Conseal Pure

Silane surface treatment for concrete

Product Description

Conseal Pure is a silane surface treatment for concrete.

This product is restricted to specialist applicators only.

A clear, penetrating, breathable VOC-compliant surface treatment for use on concrete. The unique 100% silane treatment (no solvent) penetrates the substrate and chemically bonds with silica to form a permanent attachment of the water repellent molecule. Creates a deep hydrophobic layer that prevents water and waterborne contaminants from entering the substrate and causing premature deterioration.
By combining low surface tension with a tailored rate of reaction, Conseal Pure is able to move through the moisture boundary layer that lines the pore structure of the substrate. This permits the development of uniform gradient permeation — a consistent level of protection throughout the entire depth of penetration — allowing for longer treatment life, especially on wearing surfaces.

Additional Information


Conseal Pure is a solvent-free, 100% active alkyltrialkoxysilane. Conseal Pure penetrates deeper than traditional silane and siloxane solvent- or water-carried systems. This deeper penetration gives a long-lasting, resistance against water and chloride intrusion. Conseal Pure’s breathable system greatly reduces the amount of water that enters a substrate, thus promoting a “drying out” of the substrate. Reduces the deteriorating effects of water, such as alkali silica reactivity. By incorporating Conseal Pure into your integrated design, you can earn vital Leadership in Energy & Environmental Design (LEED) credits for both new and existing construction projects.

  • Excellent resistance to chloride ion ingress
  • 100% Moisture vapor transmission
  • Mitigation of AAR & ASR deterioration
  • Deep penetration into substrate
  • No change in surface appearance
  • High resistance to alkali attack
  • Long service life
  • Excellent performance on wearing surfaces
  • Quick Dry time after application(1 Hour)
  • Keeps substrates cleaner
Application areas and surface suitability

Conseal Pure is a silane surface treatment for concrete.

For use on cast-in-place, precast, GFRC and high-strength concrete, to protect the reinforcing steel from corrosion due to the effects of water, deicing salts and other waterborne contaminants.
Alleviates deterioration of concrete due to alkali-silica reactivity.
For use on bridge decks where fast drying is needed to minimize lane closures.
For treating heavy-traffic wearing surfaces or areas that receive high salt concentrations (piers, coastal buildings), to provide a high-performance, long-lasting chloride screen.

Expected Wear:
Conseal Pure will provide premium protection for up to 15 years and in many applications, several years longer. However application methods, weather conditions, traffic, harsh cleaning methods and substrate type will affect wear. Avoid use of solvents, strong acids and strong alkalis for extended sealer life.
It is recommended that the sealer be re-applied every 8 – 12 years where harsh conditions exist.

How to use

Read and understand the SDS before use
Always pre-test in an inconspicuous location for sensitivity to chemicals.

Surface Preparation:

  • New installations must be fully cured before application of Conseal Pure (Min 48 hours, however some concrete installations may take up to 28 days to cure. Confirm with the structural engineer).
  • Coverage can vary dramatically depending on the degree of porosity, but is normally 5 to 15 m2 / Lt per coat for open structure, highly porous substrates and 15 to 25 m2 / Lt per coat for dense, less porous substrates.
  • Do not apply in direct sunlight. Temperature must be between 10°C and 28°C.
  • Highly absorbent surfaces may require two coats.
  • Surface must be cleaned to remove all traces of dirt, dust, efflorescence, mould, salt spray, grease, oil, asphalt, paint or any coating. Speak to your Actichem representative for cleaning and preparation solutions.

Ready to use


Concrete must be allowed to cure for a minimum of 28 days. Concrete repair and replacement must be completed prior to application of Conseal Pure. Patching materials, caulking, sealing materials and traffic paint must be fully cured before applying Conseal Pure. All surfaces must be cleaned to remove all traces of dirt, dust, efflorescence, mold, salt, grease, oil, asphalt, laitance, curing compounds, paint, coatings and other foreign materials. Acceptable surface cleaning methods include shot-blasting, sandblasting, water-blasting and using chemical cleaners. Check with your Actichem representative to verify that surface preparation is adequate.
Conseal Pure should be applied using low-pressure (15 to 25 psi) pumping equipment with a wet fan type spray nozzle. Alternate methods include using either a power roller with a 1” nap or a brush. Do not alter or dilute the material. Do not apply to a wet or damp substrate. A test patch should be applied to the substrate by a trained applicator to verify coverage rate and application conditions.
On vertical surfaces, apply the Conseal Pure in a flooding application from the bottom up, so the material runs down 6 to 8 inches below the spray pattern. Coverage rates on horizontal concrete surfaces are between 100 and 350 ft2/gal. Coverage rates on vertical surfaces depend on the type of substrate to be treated. Your Actichem representative can give exact coverage rates for your particular project.

Please refer to the “Penetrating Sealer Application Instructions” for more detailed information.
Precautions: Conseal Pure is a combustible liquid and should be kept away from heat, sparks, open flame and other sources of ignition. Conseal Pure containers should be kept closed when not in use and should be stored at temperatures between 0°F (-18°C) and 120°F (50°C), away from rain and standing water. When working in an enclosed area, an air respirator should be used. Please refer to the material safety data sheet for more detailed information.

  • Conforms to TL/TP OS-A of ZTV SIB 90 standards set by the German Federal Transportation Ministry and to EN 1504-2.
  • Can be used according to principals 1, 2, 5 and 6 of EN 1504-9
