SikaGrout®-214 VN HP : Water = 1 : 0.13-0.15 (parts by weight)
Water content: 13-15 %
Consistency: Water requirement can be from 3.25 to 3.75 litres per 25 kg
bag depending on the required consistency.

At 27 °C / 65 % r.h

Min. gap: 10 mm 

Max. gap: Please contact Sika Technical Serice department 

Min. +10 °C
Max. +40 °C

1 bag yields approx. 13.10 litres of mortar
Approx. 76 bags required for 1 (one) m³ of mortar

Powder should be added to the pre-gauged water to
suit the desired consistency.
Mix mechanically for at least 3 minutes with a low
speed electric drill (max. 500 r.p.m.) with a disc agitator
attached, until a smooth consistency is achieved.
Mixing equipment such as two arms, forced action
basket/pan type mixer can also be used.

Pour mortar after mixing. Ensure that air entrapped into the grout is allowed to escape. When carrying out base plate grouting, ensure sufficient pressure head is maintained to keep mortar flow uninterrupted.
Make sure that necessary form work is firmly in place and watertight. To achieve optimum expansion result, apply mortar as quickly as possible.
Grouting of machine beds
Pre-wet thoroughly, no standing water in bolt holes. If possible, grout anchor first, and the mortar bed in the second operation. Ensure continuous flow of mortar.
Grouting base plate
Prewetting for approx. 24 hours, no standing water.
Maintain constant hydro-static pressure to continuous flow. Use steel rods or chain to make sure that all cavities are filled. Make sure that entrapped air can escape easily.
Grouting of large cavities / large volume
Depending on the volume to be filled and thickness of gap, large aggregates, e.g. 4–8 mm, 8–16 mm or 16–32 mm may be added to the SikaGrout®-214 VN HP at a ratio of between 50-100% by weight of SikaGrout®-214 VN HP powder. Round aggregates are more suitable than crushed ones.
As a rule of thumb, minimum thickness of gap to be grouted shall be 3 times max. grain size diameter of aggregate.
For grouting large section thicker than 60 mm, addition of large aggregate and/or use of cold water will minimize temperature rise generated during early hardening period.
Special anchoring (rock bolt in tunnels). Please consult
Sika for additional information on anchoring and grouting products.

Keep visible, free mortar surface as small as possible and protect it from premature drying out by standard curing practice (keep moist, cover with wet hessian, use of curing compound e.g. Antisol® E).

Clean all tools and equipment with water immediately after use.
Hardened mortar can only be removed mechanically.
