Sikadur LT Grout Low Temperature Rapid Grout
Sikadur LT Grout is a low-viscosity modified vinyl ester material that cures at temperatures below 0 °C (32 °F). It is blended with Sikadur Aggregate to provide a grout consistency or repair mortar consistency. It may also be used as an injection resin by combining the A and B components only. ProTrade Warehouse offers this specialized Sika product for low-temperature applications at competitive trade prices.
Where to Use
- Pressure injection of fine cracks (0.18 to 0.56 mm [0.007 to 0.022 in]) in structural concrete, masonry, and other suitable substrates, at low temperatures.
- Gravity feeding of dry cracks in horizontal concrete and masonry to seal against penetration of water and detrimental solutions, at low temperatures.
- With a 4:1 aggregate/resin ratio, a fluid consistency grout is produced for anchor grouting of bolts or deformed bars in concrete or rock.
- With a 5:1 aggregate/resin ratio, a flowable consistency rapid set grout for realigning equipment and machinery, baseplates, soleplates, and columns.
- With a 7.5:1 aggregate/resin ratio, a fast set repair mortar for horizontal surfaces in chemical environments.
Advantages
- Will cure at temperatures below freezing.
- Can be used with different aggregate loads to produce flowable or trowel grade mortars.
- Very chemically resistant to a wide variety of acids, alkalies, and salts.
- May be placed at temperatures as low as -40 °C (-40 °F) and cures as the temperature reaches -20 °C (-4 °F) (for mortars and grouts consistency only).
- Ministry of Transport Québec acceptance.
How to Use
Surface Preparation
To pressure inject or gravity feed cracks, please consult Sika Canada. New concrete should cure a minimum of 28 days. Dry surfaces provide the best results; however, the product will adhere to clean, damp surfaces. Remove all debris from working surfaces. Use suitable means to remove contaminants, heavy laitance, or curing compounds. Special consideration must be given to oil or other foreign material. Pull Tests must always be used to verify adequacy of preparation. Frozen substrates should be heated to remove frost. Holes should be prepared by blowing out with oil-free air.
Mixing
The Component B (hardener) catalyst should be added slowly to the Component A (resin) while mixing with a slow speed mixer (300 rpm). A noticeable colour change will occur, at which time the Sikadur Aggregate should be added slowly while mixing. The material should be mixed for two (2) minutes after all the aggregate has been wet with the resin.
Before placing a 7.5:1 design mix, the surface must be primed by mixing Component A (resin) plus Component B (hardener) and applying at 4 m²/L (163 ft²/US gal.). While still wet, proceed with mixing and placement of the 7.5:1 Sikadur LT Grout Mortar. The 5:1 Sikadur LT Grout design mix is sufficiently “resin rich” to be self-priming when placing. The mixed material should be placed immediately after mixing.
Application
To pressure inject or gravity feed cracks, please consult Sika Canada. The mixed material should be placed immediately after mixing according to the chosen application (injection, gravity feed, grout, or mortar).
Clean Up
Remove uncured product from tools and mixing equipment with Methyl Iso-Butyl Ketone (mi-Bk). DO NOT USE XYLENE. Acetone is a suitable alternate.
Limitations
- Moisture sensitivity; best adhesion on dry surfaces.
- Free water should be blown dry.
- Must not be thinned (resin); solvents will prevent proper cure.
- Minimum age of concrete: 21 to 28 days (depending on conditions).
- Resin minimum in-place curing temperature: -5 °C (23 °F) unless using formulation for -20 °C (-4 °F).
- Maximum neat resin thickness: 3 mm (1/8 in).
- Not for injection of cracks under damp, wet, or hydrostatic pressure/flowing water conditions.
- Contains a flammable monomer; avoid sparks and open flames.

Colour Accuracy Disclaimer: We have taken care to display the most accurate visuals of our products. However, we are not responsible for the colour accuracy of the device you are viewing our swatches on. These variations arise due to different computer monitors and devices (make, model and technology, as well as resolution, contrast and brightness control settings) in much the same way a scan will differ from an original image and a colour photocopy. Furthermore, coatings can exhibit variation in perceived colour depending on gloss level and application method. If you require a very specific colour match, please make your selection via actual swatches and colour boards available at our showroom.
Product Disclaimer: Ensure you read all product, technical and safety data sheets prior to application as liability falls on the applicator. All products must be applied in accordance with manufacturer’s recommended method.
