Environmental Conditions for Installation

To achieve the best performance and adhesion of EPS sheets, proper environmental control during installation is essential.

Ideal Conditions:

1. Temperature Range: Between +5°C and +40°C for adhesives and coatings.

2. Humidity: Below 75% relative humidity during application and curing.

3. Avoid installation during rainfall, frost, or direct sunlight.

4. For exterior work, cover freshly applied layers with protective sheets or tarpaulin.

5. Maintain good air circulation to speed up curing of polymer-based adhesives.

Avoid:

• Applying adhesives or coatings on damp or wet surfaces.

• Working under extreme heat, as EPS may expand.

• Installing in windy or dusty environments without proper shielding.

---

21. Layer Curing and Setting Recommendations

Curing is critical for ensuring the strength and adhesion of each layer in the insulation system.

Additional Tips:

• Use light mist curing for cementitious layers (not flooding).

• In high-temperature regions, cover surfaces with wet hessian cloth to avoid premature drying.

• Do not apply the next layer before the previous one has completely set and hardened.

---

22. Integration with Waterproofing Systems

EPS Sheets with Fiber Mesh play a dual role in waterproofing systems — thermal barrier and mechanical protection layer.
Their proper integration enhances the durability of the waterproof membrane and reduces maintenance.

For Roof Waterproofing:

1. Clean the cured waterproof layer (PU, acrylic, or bitumen-based).

2. Lay EPS sheets over it using PU adhesive or bitumen-compatible glue.

3. Ensure tight joints to prevent water seepage between sheets.

4. Apply a protective screed layer (50–75 mm) with proper slope for drainage.

5. Cure the screed completely before applying reflective or protective coating.

For Basement Walls:

1. Fix EPS sheets vertically on the outer wall with PU adhesive.

2. Seal all edges with polyurethane foam.

3. Cover sheets with geotextile fabric before backfilling with soil or sand.

4. Ensure proper drainage behind insulation to avoid hydrostatic pressure.

---

23. Integration with Plaster Systems (EIFS / ETICS)

EPS Sheet with Fiber Mesh is commonly used in External Insulation Finishing Systems (EIFS) or ETICS for exterior wall insulation.

Step-by-Step:

1. Apply adhesive mortar on wall surface and press EPS sheets tightly.

2. Use plastic fixing anchors to secure sheets firmly.

3. Apply a base coat of polymer-modified mortar over the sheets.

4. Embed fiber mesh across the surface ensuring full coverage.

5. Apply second mortar layer to fully cover the mesh.

6. Finish with texture coating or exterior paint.

Advantages:

• Increases building energy efficiency.

• Prevents cracks in external walls.

• Protects the wall from temperature fluctuation and moisture ingress.

---

24. Quality Inspection and Testing

After completion of installation, it is important to perform inspections to ensure the system’s integrity and compliance with specifications.

Checklist for Quality Control:

 Adhesion between sheet and substrate is strong and uniform.
 No visible gaps or unfilled joints between sheets.
 Fiber mesh overlaps are consistent (minimum 100 mm).
 Mortar or coating layer is evenly spread with no bubbles or cracks.
 Waterproof membrane (if applied) is continuous and undamaged.
 Roof or wall slope allows proper water flow and drainage.
 All edges, corners, and penetrations are properly sealed.

Testing Methods:

• Adhesion Test: Randomly pull one sheet after curing to check bond strength.
