel system is clean, fast, and efficient. Following these
professional steps ensures high structural integrity, smooth surfaces, and long-term durability for residential,
commercial, or office partitioning.
