Sikadur 52 Fast Curing Injection Epoxy:  


Sikadur 52 - Low viscosity epoxy resin




Sikadur 52 is a low viscosity, free flowing and fast curing injection resin and primer/coating based on a 2 component solvent free epoxy resin; ideally suited to a wide range of building and civil engineering applications where highly penetrative material is required. It is available in two grades, Normal and Long Potlife for moderate and high ambient temperatures, respectively.




Sikadur 52 may be used to inject and fill cracks between 0.2 - 5 mm wide in a wide variety of constructions applications. Sikadur 52 does not shrink on curing and forms a rigid, high strength product which exhibits excellent adhesion to most construction materials enabling the restoration of structural adequacy to columns, beams, foundations, decks and water retaining structures. Due to its highly penetrative nature Sikadur 52 is ideally suited for application as a primer beneath Sikadur epoxy mortars or Sikafloor mortars and coatings on dense substrates. Sikadur 52 may also be used to stabilise weak and friable substrates. Special high strength grades can be made to order.




Shrink free

Insensitive to moisture during application, cure or whilst in service

Applicable over wide temperature range

Low viscosity

Excellent adhesion to most building materials even when damp

Proven in service

High tensile and flexural strength

Supplied in factory proportioned units

High early strength

Chemical resistant


Storage and Shelf Life:


Minimum shelf life is approximately 3 years. Store under controlled conditions in original containers (minimum 5C, maximum 35C temperature range).


Instructions for Use


Surface Preparation:


All surfaces to be coated should be mechanically roughened, free from all contaminants (eg. dust, oil, grease, etc.) surface water, laitance, old coatings, corrosion products. Suitable methods of preparation include blast cleaning and scrabbling. For optimum penetration the substrate should be dry.

When Sikadur 52 is used to inject cracks, the cracks must be blown out with oil free, dry compressed air. Cracks in the width range of 0.2 - 5 mm may be successfully injected.




Sikadur 52 is supplied in factory proportioned units comprising the correct quantities of Part A (Resin) and Part B (Hardener). Thoroughly stir both components separately using a slow running drill with a windmill type paddle (max. speed 600 rpm). Decant all of Part B into Part A and mix thoroughly (typically 3 mins). (Not applicable to twin cartridge packs).




When applied as a primer/coating Sikadur 52 should be worked well into the substrate. This is particularly important on damp surfaces. Ensure the attainment of an overall gloss sheen but do not allow the material to puddle. If Sikadur 52 is used as a primer for Sikadur epoxy mortars and Sikafloor mortars and coatings it should be allowed to cure (but no more than 24 hours old) prior to applying the ensuing Sikadur / Sikafloor materials. (Please refer to the relevant Sikadur / Sikafloor Technical Data sheets for further details). When used to fill cracks Sikadur 52 may be gravity fed or pressure injected for horizontal surfaces. Only pressure injection is suitable for vertical or overhead cracks.

To fill horizontal cracks under gravity construct a reservoir above the crack, fill with Sikadur 52 and allow to penetrate. Residual material may be ground off when fully cured. Vertical and overhead cracks should have injection nipples fixed centrally over the crack (between 30 - 50 cm centres) using Sikadur 31 or Sika Anchorfix-1. Seal the surface of the crack with Sikadur 31 or Sika Anchorfix-1. Allow to cure.

Commence injection under pressure from one end of the crack (the lowest nipple on vertical cracks) until the Sikadur 52 exudes from the next nipple, seal off the first and proceed to infect from the second nipple etc. Once the crack is filled and Sikadur 52 fully cured remove the nipples and use a gas torch and paint scraper or grind the surface back to line and level. For further details on crack injection please refer to our Technical Department.




Uncured material may be cleaned from application tools, etc. by using Sika Colma Cleaner (flammable solvent). Cured material can only be removed mechanically.

Important Notes:


If the Part A shows signs of crystallization, before application place the Sikadur-52 cartridge or container in warm water (heated to 60C) for at least one hour.

Do not apply to surfaces with standing water or to water saturated cracks.

For optimum penetration and adhesion substrates should be dry. Maximum moisture content of the substrate 10%.

Do not part mix containers to avoid mix ratio errors.

Do not dilute the product with solvent as this will affect both the cure and in-service performance.

Constant in-service temperatures >70C may affect the performance of the product.


Maximum application thickness 5mm.

Not suitable for injection into cracks less than 0.2mm or greater than 5mm wide. Unless injected under pressure in which case cracks down to 0.15mm are possible.

Maximum permissible substrate temperature 30C ( Normal), 40C (Long Potlife).

If in doubt, consult our Technical Department.

Minimum age of new concrete 3 to 6 weeks, depending on thickness.


Do not apply Sikadur 52 ( Normal) to substrates lower than 5 C and Sikadur 52 (Long Pot life) to substrates lower than 20C.

The temperature at which the Sikadur 52 is stored during the 24 hours before it is mixed will govern its pot life when mixed.

Compressive strengths etc. of epoxy resins must be qualified by the testing method eg. Test Standard or size of specimen under test and the rate at which the test piece is loaded while under test, as these factors will affect the result markedly. Faster loading rates will generally give higher ultimate loads and vice versa. Also, a specimen at lower temperature will show higher strengths and vice versa.


Handling Precautions:


Avoid contact with the skin, eyes and avoid breathing its vapour.

Wear protective gloves when mixing or using.

If poisoning occurs, contact a doctor or Poisons Information Centre.

If swallowed, do NOT induce vomiting. Give a glass of water.

If skin contact occurs, remove contaminated clothing and wash skin thoroughly.

If in eyes, hold eyes open, flood with water for at least 15 minutes and see a doctor.
