HydroGuard®
Pro Solvent MAX
A one-component, solvent-based silane-siloxane treatment that penetrates deeply into mineral and concrete substrates to create a hydrophobic barrier, reducing water absorption while preserving vapour permeability and natural surface appearance.
HydroGuard® Pro Solvent Max is a high-performance, deep-penetrating reactive silane-siloxane designed for impregnating and priming mineral and highly alkaline building substrates. Once applied, it reacts with atmospheric moisture and pore water to form a durable silicone resin network inside the capillaries, dramatically reducing water uptake and protecting surfaces against moisture ingress and wind-driven rain.
Features & Benefits
- Deep-penetrating hydrophobic barrier
- Significantly reduces water absorption and ingress
- Non-film forming — maintains vapour permeability
- Suitable for neutral to highly alkaline substrates
- Strong water-beading effect develops rapidly
- Helps prevent salt blooming and efflorescence
- Strengthens and consolidates mineral substrates
- Improves long-term durability and weather resistance
- Gas permeable — allows moisture vapour to escape
- Effective even on damp substrates
- Tack-free drying for clean application finish
- Provides good adhesion base for recoating
- No visible change to the treated surface appearance
Intended Uses
HydroGuard® Pro Solvent Max is designed for deep-penetrating façade and substrate protection in both new construction and refurbishment environments where breathable water-repellent treatment is required.
Suitable Substrates Include:
- Brickwork and sand-lime brick
- Mineral-based natural and artificial stone
- Aerated concrete and lightweight aggregates
- Mineral plasters and renders
- Cement fibreboards
- Mineral paints and coatings
- All types of concrete, including bridge structures
- Concrete masonry units (CMU)
- Previously painted mineral surfaces
- Clay tiles and porous masonry materials
Typical Applications Include:
- Breathable façade water-repellent treatment
- Protective sealing of concrete and masonry structures
- Reduction of moisture absorption and wind-driven rain ingress
- Efflorescence and salt-bloom prevention
- Primer for breathable façade coatings and paints
- Long-term weatherproofing of mineral building envelopes
