Uses:

To grout bearings, machine foundations, columns joints in precast construction

etc.

To grout cavities, gaps, and voids in concrete

 
Substrate Quality:

Concrete, grout, stone: Surfaces must be sound, clean, free of ice, oils, grease, standing water and any loose or friable particles and any other surface contaminants.

The concrete “pull off” (tensile) strength should be > 1.0 MPa.

Steel, iron: Clean, free of oil or grease, rust and scale etc.

Substrate Preparation:

The substrate should be prepared by suitable mechanical preparation techniques such as high-pressure water jetting, breakers, blast cleaning, scrabbles, etc.

The concrete substrates should be pre-soaked with clean water continuously for 2 - 6 hours to ensure a saturated surface dry condition throughout the operation.

Immediately before pouring remove all excess or standing water from within any formwork.

 
Application Method:

Pour grout immediately after mixing into the prepared openings. Ensure that air displaced by the grout can easily escape; otherwise entrapped air will prevent full contact grouting. Wet porous substrates to the saturated surface dry condition.

When grouting base plates etc., ensure that a continuous and sufficient head of pressure is maintained to keep the grout flowing.

To make optimum use of the products expansion properties, apply the grout as quickly as possible (within max.15 minutes).

 
Mixing Tools:

Mix grout powder mechanically in the correct ratio with water with low speed (max. 500 rpm) electric drill to avoid entraining too much air.

Put around 80 to 90% of required water in the mixing drum, followed by Sika Grout 214 and then add the balance water.

Dependent on the desired consistency and flow properties, the mixing ratio can be adjusted.

Do not mix more grout, which cannot be used within Pot Life.

Don't add extra water

 
Mixing:

Water:Powder (For Flowable)= 0.15:0.16 by weight (4.5:4.8 litre water per 30 kg bag).

 
Curing Treatment:

Keep any visible, exposed grout surfaces as small as possible and protect from
premature drying out by suitable measures (keep moist, cover with wet Hessian
etc.).

• Anhydrite screed / Anhydrite flowable screed: Must be ground and thoroughly cleaned with the industrial vacuum.
• Unknown substrates: Tests are recommended for compatibility and adhesion.

• During laying and until it has fully cured substrate temperature must be at least + 10°C and in the case of underfloor heating < + 20°C.
• For Substrate temperatures the standard construction rules are relevant

Ambient Temperature:

• Room temperature above +10°C. Relative air humidity < 75%.
• For ambient temperatures the standard construction rules are relevant

Substrate Moisture Content:

• Maximum substrate moisture content: 4% CM for cement screed (ca. 6% Tramex / Gravimetric weight percent), 0.5% CM for anhydrite screed, 3 - 12% CM for magnesia flooring (proportion of organic parts).
• Maximum substrate moisture content in case of underfloor heating: 3% CM for cement screed (ca. 4.5% Tramex / Gravimetric weight percent), 0.3% CM for anhydrite screed, 3 - 12% CM for magnesia flooring (proportion of organic parts).

Application Instructions:

• When applying more than one coat of sika rapid DPM, the 2nd coat should be applied 90 degree to the 1st. Ensure that a continuous uniform coat is achieved using a medium pile roller, brush or rubber squeegee. When used as a damp proof membrane the finished surface must provide a continuous defect-free layer with a ‘shiny’ appearance. When using multiple coats, allow each coat to fully dry between applications.
