GQ300 High-Strength Crack-Resistant Self-Leveling Mortar
A high-strength precision leveling base engineered to prepare substrates for PVC flooring, timber flooring, carpet, tile, stone, and other finish systems.
- Thickness
- 3–8 mm
Overview
GQ300 is a high-strength, crack-resistant self-leveling mortar designed to correct flatness and improve base strength ahead of a finish flooring system. Its flowing consistency allows it to self-level across the substrate, reducing the labor and variability associated with manual screeding, while its engineered formulation is designed to reduce shrinkage and cracking risk under specified application conditions.
Key Features
High Early Strength
Rapid strength development supports faster project sequencing ahead of finish installation.
Precision Leveling
Self-leveling flow evens out substrate irregularities for a consistent finish-ready base.
Reduced Cracking Risk
Formulated to reduce shrinkage and cracking risk under specified application conditions.
Multi-Finish Compatible
Suitable as a base for PVC, timber, carpet, tile, and stone finish systems.
Application Scope
- Schools and educational facilities
- Hospitals and healthcare buildings
- Commercial showrooms
- Offices and hotels
- Projects requiring improved flatness and base strength

Process & Application Guidance
- Step 1
Substrate Assessment
Base structural slab is inspected for flatness deviation and load-bearing readiness.
- Step 2
Substrate Preparation
Surface is cleaned and treated with a bonding interface layer.
- Step 3
Metered Mixing
Mortar is mixed to specification using programmed pumping and mixing equipment.
- Step 4
Self-Leveling Placement
Material is placed and allowed to self-level across the working bay.
- Step 5
Curing
Controlled curing prepares the base for finish flooring installation.
- Step 6
Finish Handover
Prepared base is verified for flatness and strength before finish trades proceed.
