Ok, commissions come in for an external mosaic for a courtyard garden, 1m x 1.5m. I’ll be using marble, limestone and granite tesserae (tiles) approx. 8mm – 10mm in size (regular 10mm depth). My preferred method is to have the pattern, in reverse on paper. Using clear sticky plastic (the type you cover books with) the tesserae are stuck face down. When complete Mapei mosaic mesh is glued to the back. When dry the mosaic is cut into easily handled panels, flipped over and set onto the baseboard, (the mosaic needs to be on a baseboard as it will rest on supports to give clearance underneath for drainage. I may need to insist the mosaic is supported with only channels left for drainage).
I’ll use Mapei Keraquick adhesive and colour enhancer and sealant.
1. I know PVA is no good for this to stick the mesh but what about a waterproof glue?
2. What can I use as a baseboard bearing in mind it will be outside? The base needs to be in one piece and it wil be walked on.
3. They want the mosaic to look ‘old’. One method I use is to use grey adhesive (Mapei Keraquick) as a grout. By using the adhesive when I clean the excess off it takes more out of the gaps between the tesserae thereby making it look worn down. Anyone see any potential problems with this?
Cheers
