Vasari Lime Paint is made from natural limestone and powdered marble, which enables it to take on the same properties of our plasters. It can be brushed, rolled, or sprayed just like conventional paint but is much more versatile. A medium texture can be achieved with a brush, or it can be troweled smooth, left matte or burnished to a medium sheen.

Sugar. Bandage or Bandaid. Use equal amounts of soap and sugar and mash them together in a clean container with a small spoon or clean finger. For a splinter, you'll only need small amounts of each substance, but you may need to make more poultice to cover a large boil or abscess. Just ensure you make enough poultice to cover the affected area.
