The EPOXY CRACK FILLER is a 100% solids two-component

(1A:1B) gel epoxy crack repair which is virtually VOC-free. The

product is easy to use and can be applied on horizontal and

vertical surfaces. It also offers a long pot life and working time

but cures very quickly allowing the installation of the base coat

or primer minutes after the application of the EPOXY CRACK

FILLER. This product possesses superior mechanical and c

hemical properties suited for residential, commercial and

industrial applications. The formulation is based on a high-per-

formance cycloaliphatic polyamine technology displaying

outstanding properties.

Epoxy Crack Filler (Labsurface)

The Epoxy Crack Filler is a high-performance, VOC-free, 100% solids two-component gel epoxy designed for filling cracks and voids in concrete surfaces. It is suitable for both horizontal and vertical surfaces in residential, commercial, and industrial environments.

This material consists of two components: Part A (white) and Part B (black), which are mixed in a 1:1 ratio by volume to yield a light grey gel. It is compatible with LABPOX® epoxy systems, LABFAST® and LABSHIELD® polyaspartic coatings, and can be used in conjunction with LABPOX® MVB as a moisture mitigation system when necessary.

• Full Cure Time: 24 hours
• Recoat Window: 60 minutes (max 24 hours without sanding)
• Shelf Life: 1 year in unopened containers
• Surface Prep: Concrete must be clean, dry, free of contaminants, and moisture content must be below 4% (measured using Tramex® CME/CMExpert).

• UV Stability: Not specified (typically not UV-stable unless stated)
• Coverage: Not explicitly stated, designed for gap-filling (coverage depends on void size)
