MasterProtect H 321
A water based, silane/siloxane clear water repellent for masonry surfaces.
DESCRIPTION:
MasterProtect H 321 is a one component, water based silane/siloxane blend.
MasterProtect H 321 penetrates deep into the substrate where it reacts chemically. The reaction starts immediately as soon as the active ingredients get in contact with the substrate.
The reaction time depends on temperature, humidity and nature of the substrate. The treated surface does bead water shortly after application of MasterProtect H 321.
TYPICAL APPLICATIONS
MasterProtect H 321 is a clear penetrating silane/siloxane based water repellent for use on porous and semi-porous substrates such as clay and calcium silicate brick, honed limy-sandstone and sand-cement render.
