GFRC Worktop Premix Kit

Product Information: GFRC Concrete Worktop Premix Kit

The GFRC Concrete Worktop Premix Kit is a complete package that
allows you to create self-compacting concrete mixes for worktops.
It includes all the necessary components, such as the base mix,
superplasticizer, glass fibers, and powdered dye (except for
Off-White). This kit is designed for use with a forced action mixer
or paddle mixer and a suitable mixing vessel.

Equipment Required:

1. Forced Action Mixer or Paddle Mixer
2. Suitably sized mixing vessel (40-50Litre Builders Tub
   recommended)
3. Personal Protective Equipment (PPE) listed below
4. Bucket trowel or similar
5. Clean bucket to weigh out water

Personal Protective Equipment (PPE):

• Gloves or Nitrile Gauntlets
• Eye Protection (goggles or glasses)
• Disposable Overalls
• FFP3 Dust Mask

What Is In The Box?

Each kit contains:

• 1 bag of Base Mix
• 1 pouch of Superplasticizer
• 1 pouch of Glass Fibres
• 1 pouch of Powdered Dye (except for Off-White)

Product Usage Instructions:

1. Empty the contents of the base mix into your mixer or mixing
   vessel. DO NOT ADD THE FIBRES.
2. Weigh out 3.12Kg or 3.12 litres of water.
3. Mix the dry powdered ingredients without adding the water. DO
   THIS ON A SLOW SETTING to reduce dust dispersion. Mix for 2
   minutes.
4. Add approximately 2.5 litres (approx 4/5ths) of the water.
5. Mix for 15 minutes.
6. After 15 minutes of mixing, check the consistency of the mix.
   Signs that the mix is ready are as follows:
   • Air is bubbling up through the mix and bubbles are popping at
     the surface.
   • When a trowel is run through the mix, the mix self-levels and
     closes up within seconds.
7. Add more water in small quantities as necessary until the
   desired consistency is reached.
8. Take a small portion of the mix to pour into the mold for a
   fiber-free facecoat. Spread this evenly over the base of the mold.
   For 0.6 square meters of concrete worktop (1 bag mix), this equates
   to 4.7kg of mix at a thickness of 4mm.
9. Once the face coat is complete, add the Fibres to the remaining
   mix and mix on a slow speed setting for as little time as necessary
   to ensure they are dispersed evenly throughout the mix. This should
   be no more than 2 minutes.
10. Pour the mix carefully over the facecoat already applied and
    proceed according to the Basic Concrete Casting Instructions PDF
    (available to download on our website).
