STONE CARE – SEALANTS

The Layman's definition of 'SEALANT' is “any material placed in a joint opening generally for the purpose of weather proofing a building, so designed to prevent the passage of moisture, air, dust, and heat through all joints and seams in the structure.”

Sealants are of various types –

  • Penetrating sealers (includes silanes, siloxanes, silicates, and siliconate)
  • Acrylics
  • Polyurethanes
  • Epoxies

Panache deals in mainly Penetrating, Acrylics & PU sealants.

Penetrating Sealers - Penetrate and react chemically within the capillaries of the concrete to shield against moisture penetration and deicing chemicals.

These normally are used for Exterior concrete surfaces subject to corrosion and freeze-thaw damage where a natural, matte finish is desired.

It provides invisible protection without changing the surface appearance or leaving sheen.

It provides excellent protection against outdoor exposure conditions. Most products are also breathable, allowing moisture vapor to escape.`

Acrylics sealants- Form a thin protective film on the concrete surface.

These are majorly applied for on both exterior and interior concrete; On projects where easy application and economy is important; To enhance the beauty of colored, stamped or exposed- aggregate concrete; On fast-track projects, since acrylics often dry to the touch within an hour.

These are available in a range of sheen levels. Solvent-based acrylics generally enhance color better than water-based products.

These provide good protection against water and chloride intrusion, but usually wear faster than polyurethanes and epoxies. Solvent-based acrylics generally perform better than water-based products for outdoor use. On indoor surfaces, softer acrylic sealers usually require regular maintenance with several coats of a sacrificial floor finish, or wax, to prevent wear and black heel marks.
