PSP 313 Cementitious Sealing Putty

Polymer‑Modified, High‑Quality Compound for Filling Joints & Surface Imperfections

Overview
PSP 313 Cementitious Sealing Putty is a high‑performance, polymer‑modified compound formulated for repairing joints, cracks, and blemishes on concrete, brick, gypsum, and cement‑rendered walls. Ideal for construction, industrial, and infrastructure projects, it delivers exceptional strength, adhesion, and long‑term durability.

Key Features

• High compressive strength: ≥ 20 MPa

• Excellent flexural strength: ≥ 5 MPa

• Superior bond to concrete, brick, gypsum, and cement surfaces

• Low shrinkage and crack‑resistant finish

• Easy mixing and trowel‑grade consistency

• Suitable for interior and exterior applications

Surface Preparation
Ensure the substrate is clean, sound, and free of dust, oil, or loose particles. Joints and cracks should be dry. Lightly dampen very dry surfaces before application (no standing water).

Mixing Instructions

• Add 27 % clean water by weight to the dry powder.

• Mix mechanically until a smooth, lump‑free paste forms.

Application
Apply the putty with a trowel or putty knife, pressing firmly to eliminate air pockets. Over‑fill slightly, then scrape back flush and smooth the surface. Remove excess material promptly.

Working Time
≈ 60 minutes at 20 °C (shorter in warm, longer in cool conditions).
