What is Plastic Good For?
STERILITE is a brand of plastic house hold containers that understands this answer well. Plastic is sterile because it is relatively non porous unlike other building materials such as concrete or wood. Being non porous is an important character trait in order to maintain and clean any surface. Since plastic is 'created' or 'born' as the result of a thermoset chemical reaction (heat setting) it is also naturally born sterile and free from any germs.
A really clever marketing idea called THERMOS lead a company to become the leading maker of coffee containers that are made of THERMOSET resins (plastic). Just like THERMOS coffee containers do not leak water epoxy garage floor coatings do not leak water. This is not to say that breathable epoxy can not be made. Breathable plastic is indeed made when the solvent used in the manufacturing process is water. Just like xylene and mineral spirits are solvents so is water. All water based epoxy is always going to be breathable because the water tears holes in the polymer as it escapes in the curing process. This is why breathable garage floor coatings will naturally stain faster, they are more porous, which is why professional companies typically only use them in special circumstances.
