Deep-Penetrating Silane Emulsion | Manta WS101
Manta WS101 is a concentrated penetrating silane emulsion based on a small-molecule silane formulation, used for deep hydrophobic impregnation of concrete bridge barriers, piers, retaining walls, industrial floors and renders. Diluted with water, it penetrates several millimeters into dense concrete rather than forming a surface film, and the treated substrate stays breathable.

Overview
Manta WS101 is a highly concentrated penetrating silane emulsion (active solid content: 43 ~ 58%). Its small-molecule silane formulation is designed to penetrate several millimeters into the dense concrete matrix.
Unlike film-forming coatings that seal the surface, WS101 creates a breathable, vapor-permeable hydrophobic barrier. It allows trapped internal moisture to escape while reducing the ingress of liquid water, which supports the long-term structural integrity of the mineral substrate.
WS101 is supplied as a liquid concentrate that must be diluted with water before application. Manta WS120 is a thixotropic silane cream for vertical and overhead surfaces, and Manta WS100 combines silane with modified polysiloxane for mineral building materials and primers.
Key Features
- Long-term protection that extends the service life of concrete structures
- Substantially reduces capillary water absorption
- Helps to limit damage from de-icing salts and chloride ion penetration
- Mitigates spalling and scaling from repeated freeze-thaw cycles
- Does not alter the original appearance or texture of the structure
- Breathable, vapor-permeable hydrophobic barrier with no surface film
- Helps to limit surface darkening and biological growth (mildew and algae) caused by moisture and acid rain

Application Guidelines & Dilution Logic (CRITICAL)
Step 1: On-Site Dilution (Mandatory for Penetration)
Manta WS101 is supplied as a high-solid concentrate. To achieve the specified deep penetration (several millimeters) into dense mineral substrates, the emulsion must be diluted with clean, potable water prior to application.
- Recommended Ratio: Generally 1:4 to 1:9 (WS101 : Water by weight), depending on substrate porosity and required penetration depth.
- Technical Logic: Dilution significantly lowers the viscosity and slows the initial cross-linking reaction rate. This delay allows the small silane molecules to be drawn much deeper into the capillary network via capillary suction before curing occurs.
Step 2: Surface Preparation
Repair any structural defects in the concrete. Thoroughly clean the surface to remove dirt, laitance, standing water, and oil/grease. Allow the surface to dry for at least 3 days. The substrate must be visibly dry and free of all contaminants prior to impregnation.
Step 3: Application Conditions & Test Patch
- Curing Age: Apply to newly cast concrete after 28 days of curing, and to repaired areas after 14 days.
- Weather: Do not apply if ambient temperatures are below 5°C or above 40°C, or during high winds/rain.
- Test Patch: It is highly recommended to conduct a small test patch (approx. 5 m²) to verify the optimal dilution ratio, exact coverage rate, and penetration efficacy.
Step 4: Application Technique & Dosage
- Method: Apply the diluted solution using low-pressure spraying equipment, a roller, or a brush. When applying by brush or roller, apply at least two coats and keep the surface wet for 2 minutes.
- Dosage: Apply at a coverage rate of 200–250 g/m² of the diluted solution per coat.
- Coats: Two coats are strictly recommended. When spraying, apply continuously until the substrate is fully saturated (flooded). Apply the second coat after 2–4 hours, when the first coat is almost dry.

Frequently Asked Questions
Why must Manta WS101 be diluted before application?
Dilution with clean, potable water, generally at 1:4 to 1:9 by weight depending on substrate porosity and required penetration depth, lowers the viscosity and slows the initial cross-linking reaction. The small silane molecules are then drawn much deeper into the capillary network by capillary suction before curing occurs, which allows penetration of several millimeters into dense substrates.
What coverage rate and coat count does Manta WS101 need?
Two coats are recommended, at 200–250 g/m² of the diluted solution per coat, with the second coat applied after 2–4 hours, when the first is almost dry. When spraying, apply continuously until the substrate is fully saturated. When applying by brush or roller, keep the surface wet for 2 minutes.
How does Manta WS101 differ from film-forming concrete sealers?
It forms no surface film. The treated substrate stays vapor-permeable, so trapped internal moisture can escape while the ingress of liquid water, de-icing salts and chloride ions is reduced, and the original appearance of the concrete is unchanged.
Can I trial Manta WS101 before specifying it?
Yes. Samples are charged. The sample fee includes courier delivery and is deducted from your first formal order. Use Request a Sample and state the quantity and your substrate. The TDS recommends a small test patch to verify the dilution ratio, coverage rate and penetration.
