Sikagard® H 1100

(former MProtect H 1100)

100% Silane based water repellent for concrete protection

Sikagard® H 1100 is a ready to use, one component, colourless, 100% alkylalkoxysilane based water repellent designed for protecting concrete. It penetrates deeply into the substrate and chemically reacts within the cementitious substrate.

  • Improves the aesthetics by reducing efflorescence, algae growth and dirt build-up.
  • Surface appearance remains unchanged.
  • Penetrates deep into the concrete, penetration depth class II according to EN 1504-2.
  • Prevents water and chloride ion penetration into the concrete and protects it from freeze-thaw effects.
  • Ready for use, no dilution on the site, which means constant quality.
  • Single layer application possible.
  • CE-certified according to EN 1504-2 as hydrophobic impregenation

Usage

Sikagard® H 1100 is a clear penetrating water repellent to protect both vertical and horizontal concrete surfaces exposed to weathering effects and chloride ions. Sikagard® H 1100 can be used on old and new (cured) structures, like:
  • Bridge decks, piers columns and beams.
  • Multi-Storey car parks, building facades and balconies.
  • Chimneys, cooling towers.
  • Concrete pavements and pedestrian ways.
  • Airport runways and taxiways.
  • Exposed concrete surfaces (e.g. building façades).
  • Precast concrete elements.
  • Marine structures and jetties.

Application steps

SUBSTRATE PREPARATION

New cured concrete surfaces should be cleaned of all sand, surface dust / dirt, oil, grease, chemical films / coatings and other contaminants before application. A complete water-jetting, sandblasting or shot blasting may be needed to achieve the desired surface condition. Crack control, caulking, patching and expansion joint sealants must be installed before the application of Sikagard® H 1100 and allow to cure in accordance with the manufacturer’s instructions.

Any type of cementitious material (e.g. concrete, repair mortars) must have completely cured prior to treatment. For instance, allow minimum 28 days for conventional fresh concrete before treating with Sikagard® H 1100.

MIXING

Sikagard® H 1100 is a ready to use product, no mixing required.

 

APPLICATION

Temperature of the surface, the air and the material should be over +1 °C and below +40 °C during application. Do not apply Sikagard® H 1100 when temperatures are expected to fall below +1°C within 24 hours or rain is expected within 4 hours of completed application.

Surfaces to be treated can be slightly damp, but for best results a dry surface is suggested for maximum penetration. Test a small area of concrete surface before starting general application of any clear, penetrating sealer to assure desired results and coverage rates.

Apply to saturation, with a controlled rundown of maximum 20 cm on vertical surfaces. Low pressure, non-atomizing spay application is recommended or poured followed by brooming for even distribution on horizontal surfaces.

When working in an enclosed area, an air respirator should be used during application.

Sikagard® H 1100 only reacts with mineral based substrates. Therefore, it does not react inside the container or application pump. As long as it is kept in its original container or inside a clean sealed pump, it can be used when ever needed during its shelf life. 

CURING TREATMENT

It is recommended that any surface treated with Sikagard® H 1100 be left undisturbed for a minimum of 4 hours in order to allow proper penetration.

Sikagard® H 1100 may leave a temporarily slippery surface for several hours after application. Therefore, vehicle traffic areas should not be reopened until the treated surface is dry.

CLEANING OF TOOLS

Application equipment should immediately be cleaned with any organic solvent after use.
