环氧地坪基本要求和时间要求
Concrete and Substrate requirement and time limit for epoxy flooring
一、 对砼的要求：Concrete requirement
1、 砼等级C25 以上；Concrete level ≥C25
2、 原浆结面（不得补浆、撒干水泥）
Magma admission(Use concrete surface smooth concrete puree. Do not patch
slurry secondly or broadcast dry cement)
3、 每2m 不得大于5mm 平整度。Surface roughness≤ 5mm/2m
4、 地坪养护时间25 天~28 天，（如加早强剂、减水剂）可在20 天左右强化、硬化；
Concrete curing time: 25-28 days; (If add early strength agent of concrete, the
curing time may be 20 days)
5、 地坪含水率不得大于4%。Flooring moisture content≤4%
二、 环氧砂浆施工基面要求Substrate requirement for epoxy screed
application
混凝土基面必须密实（层厚不低于70mm）和有足够的抗压强度（最小25 N/mm2），
最小抗拉强度为1.5 N/mm2。
The concrete substrate must be sound (Layer Thickness≥70mm) and of sufficient
compressive strength (minimum 25 N/mm2) with a minimum pull off strength of 1.5
N/mm2.
混凝土基层下须设置防水层，否则存在水汽上升导致环氧层起泡、脱落风险。
A waterproofing layer must be installed under the concrete base，or vapor going up
will result in epoxy layer bubbling and delamination.
基层须干燥，含水率≤4%，测试方法：Sika®-Tramex仪或CM测量法
Substrate needs to be dry, moisture content ≤4%. Test method: Sika®-Tramex meter
or CM - measurement.
若防水层被破坏或基面含水率＞4%，建议施工2 mm西卡环氧自流平水泥层（Sikalfoor
81 EpoCem系统）作为防潮层。
If the waterlayer is broken or moisture content ＞4%, 2 mm Sikafloor 81 EpoCem
system is recommended to be applied as a moisture barrier.
基面必须清洁、无任何污染物，如：灰尘、油、油脂、涂层和表面处理等。
The substrate must be clean and free of all contaminants such as dirt, oil, grease,
coatings and surface treatments, etc.
三．施工条件Application Conditions
Substrate Temperature: +10℃ min. / +30℃ max.
基面温度：最低+10℃/最高+30℃
Ambient Temperature +10℃ min. / +30℃ max.
环境温度：最低+10℃/最高+30℃
Relative Air Humidity: 80% R.H. max.
相对空气湿度：最高80%相对湿度
Dew Point: The substrate and uncured floor must be at least 3℃ above dew point to
reduce the risk of condensation or blooming on the floor finish.
露点：基面和未固化的地面温度必须至少高于露点3℃，以防水汽凝结形成斑点。
四. 施工工期与养护时间 Time limit for project and Curing time
1、 材料采购周期为15 天~20 天；Lead time for material:15-20 days
2、 材料进场如8000 ㎡，施工周期为15 天；
After the materials arrive the site, the application time is about 15 days for
8000m2
3. Curing Details 养护细则
Temperature 温度 Foot traffic 可步行 Light traffic 轻度荷载 Full cure 完全固化
+10℃ ～30 hours ～5 days ～10 days
+20℃ ～24 hours ～3 days ～7 days
+30℃ ～16 hours ～2 days ～5 days
Note: Times are approximate and will be affected by changing ambient conditions.
备注：以上时间为约值，并会随周边环境变化有所改变
