Ahhh!! the final chapter to complete your mosaic. This should be the most rewarding time yet the scariest, what grout colour do I choose?
One of the easiest ways we decide and works great in our classes is the sprinkle test, we often apply a tiny bit of dry grout powder to our work in small areas, and then compare what pops and what doesn't, this can be easily brushed out once you have made a decision.
A great little picture of grouting info we found online which has come in handy.
How much grout do I need?
How much grout you need depends on three things:
the area of the mosaic = Length x Width
the thickness of the tiles
the gaps between the tiles.
If the tiles well-spaced (all gaps under 3mm), then you should be able to cover the entire mosaic of 450mm x 450mm with 500grams of the grout.
Set your mosaic on a piece of plastic to catch all the wet grout that falls off the side as you spread it.
Always seal your completed mosaic art piece, this will protect your mosaic against moisture.
