Sikagard®-730 Concrete Protect Plus

Concrete and masonry water repelling impregnation in cream consistency

Sikagard®-730 Concrete Protect Plus is an aqueous, solvent based, ready-to-use, cream consistency, hydrophobic impregnation based on a mixture of silane and siloxane materials. Sikagard®-730 Concrete Protect Plus is a high performance water repelling impregnation for the protective treatment of masonry, natural stone, concrete building and other mineral structures. Sikagard®-730 Concrete Protect Plus is CE marked as an hydrophobic impregnation complying with EN 1504-2 (Penetration Depth Class I).

  • Easy to apply.
  • Suitable for most types of building materials.
  • CE marked.
  • One coat application.
  • Fast absorption and penetration.
  • Deep penetration depth.
  • Does not change the appearance of the substrate.
  • Good surface water-beading effect.
  • High water penetration resistance.
  • Long term protection.
  • Can be overcoated with organic coatings.
  • Unlike other hydrophobic impregnations, Sikagard®-730 Concrete Protect Plus will repell water under pressure for a period of time (although not suitable for permanent submergence), making it ideal for flood defences.

Usage

Sikagard®-730 Concrete Protect Plus is typically used for the protection of building facades or other structures such as wall build with masonry bricks, and both artificial or natural stone, particularly limestone and sandstone. Sikagard®-730 Concrete Protect Plus is also used to protect low rise fair face concrete building made with a not too dense concrete. As it is functional even under pressure (temporarily), it is ideal for flood defence walls. 
  • Suitable for protection against ingress (Principle 1, method 1.1 of EN 1504-9).
  • Suitable for moisture control (Principle 2, method 2.1 of EN 1504-9).
 
  • Suitable for increasing the resistivity (Principle 8, method 8.1 of EN 1504-9).

Application

Application Information

Ambient Air Temperature

+5 °C minimum / +40 °C maximum

Dew Point

Care shall be taken that application is carried out at a temperature at least 3 °C above dew point conditions.

Substrate Temperature

+5 °C minimum / +40 °C maximum

Substrate Moisture Content

The substrate shall look dry with no damp patches (surface moisture content when measured with Tramex meter shall not exceed 5 to 6 %). Best results are obtained with application performed on dry and very absorbent substrates.

Waiting Time / Overcoating

Can be overcoated with both water and solvent based polymer coatings when required. Always contact the coating system manufacturer for details and confirmation of suitability.
For overcoating with Sikagard®, SikaColor® Emulsion, or any other Sika solvent based coatings, wait at least 5 hours after the application of Sikagard®-730 Concrete Protect Plus.
Consumption

Consumption

Generally ~200 g/m2 in 1 application.
In certain situations a second application may be required. Trial applications are recommended to determine the consumption required as this will be dependent on the nature of the substrate (profile and porosity / permeability, etc.).
Application steps

MIXING

Sikagard®-730 Concrete Protect Plus is supplied ready for use and must not be diluted or mixed as this could break down the emulsion and thixotropic properties of the product.

APPLICATION

For large areas, the best method of application is by airless spray or automatic feed long haired roller in a single operation. For smaller areas, Sikagard®-730 Concrete Protect Plus can also be applied by brush or long-haired / long-piled roller.
Please refer to the Sikagard®-730 Concrete Protect Plus Method Statement, which is available as a separate document, for more specific information and details.
If a second coat is required (in special cases), allow the substrate to dry out thoroughly after the first application.

CLEANING OF TOOLS

Clean all tools and application equipment with water immediately after use. Hardened / cured material can only be removed mechanically.
