5.4. base wall should be solid flat, dry surface, no cracking, hollowing, loose or efflorescence, the bond strength of cement mortar layer, flatness and verticality shall be in accordance with the (code for construction quality acceptance of building decoration) ordinary plastering engineering quality requirements in GB50210.

6. rock wool board exterior insulation construction period, the grass-roots and construction environment temperature is less than 5 degrees, shall not be construction. It is not allowed to work in gale weather or rain or snow weather above grade five. During construction and after construction, effective measures should be taken to prevent rain erosion and hot sun exposure, and timely protection layer should be made. Such as the construction in the sudden rain, measures should be taken to prevent the rain scour wall; winter construction should take measures in accordance with the relevant standards.

Before the construction of the 7. large areas, the same material should be used on the spot, the construction practice and the process of making the sample wall, and the construction can be carried out after confirmation by the parties concerned.

8. with rock wool board construction, the operator should wear goodPPEDo well occupational health protection, and pay attention to construction safety.

9. mineral wool board external insulation system must be inspected materials should be sent to the qualified testing institutions for testing, testing qualified before use.

10. rock wool board paste should adopt the stick method or point sticking method, the coating area should not be less than 50%. Rock wool board wipe the adhesive after the first heat insulation plate and the lower end of the paste, rock wool board from the bottom to the top along the horizontal direction of the transverse paving, and should take the edge border anchor slab should be close to nature, plate gap should not be more than 2mm, such as the width of 2mm, and should be filled with insulation materials, the adjacent panel should be flush plate height shall not exceed 1.5mm.

Through the pipeline and the 11. member all up to the rock wool board, its export parts using the same materials filled after sealing treatment.

Installation steps
1, according to the size of rock wool composite board on the wall with the use of 6 steel expansion bolt anchor card (composite plate transverse arrangement, each board two pieces of cards, composite plate vertical layout, the board on the left and right sides of a card);
2, with adhesive mortar bonding rock wool composite board, stick point sticky; wipe 3~5 thick anti crack mortar, inner pressure a glass fiber mesh cloth, in order to ensure solid and reliable. The number of fixed parts should be set according to the design specification.
3, wipe the bottom polymer mortar:
(1) the preparation of the polymer mortar is the same as the special binder.
(2) the prepared polymer mortar is evenly coated on the rock wool board, with a thickness of 2mm.
4. Press in mesh cloth:
(1) the mesh cloth should be cut according to the length of the working face, and the lap width should be set. The cutting of mesh cloth should be carried out along warp and weft direction.
(2) in the door and window and other openings around the grid cloth flip bag, four corners should be attached to a grid cloth to strengthen, the whole grid cloth should be around the entrance flip bag and additional mesh cloth.
(3) both the front and the sides of the rock wool board at the openings and the grid cloth flip sides are coated with polymer mortar (only allow the rock wool board end to wipe the polymer mortar at the end). The grid cloth is thrown out along the plate thickness and pressed into the polymer mortar.
