so how do u make paste out of kalkawasser?
Put about a tablespoon or so of kalk
on a plate or small shallow bowl and keep adding a few drops of water until the paste is the consistency of tooth paste. You don't want it too watery because it will start to slightly dissapate when it hits the water, and you don't want it too dry because it won't "stick" to the rock. Then put a decent sized dab on your finger, stick your hand in the tank and apply where needed.
