Abstract
A method for applying a contained pattern to prevent solder overrun by applying a composition which can be applied in liquid form to a work surface where it dries, and subsequent soldering on said work surface will be substantially limited to the pattern laid down by the composition so that there is no solder overrun. The composition also has useful fire retardant properties which protects the underlying work surface. Such composition is a mixture of magnesium hydroxide, water and mica in the laminated silica mineral form.
