Innovative Seismic Stabilization System for Non-Structural Walls

Introduction
Wall Mesh Mortar (WPC) offers an advanced solution for the seismic strengthening of non-structural walls in buildings. This system involves the application of fiberglass mesh strips to the wall surface, followed by a layer of mineral plaster. The resulting cementitious composite enhances wall resistance against out-of-plane seismic forces.

WPC is classified under Fabric Reinforced Cementitious Matrix (FRCM) systems, with design principles aligned with ACI 549 standards. It provides an effective alternative to traditional wall post techniques used in seismic bracing.

Preparation Instructions

• For cement-based plaster: Mix with clean water at a ratio of 8:1 (plaster to water).

• For gypsum-based plaster: Mix at a 2:1 ratio.

• Use a mechanical mixer to ensure a uniform, lump-free consistency.

Application Steps

1. Apply the first layer of plaster to the masonry substrate (concrete block, lightweight aggregate, clay, or AAC).

2. Immediately press the fiberglass mesh onto the fresh plaster.

3. Apply the second layer of plaster over the mesh for encapsulation.

4. Use intermittent steel angle connectors with structural epoxy and fasteners (nails or anchors) to fix the mesh at designated intervals to adjacent structural members.

Advanced Fiber Mesh Reinforced Cementitious Facade System

Introduction
Textile Reinforced Concrete (TRC) is an innovative cement-based facade system reinforced with a high-strength fiber mesh. The facade structure includes:

• A 15–20 mm thick cementitious mortar layer

• A 3–4 mm specialized polymer mortar layer reinforced with fiberglass mesh embedded within it

• A durable final colored coating available in multiple colors and textures

Main Components

• Cementitious mortar base layer

• Specialized polymer mortar layer reinforced with fiberglass mesh

• Protective and decorative colored top coating

Key Benefits of TRC Facade

• Lightweight construction reduces load on structures

• High tensile strength enhances resistance to cracking and deformation

• Thin profile enables sleek, modern designs

• Excellent flexibility in architectural design

• Outstanding durability ensures long-lasting performance

Versatile, Durable, and Decorative Finish for Interior & Exterior Walls

Overview
PTC Colored Polymer is a decorative and protective coating designed for both interior and exterior surfaces. It is ideal for application on cement, concrete, brick, and plaster walls. Thanks to its modified polymer-cement composition, this product enables the creation of aesthetically diverse and textured finishes. It not only adds beauty and texture but also improves durability and provides a cost-effective, long-lasting facade solution.

Key Features

• Suitable for both interior and exterior walls

• Can be applied to cement, concrete, brick, and plaster

• Available in a wide range of colors

• Resistant to cracking and environmental factors

• Lightweight and economical

• Long-lasting aesthetic finish

Surface Preparation
Ensure the substrate is solid, clean, and smooth. Remove any dust, oil, or loose materials. Lightly moisten the surface if necessary.

Mixing Instructions

• Mix 26% clean water by weight with the powdered polymer mortar.

• Use a mechanical mixer to ensure a uniform blend.

• Stir until a smooth, paste-like consistency is achieved.

Application
Apply the prepared mixture evenly using a trowel or suitable finishing tool to achieve the desired texture or decorative pattern. Avoid delays, as the mixture should be used within 40 minutes at 20°C. Drying time may vary with ambient conditions.

Technical Data

• Color: Wide range of color options available

• Compressive Strength: > 0.1 MPa

• Adhesion Strength: ≥ 0.7 MPa

• Workability Time: ~40 minutes at 20°C

• Initial Drying Time: ~24 hours

• Final Curing Time: ~7 days

• Density: ~1.6 g/cm³

• Chemical Base: Modified polymer-cement

The external final coating is applied by spraying with a pump or by hand (with a trowel) on the under-work surface that is clean and free of sticky, oily and scum materials. Excess mortar is removed from the surface and returned to the container. If needed, it is possible to apply an additional layer on top of the first layer by considering a drying period of one day.  If there are holes or a hairline crack on the surface, fill them with the external final coating and next day apply the external final coating. Moisturize the external final coated mortar with a little spray of water on the next day of applying.
