Sculpting

Watch the video above for a quick insight into why Pal Tiya Premium is so popular.

Pal Tiya Premium (PTP) is an easy to use “all-weather sculpting material” that cures to stone-hard without firing or kilns. The working texture is a fine silky clay that is fiber-reinforced for high strength in thin walled applications. It has considerable inherent natural strength.
PTP can be hand laid up without the use of molds or specialized tools.

​Purpose built for large and strong sculptures with very fine surface details. Work may be added to and altered months later.
Pal Tiya Premium is a satisfyingly direct route from your hands to a finished sculpture – with less fuss than any other sculpting medium. 

​And of course it is Weatherproof…

USES
Indoor/outdoor Garden sculptures, Memorials, Fine Art sculpture, bird baths, large scale Public Art pieces, Theme Parks, educational facilities.

ARMATURES
Armatures can be any material that does not absorb the moisture from the PTP during cure. Steel, rebar, chicken wire, plastic, foil, Polystyrene foam, glass, ceramic, etc. 
Every armature requires a final layer of foil on top so the PTP can adhere to the surface.
*Welded steel reinforcement is needed only when approaching large scale work (over 7 feet). 

MIXING
Pal Tiya Premium comes as a dry powder.
It mixes with water to form a silky smooth ‘dough’ for Sculpting with.
By volume: 4 parts PTP to 1 part water. By weight 5 parts PTP to 1 part water
 
Mix together in a bowl, then knead by hand. Add either more water or Premium till it becomes a pliable, dough-like consistency. Continue to knead for 2 minutes.
​For large batches, and electric dough mixer is helpful and the knead time should increase to 5 minutes. 

SAFETY
Use gloves when mixing by hand, as it can dry your hands out. A dust mask is recommended when working around the material as a powder.

COVERAGE
A 3lb bag of dry PTP covers 14×14 inches x 1/4 thick
​A 40 lb bag of dry PTP covers 9 square dt x 1/2″ thick (1 square yard)

WORKING TIME
15 minutes of soft pliable sculpting time (for basic shapes) followed by 2 hours of gradual stiffening (for details).
​It changes as it cures giving you an exciting sculpting experience.

APPLICATION & THICKNESS
Premium is most effective as a strong hollow shell. This saves both time, effort and money. Build a supporting core first (Foil, foam, wire, etc). Over this, apply a thin coat of Premium and begin sculpting.

The final total thickness of a Pal Tiya Premium sculpture is dependent on its size:
1/8 inch (3mm) for really small sculptures such as the owl in our video that will likely be completed in one day.
1/4 inch (5mm) for small sculptures such as the turtle in the same video that will be done over a few days.
1/2 inch (6-12mm) for medium sculptures – between 1-3 ft tall (see below about scratch coat)
 3/4 inch (18mm) for larger sculptures – over 3ft

However,
If your sculpture is between 1-3 feet tall (30-100 cm)  it will require a 1/4 inch (5mm) scratch/furrow coat – see here for video
Anything over 3 feet/ 1 meter,  double the thickness of the scratch coat to 1/2 inch (10mm)

FIBER REDUCTION
For a final detail coat, a fine mesh strainer can be used to sift out up to 50% of the fibers before mixing it with the water. This second coat will accept a lot more surface decoration, fine detail and texture. However, this will make your surface slightly weaker. Do this only where you want extreme detail. The initial base coat will give your sculpture the strength it needs. 

LAMINATION
Subsequent layers may be added on over days, even weeks/months. Proper keying and/or scratch coating is needed. While PTP is soft, inscribe lines or vertical sided furrows into the surface. To apply another layer, slightly dampen the cured area with water and firmly press the fresh PTP into the grooves. In the absence of grooves, they may be cut into the cured surface with a dremel or grinder. 

EMBEDDED MATERIALS
Ceramic, glass, stone, shell and metal can be embedded in the surface. Any material that does not remove moisture from the curing PTP.  Some porous ceramics must be made damp before using 

BEST WORKING TEMPERATURE
The optimal working temperature is 61-70 Degrees F. (16-21 degrees C). Much hotter than that, and the material will cure faster. Using cooler water will slow down the cure time. 

CURING
A proper cure takes several days in the presence of moisture.

Day 1 :wrap your sculpture tightly in plastic so the water in it doesn’t evaporate.

Day 2:  PTP will be the consistency of a soft wood and you may continue to sculpt or carve your work. When wrapping it up on the second day, place wet towels on it and then recover with plastic.

Days 3-28: Keep wrapped in wet towels and plastic.

BEST STRONGEST CURE
80% of your ultimate strength will come in the first 7 days, but if you are making outdoor statuary and want the best possible longevity, keep the wet towels and plastic on for 28 days.

ALTERNATIVELY, on day 1, wrap just in plastic and the next day you can simply submerge fully in cold water. Leave it there for 5 -28 days for the best, strongest, hardest cure.

Planning your PTP sculpture

SHRINKAGE
Our material does contract, but only microscopically. Each layer of Pal Tiya Premium will lock on to the prior layer without significant shrinkage or distortion.

REMOVAL OF SURFACE FIBERS POST CURE
The best way is with a standard propane torch. Pass the flame quickly over the sculpture for a few seconds and they will flash off.
​*Do not overheat your finished sculpture*

SANDING
PTP can be sanded with various grits for a final finish. A dust mask is recommended when sanding.CLEANUP
Clean tools with water
 *This water should not be immediately poured down a sink*.
Allow the particles to settle over night, then pour off the water. The small layer of remaining sediment can then be buried in your garden or removed with your trash.
​Remember, Pal Tiya Premium eventually becomes “stone-hard”.
​Clean tools well or they’ll soon become Neanderthal implements.

FREEZE THAW
We have extensively tested Premium sculptures for sustained wet weathering and freezing conditions (Passing the ASTM C666: at 300 x ‘wet-freeze/thaw-cycles’!) from -4F to +100F. (-20C to 37C) 

PAINTING
Concrete stains and watered down exterior grade house paints work well to tint and color PTP
Oxides can be used integrally up to 5% by weight.

STORAGE
The best option is a sealed plastic container/pail. Do not place a bag of PTP directly on a concrete floor. Concrete floors hold a lot of moisture naturally and this can wick through even the best bag.

NOT RECOMMENDED
Not recommended for fish tanks or aquatic environments, cups and bowls that would be used to contain or serve food or beverages, clothing or kites.
