Stopgap 600 Base Levelling Compound 25Kg

Stopgap 600 – Deep Section Base Compound

Stopgap 600 is a high-performance, fibre-reinforced deep section base compound engineered for fast, economical floor levelling in both light-duty and heavy-duty internal environments. It’s ideal for raising subfloor levels quickly—on sound absorbent or non-absorbent surfaces—so you can install floorcoverings without delay.

Key Features & Benefits:

• Fast set time: Walk-on hardened within around 3 hours, enabling swift project progression

• Wide application thickness: Smooths depth from 5 mm up to 75 mm in a single application for efficient lift-ups

• Versatile substrate compatibility: Works over concrete, sand/cement screeds, tiles, epoxy and polyurethane resins, and waterproof membranes

• Protein-free & low odour: Safe for use in biologically sensitive areas, such as hospitals

• Hand or pump application: Allows rapid coverage—ideal for large areas or tight schedules

Performance & Usage:

Applied at 5 mm, Stopgap 600 yields approximately 2.8 m² per 25 kg bag. As application depth increases, coverage decreases—e.g. at 15 mm, 20 mm, 50 mm depths accordingly less per bag. The compound remains dimensionally stable and enables floorcoverings after as little as 6 hours, depending on project conditions.
