How to increase the open time of tile adhesive to 30 minutes?

 

[Shamil]

If you want to moisturize, add more cellulose ether and a water-reducing agent.

 

[Ankur]

Add cellulose ether to 3.5 or 4 kg. Make sure the cellulose ether is high quality.

It will affect the open time if the amount of redispersible polymer powder is too large.
There is a difference between retarding and open time.
Do you want the open time to be 30 min? Use 200,000 pure cellulose ether 3.5-4kg; it should work.

If the single cellulose ether is above 3.5 and cannot be cooled for 30 minutes, then replace it. Generally, the average addition amount is wood fiber, redispersible polymer powder, starch ether, and it is not a problem to let it cool for 30 minutes.

It is tough to use only a single cellulose ether to reach 30 minutes, and make the strength index reaches the standard. Only a few brands can achieve it, and the impact on the strength is also significant.

If your original strength is 0.5MPa and only 0.4MPa with 30 minutes open time, increase the original strength to 0.6MPa and add some redispersible polymer powder, then nothing to be worried.
