Product properties are typically averages, obtained under laboratory conditions. Reasonable variations can be expected on-site due to local factors, including environment, preparation, application, curing and test methods.

HOW TO USE
Surface Preparation
Surfaces must be clean and sound. Surfaces / holes may be dry, damp or wet. Remove dust, laitance, grease, oil, curing compounds, impregnations, waxes, foreign particles and disintegrated materials. Substrate strengths must be verified, with pull-out tests being conducted if strength is unknown.

Application Solid Substrate Installation

Drill the hole to the correct diameter and depth to suit the anchor, using a rotary percussion drill and carbide-tipped bit.
Thoroughly clean the hole in the above sequence. Use an air lance inserted into the back of the hole with the trigger depressed for 2 seconds, blow out all debris. The compressed air must be free from oil and water with a minimum pressure of 6 bar (90 psi). If using a hand pump for holes of 400 mm (16 in) deep or less, pump twice to achieve clean holes. If the hole collects water after the initial cleaning this water must be removed before injecting the resin.
Select an appropriate sized nylon brush, ensuring it is in good condition and suited to the diameter of the drilled hole. Insert the brush to the back of the hole and pull out using a back and forth rotating motion to remove all loose friable material. Repeat the brushing operation. Repeat the steps 2 and 3, finishing with step 2.
Select the appropriate static mixer nozzle for the installation. Also, prepare a good quality dispensing gun, ensuring it is in good working order to extrude the anchoring gel. Wherever practical, use pneumatic dispensers for optimum ease of dispensing.
Unscrew and remove the threaded cap. Pull out the exposed and wire tied plastic film and cut below location of tie.
Screw the static mixer nozzle to the cartridge, secure with the integral nut and insert the assemblage into the dispensing gun. Trigger the dispenser until a uniform colour (no streaking) and consistency are achieved with unmixed material going to waste. If necessary, cut an extension tube to the depth of the hole and push onto the end of the static mixer, and (for rebars 16 mm (5/8 in) diameter or more) fit the correct resin stopper to the other end.
Insert the static mixer tip (resin stopper / extension tube if applicable) to the base of the hole. Begin to extrude the resin, under constant and uniform pressure, and slowly withdraw the static mixer from the hole. Fill the hole to approximately ½ to ¾ full and remove the static mixer completely.
Note: If dispensing is interrupted or altered, re-establish consistency of resin prior to continuing. When using a manual dispenser, release piston pressure by pressing thumb plate at every pause in extrusion.
Insert the threaded bar or reinforcing bar (both should be free from oil or other release agents) to the back of the hole using a back and forth rotating motion ensuring all the threads are thoroughly coated. Adjust to the correct position within the stated working time. Any excess resin should be expelled from the hole evenly around the steel element showing that the hole is full. This excess resin should be removed from around the opening to the hole before it sets.
Leave the anchor undisturbed until the appropriate loading time has been achieved, which will be dependent upon the substrate conditions and ambient temperatures.
Attach the fixture and tighten the nut to the recommended torque, DO NOT OVERTIGHTEN.
Overhead applications: Overhead installation is limited to a maximum embedment depth of 10 x rod diameter. All other directions may be installed up to a maximum effective embedment depth of 12 x rod diameter. The use of wedges is not required for overhead installation. However, when temperatures exceed 21 °C (70 °F), it is advised to use wedges to fix anchors installed overhead until full cure time has elapsed as a precautionary measure

Hollow Substrate Installation

Drill the hole. Then insert the brush using one stroke to clean followed by one blast of oil-free compressed air. Ensure that the drilled hole dimensions are suitable to accommodate a perforated sleeve of the appropriate length and diameter.
Select the appropriate perforated sleeve and insert into the hole.
Insert the static mixer to the back of the perforated sleeve, withdraw 2 - 3 mm (1/16 - 1/8 in) then begin to extrude the resin and slowly withdraw the static mixer from the hole ensuring that there are no air voids as it is withdrawn. Fill the perforated sleeve completely and remove the static mixer completely.
Follow instructions for Solid Substrate Installation 8 – 10, ensuring that gel times and loading times are adhered to before attaching any fixtures and tightening to the recommended torque, where being employed.

Clean Up

Collect with absorbent material. Dispose of in accordance with local disposal regulations. Uncured material can be removed with Sika® Epoxy Cleaner. Cured material can only be removed mechanically.

Limitations

Sika AnchorFix®-2020 is not intended as a cosmetic or decorative material and when anchoring into porous substrates or reconstituted stone, staining or decoloration may occur. Where this is of concern, it is recommended that Sika Canada be consulted for advice and discrete trial applications be undertaken and assessed before proceeding.
Anchoring in solid rock and/or hard natural stone: The strength, composition and porosity of such substrates may greatly vary; it is always recommended to test the product in a sample area to evaluate bond strength.
Store material to above 5 °C (41 °F) and, for ease of application by manual dispensers, precondition to higher temperatures, for example 23 °C (73 °F) when working at low temperatures; the higher the temperature the easier to dispense. Take into consideration reduced working times.
Maximum thickness: 5 mm (6/32 in).
Minimum age of concrete must be 28 days, depending on curing conditions.
Do not thin; solvents will prevent proper cure.
For overhead applications, read carefully the Application section.
Standard and quality of dispenser will impact upon ease of extrusion, especially when using manual equipment; ensure the mechanical advantage is appropriate, pistons are correctly aligned and even pressure is achievable.
Sika AnchorFix®-2020 must only be applied on or into substrates when they are frost-free.
