205 Flexible Joint Filler is a coloured, two pack, pourable, flexibilised epoxy filler/sealant. The consistency of the mixed sealant allows direct pouring of the sealant into horizontal joints.
Hard and tough enough to protect joint edges from heavy wheel loading, 205 Flexible Joint Filler possesses sufficient flexibility to accommodate a degree of movement (10% of the joint width), and is particularly suitable for filling saw cut joints in long strip floor construction.

Joint Design
When using 205 Flexible Joint Filler, the joints shall be designed to ensure that concrete movement due to shrinkage and temperature fluctuations does not exceed 10% of the joint width.
- For joints up to 12mm wide, the depth of sealant should be equal to the width.
- For joints over 12mm wide the depth of sealant should not exceed 20mm.
- Joints over 25mm wide are permissible
Surface Preparation
New concrete floors shall be a minimum of 21 days old. Joint surfaces shall be sound, clean and free from laitance, dust and other contaminants.
Joint edges are best prepared by grinding or power wire- brushing; ensuring that all spoil and residual dust is removed by blowing with dry, oil free, compressed air.
De-bonding tape should be used in the base of the joints otherwise a polyethylene foam backing strip should be inserted to the appropriate depth.
Mixing
Pour the contents of the CURING AGENT container into the BASE container and thoroughly mix, preferably by mechanical means until a uniform consistency is achieved.
Mixing Ratio
- By Weight = 100 Base : 42.1 Curing Agent
Application
The mixed material may be poured directly into the prepared joints to level.
Alternatively, 205 FLEXIBLE JOINT FILLER may be poured into empty cartridge tubes and gunned into the joints using a sealant gun. It may be necessary to top up to level after a few minutes when the sealant has settled into irregularities.
Equipment Cleaning
Clean equipment with 109 TOOL CLEANER prior to curing of the sealant.
Curing
Will have cured sufficiently following 24 hours cure @ 20°C to allow trafficking.
Full chemical resistance will be achieved following 7 days cure @ 20°C.
At lower temperatures cure times will be increased.
Limitations
- Do not apply to wet or uncured concrete surfaces.
- Do not apply at temperatures of 3°C or less.
