Overview
KingTile C5G is a one component blend of cement, well graded aggregates and special additives used to create screeds for the installation of external block stone paving and bricks, it is also applied as a thick-bed screed followed by a slurry layer to fix stones, granites, marbles or any other type of tiles.
KingTile C5G is used along with KingFill S10 grout to create architectural stone paving with high durability and resistance to environmental conditions.
Where to use
KingTile C5G is used as an installation screed for natural stone, granite and marble architectural flooring in public areas, roads, pavements, parking lots and pedestrian crossings. It is suitable for use with:
- Self-locking blocks.
- Small blocks.
- Bricks.
- Pre-casted stones, ceramic, marbles, granite and natural stones.
- Architectural pavers.
Why use it
- High compressive strength.
- Good water resistance.
- High bond strength.
- Ready mixed, just requires the addition of water.
- Suitable for internal and external applications.

How to use
Surface preparation
All surfaces must be clean, dry and free from dust, oil, grease, paints or any loose material. Concrete and cement based substrates must be sufficiently cured and dimensionally stable. Allow time for shrinkage and structural strain movements. Curing compounds and sealers, if present, must be removed by mechanical means.
Priming
It is not usually necessary to prime absorbent surfaces. However, to ensure satisfactory bonding, the prepared surface should be dampened down with water.
Mixing
Mix the 25 kg bag of KingTile C5G with 2 - 2.5 litres of water using a heavy duty slow speed drill-paddle assembly or concrete mixer for mixing. Mix properly until a homogenous mix with zero-slump consistency is achieved. The amount of water should be minimal to attain the optimum properties of the bedding screed.
Note: It is recommended that in hot weather application, chilled water is used to extend the working time of the mixed material.
Application
Spread the mixed material over the surface in a uniform thickness, but in small areas at a time. Make sure that the consistency of the mortar remains the same in order to maintain its characteristics.
If the flooring is made from slabs or large non porous tiles, before laying the stone on the fresh KingTile C5G installation layer, apply a layer of bonding slurry made by mixing 1 part KingBond SBR100: 2 parts OPC cement by weight. Pour the properly mixed slurry over the levelled bedding screed whilst wet at a thickness of 2 to 3 mm and immediately install the tile or stone.
Lay the stone in the pattern required with a 5 to 15 mm gap around each piece. After laying the stone on the zero-slump consistency mix, wet the flooring with water to hydrate the installation layer and tamp the surface of the stone.
Before pouring the grouting mortar into the joints, sprinkle the surface of the stone with water, clean the joints and remove any freestanding water and uneven or loose areas.
For grouting the joints, KingFill S10 is recommended to be applied the same day of installing the stone, before the installation layer has completely set, at that is in order to form a monolithic flooring.
If required by the surrounding conditions (high temperatures, rain, low temperatures, etc.), once grouting has been completed, protect the flooring for at least 12 hours after application with a suitable protective or anti-evaporation system, in order to prevent it from drying out too quickly and to keep the product at the correct temperature.
Protect the tiled surface from light traffic for at least 24 hours.
Cleaning
All tools should be cleaned immediately after finishing by water.
