red walls and white marks

my sons who love liverpool football club love having there bedroom painted red,but everytime its done,shortly after its covered in white chalk type stuff,my husband says its them with there hands/feet on the walls,but its not always where they put there hands and feets,
is there anyone wheo can tell me if that is why it appears and also is there anything i could add to the paint next time to stop it happening?
thank you so much!!!!!!
