How I grout a rainbow mosaic house number with sunflower motif!

Hello blogger friends,

I often get asked how I grout my mosaics. I must say from the beginning that no one has ever taught me - this is the just the way I do it, and it is seems to work pretty well, so this is for all you budding mosaicists out there!


Having made the mosaic and all the tiles are thoroughly stuck and are where I want them,  I get the Unibond grout  www.diy.com, plastic jug www.asda.com and spatula www.amazon.co.uk

 
I measure three serving spoons worth of the powder grout (about the right amount for this 20cm x 20cm mosaic), and mix in small amounts of water until I have a buttercream consistency, the same as in the middle of a cake, mixing it together with the spatula. Make sure you don't get a dry lump of grout at the bottom of the jug!

Next, be brave and get spreading! I work the grout firmly into all the spaces between the tiles.

I keep going over the mosaic, spreading the grout on thickly, and then scraping it off with the soft edged spatula, again and again.

The edges are very important in mosaics - especially for this exterior house number - as that is the place where water might get in. I use my index finger to press the grout right into the edge, going round and round the edges until I am sure it is all completely covered. - be careful for sharp edged tiles!

I wipe all the excess grout off, checking once again that there are no gaps - it's amazing how grout sinks and suddenly a hole appears from nowhere!

Before the final wipe, I use a thin and sharp tool to make the holes either side for fixing, before the grout dries.  I paint the sides and back in an exterior paint to finish it off. The mosaic is then ready to go up, and lift your spirits every time you go into your place for years to come 😀
If you have any questions about making mosaics, or a project you are working on, do leave me a comment and I will do my best to answer it for you.

Thanks so much for reading, and look forward to hearing from you.

  2. Hi there - I use the ones from www.hobbycraft.co.uk with the red handles - they are about £15 and lasted me for years!

    1. Hi Melanie - for exterior mosaics I use cement board and for interior mosaics I use marine plywood - I get both at B and Q - good luck! Fx
