S-TECH 40SK™ is an impregnating, invisible fully breathable consolidator and silane water repellent. S-TECH 40SK™ is designed to protect softer, more porous building materials in a freeze-thaw or salt water environment and helps to consolidate friable surfaces. Denser, stronger materials may only require a water repellent, but S-TECH 40SK is recommended for very porous types of natural stone, brick, terracotta, paving and grout which are more prone to spalling damage caused by water freezing and dissolved salts. Treated surfaces become easier to clean, maintain and keep looking good for longer.

General Information

Typical applications:

  • Protection of very porous building materials used in the building envelope and horizontal surfaces, including: Cladding, blockwork, brickwork, grout and salt water pool surrounds, paving and patios.
  • S-TECH 40SK™ is suitable for new build and restored masonry surfaces.
  • Recommended for use on very porous building materials which are exposed to salt water or freeze-thaw conditions.

Suitable surfaces:

Suitable for very porous building materials, including sandstone, limestone, low MPA precast concrete, cast stone, more porous brick, Saltillo, terracotta and grout.


  • S-TECH 40SK™ is a specialized impregnator, designed for premium protection of very porous building materials against spalling in a freeze-thaw and / salt water environment.
  • Penetrates deeply and forms full covalent bonds inside the capillaries for maximum, long lasting performance.
  • Superior protection against other problems caused by water and water borne salts, including: efflorescence,   picture framing and damp migration
  • Widely used for sealing sandstone, limestone, travertine, dry-stamped concrete pavers, cast stone and low MPA precast concrete around salt water swimming pools or on vertical surfaces exposed to freeze-thaw conditions.
  • Retains natural surface color and finish
  • Keeps surfaces looking new for longer, makes cleaning easier
  • Fully breathable, allowing water vapor to escape freely, avoiding harmful moisture build-up inside the material
  • Designed for outdoor surfaces on residential and commercial projects.
  • Negligible change to slip resistance when applied according our written instructions and guidelines.
  • A 15 year performance warranty is available – see Warranty section below for details.
  • High resistance to alkaline (high pH) environments. Concrete is highly alkaline / base and can severely shorten the life of other technologies.
  • Able to seal hairline cracks up to 0.3 mm (0.012 in.)
  • Non film forming so it cannot flake or peel and is resistant to UV
  • Dry-Treat only uses silanes which produce alcohol. Dry-Treat sealer do NOT contain methoxy silanes which emit methanol and can cause blindness / death


A 15 year performance warranty is available if product is applied by a level 3 or 4 Accredited Applicator according to our written instructions and guidelines, at the minimum total application rate for the surface material (see table in the Total Application Rates section above).
Surface materials which are in regular contact with salt water, including the splash zone around salt water pools, must be dip sealed prior to installation to apply for a performance warranty. The material must be fully submerged for a minimum of 15 seconds.
Industry professionals can contact their local Dry-Treat representative or email to enquire about Accredited Applicator training and certification.
