Hi all
I am ordering the vermiculite for the insulation today and have been informed it comes in three grades. Fine 1 mm, medium 3-4 mm and coarse 8 mm. Which grade is best to use? Will the 8 mm be too coarse and not set well with the cement? Could both medium and coarse be used? Any suggestions would be greatly appreciated.
Regards
Dave
