底涂，是环氧地坪漆施工工艺中最重要的一步，只有这一步做好了，才能够继续在基面上面进行下一步涂装。所以，一般对用于环氧地坪涂装的底漆的要求为：应与基材有良好的附着力；本身具有良好的机械强度；对底材具有良好的保护性能和不起不利的副作用；能为以后的涂层创造良好的基础，不能含有渗入上层涂膜引起弊病的组分；更要具有良好的施工性和干燥性。

Primer is the most important step in the construction process of epoxy floor paint. Only when this step is completed can the next coating be continued on the base surface. Therefore, the general requirements for primers used in floor coating are: good adhesion with the substrate; good mechanical strength; good protection against the substrate and no adverse side effects; can create a good foundation for future coatings, can not contain the components of the defects caused by infiltration into the upper coating; Better construction and dryness.

涂布底漆时一般应注意要在表面处理以后严格按照规定的时间及时涂布底漆。还要根据底漆品种规定的条件在底漆干燥后规定的时间范围内涂下一道漆。过早涂布可能引起咬底及底漆中溶剂挥发困难导致漆膜干燥时间延长‘固化不良、鼓泡等情况；涂布达迟可能引起层间附着不良，且过迟涂布易由于粉尘积累或其他污染影响表观质量。为增加下一道涂层与底漆间的附着力，可在涂布前将底漆打磨。

Primer coating should generally pay attention to the surface treatment in strict accordance with the prescribed time and timely coating primer. A paint should also be applied within the time limit specified after the primer is dried according to the conditions stipulated in the primer. Early coating may cause underbite and difficulty in solvent evaporation in primer resulting in prolonged drying time `poor solidification, bubbling and other conditions; late coating may cause poor adhesion between layers, and late coating is easy to affect the apparent quality due to dust accumulation or other pollution. To increase adhesion between the next coating and primer, the primer can be ground before coating.

涂布底漆的方法一般可采用辊涂、刷涂和喷涂。刷涂施工效率较低，一般在边角处施工采用。最常用的是辊涂，效率高。

Coating primers are generally made by roller coating, brush coating and spraying. Brush construction efficiency is low, usually in the corner construction. The most commonly used roller coating is highly efficient. 封闭底漆施工：

Construction of closed primer:

用刷涂、辊涂或喷涂的方法施工封闭环氧地坪漆底漆一道至两道，两道之间的间隔时间在8h以上，但不能大于48h。对于旧地面，应增加一道底漆。底漆施工时应注意涂布均匀，涂膜无明显的厚度差异，防止漏涂。用辊涂法施工应注意余料堆积情况。底漆封闭不完全（漏涂）时，会发生附着不牢、涂膜起泡等现象。

Use brush, roll or spray to apply one or two closed floor primers. The interval between the two primers is more than 8 hours, but not more than 48 hours. For old ground, a primer should be added. Attention should be paid to uniform coating when priming is applied, and no obvious difference in thickness is observed to prevent leakage. Attention should be paid to the accumulation of residual materials by roller coating method. When the primer is not fully sealed (leak coating), it will cause adhesion, coating and bubbling.

1.底漆漆膜厚度根据底漆品种确定，应注意控制。表面无浮尘及松散砂粒。

1. primer paint film thickness should be determined according to primer varieties, and attention should be paid to control. There is no floating dust and loose sand on the surface.

2.含颜填料的底漆在使用前和使用过程应注意搅拌均匀

2. primer with pigments and fillers should be evenly stirred before use and during use.

3.注意遵守干燥的规范。在底涂上如涂含有强溶剂的涂料时，底漆必须干透，以免出现咬底等漆病。

3. pay attention to the drying specifications. Primers must be dry when priming is applied to paints containing strong solvents, so as to avoid biting diseases.

4.增加下一道涂层与底漆间的附力，可在涂布前将底漆打磨。

4. increase the adhesion between the next coating and primer, so that the primer can be ground before coating.

5.要在漆前表面处理以后严格按照规定的时间及时涂布底漆。还要根据底漆品种规定的条件在底漆干燥后规定时间范围内涂下一道漆。过早涂布可能引起咬底及底漆中溶剂挥发困难导致漆膜干燥时间延长、固化不良的情况；涂布过迟可能引起层间附着不良，且过迟涂布易由于粉尘积累或其他污染影响表观。

5. before coating the surface, the primers should be coated in strict accordance with the prescribed time. A paint should also be applied within the specified time limit after the primer is dried according to the conditions stipulated in the primer. Early coating may cause priming and solvent evaporation difficulties in primers lead to prolonged drying time and poor solidification of the film; too late coating may lead to poor adhesion between layers, and too late coating may easily be affected by dust accumulation or other pollution.

底漆稀释按照说明书和环氧树脂地坪漆施工需要进行，控制好比例，严禁过量稀释。

Primer dilution according to the instructions and epoxy resin floor paint construction needs, control the proportion, prohibit excessive dilution.

须在基面充分干燥、无异物的情况下进行，对地面必须进行清扫处理，对不符合要求的地面应及时向项目经理反映。

The ground must be cleaned when the base is fully dry and there is no foreign matter. If the ground does not meet the requirements, it should be reported to the project manager in time.

环氧树脂地坪漆材料开桶后，应充分搅拌均匀再进行使用。

When the epoxy floor paint is opened, it should be fully stirred and used again.

先刷边角及不易棍涂的部位，再由上往下进行大面积施工，不易吸料的环氧地坪用毛刷点刷环氧树脂地坪漆底涂。

First brush the edges and corners and the parts which are not easy to stick, and then carry out large-scale construction from top to bottom, not easy to absorb material for the floor with brush point brush epoxy resin floor paint primer.

涂刷时，桶内必须设置滚板，棍筒和毛刷蘸料后必须在滚板上舔料后方可进行施工。

When painting, the barrel must be equipped with rollers, sticks and brushes dipped in the material must be on the rollers after licking material can be constructed.

若有毛刷毛或棍筒毛沾在墙上，应及时处理。

If brush hair or club hair is stained on the wall, it should be dealt with promptly.

由于溶剂挥发较快，若施工过程中底涂变稠影响施工，可适量添加溶剂，不过一般情况下，不建议采取这种办法。

Due to the rapid volatilization of solvents, if the thickening of the primer during construction affects the construction, the appropriate amount of solvents can be added, but in general, this method is not recommended.

检查地面是否有漏涂现象并加以修补。

Check if there is any leakage on the ground and repair it.

重涂时间一般大于6-8小时。

The repainting time is usually greater than 6-8 hours.

环氧地坪漆施工效果涂布率满足要求;不允许有漏涂现象和流坠、明显的接搓，做到棍涂均匀。若实际涂布率与该涂布率相差较大，应报请项目经理。

Epoxy floor paint construction effect coating rate to meet the requirements; do not allow the phenomenon of leakage coating and flow, obvious rubbing, to achieve uniform stick coating. If there is a big difference between the actual coating rate and the coating rate, it should be reported to the project manager.

环氧树脂地坪漆施工的步骤中，底涂是至关重要的一点，只有将基面封闭好了，才能够进行下一步涂装，如果底涂没有做好，就算后面的工艺做得再好，都将功亏一篑。

In the construction of epoxy floor paint, primer is a crucial point. Only when the base surface is sealed, can the next coating be carried out. If the primer is not done well, even if the later process is done well, it will be lost.

其他方面要注意的：

Other aspects should be noted:

腻子修补：

Putty Repair:

对水泥基层存在的凹坑，用商品环氧腻子或用底漆和细石英砂配置的环氧砂浆填平，在固化成膜后打磨平整。

For pits in cement base, fill them with commercial epoxy putty or epoxy mortar with primer and fine quartz sand, and then grind them smoothly after solidification.

中层涂料施工：

Middle level coating construction:

对于厚膜型涂料，中层涂料施工时可采用镘刀镘涂。由于涂料中使用的石英砂较多，一般情况下刮涂后涂膜不会出现明显刮刀痕迹，但如果石英砂加入量过大，刮痕明显时应辊压一次。涂装间隔如果大于48h，应进行打磨后再进行下道涂料的施工，以保证层间黏结力。

For thick film coatings, trowel trowel can be used in middle coating construction. Due to the use of more quartz sand in the paint, the film will not appear obvious scratch marks under normal circumstances, but if the addition of quartz sand is too large, scratch obvious should be rolled once. If the coating interval is greater than 48 hours, the next coating should be applied after grinding to ensure interlaminar adhesion.

面涂料施工：

Surface coating construction:

根据环氧耐磨地坪涂料的种类，面涂料可以采用刷涂或刮涂施工。对于厚膜型涂料，按配比要求将两组份涂料混合均匀，待熟化后使用1mm刮板刮涂涂料。刮涂时应尽量保持厚膜均匀，无漏涂现象，无明显余料。刮涂时，刮刀的移动速度应均匀，刮刀与地面平面夹角为30°左右，以保证涂膜厚度。刮涂道数根据厚度要求而定。普通环氧涂料则可以采取刷涂方法施工。面涂料施工时两道之间的间隔时间应在18h以上，但不能大于48h。配置好的涂料应尽快用完，以防止涂料的黏度升高，涂料中的气泡难于排出。

According to the types of epoxy abrasion resistant floor coatings, the surface coating can be constructed by brush or scraping. For thick film coatings, mix the two components evenly according to the proportion requirements, and use 1mm scraper coating after curing. During scraping, thick film should be kept as uniform as possible without any leakage. When scraping, the moving speed of the scraper should be uniform, and the angle between the scraper and the ground plane should be about 30 degrees to ensure the film thickness. The number of scraper passes depends on the thickness requirements. Ordinary epoxy coatings can be constructed by brush method. The interval between the two surfaces should be above 18h, but not more than 48h. The coatings should be used up as soon as possible to prevent the viscosity of the coatings from rising and the bubbles in the coatings are difficult to discharge.

环氧地坪养护：

Epoxy floor maintenance:

面涂料施工完，并完全固化后，一般应在面涂料施工24h以上方可上人，72小时后方可重压。（25℃为准，低温开放时间需适度延长。）

After the surface coating has been applied and completely cured, it should be applied for more than 24 hours before it can be applied, and 72 hours after it can be repressed. (at 25 C, the opening time at low temperature should be extended moderately).
