SikaEmaco®-1060 EX

(former MEmaco T 1060EX)

Low dust, very rapid-setting cement-based pre-extended concrete repair mortar

SikaEmaco®-1060 EX is a one-component, shrinkage-compensated, very rapid-setting, cement-based pre-extended mortar. It is designed for repairing horizontal concrete surfaces where high early strength gain is required in applications from 38 mm (1.5 in) to full depth.

  • Pre-extension with coarse aggregate at the factory ensures quality and saves contractor labor
  • Low-dusting for added worker comfort and safety
  • Extra low permeability helps minimize chloride intrusion
  • Very rapid setting so that structures can be opened to vehicular traffic in 1 hour
  • Low residual moisture, can be coated in as little as 4 hours
  • Excellent freeze/thaw cycling
  • Shrinkage-compensated, to minimize cracking from drying shrinkage, which reduces stress at the bond line
  • Proprietary cement blend bonds to carbonated and non-carbonated concrete substrates

NOTES ON INSTALLATION

  • Minimum ambient, surface, and material temperature is 4 °C (40 °F)  and rising.
  • Do not mix for longer than 5 minutes.
  • Minimum application thickness is 38 mm (1.5  in).
  • Consult coating supplier for overcoating requirements.
  • Do not mix partial bags.
  • Do not add plasticizers, accelerators, retarders, or other additives.
  • For professional use only; not for sale to or use by the general public.
  • Make certain the most current versions of the product data sheet and SDS are being used.
  • Proper application is the responsibility of the user. Field visits by Sika personnel are for the purpose of making technical recommendations only and are not for supervising or providing quality control on the jobsite.

SURFACE PREPARATION

Concrete

  1. Concrete must be structurally sound and fully cured (28 days).
  2. Saw cut the perimeter of the area being repaired into a square with a minimum depth of 13 mm (1/2 in).
  3. Refer to current ICRI Guideline no. 310.2R for surface prep requirements to permit proper bond.

   

Reinforcing steel

  1. Remove all oxidation and scale from the exposed reinforcing steel in accordance with ICRI Technical Guideline No. 310.1R.
  2. For additional protection from future corrosion, coat the prepared reinforcing steel with SikaTop® Armatech® 100 EpoCem® or Sikagard® P 8100 AP.

MIXING

  1. Precondition material to 21 ± 3 °C (70 ±  5 °F)  before mixing.
  2. Add 1.5 L (0.4 US gal) of potable water to the mixing container for each bag of SikaEmaco®-1060 EX. Add the powder to the water while continuously mixing with a slow-speed drill and paddle, mortar mixer, or other forced action mixer.
  3. Mix for a minimum of 3 minutes until fully homogeneous.

APPLICATION

  1. After removing all standing water, thoroughly scrub a thin layer of bond coat into the saturated surface with a stiff-bristled broom or brush. Do not dilute the bond coat with water. Do not apply more of this bond coat than can be covered with mortar before the bond coat dries. Do not retemper the bond coat.
  2. Immediately place the repair mortar from one side of the prepared area to the other. Work the material firmly into the bottom and sides of the patch to ensure a good bond. Level the SikaEmaco®-1060 EX and screed it to the elevation of the existing concrete. Apply the appropriate finish.
  3. Finish the completed repair, as required, taking care not to overwork the surface.
  4. The recommended application range of SikaEmaco®-1060 EX is from 4 to 29 °C (40 to 85 °F). Follow ACI 305 and ACI 306 for hot or cold weather.

CURING TREATMENT

Cure with an approved curing compound compliant with ASTM C 309 or preferably ASTM C 1315. Alternative curing options include the application of a fine mist of water, wet burlap, or polyethylene sheeting for a minimum of 2 days.

CLEAN UP

Clean tools and equipment with clean water immediately after use. Cured material must be removed mechanically.
