Product Overview

Rockwool Ablative Coating Liquid supplied in 5L tubs. Water-based, ready-to-use ablative coating designed to enhance the fire-resistant properties of Rockwool stone wool products. 

When applied to the surface of Rockwool FireStop or Ablative Coated Batts, the coating forms a protective char that resists flame spread and insulates the underlying mineral wool core under fire exposure.


The coating dries to a flexible white surface finish, creating a stable and durable barrier that improves fire integrity while maintaining ease of application. It can be brush or spray applied directly on-site and provides an excellent substrate for compatible adhesives and fixing sealants.


Available in white as standard, the coating ensures effective fire protection and a uniform finish across large surface areas.

Features & Benefits

  • Enhanced fire resistance: Improves the fire performance of Rockwool stone wool slabs by forming a protective, insulating char.
  • Easy application: Ready-to-use viscous coating suitable for both brush and spray application on site.
  • Durable finish: Dries to a sound, flexible white surface that resists cracking and remains stable under heat exposure.
  • Versatile compatibility: Suitable for use with Rockwool FireStop Slabs and Ablative Coated Batts.
  • Repair and maintenance use: Allows site-applied repair of minor surface damage to pre-coated fire-stopping slabs.
  • Container size: Supplied in 5L tubs for controlled, practical application in construction and refurbishment projects.


Applications

  • Fire-stopping systems: Applied to Rockwool stone wool slabs to upgrade or restore fire resistance at wall and floor junctions.
  • Site repairs: Used to repair damaged or cut surfaces on Rockwool Ablative Coated Batts after installation.
  • Penetration sealing: Supports reinstatement of fire resistance and acoustic performance around pipes, cables, and service openings.
  • Surface finishing: Provides a smooth, flexible coating suitable for painting or adhesive bonding after curing.


Installation Guidance

  • Preparation: Ensure surfaces are clean, dry, and free from dust or debris before coating.
  • Application method: Apply evenly by brush or spray to achieve full coverage of the slab surface.
  • Drying time: Allow coating to dry thoroughly before handling or overcoating; drying time depends on ambient conditions.
  • Repairs: Apply an additional layer over damaged areas or cut edges to reinstate the protective barrier.
  • Storage: Keep the container sealed when not in use and store in a frost-free environment away from direct sunlight.


Compliance & Performance

  • Material specification: Water-based ablative coating formulated for use with Rockwool stone wool fire-stopping products.
  • Finish: Dries to a flexible, white surface.
  • Compatibility: Suitable for use on Rockwool FireStop Slabs and Ablative Coated Batts.
  • Fire performance: Enhances the fire-resistant and smoke-sealing characteristics of treated Rockwool stone wool.
  • Environmental compliance: Water-based formulation containing no halogens or volatile organic compounds (VOCs).
  • Important note: Fire performance is dependent on the complete system build-up and installation in accordance with Rockwool’s tested specifications.
