摘要：
Summary:

防水卷材湿铺施工方法是指将用于非外露防水工程的湿铺防水卷材，用水泥凝胶（素水泥浆）与基层粘结的施工方法。适用于各类工业与民用建筑的屋面、地下室等防水工程，特别适用于防水等级较高、施工环境较差、潮湿、赶工期的防水工程。
Waterproof rolling material wet laying method is to refer to the wet spread waterproof rolling material used for non-exposed waterproof engineering, and the construction method of cement gel (plain cement slurry) and the base bond. It is suitable for waterproofing works such as roof and basement of all kinds of industrial and civil buildings, especially suitable for waterproofing project with high waterproofing grade, poor construction environment, damp and working period.

Method/procedure

1、基面清理：
1. Base cleaning:

清除基层表面杂物、油污、砂子，凸出表面的石子、砂浆疙瘩等应清理干净，清扫工作必须在施工中随时进行，并修补平整表面。尤其铲除排水口、烟囱、管壁上的水泥砂浆等附着物；
Remove debris, grease, sand and gravel on the surface of the grass. The surface of the stones and mortar should be cleaned. The cleaning must be carried out at any time during the construction and repair the flat surface. Especially to remove the cement mortar, such as water outlet, chimney and wall, etc.;

阴阳角采用水泥砂浆抹成圆弧角，阴角最小半径50mm，阳角最小半径20mm。基面若有明水，扫除即可施工。
The Angle of Yin and Yang is used to use cement mortar to be used as circular arc Angle, the minimum radius of the negative Angle is 50mm, and the minimum radius of yangjiao is 20mm. If the base surface has clear water, clean can be constructed.

2、配置水泥素浆：
2. Configuration of cement slurry:

按水泥：水=2:1（重量比）。先按比例将水倒入原已备好的拌浆桶，再将水泥放入水中，浸泡15～20分钟并充分浸透后，把桶面多余的水倒掉；然后加入水泥用量的5%～8%聚合物建筑胶（保水剂），用电动搅拌机进行搅拌，搅拌时间5分钟以上。
Cement: water = 2:1 (weight ratio). Pour the water into the ready mixing bucket, then put the cement into the water and soak for 15 ~ 20 minutes, then pour out the excess water. Then add 5 % ~ 8 % of polymer construction glue (water retention agent). Stir with electric mixer for more than 5 minutes.

3、弹基准线试铺：
3. Test base test:

根据施工现场状况，进行合理定位，确定卷材铺贴方向，在基层上弹好卷材控制线，依循流水方向从低往高进行卷材试铺。
According to the condition of the construction site, make reasonable positioning, determine the direction of the rolling material, play the coil control line at the base level, and follow the flow direction from the low to the high test.

4、撕开卷材底部隔离纸：
4. Slitting the bottom separation paper:

卷材试铺后，先将要铺贴的卷材剪好，反铺于基面上(即是底部隔离纸朝上)，撕剥去卷材隔离纸。撕剥时，已剥开的隔离纸宜与粘结面保持45～60度的锐角，防止拉断隔离纸，尽量保持在自然松弛状态，但不要有皱折。
After the test of the test, the rolling material is cut off, and the countertop is on the base (i.e., the bottom separation paper is up). When tearing, the separation paper that has been peeled off should be kept at an acute Angle of 45 ~ 60 degree with the adhesive surface to prevent pulling off the separation paper. Try to keep it in a state of natural relaxation, but not wrinkle.

5、卷材铺贴：
5. Coiled material:

滚铺法：将卷材对准基准线试铺，在约5m长处用裁纸刀将隔离纸轻轻划开，注意不要划伤卷材，将未铺开卷材隔离纸从背面缓缓撕开，同时将未铺开卷材沿基准线慢慢向前推铺。边撕隔离纸边铺贴。铺贴好后再将前面试铺剩余的约5m长卷材卷回，依上述方法粘贴在基层上。
Roll shop law: the coil on the baseline test, in about 5 m strengths with a paper knife isolation paper gently open, pay attention not to scratch coil, will not spread out coil isolation paper tear slowly from the back, at the same time will not spread out coil slowly forward spread along the baseline. Strip the edges of the paper. After the shop is tiled, the remaining about 5m long rolls will be rolled back, and paste on the grass roots.

抬铺法: 把已剪好的卷材反铺于基面上（即是底部隔离纸朝上），待剥去卷材全部隔离纸后，再将水泥素浆刮涂在卷材粘结面和基面待铺位置，然后分别由两人从卷材的两端配合抬起，翻转和铺贴在待铺位置上。卷材与相邻卷材之间为平行搭接，待长、短边搭接施工时再揭除上下卷材搭接隔离膜。
Lift shop law: cut the has good coil the shop is the base surface (i.e., is at the bottom of the isolation of paper up), after being all isolation strip coil paper, then cement slurry coating in coil bonding surface and reference plane to shop location, and then respectively by two people cooperate up from the ends of the coil, turn and the shop is stuck on the opening position. The coil is parallel to the adjacent coil, and when the long and short side lap joints are constructed, remove the upper and lower coiled insulation film.

6、辊压排气：
6. Roller pressure exhaust:

待卷材铺贴完成后，用软橡胶板或辊筒等从中间向卷材搭接方向另一侧刮压并排出空气，使卷材充分满粘于基面上。搭接铺贴下一幅卷材时，将位于下层的卷材搭接部位的隔离纸揭起，将上层卷材对准搭接控制线平整粘贴在下层卷材上，刮压排出空气，充分满粘。
After the rollers are finished, use soft rubber plates or rollers to lift the air out from the middle to the side of the coil, and make the coil fully adhere to the base surface. Lap when the shop is stuck under a coil, will be located in the lower coil isolation paper have overlapping parts, the upper coil on the lap line smooth paste on the lower coil, scraping the pressure discharge air, fully filled with glue.

7、搭接封边、收头密封：
7. Lap seal and end seal:

单面粘卷材搭接边施工：短边相邻卷材之间为平行搭接，用HNP胶粘带盖条加温粘结（屋面胶粘带盖条宽度100㎜，地下室胶粘带盖条宽度160㎜）。长边为加温自粘搭接,搭接宽带不小于80mm。大面积铺贴完成后24小时再进行搭接边施工，施工时清理干净搭接边部位的泥浆及灰尘，再揭除上下卷材搭接隔离膜（短边不用撕隔离膜），用热风枪边加温边粘结。
Single stick coil lap construction: short for parallel overlap between adjacent coil, cover the heating bonding with HNP adhesive tapes (roofing adhesive tape cover strip width 100 ㎜, basement adhesive tape cover strip width 160 ㎜). The long side is the heating self-adhesive, the lap band is not less than 80mm. Large area of the shop is stuck to lap 24 hours after the completion of construction, construction clean lap side parts of the mud and dirt, and jie in addition to coil lap isolation membrane (short side don't tear isolation membrane), with a heat gun heat while bonding.

8、成品养护及保护：
8. Product maintenance and protection:

晾放24小时至48小时（具体时间视环境温度而定，一般情况下，温度愈高所需时间愈短）。高温天气下，防水层应防止暴晒，可用遮阳布或其他物品遮盖。
Leave 24 hours to 48 hours (depending on the temperature of the environment). In hot weather, the waterproof layer should prevent exposure to the sun and cover with sunshade cloth or other items.
