Common Mosaic Questions Answered!

Here are the answers to some commonly asked mosaic questions.

Q. Can you mosaic onto wood when making an outside mosaic?

Wood isn't a good choice for an outside mosaic, this is regardless of how you seal it or what adhesive you use. Wood moves with temperature changes and is subject to swelling when it comes into contact with moisture. Sealing will not prevent it from expanding or contracting with temperature changes. 

Keep wood for indoor mosaics only and look into using the following substrates for your mosaic: compressed fibre cement sheeting, marmox, wedi board or a more expensive option Ayrelite (an aluminium honeycomb with a fibreglass skin).

Ayrelite is relatively expensive and not stock by any mosaic suppliers that I know of due to this. It is a building material, one manufacturer that I'm aware of is Ayers Lightweight Panel System. Here is a photo of the some Ayrelite products to give you an idea of what it is.

Q. I am a really bad drawer, how can I come up with a design?

Tracing an image is a good way to make up for a lack of drawing skills. As you are making a mosaic you don't need detail, an outline of the shape is really all that is required. Images from children's drawing books or stained glass patterns are a great source. To learn more about tracing an image, go to our 'How to Mosaic' topic entitled: How To Create Mosaic Designs Simply - Even If You Can't Draw!

To get the image to the size that you are after you can enlarge or reduce it with a photocopier.

Hello Lynda, I have revised the blog post and answered your question in it.

Just to add to the grout topic. 1) Powder should always be added to liquid, rather than the other way round – that way you get the full chemical cure and also don’t have to scrape round the bottom to mix in the powder.
2) It’s important to let cement-based products slake (rest in order to do the chemical reaction called hydration) time to work. After slaking, stir. Different products have different slaking times – see the bag.
3) Don’t add anything after slaking – it disturbs the chemical reaction.
4)I use dry cloths for cleanup. No need to dispose of grouty water that way and no danger of adding too much water to the grout and causing cracking.

where can you find Ayrelite sheets – do they come in large sizes for table tops?
