Control Joint Systems - Sika® Loadflex-524 EZ
Two Component, Semi Rigid, Polyurea Control Joint Filler
Sika® Loadflex-524 EZ is a technologically advanced, two-component, quick-setting, semi-rigid, solvent-free, self-levelling control joint filler.
- Quick-set formula reduces down time.
- Material can be shaved off smooth as early as 5 minutes or as late as 24 hours after placement at 73 °F (23 °C).
- Cures at temperatures down to -13 °F (-25 °C).
- Hard, load-bearing filler designed to withstand industrial traffic.
- Provides even load transfer across floor joints, thereby protecting joint edges from breaking down under traffic.
- Two components, easy to use, 1:1 mix ratio.
- Improved consistency to allow easier dispensing and reduced blockage of equipment.
- Seals joints from collecting dirt, dust and debris.
- Excellent moisture sensitivity.
- For use in Food Plants where floor surfaces must be kept clean.
Usage
- Sika® Loadflex-524 EZ is recommended for use as filler for static interior, horizontal saw cuts or preformed control and construction joints.
- Typically installed in facilities such as warehouses and industrial plants, where such joints are subject to load-bearing conditions involving wear and impact.
- Sika® Loadflex-524 EZ is also used for repairing interior concrete slabs that have experienced random cracking due to shrinkage.

Application Steps
SUBSTRATE PREPARATIONSurface must be clean, sound and dry. Remove all surface contaminants including without limitation contaminants such as dust, grease, curing compounds, impregnations, waxes, foreign particles and disintegrated materials that might prevent bond. Preferred methods of joint cleaning include using a dustless saw with diamond blade, with blade slightly wider than the joint so both sides of joint are cleaned or sand blasting. If unusual conditions are present contact Sika Technical Services.
MIXINGPre-mix each component thoroughly before using. Sika® Loadflex-524 EZ must be machine mixed / dispensed using a 1 to 1 ratio, plural component pump and 30 element static mixing nozzle. Note: Sika® Loadflex-524 EZ sets too quickly to allow hand mixing.
