- For early application of epoxy coatings, on-site testing is recommended. Consult coatings manufacturer for advice.
Application Instructions
Substrate Quality / Pre-treatment
Concrete: Surface must be clean and sound. Remove all deteriorated concrete, dirt, oil, grease, and other bond-inhibiting materials from the area to be repaired. Be sure repair area is not less than 5 mm deep. Preparation work should be done by appropriate mechanical techniques. Obtain an exposed aggregate surface with a minimum surface profile of 3 mm (CSP 6) on clean, sound concrete. To ensure optimum repair results, the effectiveness of decontamination and preparation should be assessed by a pull-off test. Saw cutting of edges is recommended. Saturate surface to be repaired with clean water. Substrate should be saturated surface dry (SSD) prior to application.
Steel reinforcement: Rust, scale, mortar, concrete, dust and other loose and deleterious material which reduces bond or contributes to corrosion shall be removed. Surfaces shall be prepared using abrasive blast cleaning techniques or high pressure water-blasting to achieve a bright metal finish.
Mixing
Mechanically mix in an appropriately sized mortar mixer. Wet down all tools and mixer to be used. Start with 2.1 litres of water added to the mixing vessel. Add 1 bag of SikaQuick-2500 while continuing to mix. Add up to another 0.3 litres of water to achieve desired consistency. Do not over water.
Application
Reinforcement Corrosion Protection / Primer Coating: Where a reinforcement coating is required, apply to the whole exposed circumference of the steel the SikaTop 110 EpoCem or Sika Monotop 910N. The repair mortar must be applied into the coating ‘wet’ on ‘dry’.
Concrete Bonding Primer: Prime the prepared substrate with a scrub coat of SikaQuick-2500 by firmly scraping the scrub coat over the substrate surface to form a thin layer and fill any pores or cavities in the surface. Ensure the whole surface to be repaired is covered by the scrub coat. The repair mortar has to be applied into primer ‘wet’ on ‘wet’.
Repair Mortar: The prepared mortar must be scrubbed into the substrate. Be sure to fill all pores and voids. force materials against the edge of the repair, working towards the centre. After filling the repair, screed of excess. Allow concrete to set to desired stiffness, then finish. If a smoother finish is desired, a magnesium float should be used. Mixing, placing and finishing should not exceed 15 minutes maximum.
To control setting times, cold water should be used in hot weather and hot water used in cold weather.
Curing Treatment
Moist cure should commence immediately after finishing. It is necessary to protect newly applied material from rain. To prevent from freezing, cover with insulating material.
Cleaning of Equipment
Clean all tools and application equipment with water immediately after use. Hardened material can only be mechanically removed.
