4G Surface Guard is a long-lasting, water-based impregnation system that provides invisible protection for porous and mineral-based architectural surfaces. Designed for both vertical and horizontal applications, this advanced treatment transforms absorbent substrates into hydrophobic and oleophobic surfaces, repelling both water and oil without altering appearance, texture, or vapor permeability.
Unlike film-forming sealants, 4G Surface Guard penetrates deep into the substrate through gravity and natural absorbency, preserving the surface’s breathability and slip resistance. Once cured, the treatment is undetectable to the eye and requires no stripping for reapplication. With a typical lifespan of up to 10 years, it is ideal for preserving the beauty and functionality of high-traffic and high-value architectural materials.
Applications
-
Masonry, concrete, and natural stone surfaces
-
Porous architectural facades and paving (horizontal or vertical)
-
Uncoated mineral substrates like brick, limestone, sandstone, and travertine
-
Use in conjunction with World’s Best Graffiti Coating for enhanced graffiti resistance
-
Ideal for heritage buildings, monuments, commercial plazas, courtyards, and entryways
Features & Benefits
-
Invisible finish: Preserves natural look, feel, and color of the surface
-
Vapor permeable: Allows moisture to escape, prevents trapped condensation
-
Hydrophobic & oleophobic: Repels water, oil, and common contaminants
-
Easy to clean: Treated surfaces stay cleaner longer and are easier to maintain
-
Eco-safe formulation: Water-based, solvent-free, VOC-free, and odorless
-
No film formation: Does not alter surface friction or slip resistance
-
Flexible application: Use with sprayer, roller, mop, or brush
-
Coverage:
-
160–240 sq ft per gallon (4–6 m² per liter), depending on surface porosity
