Application:

Concrete  surfaces  should  be  clean,  sound  and  free  from  oil,  grease, laitance  and  loose  particles.

Metal  surfaces  (iron  and  steel)  should  be  free  from  scale,  rust,  oil  and grease.

Absorbent substrates must be saturated thoroughly, but no standing water.

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 head of

pressure 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 (preferably within 15

minutes after mixing)

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 214-11 at a ratio of between 50-100% by weight of SikaGrout 214-11 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  aggre- gate  and/or  use  of  cold  water  will  minimize  temperature  rise  generated during  early  hardening  period.

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.  Hard- ened  mortar  can  only  be  removed  mechanically.

Minimum application temperature is 10 C. At temperature lower than 20 C setting  time  and  strength  gain  will  be  slower.

Normal  curing  practice  should  be  observed  for  at  least  3  days  wherever mortar  is  exposed.

In  case  of  grouting  large  cavities/volume,  SikaGrout  214-11  is  the  most
