Form HB, Penetration Chart

An important characteristic of architectural finishes is the ability to maintain a uniform appearance on surfaces of varying porosity. This ability, of which gloss and color uniformity are specific aspects, is referred to as penetration resistance. The adjacent sealed/unsealed areas of Leneta Form HB present severe conditions of varying porosity for testing penetration resistance. In addition to qualitative visual observations, photometric measurements on the two areas provide objective numerical values.
