0.8 ft³ (23 liters) of mortar / 55 lb. (25 kg) bag

Concrete

• Surfaces must be clean and sound. Remove all deteriorated concrete, dirt, dust, oil, grease, contaminants, laitance and other bond inhibiting materials from the area to be grouted within the form.
• Be sure the grout area is not less than 3/8 inch (10 mm) in depth.
• Preparation work should be done by needle scaling, abrasive blasting, scarifying, high pressure water jetting, scabbling or other appropriate mechanical means. Obtain an exposed aggregate condition with a minimum surface profile of + 1/16 inch (2 mm) [ICRI CSP-4] on clean, sound concrete.
• Prior to placement, mechanically prepared surfaces should be brought to a saturated surface dry (SSD) condition.

Steel

Reinforcing Steel:

• Should be thoroughly prepared by mechanical cleaning to remove all traces of rust and scale.
• For corrosion protection of reinforcing steel located above the waterline use Sika^® Armatec corrosion protection products or Sikadur^®-32 Hi-Mod epoxy (consult applicable current Product Data Sheets).

Corrosion Resistant Metals: 

• As specified, should be mechanically prepared in accordance with industry standards (e.g. stainless steel, galvanized steel, etc.).

FORMING

• When utilizing SikaGrout®-295 US as a pourable grout, construct forms to retain grout without leakage. 
• Forms should be constructed in such a manner to ensure that minimum surface areas are left exposed.
• Forms must be able to rigidly confine the grout during placement and its positive expansion process.
• Forms around baseplates should be constructed high enough to accommodate head of grout.
• Ensure that an adequate volume of mixed grout is available to allow for a continuous and uninterrupted placement.
• Avoid the entrapment of air pockets in the form by installing bleed tubes and/or provide openings or vents that will allow air to escape.
• Forms scheduled for removal after grout has sufficiently cured, should be lined with a suitable bond breaker (e.g. plastic) or form release agent.
• When necessary, construction of a grout headbox is recommended to assist the flow of SikaGrout®-295 US and maintain a continuous placement.

• After assembly and preparation of forms, make sure all mixing, placing and clean up materials are on hand.
• It is recommended to mix mechanically. Do not manually hand stir!
• Initially wet down all contact parts of mixing equipment.
• Pour the appropriate volume of clean water, approximately 73 °F (23 °C) into a suitable mixing container or appropriate mortar mixer. DO NOT OVER WATER!
• Ambient, substrate and material temperatures should be as close as possible to 73 °F (23 °C). If temperatures are higher, use colder water; if temperatures are lower, use warmer water.
• While mixing, slowly add the entire bag's content of powder to the water. Mix only full bags for best results.
• Mix thoroughly with a low speed (400 - 600 rpm) drill using a an appropriate mortar paddle, or in an appropriate mortar mixer to avoid entraining too much air. Approximately midway through procedure, scrape side walls of container to ensure a proper mix. Continue to mix until homogenous, uniformly blended with no lumps.
• Mix until uniform in consistency for a maximum 3 minutes (typical). 

• Place SikaGrout®-295 US immediately after mixing to take advantage of its expanding effect. Within 10 minutes after mixing, place SikaGrout®-295 US into forms in a manner to avoid air entrapment and achieve flow or compaction.
• SikaGrout®-295 US must be confined by forms and baseplates in horizontal and/or vertical direction, leaving a minimally exposed surface.
• For bearing plates, it is necessary to have an entrance hole and an air evacuation hole.
• After the material has sufficiently hardened, trim or shape exposed SikaGrout®-295 US shoulders to desired profile. 
• Refer to ACI 305, the "Guide to Hot Weather Concreting" or ACI 306, the "Guide to Cold Weather Concreting" when there is a need to place this product while either hot or cold temperatures prevail. Thinner placements will be more sensitive to the temperature conditions. 

• Keep visible exposed SikaGrout®-295 US surfaces to a minimum.
• Per ACI recommendations for Portland cement based materials, moist curing is required.
• Wet cure exposed surfaces for a minimum of 3 days at normal temperature conditions (longer for colder temperature conditions) by covering with wet burlap, polyethylene or a a fine mist of water.
• Alternately, apply a suitable, compatible curing compound (e.g. Sikagard-1315 KNS or Sikagard-180 KNS WB) that meets ASTM C309.
• Leave forms in place for a minimum 3 days, depending upon actual temperature conditions.

• Tools should be cleaned with water, immediately after its use while SikaGrout®-295 US is still in an uncured condition.
• Removal of cured SikaGrout®-295 US can only be done by mechanical means.
