Application Fields

VARIPHOB® CC 4140 is especially recommended for the protection of the following alkaline mineral materials or as a primer for paints.

• Cement-based construction materials
• Concrete (non-load bearing manufactured concrete products)
• Reinforced concrete in bridge, road and building construction
• Alkaline mineral substrates
• Lime-sandstone
• Repairmortar

Recommendation for Use

• Impregnation:

  • VARIPHOB® CC 4140 is processed by flooding or saturated application by brush on alkaline surfaces. A double layer "wet-on-wet" application is absolutely recommended to avoid defects.

  • Soilings are to be removed prior to applying the product. The ground must be dry, solid and free from dust and grease.

  • The efficiency and penetration depth of VARIPHOB® CC 4140 is depending on the moisture of the substrate.
  • Water spots or individual moist spots on the concrete surface lead to an uneven impregnation. Water or rain may not get in contact with the emulsion until VARIPHOB® CC 4140 has been completely absorbed by the ground.
  • Freshly treated surfaces must be protected from water impact.
  • When used in combination with insulating materials, the stability of the insulating material to VARIPHOB® CC 4140 must be tested.
  • A direct contact with bitumen must be avoided at any rate.

• Admixture:

  • VARIPHOB® CC 4140 can also used for the mass hydrophobation of alkaline materials.

  • We generally recommend adding 1.0 – 5.0 % VARIPHOB® CC 4140 based on the cement weight to the fresh mortar. The optimal dosage has to be determined in pre-trials.
  • There can be differences in strength and shrinkage compared to a non-hydrophobic system.

Storage & Handling

Shelf Life

12 months

Storage Conditions

• In closed original containers at room temperature (approx. 23°C) the product will be stable for at least 12 months.
• Stir before use.

Stability

• VARIPHOB® CC 4140 is sensitive to frost, after the impact of temperatures below the freezing point irreversible changes can occur.
• The containers must be protected from direct sun radiation and keep from temperatures higher than 30°C.
