🛠️ How to Apply Sikadur 43 HS

1️⃣ Surface Preparation

• Ensure the surface is clean, dry, and free of oil, grease, loose materials, and old coatings.
• Use sandblasting, grinding, or high-pressure water-jetting for proper surface preparation.
• Remove all standing water before application.

2️⃣ Priming

• For dry substrates, use Sikadur®-43 HS Primer.
• For damp surfaces, use Sikadur®-31 CF as a bonding primer.
• Always apply wet-on-wet to ensure proper adhesion.

3️⃣ Mixing

• Mix Part A (resin) and Part B (hardener) for at least 2 minutes using a low-speed electric drill (max 500 rpm).
• Once uniform, add Part C (aggregates) and mix until you achieve a homogeneous mortar.

4️⃣ Application

• Apply the mixed mortar while the primer is still tacky.
• Compact and trowel firmly into place to ensure proper bonding.
• For large areas, ensure the layer thickness does not exceed 15 mm.

5️⃣ Cleaning

• Immediately clean tools with Sika® Colma Cleaner after use.
• Hardened or cured material can only be mechanically removed.

⚠️ Important Considerations

🚧 For external applications, seal the surface with Sikafloor®-94 MY.
🚧 Maximum thickness per layer: 5 cm (15 mm for large areas).
🚧 Minimum age of concrete before application: 3–6 weeks (depending on climate).
🚧 Always consult local regulations for specific applications.
