Coverage will vary dependent on the flatness of the background, the profile of the tile back and the adhesive bed thickness. To cover 1m2 , approximately 1.25kg of powder will be required for every mm thickness of solid bed adhesive. This equates to the following approximate coverage per 20kg bag:

Backgrounds must be sufficiently dry and strong enough to carry the total weight being applied. All surfaces must be clean, sound, flat and free from contaminants that could inhibit adhesion, such as dust, dirt, oil, grease, laitance, and curing agents. Moisture sensitive backgrounds in wet locations will need protecting using Kelmore's waterproofing systems.

A 20kg bag of MoreBond Rapid C2 Grey should be mixed with approximately 4.0 litres of clean, cold water. The amount of water used in the initial mixing can be adjusted slightly to obtain the optimum adhesive consistency for the specific application but must always remain slump-free. Pour the water into a clean bucket before gradually adding the powder. Mix thoroughly until a smooth, creamy, slump-free consistency is achieved. To maximise the pot life, open time and workability, allow the mixed adhesive to stand for 2 minutes then re-mix briefly before use.

MoreBond Rapid C2 can be used up to 15mm thick. Apply the mixed adhesive to the wall or floor before using a notched trowel to serrate consistent, straight ribs of adhesive. Bed in the tiles within the open time ensuring good contact with the adhesive. The adhesive coverage behind the tile must be sufficient for the given application and specific tile being fixed. Any adhesive that forms a skin must be removed and fresh adhesive re-applied. Where solid bed fixing is required, as far as possible the adhesive under the tile should be free of voids and fully supported. To achieve this, in addition to trowelling the background, the tile may also require back buttering or trowelling. Clean any adhesive from the tile face and grout joints as work proceeds and before the adhesive has set.

Allow the adhesive to set before grouting using a suitable Kelmore grout. MoreBond Rapid C2 has been formulated to set in 3 hours when tested to the industry standard temperature of 20ºC. Please be aware that higher temperatures will shorten the set time and lower temperatures will extend the set time.
