RonaBond Bedding Mortar is used to bond brick slips, copings and other components to concrete and building surfaces. The cured mortar has high physical strength, is waterproof and frost proof and will not break down through frost action.

Ronacrete Standard Primer is used to provide monolithic adhesion between the mortar, the slip and the substrate. Careful surface preparation is essential to ensure adhesion, long term durability and performance.

Coverage

One 25kg pack of RonaBond Bedding Mortar will fix 70 slips (65mm x 225mm) using a 10mm bed. One 2kg pack of Ronacrete Standard Primer is sufficient for 150 slips (concrete surface and slip).

Instructions for Use

1. The surface to receive the slip must be mechanically prepared to ensure it is structurally sound and stable and strong enough to support the weight of the slip and the mortar
2. The surface must be mechanically abraded by scabbling, needle gunning or similar methods to provide a strong, laitence free profile. Any coatings must be removed back to clean, sound concrete. Clean the surface to remove dust and debris
3. The back of the brick slip / component must be cleaned to remove loose material and any contamination
4. Damp the surface and the back of the slip / component with clean water; remove excess water
5. Apply a single coat of Ronacrete Standard Primer to the damp surfaces; the primer must remain wet or tacky and must not dry before the mortar is applied
6. Mix RonaBond Bedding Mortar as described (see Mixing)
7. Trowel the mortar on to the back of the slip / component, or on to the surface, to a bed depth of 6-12mm (typically)
8. Place the slip / component in to the mortar, position and brace. Ensure total contact between the slip / component, mortar and concrete
9. Support the slip as necessary until the mortar has hardened sufficiently
10. Avoid staining the face of slip with the primer or mortar

Mixing

RonaBond Bedding Mortar provides optimum performance when machine mixed in a forced action mixer (eg. Creteangle pan mixer). Do not use a free fall mixer.

Mix the dry components and when evenly dispersed add the minimum amount of the supplied gauging liquid to provide sufficient workability for compaction and surface finish.

Application Temperature

RonaBond Bedding Mortar can be used in most weather conditions and in a wide temperature range, typically from +3°C to 25°C and above.

Note that at high ambient temperatures the working time of the mix will be reduced; it will be increased at lower temperatures. Ideally store materials between 10°C and 20°C before use.

Sealing

RonaFloor Epoxy Floor Mortar is a resin rich material which does not require a sealer for chemical or wear resistance. RonaFloor Epoxy Floor Mortar may be sealed with a single coat of RonaFloor Epoxy Primer to improve cleanability. Over-sealing will affect slip resistance.

Working Temperatures

RonaFloor Epoxy Floor Mortar Standard or Rapid can be used in most weather conditions and in a wide temperature range, typically from 5°C to 25°C. The minimum working temperature is 5°C. Note that application at higher or lower temperatures will affect working time.

The material should ideally be stored, mixed and applied at 15°C to 20°C. At lower application temperatures the material should be stored at or warmed to 15°C to 20°C prior to use. Application characteristics are severely affected below 10°C.

In areas exposed to sunlight, the substrate can be hotter than the air and material temperature, which may adversely affect the workable life of RonaFloor Epoxy Floor Mortar Standard and may prevent application of RonaFloor Epoxy Floor Mortar Rapid.
