SikaQuick®-2500

VERY RAPID-HARDENING REPAIR MORTAR

SikaQuick®-2500 is a 1-component, very rapid-hardening, early-strength gaining, cementitious, patching material for concrete.

  • Very rapid hardening as defined by ASTM C928
  • Can be used with Sikacem® Accelerator for cold conditions, increased early strengths and reduced curing time
 
  • Compatible with Sikafloor®, SikaBond®, and Sika® AcouBond systems
  • Allows application of an epoxy coating within 4 hours
  • Freeze/thaw resistant
  • Easy to use; economical patching and labour saving material
  • Contains no added chlorides
  • Formulated with inert, non-reactive aggregates to eliminate potential Alkali-Aggregate Reactivity (AAR)
  • Open to foot traffic in 45 minutes, to vehicle traffic in 1 hour [+23 °C (73 °F)]
  • Easily applied to clean, sound substrates
  • Not a vapour barrier

Application steps

MIXING

Mechanically mix in an appropriately sized mortar mixer. Start with 2.6 L (5 1/2 pints) of water added to the mixing vessel. Add one (1) bag of SikaQuick®-2500 while continuing to mix. Add up to another 270 mL (1/2 pint) of additional water to achieve desired consistency. For application greater than 25 mm (1 in) in depth, add 11 kg (24 lb) of 10 mm (3/8 in) coarse aggregate. The aggregate must be non-reactive (as per ASTM C1260, C227, and C289), clean, well graded, saturated surface dry, have low absorption, high density and comply with ASTM C33, size number 8 per table 2.
Note: Do not overwater the mix. This may cause excessive bleeding and retardation and will reduce the strength and performance of the material.

APPLICATION

A scrub coat should be applied prior to placement of mortar. Apply a 3 mm (1/8 in) thick scrub coat of SikaQuick®-2500 into the substrate, filling all pores, voids and edges. Onto the fresh scrub coat, force the mortar against the edge of the repair area or onto the resurfacing site, working towards the centre and observing minimum and maximum layer thicknesses. After filling repair, screed off excess. Allow concrete to set to desired stiffness, then finish. If a smoother finish is desired, use a magnesium float. 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 in cold weather.

CURING TREATMENT

Protect newly applied material from rain for at least two (2) hours. To prevent from freezing, cover with insulating material. If necessary, cure using Sika® Florseal® WB-18 & -25, which meets ASTM C309 requirements. Do not moist/wet cure.

CLEAN UP

Clean all tools and equipment immediately after use with water. Once hardened, material can only be removed manually or mechanically.
