Take a small amount of wax on a clean lint free cloth and rub in a circular motion, finishing with the length of the grain.
For chalky paint finishes you can use a brush especially for antiquing and in mouldings or carved areas.
Let the wax dry for around 10-15 mins
Buff off with another lint free soft polishing cloth finishing with the length of the grain.
Handy hint: It is better to use two thin coats rather than one thick coat.
For filling splits add an extra dab of wax onto the end of a soft cloth and push into the split or crack, wipe of excess and allow to dry.
