Construction Process of XPS Extruded Board Exterior Wall

1、 The base course wall shall be treated. The wall must be cleaned and leveled. For the parts with pits and bulges, the pits shall be filled with cement and the bulges shall be removed. In order to increase the bonding force between the extruded board and mortar, special interface agent shall be painted on the surface of the extruded board.

2、 Prepare the materials, prepare the adhesive paste, and connect the adhesive and water according to 5:1 Mix and place five It can be used in minutes two Use up within hours. In the construction process, not every piece can be made according to the standard size, so it should be equipped with electric heating wire to cut at any time to facilitate the construction of extruded boards.

3、 Paste the extruded board Extruded board for exterior wall Conduct interface treatment to increase cohesiveness, apply adhesive paste on the extruded board, drag and scrape it once with a special saw tooth trowel, and scrape off the excess adhesive paste between the saw teeth. After the thick treatment, paste the extruded board flat on the wall and slide it in place. When pasting, it should be gently and evenly squeezed, and a length should be prepared at any time 2m To flatten.

4、 When pasting extruded boards, they should be laid in staggered joints, with half of the board length staggered. The construction shall be carried out quickly. Before the extrusion board is installed in place, the adhesive mortar shall not be skinned. The joints of the extrusion board shall be tight and flat. The adhesive mortar shall not be applied on the side of the extrusion board.

5、 The extruded plates at the door and window openings and corners shall be cut out of the openings with a whole extruded plate, without splicing. The extruded plates shall be pasted thick and spaced twenty-four After bonding and fixing for hours, polish to prevent displacement and dislocation of extrusion plate.

6、 Install the fastener and paste the extruded plate twenty-four After 24 hours, drill holes with an impact drill and install plastic expansion anchor bolts according to the design requirements.

7、 Lay the mesh cloth, use a stainless steel trowel, and evenly apply a layer of plaster mortar with an area slightly larger than that of a mesh cloth on the surface of the extruded plate, with a thickness of 3mm On the left and right, press the mesh cloth into the wet plaster mortar until the mesh cloth is completely covered and the surface is polished.

XPS Plastic extruded board Installation precautions:

one The bonding operation of extruded board shall be rapid, and the bonding glue shall not be skinned

two , extruded board pasting twenty-four After hours, install the expansion anchor bolt of the extruded plate

three Do not lay grid cloth in the rain

four , the grid cloth shall be continuous, and the width of wall wrapping from each side in both directions shall not be less than 200mm Reinforce the docking arrangement of mesh

five , curing after construction twenty-four In cold and humid climate, the curing time should be extended appropriately.
