what is porous and non porous
Answers
a porous surface is one that has pores. ... Instead of having pores,
non-porous surfaces are smooth and sealed so liquid and air cannot move through it. On a countertop that is porous and not sealed, water will lay flat.
However, on a non-porous or sealed surface, water will bead up.
