Making a mosaic trivet: getting started.
Now you know what to expect when making a mosaic trivet, I will show you how to go about it step by step. This part is all about preparing the board which is an irksome but essential stage. This is a beginner’s project – anyone can do it. It’s suitable for children, adults, OAPs and extra terrestrials. It really is so easy there is no real reason not to get started NOW!
This is what you’ll need:
Mosaic trivet: materials.
- A marine plywood board
- Sandpaper (medium grade)
- Stanley knife
- Water soluble white craft glue
- Paint brush
- Clean jam jar
- Wood primer and paint in a colour of your choice.
- White spirit
Direct method: making a mosaic trivet. Preparing the board.
1. Get a piece of marine plywood in the size you require. MDF would do for this project but I’m a great believer in marine plywood as its strong and water resistant so that it can be used for exterior mosaics. I know you are unlikely to be using your trivet in the great outdoors but I always feel that its a good idea to use the best quality materials with mosaics even when not strictly necessary, simply because you are making something that you hope will last and become a bit of a family heirloom. Don’t get wood that’s too thin – it will warp. Mine are 12mm thick. It’s not too expensive either; I bought six pieces of wood 25cm x 25cm, a larger piece of 45cm x 40cm and a few offcuts thrown in for free from my local wood merchant and it cost E13 over here in sunny Greece. Seemed like a bargain to me.
2. Prepare the board. This is important as it protects the wood from the moisture in the grout and helps the tesserae stick to the board. First, use sandpaper to rub the side of the board you will be mosaicking. Not too rough, just a gentle scrub to buff it up and get those ragged edges off. Then, get some water-soluble white craft glue and make a 50:50 mixture with water in a jam jar. Stir it well otherwise you’ll get lumps. Using a normal paint brush (the kind you use for painting the house, 3cm wide or so) treat the same side of the board with a coat of the mixture and leave to dry.

3. When it’s dry, take a Stanley knife and score the board all over in crisscross fashion to help the tesserae stick to the wood.
3. Paint the back of the board with one coat of wood primer and then give it at least one other coat of paint. I hate this part. I just want to get on and make the mosaic and the last thing I want to do is fiddle around with paint but I have discovered to my cost that doing it now saves so much hassle in the long run that I force myself to buckle down. The painted side of the board might get the odd bit of grout on it in the final stages but it easily wipes off whereas woe betide you if you get paint on the tesserae…Now go wash your brush in white spirit ready for next time.

Here are my boards all painted up. In case you are wondering, I stand them on something so that when the paint dries they don’t stick to the table underneath. And in case you are wondering again, I hate the preparation stage so much that I tend to do it in batches so once it’s done, it’s done:
