Polymer crack-resistant rendering mortar

Implementation Standard: JG 149-2013

Features: Crack resistance, high bonding strength, thin-layer construction, durability

Usage:

1. Substrate treatment:

The base surface must be firm, free of oil stains and loose materials. Construction can only proceed after the acceptance of the insulation board bonding.

2. Ratio and mixing:

Water-cement ratio: 1:4 (weight ratio), mix with an electric mixer until a uniform paste is formed, and let it stand for 5 minutes to mature. The mixed slurry must be used within 2 hours to avoid hardening and failure.

3. Rendering and reinforcement:

Construction in two passes: First pass 2mm thick → press in mesh (overlap ≥50mm) → second pass to cover to a total thickness of 3-5mm.

4. Environmental control:

Temperature: Construction at 5-35℃, avoid excessive water addition at high temperatures, and handle low temperatures according to winter construction specifications.

Prohibition: No work is allowed on rainy days or in winds of level 5 or above.
