PROSOCO Sure Klean Weather Seal Siloxane PD – Water-Based Brick Sealer for Breathable, Long-Lasting Protection

Overview

PROSOCO Sure Klean Weather Seal Siloxane PD is a water-based masonry sealer designed to shield brick, concrete, masonry, stucco, and manufactured stone from moisture while keeping the surface breathable. The formula penetrates deeply, helping to establish a protective barrier that works on both vertical and horizontal masonry surfaces.

One of the standout traits of Siloxane PD is that treated surfaces stay breathable; the sealer does not trap moisture, allowing the masonry to shed water while remaining comfortable to the touch. This balance of protection and porosity is aimed at preserving the natural look of the material rather than creating a heavy, glossy film.

In terms of longevity, the service life is estimated at more than 10 years under typical exterior conditions. For anyone maintaining exterior brick or stone, Siloxane PD presents a practical option that blends durability with a restrained, natural appearance. It is positioned as a solid brick sealer within PROSOCO’s Weather Seal line, suitable for projects where long-term protection and material breathability are priorities.
