Commissioning a Mosaic
Decide on the kind of mosaic that suits
Consider the mosaic’s size and design. Will it be abstract or representational? Will it reflect a particular theme, for example, nature or pattern. The clearer your vision, the better the artist will be able to bring it to life.
Research artists
Look for artists whose previous work you like. MAAI’s website has a list of practicing mosaic artists some of whom work to commission: (Search our Artist Directory). You can also investigate artists’ websites, social media and galleries. Check reviews or get recommendations from people who’ve commissioned mosaics before.
Contact the artist and discuss the detail
Once you’ve selected an artist get in touch to discuss size, design, reference images and materials. It’s also important to talk about your budget and timeline so the artist can give a realistic estimate. Artists can provide sketches, digital mock ups, or even small samples which will give a good idea of the finished mosaic.
Choosing the materials
Mosaics are made up of small pieces called tesserae. These tesserae can be made from number of different materials, the following are the most common.
Glass: Glass comes in many different forms, from stained glass to machine pressed shapes and smalti, a type of handmade glass fabricated specifically for mosaics. Glass for mosaic ranges in price depending on its manufacture and it is generally suitable outdoors.
Porcelain/Tiles: Tiles are made from ceramic or porcelain, it is best to use porcelain for mosaics in outdoor locations as it is dense and less porous than ceramic, so it does not absorb as much water. Ceramic material such as crockery and plates may not be frost proof.
Natural stone: Marble is durable and comes in a large range of types. It is often cut into small squares which are laid down carefully to make up pattern or design. Marble mosaics are durable and usually sealed after construction.
Pebbles: Pebbles are an easy to source natural material that can make beautiful mosaics, they often work well in outdoor paths and architectural setting. They have their own specific means of fabrication and must be set deeply into their base.
Recycled materials: Some artists use broken pottery or other found objects, including plastic, paper, or other surprising elements, the choice is up to the artist! Some materials may not be suitable for outdoor use.
Final agreement
Once the design is finalised, discuss the contract. Ensure the agreement covers the full scope of work, payment terms, timelines, and any other relevant details (e.g., delivery, installation, or shipping). A clear agreement helps set expectations and avoids misunderstandings.
Installation
Depending on the size and nature of the mosaic you may be able to hang or install the mosaic yourself. Otherwise, the artist, or tradesperson can complete the work. Large installations must be well planned from the beginning of the project. Selecting materials and ensuring proper installation and are crucial for both the longevity and aesthetic impact of the mosaic.
Surface Preparation:
It is important to consider the wall, or surface where the mosaic will be positioned, as this will govern the method of mosaic manufacture and installation. As well as being clean, dry, and free of debris the wall must be strong and sound. Take advice from the mosaic artists or other professional person if required. Due to the inclement Irish climate, it is important that exterior grade adhesive, grout and frost proof mosaic materials are used for outdoor work. If the mosaic is going on a board, or substrate, make sure it is an exterior grade, cement board.
Installation:
Outdoor Mosaic is better carried out in the warmer months as any risk of low temperatures or frost will affect the setting of the tile adhesive and grout. Do not install if there is a risk of rain without having a cover or tent available.
Maintenance & Care
• Seal natural stone and mosaics in high-moisture areas.
• Regularly clean the mosaic with mild soap and water. Avoid harsh chemicals or abrasive cleaners that might damage the tiles or grout.
• It is recommended to make an annual check of the mosaic as if there are any areas coming away, they are easily fixed when on a small scale.
Document the process
It’s a good idea to photograph the installation, especially for larger or custom pieces, this can help in future to know the location of any fixture sites (screw holes) on the mosaic that may be covered.
