Mixing :

For Flowable
Water: Powder = 0.13 to 0.14 by weight (3.9 l to 4.2 l water per 30 kg bag).
For Pourable
Water: Powder = 0.12 by weight (3.6 l water per 30 kg bag).

Mixing Time
3-5 minutes minimum

Mixing Tool
Mixing equipment shall be power operated general concrete mixer or paddle mixer for large grout quantity and for small application a hand held heavy duty slow speed drilling machine fitted with mixing paddle shall be used for mixing a maximum of 50 kg of grout at a time.
Put around 80 to 90% of required water in the mixing drum, followed by SikaGrout® VHS and then add the balance water.

SikaGrout® VHS is best mixed in forced action mixer. Powder is gradually added to the pre-measured water and mixed mechanically with a slow speed drill (400 – 500 rpm) attached with a paddle type mixer, until a smooth and even consistency is achieved.

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. DO NOT ADD EXTRA WATER.

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 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).

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.).

Clean all tools and application equipment with water immediately after use. Hardened/cured material can only be mechanically removed.
