Methods and compositions are provided that control spread of pathogens and prevent infections. In various embodiments, a liquid impervious substrate having an antimicrobial disposed thereon is provided. In one embodiment, a method of antimicrobially treating a substrate is provided, comprising contacting the substrate with an effective amount of a water stable composition, comprising i) water; ii) a product that is formed by reacting in water: a) an organosilane of the formula R
n
SiX
4−n
where n is an integer of from
0
to
3;
each R is, independently, a nonhydrolyzable organic group; and each X is, independently, a hydrolyzable group, with b) a polyol containing at least three hydroxy groups, wherein all of the hydroxy groups are separated by at least three intervening atoms, wherein the polyol is not hydroxyethyl cellulose, wherein the product is a monomer, oligomer, or a combination thereof, and iii) a wetting agent in an amount of
0.01
% w/w or w/v to
10
% w/w or w/v based on the weight of the total composition for a period of time sufficient to antimicrobially treat the substrate. In various embodiments, the substrate is a face mask or dental product.
