📦 Packaging & Product Information

• Product Name: YTL Quick Mix Thin Plaster 386+

• Pack Size: 25KG per bag

• Colour: Grey

• Shelf Life: 6 months (sealed, dry storage)

• Water Requirement: Approx. 0.21–0.23 water-to-powder ratio

• Recommended Mixing Water: ~8.5–9.0 litres per 25KG bag

Store in a dry, covered area, off the ground and protected from moisture.

📐 Coverage Calculation (Corrected & Verified)

At 10mm thickness, estimated coverage is:

• Approx. 2.0 – 2.4 m² per 25KG bag

Coverage Logic:

1 m² at 10mm thickness requires approximately 20–22 kg of mortar (depending on substrate condition and wastage).
Therefore, a 25KG bag realistically covers about 2.0–2.4 m².

⚠ Coverage may vary depending on:

• Surface evenness

• Substrate absorption

• Application method

• Site wastage

For accurate project planning, always allow 5–10% extra material.

2️⃣ Mixing Procedure

• Add 8.5–9.0 litres clean water into a mixing container

• Slowly add one 25KG bag of powder

• Mix using electric mixer for 3–5 minutes until smooth

• Let rest briefly, then remix before application

⚠ If material sits unused for more than 30 minutes, remix before use. Do not add excessive water.

3️⃣ Application

• Apply using steel trowel

• Recommended thickness: Up to 10mm per layer

• Maximum build-up: 15mm (multi-layer application recommended)

• Allow each layer to set before applying the next

4️⃣ Curing

• Keep surface damp during curing

• Protect from rapid drying, strong wind, or direct sunlight

• Proper curing reduces shrinkage cracks
