Water Repellency & Moisture Protection
Water doesn’t need a crack to get in — porosity alone is enough.

Fade-Resistant Color & High Tinting Strength
The specifier's challenge (what problem is solved)
Concrete, masonry and natural stone are constantly attacked by water: freeze-thaw cracking, efflorescence, loss of mechanical strength, fungal growth and permanent aesthetic damage.
How it works
(technical mechanism)
Low-molecular-weight silanes penetrate deep into the substrate and bond chemically with surface hydroxyl groups for lasting internal protection; siloxane polymers stay near the surface, forming a continuous hydrophobic barrier — together giving dual-action protection without blocking vapor transmission.
Main applications
Exposed concrete (beams, columns, walls), architectural precast, brick & block facades, natural or artificial stone, clay or fiber-cement roof tiles, porous/stamped concrete floors, masonry joints, dry-mix mortars, fiber cement
Supporting data or statistics
TECSIFLEX WP1810 and TECSIFLEX WP600 reduce water absorption by more than 85% on cementitious surfaces, natural stone, or brick. They provide high droplet (beading) formation, high resistance to water permeability, and strong water-repellency performance in weathering resistance tests.
Applicable norm/standard
Tested under JC 474-2008 (mortar water-absorption method)
