Bonding Agent
Sikacoat
A bonding agent that improves adhesion between existing concrete/mortar and a new layer.

Product Description
Sikacoat is a bonding agent that acts as an adhesive layer between old concrete/mortar and a new layer of material on top. This product helps prevent delamination (the new layer separating from the old substrate) that often happens in concrete repair or joining work.
Uses
- Joining existing concrete with a new pour
- Surface preparation before plaster/repair mortar application
- Concrete structure repair work
- Base layer before certain finishing applications
Advantages
- Improves adhesion — reduces the risk of delamination between layers.
- Easy to apply — can be brushed directly onto the surface.
- Compatible with cementitious mortar — suited to a range of concrete repair work.
