Builder’s lime is calcium hydroxide, also called hydrated lime. The lime used as garden lime is ground limstone, calcium carbonate.

Hydrated lime is more reactive, quicker to act and less should be used. About 150 to 180 g per metre square is enough.

Be careful using it as it can cause irritation to eyes and skin, and the dust should not be breathed in.

All in all, ground limestone, or garden lime, is a better bet.
