With the exception of adding 1-2 cups of extra water, I am following the directions exactly. Stir for 5 minutes, let it stand for 5-10 minutes and restir.
It trowels on fine after adding the extra water. I also used the Versibond in our bathroom, and it worked fine. The Versibond took the amount of water it called for to stir it up.
The comparison with Versibond and the SpectriSet is somewhat different. The SpectreSet is so much dryer. I don't think the pot life would be the 2-4 hours the manufacturer says it would be if made that dry. Plus, it was making my 1/2 inch drill labor way too much. The dryer mixture was also harder to handle and apply.
I am trying to bring it to that stage where the thinset is just at the cake frostning-like state. Otherwise, the thinset was going to be dry, dry, dry.
I am only mixing a 1/3 of a bag at a time, so as not to waste any of the product. It is easier to mix a 1/3 than a half a bag.
Thanks much for your input.
