PYE RENDER-COAT 921(PYE 921 CEMENT RENDER/ SKIM COAT BASE)

PYE Render-Coat 921 (PYE 921 Cement Render / Skim Coat Base)

Introduction

PYE Render-Coat 921 is a high-performance, polymer-modified cementitious plaster specially formulated for base rendering, smoothing, and surface leveling on concrete and masonry walls. It replaces traditional site-mixed sand-cement renders with a factory-blended mixture, offering superior bonding strength, resistance to shrinkage cracks, and excellent workability for both interior and exterior wall applications.

Key Features & Advantages

• High Bonding Strength: Polymer-modified formulation provides strong adhesion directly to smooth concrete surfaces, clay bricks, and AAC block walls without peeling.

• Shrinkage-Compensated & Crack Resistant: Formulated with fine-graded fillers and additives to prevent hairline cracking and shrinkage voids during curing.

• Premixed Consistency: Factory-controlled quality ensures a uniform, reliable mortar mix, eliminating site-mixing ratio errors.

• Weather & Water Resistant: Suitable for both internal partitions and external facades exposed to weather elements.

Primary Applications

• Base Wall Plastering (Render Coat): Initial plaster layer over raw concrete, red clay bricks, sand bricks, and lightweight blockwork.

• Surface Leveling & Patching: Filling surface hollows, honeycombs, and minor alignment defects on walls and soffits.

• Substrate Preparation: Creating a smooth, flat base for fine skim coating (e.g., skim coat halus) or tile installation.
