Has Anyone Tried Doing Mosaics On Pal Tiya Premium?

Yes we have had artists push mosaics, shells and glass into the product. Due to the microscopic shrinkage, these hold very well and look amazing!

The shrinkage once cured is less than one-thousandth or 0.087%. Essentially microscopic.

Note: some round sided bead or cabochon tiles can be placed, grouted and finished in the first structural coat. If the tiles have straight sides, these must cure overnight in the adhesive coat before grouting.  

Here's how to use Mosaics with PTP:

Mosaic tiles: Chips of ceramic, glass, stone, shell or other materials
Base: The form/structure on which tiles are placed (pots, tables, frames, sculptural shapes)
Mortar: Adhesive. 1) Ancient, made with slaked lime (lime+water) and sand. 2) Modern, made with Portland cement 
(Common term: Thinset; made of cement, fine sand and a water retaining agent)
Grout: A filler between tiles 

One of the great strengths of Pal Tiya Premium, it can be the base sculptural layer, the adhesive layer and the grouting layer for 3-dimensional sculptural mosaics. Typically these are three different and distinct materials.

Day 1
Build a sculptural form from foil.
Mix and apply a layer of PTP to this foil core and rake it fully. This acts as both your tile adhesive and initial structural coat.
Press your tiles into this layer firmly.
Keep this lightly moist as you place your tiles.
Big tiles may need a good layer applied to their backs to assure full contact 
Try to keep the raked layer below the surface of the tiles
Check that the individual tiles are secured firmly.
Wrap tightly overnight to cure.
Wait at least 24 hours.
Day 2
Unwrap and mist lightly with water.
The tiles should be firmly attached.
Mix and apply a grouting layer to fill in between the tiles.
For very thin spaces, some of the PTP fibers can be sifted out in advance for easier application. 
Be thorough and fill in all the spaces.
Use your fingers, a dry sponge or towel to brush off the surface and level this layer. Repair any holes or voids. Burn off any raised fibers with a quick waft of a torch.
Use a barely damp sponge (almost no water) to lightly wipe the surface till the grouting is nearly level and uniform between the tiles. Do not dilute the grout with too much water
Allow this layer to firm up, 1 hour
Use a dry cloth to polish and remove the film of material from the tiles.
Wrap overnight to cure.

Day 3

Unwrap and perform a final polish of the tile surface with a dry cloth. Burn off any further raised fibers. Allow to strengthen for another day.

Day 4 
Clean the surface and remove the foil if needed. Rasp and sand any edges. Burn off the final fibers
Re-wrap with wet towels for a full cure, 14 days +
After cure
When fully cured, apply stains or colorants
Seal the surface with two layers of concrete sealant and remove any residue off the tiles.
For vases or planters, also coat the inside to prevent the soil from becoming slightly alkaline.
