Key features

Deep Penetration Waterproofing: Penetrates 3-10mm deep into substrates to form lasting protection without clogging pores.

High Water Vapor Permeability: Retains breathability by avoiding pore clogging while blocking liquid water ingress.

Strong Alkali Resistance: Specifically designed to withstand alkaline environments in mineral construction materials.

Universal Substrate Compatibility: Suitable for brickwork, concrete, cement fiberboards, mineral plasters, and natural stone.

Versatile Packaging Options: Available in 25L pails, 200L drums, and 1000L IBC totes to suit various project scales.

Efficient Application Process: Recommended dosage of 5L/m2; can be applied via spray or brush after dilution.

Chemical Reaction Mechanism: Reacts with moisture to form Si-O-Si bonds, creating a hydrophobic resin film on the surface.

Product Q&A

Q:What substrates is SiFS-290 suitable for?

It is suitable for absorbent, porous, mineral construction materials such as brickwork, concrete, cement fiberboards, mineral plasters, and natural stone.

Q:How should SiFS-290 be diluted and applied?

Dilute with a ratio around 1:12 using alcohol, hydrocarbons, or petroleum. Apply via spray or brush with a recommended dosage of 5L/m2.

Q:Does the product clog the pores of the substrate?

No, it retains a very high degree of water vapor permeability since neither pores nor capillaries are clogged.

Q:What are the available packaging sizes?

Available in 25L plastic pails (20KG net), 200L drums (180KG net), and 1000L IBC totes (900KG net).

Q:How does the waterproofing mechanism work?

Silanes react with water to form SiOH groups which bond to the substrate, then undergo condensation to form a hydrophobic Si-O-Si resin film.
