## Questions & Answers

**Q: How much do I need for 80kg of premix concrete bags**
A: Hi, you wouldn't usually need an admixture when you have a premixed product as they are very often already added.

**Q: Being a roofer with winter on the way, i need my cement to dry fast.  How much faster is it with this in,. Thanks**
A: Hello, I was very impressed with this product. I certainly speeds up the setting time, depending on temperature, but it also acts as a frost proofer so you can safely work around the chilly temperatures that would normally risk cracking. All I can say is give it a go and i think you will be impressed.

**Q: hello would this product help against frost after the concrete has set ? or just while its setting ? could this also be used in 52.5 cement?**
A: Hi, this is only intended for frost protection during curing.

**Q: I'm thinking of mixing my own cement for the install of timber gate posts.  How much quicker does the accelerator set concrete, is it postcrete quick?**
A: Not as quick as postcrete by any means but it certainly quickens up the setting time but it also acts as a frostproofer too.
