How to repair cracked concrete
Unsightly cracks in concrete not only detract from the look of a garage or patio, they can also lead to further problems as moisture seeps into the concrete.
Luckily, there’s an easy way you can repair a cracked concrete slab or wall and prevent further damage down the track.
Sikadur Concrete Fix is a two part epoxy adhesive and filler that can be used as a bonding bridge adhesive paste for concrete and most building materials.
It’s simple and easy to apply and can be used for repairing cracks, holes and voids in concrete floors and walls.
It also works as a structural adhesive for a range of materials including stone, ceramics, fibre cement, masonry, metal and timber.
To repair cracks in a concrete floor, first ensure that the area is free from dust, grease and surface contaminants.
Concrete fix can be applied to both dry and damp surfaces, but standing water in any voids, pits or pores should be removed prior to application.
While wearing safety glasses and chemical resistant gloves, pre-mix both parts separately, then mix equal parts of each together in a suitable container. Mix thoroughly for three minutes with an electric drill and paddle mixer.
Use a trowel to apply concrete fix to the prepared substrate and smooth it into the crack or to form the desired shape.
