ABSTRACT:
A penetrant composition for applying to and penetrating into weather exposed surface materials to prevent moss growth thereon is described. The composition is an aqueous solution containing Na.sub.2 O, SiO.sub.2 and a surfactant for increasing the permeability of the composition into the surface material. A method of protecting weather exposed surface material from moss growth thereon is also described. The method involves the steps of providing a composition including water, Na.sub.2 O, SiO.sub.2 and a surfactant. Approximately 1 gallon of the composition is applied per 100 square feet of surface to be protected. The composition is allowed to dry on and in the surface material at ambient temperatures.
