1	Coating material of interior wall
2	M7.5 cement mortar	0.93	15	5.8	1
3	Steam aerated concrete slab	0.146	200	27.7	2
4	M7.5 cement mortar	0.93	10	5.8	3
5	Graphite polystyrene plate	0.032	100	4.5
6	Adhesive mortar	0.93	5	5.8	4
7	Graphite polystyrene plate	0.032	100	4.5

According to the test method of JG/T210-2007 “Primer for Building Internal and External Walls,” the water permeability test result of the alkali resistant sealing primer for the external wall coating of this project is 0.1 ml, and the water resistance test result is 96 h without abnormality. Water vapor permeability coefficient refers to the water vapor partial pressure difference on both sides of a material with a thickness of 1 m under stable penetration conditions of 1 Pa, within 1 hour (the amount of water vapour that penetrates through an area of 1 square meter).
