Construction method:
First, the building must be kept dry, clean and free from oil pollution.
Two, before construction, should be applied to the surface of the bottom coating liquid, to dry the surface after the gap on both sides of the 10mm affixed to the 50mm wide protective tape,
To prevent the construction of excess polyurethane sealant, the structure of the surface pollution.
Three, the box of 1 barrels of white polyurethane sealant (A component) and 1 bags of black curing agent (B component) fully mixing, until there is no color difference so far.
(Note: due to different climate, B group should be more winter, Xia Jishao) A:B=100:8-12, should be tested before use.
Four, the polyurethane sealant mixing well with a putty knife or squeeze the glue gun into the slot and then fill compaction is larger than 10cm, width of putty scraping knife glue.
Five, after leveling tape, remove the protective tape, and within 24 hours should avoid water rushing rain.
(dry time less than 24 hours, 7 days before irrigation experiment, 28 days to meet all the performance.)
Six, prepared polyurethane sealant should be used up in two hours, otherwise it will be slowly solidified because of the ointment, resulting in construction difficulties, avoid waste
General name: double component urethane sealant (paste), building polyurethane glue (paste)

施工方法：一、建筑物必须保持干燥、干净、无油污。二、在施工前应先将底涂液涂于表面，待表面干燥后把缝隙的两边10mm处贴上50mm宽的防护胶带，以防施工中多余的聚氨酯密封胶把构筑物表面弄脏。三、把箱内1桶白色聚氨酯密封胶（A组份）与1袋黑色固化剂（B组份）充分搅拌均匀，直到无色差为止。（注：因气候不同B组份应冬季多、夏季少）A:B=100:8-12,用前应先做小试。四、把搅拌好的聚氨酯密封胶用灰刀或挤胶枪填入缝内压实填满，再用≥10cm宽腻子刀把胶刮平。五、施平胶后把防护胶带取下即可，24小时内应避免水冲雨淋。（表干时间≤24小时，7天后方可灌水试验，28天性能全部达到。）六、配制好的聚氨酯密封胶应在两小时内用完，否则会因膏慢慢固化而造成施工困难，避免浪费

通用名称：双组份氨酯密封胶（膏），建筑聚氨酯胶（膏）分类：a、按照流动性区分可分为非下垂型（N）和自流平型（L）两个类型；b、按照位移能力可分为25、20两个级别；c、按照拉伸模量分为高模量（HM）和低模量（LM）两个次级别。d、按组份又分为单组份聚氨酯密封胶和双组份聚氨酯密封胶

Sort:
According to a, liquidity can be divided into non droop type (N) and self leveling (L) type two;
B according to the displacement ability can be divided into 25, 20, two levels;
C is divided into two sub grades of high modulus (HM) and low modulus (LM) according to tensile modulus.
D, according to the components are divided into one component polyurethane sealant and two-component polyurethane sealant
