 PROMASTOP® Cement Fire Stopping Mortar

PROMASTOP® Cement

PROMASTOP® Cement is a lightweight, fire-resistant dry powder cement designed for on-site preparation by mixing with water.

This fine-grade, white cement sets quickly and provides a hard, non-shrinking surface suitable for penetration seals in fire-rated concrete or masonry floors and walls.

Main Applications

PROMASTOP® Cement is used to reinstate fire-rated barriers around service penetrations in concrete and masonry substrates.

It is ideal for both wall and floor openings involving electrical cables, cable trays, conduit, or non-combustible pipes—particularly where a clean, hard, and durable seal is required.

Fire tested performance: Up to -/240/240 fire resistance in qualified wall and floor systems

Non-shrinking and durable: Remains solid and intact under temperature fluctuations

Quick setting and ready to drill: Fast curing and supports post-installation adjustments

Load-bearing potential: When installed at recommended thickness, may support limited loads in floor applications

Flexible application: Can be mixed to pourable or packable consistency based on use case

Clean installation: White colour ensures visibility and clean finish
