防水速凝劑可使水泥快速凝結(jié)，凝結(jié)時間可任意調(diào)節(jié)，由數(shù)十秒至數(shù)分鐘，由摻加量來加以控制。摻加本品的水泥砂漿或凈漿對于磚，混凝土有較強粘結(jié)力，可用于墻面，地面堵漏，抗?jié)B等工程中。
使用方法：
1、 堵漏水裂縫及孔洞：
應(yīng)配制防水膠泥，凝結(jié)時間 40 秒左右，用手壓入縫（洞）中，待其凝固后松手即可。
2 、五層防水抹面
第一層素灰一遍，水泥：水：防水劑為 1:0. 3 ～ 0.35:0.01 ，要先抹素灰一道 1 ㎜厚，用鐵抹子壓 5 ～ 6 次，隨即用素灰找平約 1 ㎜厚，然后用毛刷蘸水，按順序刷勻，立即做第二層。
第二層的配合比，水泥：水：砂防水劑為 1 ： 0.4 ～ 0.5:2 ～ 2.5:0.01 ，均勻抹一層約厚 5 ㎜，用苕帚掃成條紋，隔 24 小時后，再做第三層。
第三層素灰壓一道厚 2 ㎜，配合比同第一層。
第四層同第二層，但抹后不掃毛，抹后 3 ～ 4 小時用鐵抹子壓 2 ～ 3 遍，待吃水后，還有點潮濕，但不粘手，即可做第五遍。
第五層刷素灰層一道厚 1 ㎜，配合比同第一層，刷時要均勻，吃水后，再用鐵抹子壓 3 ～ 4 遍。
注意事項：
1 、第一遍基層應(yīng)事先清理干凈，如有凸凹不平，應(yīng)事先處理，防止起鼓。
2 、每道不得留有明顯接縫。
Waterproof Set Accelerator
The waterproof set accelerator enables concrete to set fast ； the duration for setting is controllable ， from scores of seconds to several minutes, which is determined by the quantity of the agent added thereto. The cement mortar or neat cement paste to which the agent has been mixed possesses a rather strong adhesion to bricks, concrete ， which can be used for wall surface ， floor leakage and water proofing.
Application ：
1 、 Caulking the leaky cracks & holes
Waterproof mastic is to be mixed ， the setting time of which is about 40 seconds ． Use the hand to press the mixture into the crack or hole, aIlow the mixture to set before releasing the hand ．
2 、 Five-layer waterproof trowelled surface
For the first layer of neat cement paste ． the ratio of mix of cement ． water ．＆ waterproof agent should be 1:0 3 ～ 0.35: 0.01 A 1 mm thick layer of such neat cement paste must be applied first ， pressed with a trowel for 5 or 6 times ， and then leveled with the paste to a thickness of 1 mm ： use a b rush which has been dipped in water to brush the surface until it becomes even ； and then set out to do the second layer at once ．
For the second course ． the ratio of cement ． water ． sand ＆ waterproof agent is to be 1:0. 4 ～ 0.5:2 ～ 2.5:0.01 ； a uniform layer of such an admixture should be applied to a thickness of 5 mm ． and broom b rushed into strips ； allow it to set for 24 hours before doing the third layer ．
For the third course ， the ratio of mix is the same as that for the first layer and the thickness of neat cement paste is to be 2 mm
For the fourth course ， the ratio of mix is the same as that for the second layer ， however ， no broom-brushing is to be made ， instead ， allow it to set for 3 to 4 hours and then use the trowel to press it for 2 or 3 times ， wait for the surface to dry up a bit ， but is still moist ， yet not sticky, before the fifth layer can be started ．
The fifth course is to be finished with a l mm thick layer of neat cement paste ， its ratio of mix being the same as that for the first layer ； the application should be even ， wait for the area to dry up a bit ． and then use the trowel to press it for 3 or 4 times ．
Caution ：
1 、 For the base course ， the area should be cleaned up ， and the uneven spots treated ． To avoid swells
2 、 No apparent joint should be left for each course of application ．
