Although most mosaic sheets are usually around 30cm x 30cm, they vary in size. Always check the exact measurements and coverage of your mosaic sheet. Mosaics, in general, can be applied to any level, firm, clean surface, using the correct adhesives.

It is most important to allow for cuts, breakages and spares so add 10% to your order quantity as a buffer. Mosaics are produced by batch and can vary in shade so ensure you have enough before you begin and that all your mosaics are supplied from the same batch.
Step 1 Before starting, it is important to dry lay a couple of mosaic sheets to check the blend and to ensure as few cuts as possible. You may want to consider our fun mosaic laying ideas here. Dry laying your sheets will also help you to work out the easiest place to start - if possible, start from a corner.
Step 2 Use an adhesive that is recommended for use with your chosen mosaic material and substrate. Your local Beaumont Tiles store can help with this personalised advice.
Step 3 Mix your adhesive following the manufacturer’s recommendations printed on the bag or the product information sheet. Clean the substrate surface so it is free from dust and contaminants.
Step 4 Spread the adhesive with a notched trowel or spreader, no more than one square metre at a time (less if the temperature is warm or if you do not have much experience).
The notches in the adhesive should all run in one direction. When applying mosaics to the wall, we always suggest that the notches run horizontally. Depending on the thickness of the mosaic, a 6mm or 8mm notched trowel is generally best.
Make sure that there is plenty of adhesive on the back of all the mosaic sheets by occasionally lifting one to check.
Step 5 Lay the mosaic tiles making sure that all joints in between pieces and between sheets are even. Sometimes it may be necessary to "ease" the mosaic joint width by cutting a section of the backing mesh to keep joint widths constant.
Larger mosaics can be cut with the scriber breaker as with wall tiles, but most cutting is done by nippers because of the generally smaller size of the mosaic tiles. Mark and remove the mosaic pieces to be cut from the sheet and fit them separately when the main sheet is in place.
Ensure that the tiles are straight by stretching a string from one end of the room to the other and follow the line, or use a straight edge.
Step 6 You can use a grout float to push the mosaics down to give them a nice flat finish. Don’t press too hard so the adhesive comes through all the joints. Don’t forget to clean off excess glue as you go.
Step 7 Clean off any adhesive that may be on the mosaic surface or have seeped through the joints. Make sure your grout joints are kept reasonably clean. This will prevent blotchy grout. A small scrubbing brush is handy for this.
