1 Introduction:

Glass bead insulation dry-mixed mortar is a new type of insulation material, with high strength, light weight, thermal insulation, thermal insulation, good electrical insulation properties, wear-resistant, corrosion-resistant, radiation significantly. Insulation dry mortar has the following advantages: water-resistant, high temperature resistant, will not mildew corrosion, strong bond, good weather resistance, not hollowing, no cracking, flexibility, shrinkage of small, non-toxic, environmentally friendly. Insulation dry mortar is applied to energy saving by 50% and 65% of the hot summer and cold in winter and hot in summer and warm in winter, moderate for building, renovation and expansion of the public and civil construction of the external walls, exterior insulation, roof insulation, energy-saving projects.

4, the construction process:
The first step: check the grassroots, do ash cake hanging perpendicular, the grass-roots level should be solid, basic flat. According to the design requirements of the thickness of the insulation layer, hanging vertical line to do the ash cake, to ensure insulation thickness and surface roughness.

Step 2: Mixing insulation mortar, insulation mortar thin batch proportioning, mixing evenly first batch knife batch of thin insulation mortar thickness of 3-5mm appropriate (this procedure is equivalent to the interface processing), and then graded wipe coated insulation mortar, the thickness of each pass to no more than 10mm suitable, until it reaches the design thickness. Wiping finished last again after using aluminum alloy foot 刮平.

The third step: roller coating water repellent, pressed into alkali-resistant fiberglass mesh, batch coated waterproof anti-cracking mortar pending insulation layer dry, roller coating penetration waterproofing agent (painted within 24 hours after to avoid rainfall). First full batch of waterproof insulation mortar waterproofing agent anti-cracking mortar coated alkali-resistant fiberglass mesh cloth and batch knife pressed into the mortar, until the first over and glue table dry again after a full batch of mortar . Alkali-resistant fiberglass mesh is required between lap 100mm.

Step 4: batch coated elastic putty, roll coating exterior paint. First in water repellent mortar surface cracking batch of coated flexible putty, then use the batch knife alkali-resistant fiberglass mesh cloth pressed into the putty, putty table again before be dry again full of putty, putty full coverage alkali glass fiber mesh cloth. Until the putty dry sandpaper roll coating.
