SikaQuick® Set-45

SikaQuick® Set-45 is a magnesium-phosphate patching and repair mortar.

12 months when properly stored

Store in unopened containers in cool, clean, dry conditions

***Determined using 1 by 1 by 11" (25 mm by 25 mm by 279 mm) bars. The test was run with neat mixes (no aggregate).

**Method discontinues test when 300 cycles or an RDM of 60% is reached.

Scaling resistance to deicing chemicals

A 50 lb (22.6 kg) bag of mixed with the required amount of water produces a volume of approximately 0.39 ft³ (0.011 m³); 60% extension using ½" (13 mm) rounded, sound aggregate produces approximately 0.58 ft³ (0.016 m³).

• Color variations are not indicators of abnormal product performance.
• SikaQuick® Set-45 will not freeze at temperatures above -20° F (-29° C) when appropriate precautions are taken.
• Do not add sand, fine aggregate, or Portland cement.
• Do not use SikaQuick® Set-45 for repairs less than ½" (13 mm) deep. For deep repairs, use SikaQuick® Set-45 formula extended with aggregate, regardless of the temperature. Consult your Sika representative for further instructions.
• Do not use limestone aggregate.
• Do not deviate from the recommended water content printed on the bag.
• Precondition these materials to approximately 70° F (21° C) for 24 hours before using.
• Protect repairs from direct sunlight, wind, and other conditions that could cause rapid drying of material for the first three hours.
• When mixing or placing in a closed area, provide adequate ventilation.
• Do not use it as a precision machinery grout.
• When using in contact with galvanized steel or aluminum, consult your local Sika sales representative.
• Do not mix partial bags.
• 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 not for supervising or providing quality control on the jobsite.

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 ½" (13 mm).
3. Refer to current ICRI Guideline no. 310.2R for surface prep requirements to permit proper bond.
4. Any surface carbonation in the repair area will inhibit chemical bonding. Apply a pH indicator to the prepared surface to test for carbonation. If carbonation is present, abrade the surface to a depth that is not carbonated.

1. SikaQuick® Set-45 must be mixed, placed, and finished within 10 minutes in normal temperatures (71° F [21° C]). Only mix quantities that can be placed in 10 minutes or less.
2. Do not deviate from the following sequence; it is important for reducing mixing time and producing a consistent mix. Use a minimum ½" slow-speed drill and mixing paddle or an appropriately sized forced-action mortar mixer. Do not mix by hand.
3. Pour potable water into mixer. Use a maximum of 4 pts (1.9 L) of water per 50 lb (22.6 kg) bag of SikaQuick® Set-45. Do not deviate from the recommended water content.
4. Add the powder to the water and mix for approximately 1–1½ minutes.
5. Use neat material for repairs from ½–2" (13–51 mm) in depth. For deeper repairs, extend a 50 lb (22.6 kg) bag of SikaQuick® Set-45 by adding up to 30 lbs (13.6 kg) of properly graded, dust-free, hard, rounded aggregate or non-calcareous crushed angular aggregate, not exceeding ½" (13 mm) in accordance with ASTM C 33, #8 (Test aggregate for fizzing with 10% HCl). If the aggregate is damp, reduce the water content accordingly. Special procedures must be followed when angular aggregate is used. Contact your local Sika representative for more information.

1. Immediately place the mixture onto the properly prepared substrate. Work the material firmly into the bottom and sides of the patch to ensure good bond.
2. Level the SikaQuick® Set-45 and screed to the elevation of the existing concrete. Minimal finishing is required.

No curing is required but protect from rain immediately after placing. Liquid-membrane curing compounds or plastic sheeting may be used to protect the early surface from precipitation, but never wet cure.
