Hi everyone, I've been doing my research here, but still have a few gaps that I would appreciate some help with.
I'm a little confused about the difference between an "acid wash", which my PB is going to do to a dry pool the day after plaster is applied, and an "acid startup", which I'll clearly do immediately after fill.
I was talking to the owner of another plaster company and he said that he doesn't like to do acid washes as they tend to create consistency issues. He prefers to introduce acid after startup, which is clearly an acid startup.
My questions are:
1. Should I tell me PB not to do an acid wash 24 hours after my plaster is applied?
2. Is a bicarbonate startup recommended over a straight acid startup? I've seen this mentioned in some other threads.
3. Do I need to do both? Could I abandon the acid startup if they wash, or vice versa?
4. What is the purpose of an acid wash? Is it to expose aggregate/quartz?
5. What is the purpose of an acid startup? Is it to remove calcium dust?
If I'm correct on questions 4 and 5, then it seems that these tasks are independent of one another and both need to be performed. This is where I'm lost.
I very much appreciate your help and expertise.
