How to determine how much pigment you need for your mix?

These grouts are extremely concentrated.

  1. Decide how much end-product you require.  We recommend adding a small amount for colour sampling.
    If you want to make up more product of the same colour for your project, it is advisable to mix all the dry product up at one time, to ensure consistency across the project.
  2. Download the FREE Mixing Calculator here
  3. select the colour you are using, and the amount of end-product you require.
  4. Decreasing the amount of pigment will lighten the colour.
  5. If you are mixing multiple colours together, take note of the max load for each, and adjust accordingly.  DO NOT exceed 10%
  6. Mix the pigment into the DRY product – Blend in well.
  7. Take a small amount of the dry, pigmented mix, and add water to assess the colour.

 

 

 

 

I am currently shipping orders on Tuesdays, Wednesday and Fridays.

I operate this business without assistance.  Whilst I DO endeavour to ship as soon as I possibly can, I cannot guarantee to ship out the same day as the order is received.

1-10 Silverback mini glass sheets will fit into a STANDARD SMALL post box.
1-5 Hobby Squares will fit into a SMALL glass box.
Larger orders will require one or more LARGE glass boxes.  Express postage on these parcels is dependant on your postcode. Please email me for a quote if required.

Postage Unders & Overs:

Some errors may occur in shipping calculations, due to the complexities of combining products in one order.  If you have overpaid shipping I will refund, or issue a credit. If you have underpaid, I will invoice for the difference.  If you feel the postage charge is incorrect – please contact me by phone (most immediate) or email.

No refunds will be given for glass sheets damaged in transit.
I package carefully. However, damage may occur during transit. Product is shipped entirely at your own risk. 

International Shipping:

  • – You can now request a Shipping Quote. Please allow a few days to get a response (due to time differences) as these are prepared manually at the end of the business day.

  • – Apologies – I do NOT ship glass internationally. 
  • – Grouts ship to Australia and New Zealand only.

Free Postage (Australia only) on orders above $250 will NOT apply:

  • – If more than one parcel is required.  I will apply Free Shipping to the most expensive (shipping-wise) parcel.  I will bill you for shipping on other parcel(s) in the order.
  • – If a Seniors/Pension Discount code is used.  Please consider carefully which option presents the best value to you.

Your understanding is appreciated.

What you will need

  • Scale to measure in grams
  • Metal measuring spoons
  • Large container for mixing
  • Small container for testing colour (silicone)
  • Metal spatula
  • Mosaic baggies are handy to pipe grout or adhesive onto your piece – available here
  • Dropper or syringe for water

Mixing suggestions

  • Shake powdered colorant and cement base in a plastic bag until very well mixed.
  • Scoop out a small amount into a small silicone cup, add drops of water and mix to determine colour. (Remember it will always dry lighter)
  • If you are satisfied, then transfer the amount you need from the baggie into a mixing bowl and add water slowly until it is peanut butter consistency.

Colour mixing

MIX YOUR DRY CEMENT-BASED PRODUCTS AND COLORANT TOGETHER FIRST BEFORE ADDING WATER

When mixing colorants together to create new colour combinations, mix the colorants dry before adding to your concrete base and liquid.
I recommend you create a small sample board to ensure you get the colour you want.

NOTE: The best colour is achieved by using a white grout or cement-based adhesive. Merlin Mosaica sells white grout , white Cement-based adhesive and Bright White Pourable Cement.

Safety and clean up

  • Particulate (N95) mask is recommended.
  • Avoid contact with skin and clothes.
  • Wash up with water.
