Portuguese Inspired Mosaic Tray

This stunning mosaic tray uses our beautiful handmade mosaic tile, printed on-site at The Mosaic Store. Here are the project instructions plus techniques for you to create this mosaic, or if you prefer, you can purchase this mosaic as a kit.

Mosaic Kits are an easy way to get started in mosaics and a great gift idea. They are great for beginners, as they are an easy introduction to the art of mosaic. Our starter kits contain everything you need to start you off on a voyage of discovery for the hidden mosaic artist hiding inside.Click here to purchase your 'Portuguese Inspired Mosaic Tray Kit'.

The tiles are printed high temperatures to create stunning, colourful and intricate designs. These tiles are suitable for indoor use only as they will fade in direct sunlight.

1. Sealing the MDF Tray

This indoor project is not suitable for areas where it will be exposed to moisture or water, as it is not waterproof. As wood is porous, the base needs to be sealed before tiling. A mixture of PVA adhesive & water can be used as the sealer in a ratio of 1 part adhesive to 4 parts water, apply two coats allowing each coat to dry thoroughly (30 minutes to 1 hour). Coat the area where you will be tiling by using a paintbrush.


2. Tiling

The adhesive can be applied either directly to the mirror base or painted individually onto the tiles' back. By far the quickest method is to paint the adhesive onto the mirror base. When using this method, apply to small sections at a time to avoid the adhesive drying out. When the tiles have been laid, allow the adhesive to cure for 24 hours before applying the grout. Run your hand over the tiles to ensure they are all firmly adhered before grouting. If any are loose, remove them and re-adhere.

We have included some crystal 1 & 2cm tiles in this design, which can be used as filler tiles so that no cutting is required.


4. Grouting

This mosaic can be grouted, as usual, no special techniques are required. If you need help with grouting click here to get detailed instructions. To protect the tray run some masking tape around the exposed areas of the tray.


5. Paint

Paint the tray with acrylic paint and seal if desired.


This project is suitable for indoor use only and not in direct sunlight.
