I have not yet opened the Gold Topping Compound so could return it as the easy flow says its good for all three coats. What's the best combination for DIYers?

Yes you "can" use Gyprock CSR Easy Flow All Purpose for all coats, as an air drying mix it will take longer to dry with thick coats.

My opinion is the setting base coat is a stronger join, if you are throwing mixed compound out then mix a smaller amount at a time.
Save time by having a couple of flexible mixing containers so you dont need to clean them out, just let it dry and knock out any stuff before using the container for the next mix. You should not need a lot of time to set the joints with base coat just ensure its not over filled.

thanks droog. when i used the term "we" in my initial post, i did not mean me. i have been ordered to the green shed to get something easier to use.

maybe you should try basecoat 90 and mix less.

The topping coats are designed to be soft for easy sanding but that also means they are not as strong for use as your base coats so you have an increased chance of cracking in the joints down the track.
With the base coats it is best not to over mix or use dirty water it as it reduces the working time. You can also add a bit of milk into the mix to slow it down

As someone who is a slow but persistent amateur in such matters, here's my two bob's worth. And you may already have these, and they are referred to above:
1. Use BaseCoat with the longest setting time possible. I don't know if Bunnings have 90 minute setting Basecoat, but CSR outlets certainly do;
2. Get yourself a Basecoat mixer - looks a bit like a little outboard motor propeller with a guard on a straight shaft. Plugs into your drill, does a much better mixing job than by hand, and because it's quicker mixing you get a longer working period;
3. Get a silicone rubber mixing bucket or two as ajm writes. Makes for very easy cleanup. Again, I don't know if Bunnings have them, CSR certainly do.

sorry folks. have to say, Easy Flow is fabulous to use. Did a room and a half last night (walls only) after work and the easy flow was, um, easy. Thanks to you all for contributing your views. this forum is a never ending source of knowledge and helpfulness. next question is on cornice....
