This covering has a character of soundly fireproof, vibration-resisting, impact-resisting and can insulate noises and heat conduction effectively. This covering is suitable for machinery spaces which usually have much noises and vibration as well as Class A-60 damp cabin fire decks.

Material Name		Packing	Usage
Suface	Powder (Component A)	13kg bag	1 bag/㎡
	Filling(Component B)	15kg bag	1 bag/㎡
Steel mesh		Ф3，1100×2000mm	0.5unit/㎡
Bottom	Powder (Component A)	10kg/bag	1 bag/㎡
	Filling(Component B)	4kg/bag	1bag/㎡

△Bottom covering：1 bag of powder (Component A) and 1 bag of filling (Component B) and adding about 14kg clean water。

Firstly feed 1 bag of filling (Component B) into the agitator together with about 50% of the required water amount water and stir it, when the component B has been moseturized, add the setting 1 bag of powder (Component A) and the rest 50% water and continue mixing and stirring, the covering is ready for application when it is mixed evenly and can be a mass easily by hand。

△Suface covering：1 bag of powder (Component A) and 1 bag of filling (Component B) and adding about 5-6kg clean water。

Feed setting powder and filling into the agitator, stir and mix it, and the add the required amount water, and continue stirring, the covering is ready for application when it is mixed even state like thick mud。

△Steel deck must be flatted。

△All the dust, water and oil smudges on the deck should be cleared, and then derusted according to the St2 of CB3230。

△The stirred mortar of lightweight battom covering is spread on a steel deck. A long wooden ruler should be used to float the covering to the thickness as required.The iron plate should be used again to press and smooth the surface of the layer.

△Steel mesh is laid out. The overlap width should not be less than 100mm, And the overlaps must be fastened with galvanized iron wire。

△The covering mortar stirred is spread on the film. A long wooden ruler should be used. While the layer is being leveled, the steel mesh must be lifted up 5~10mm. And then the layer should be pressed with iron plate into a dense structure. The layer thickness is 20mm, and its surface should be smoothed。

△ The place of storing should be at a cool, ventilated place in avoidance of being exposed to the rain or strong sunshine. It is forbidden to damp the materials。

△The appropriate temperatures are between 5~30℃. If the environmental temperature is higher or lower than those above mentioned, the necessary measures to cool or warm should be taken。

△If the components are stirred by hand, or the environmental temperature is too high, the viscosity of deck covering will be higher as well. In this case, clean water can be added properly. But too much water will directly affect the strength of the material。

△After the laying of covering , the layer must be under necessary conservation, such as spraying setting solution or water. Or its surface is covered with some airtight material。

△Quality guarantee period is 6 months.
