Sika Concrete Crack Repair

Sika Concrete Crack Repair is a two-part cold cure, thixotropic structural adhesive based on epoxy resin. Sika Concrete Crack Repair is tested according to EN 1504-4.

Benefits

• Applied using a standard sealant gun
• Can be used on damp concrete
• Excellent adhesion
• Non-sagging, can be used for overhead applications
• High load capacity
• Does not shrink on hardening
• Styrene free

Areas For Use

As a structural adhesive for:

• Concrete
• Hard natural stone
• Ceramics, fibre cement
• Mortar, bricks, blocks, masonry, render, etc
• Steel, iron and aluminium
• Wood
• Polyester and epoxy
• Fixing and fastening of handrails, railings, balustrades and supports
• Fixing of window and door frames

For concrete repairs:

Interior, vertical and overhead repairs of:

• Corners and edges
• Hole and void filling
• Crack filling and sealing of non-moving joints
• Joint arrises

Limitations

• Can be used with damp (not wet) substrates. Ensure there is no standing water during application and curing.
• Mortar and concrete must be older than 28 days.
• Adequate substrate strength must be confirmed prior to application.
• Ambient and substrate temperature must be between 10°C and 35°C.
• Apply at a maximum air humidity of 85% (at 25°C).
• Avoid condensation during dew point conditions. Substrate temperature during application must be at least 3°C above dew point.
• Sika Concrete Crack Repair is formulated to have low creep under permanent loading. However, due to the creep behavior of all polymeric materials under load, the long term structural design load must account for creep. Generally, the long term structural design load must be lower than 20-25% of the failure load. Please consult a structural engineer for load calculations for your specific application.
