有些瓷砖粘结剂施工完两三天后仍然没有强度，用手按压时感觉发软，这是为什么呢?下面济南石膏粉厂家为您分析，可能是以下几点原因：

Some ceramic tile adhesives still have no strength after two or three days of construction, and they feel soft when pressed by hand. Why is this? Jinan gypsum powder manufacturer will analyze the following reasons for you:

1、冬季温度低，未采取保护措施，瓷砖粘结剂难以正常硬化。瓷砖粘结剂施工温度建议在5-35℃之间，冬季施工时应注意采取保暖措施。

1. In winter, the temperature is low and protective measures are not taken, making it difficult for the ceramic tile adhesive to harden normally. The construction temperature of ceramic tile adhesive is recommended to be between 5-35 ℃. During winter construction, thermal insulation measures should be taken.

2、瓷砖粘结剂施工厚度过大，其良好的保水性造成内部不能正常硬化，找平铺贴厚度建议在3～5mm佳，大不要超过8mm。

2. The construction thickness of the ceramic tile adhesive is too large, and its good water retention property causes the interior to not harden normally. It is recommended that the thickness of the leveling and paving be 3 to 5mm, and the maximum thickness should not exceed 8mm.

3、基层或玻化砖吸水率过低。

3. The water absorption of the base layer or vitrified brick is too low.

4、基层过于干燥，施工前应往墙面喷洒水进行润湿，避免水分散失过快，导致瓷砖粘结剂强度上不来。

4. The base layer is too dry, and before construction, water should be sprayed on the wall to moisten it to avoid excessive water loss, which may lead to poor strength of the ceramic tile adhesive.

4、瓷砖的规格过大。

4. The specification of the ceramic tile is too large.

5、有些双组分的瓷砖粘结剂在使用时，所选乳液和干粉搭配不当，应选用品质较好的瓷砖粘结剂，并严格按照使用说明进行施工。

5. When using some two-component ceramic tile adhesives, the selected lotion and dry powder are not properly matched, so ceramic tile adhesives with good quality should be selected and constructed in strict accordance with the instructions.
