8. My chalk paint did not adhere to my dresser first painted my bed with layers the 2nd coat is removing the 1st layer on the dresser. Any suggestions?
There could be a couple reasons for that. However, the most common reason is probably because you either didn't wait long enough for the first layer to dry or if it was dried you might have overworked during the second coat (painted for too long) and this could cause the first layer to reactivate and start to come off. So you need to make sure your first layer is dry and not to overwork it when applying the second and third layers.

15. Is it normal to get grittiness when you use Calcium Carbonate chalk paint? Because when I use already made chalk paint it is very smooth.
Yes, when you mix and make your own chalk paint it wouldn't be as smooth and we recommend using a fine grit sandpaper and remove the grittiness.

So if you want a smooth paint then we recommend using the lower amount on the recipe we have on the label.
