Sikagard®-65 WN AE is designed to provide specific chemical resistance to concrete against chlorides and sulphates found in the ground in aggressive environments.

(A : B) = (3 : 1) by weight

Beware of condensation!
The substrate must be at least 3 °C above dew point to reduce the risk of condensation or blooming on the surface of the applied product.

+10 °C min. / +60 °C max.

The substrate can be either dry or matt-damp green concrete and must be cleaned of loose cement particles and all contaminants such as oils, grease, coatings or surface treatments etc..

~60 minutes at +20 °C (Caution! End of pot life is not visually noticeable)

Note: at below 80 % r.h.

Min. 2 hours (25 °C)
Max. 2 days (25 °C)
Note: Apply second coat only after the first coat is tack-free

• The substrate must be sound and of sufficient compressive strength (minimum 25 N/mm²) with a minimum pull off strength of 1.5 N/mm².
• The substrate must be clean, dry and free of all contaminants such as dirt, oil, grease, coatings and surface treatments, etc.
• Concrete substrates must be prepared mechanically to remove cement laitance and achieve an open textured surface.
• Weak concrete must be removed and surface defects such as blow holes and voids must be fully exposed.
• Repairs to the substrate, filling of blowholes / voids and surface levelling must be carried out using appropriate products from the Sikafloor®, Sikadur® and Sikagard® range of materials.
• All dust, loose and friable material must be completely removed from all surfaces before application of the product, preferably by brush or vacuum.

Prior to mixing stir part A mechanically. When all of part B has been added to part A mix continuously for 3 minutes until an uniform mixed has been achieved.
Use a low speed electrical stirrer (max. 600 rpm) to avoid air entrapment. To ensure proper mixing, pour material into a clean container and stir again.

Sikagard®-65 WN AE may be applied either with a brush, roller or airless spray.

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