Substrates must be properly cured, structurally sound, free of any loose or friable particles, clean, dry and free of any contaminants such as dust, dirt, oil, grease, cement laitance or efflorescence.

• The edges of repair areas should be cut vertically to a min depth of 10 mm.
• The surface roughness should be prepared to minimum CSP 9 acording to ICRI
• Any contamination to be removed from the concrete surface, perform adequate preparation techniques, such as water-jet washing or blast cleaning, in order to remove all traces of any materials that could reduce the product's adhesion to the substrate.
• For applications in hot climates / environments and / or on absorbent substrates, thoroughly pre-dampen the surface immediately prior to the product application, but avoid any ponding / standing water on the surface, which must not be damp to touch and not with a dark-matt / wet surface appearance i.e. it must be saturated surface dry (SSD).
• Reference shall be made to EN 1504-10 for specific requirements.

BONDING AGENT AND STEEL PROTECTION

• Embedded reinforcing steel should be free from scale, rust, oil and grease, and treated with a suitable anticorrosion coating such as SikaTop® Armatec®- 110 EpoCem® or SikaEmaco®-8100 AP.

• The application of a suitable bonding agent, such as Sikadur®-32 Hi-Mod, Sikadur® ADH 1414, or SikaTop® Armatec®-110 EpoCem®, will improve adhesion on large areas or where particularly dense concrete substrates are involved.

Mix the full bag of SikaEmaco® S 486 with the necessary amount of cold water in a clean bucket. Add the SikaEmaco® S 486 powder slowly to the water while mixing continuously for at least 3 to 5 minutes and until a homogeneous consistency is achieved. SikaEmaco® S 486 is best mixed in a forced action mixer. Slow speed double paddle drill can be also used for mixing. Do not mix at faster rate than 500 rpm. The obtained mix results should be very creamy, easily spreadable and thixotropic.

Note: Always start with minimum recommended quantity of water (water/powder ratio), only if required, gradually add water to desired consistency. Do not exceed maximum allowed limit of water per bag weight.
 

Apply SikaEmaco® S 486 on a well prepared saturated substrate or on a tacky bonding agent. The mortar can be applied by spatula, trowel or by spray application. For any thickness more than 50 mm, SikaEmaco® S 486 must be applied in multiple layers. As soon as the mortar has started to set it can be smoothed by wooden or synthetic float. 

Where ambient conditions may lead to rapid surface drying, the use of light water fogging, damp hessian and polythene sheet or application of a suitable  curing compound from Sika® Antisol range is recommended. Do not commence fogging until final set has been reached.

Clean all tools and equipment with water immediately after use. Hardened SikaEmaco® S 486 can only be removed mechanically.
