It has improved strength and shrinkage resistance with fine detail reproduction capabilities. It is ideal for casting of thin shell multi-dimensional or baf-relief forms either by “slush” casting or “lay-up”.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWINTERSTONE Casting 2000\u003c\/strong\u003e is a dry white powder ––– a complex multi-component cementitious mixture ––– which when mixed with a nominal amount of water and cast into a mold sets into a stone hard material with faithful reproduction of detail. The hardening process is a result of the internal reactions taking place between the water and the various components. The inclusion of proper reinforcing mesh, either metallic “ hardware cloth ” or alkali resistant fibreglas, as backing to the casting; or chopped strand (e.g. fibreglas, polypropylene) mixed integrally into the back-up mixture produces a structurally sound composite “ shell ” with increased strength characteristics. This surface “ shell ” combined with proper back-up reinforcing rods ( particularly in larger 3 - dimensional sculptures or bas-relief panels ) results in a light and efficient overall structural system and allows considerable freedom in complexity and intricacy of shape.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWINTERSTONE\u003c\/strong\u003e can be integrally pigmented during the mixing stage or can be externally patinated after de-molding. Hardened WINTERSTONE can be refined with abrasives and polished if necessary. Finished and sealed WINTERSTONE is weather stable and may be founded in an outdoor environment. With proper care and maintenance it can be expected to last many years.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWINTERSTONE\u003c\/strong\u003e is easily prepared by mixing water in the ratio of \u003cstrong\u003e18 to 19 parts by weight of water to 100 parts by weight of dry mix\u003c\/strong\u003e. ( This is equivalent to an approximate \u003cstrong\u003evolumetric\u003c\/strong\u003e measure of \u003cstrong\u003e21 to 22 parts of water to 100 parts of \u003cem\u003eloose\u003c\/em\u003e dry mix\u003c\/strong\u003e. The dry mix in the supplied bag is generally compacted due to shipping and handling.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cdiv data-block-type=\"2\" class=\"sqs-block html-block

Mix?\u003c\/h2\u003e\n\u003cp style=\"margin-left: 40px;\"\u003e- When mixed with water Casting Mix is quite liquid and pourable.  It has improved strength and shrinkage resistance with fine detail reproduction capabilities.  It is ideal for casting thin shell sculptures or bas reliefs using the slush casting technique.\u003c\/p\u003e\n\u003ch2\u003eCan I add any fillers to Casting Mix?\u003c\/h2\u003e\n\u003cp style=\"margin-left: 40px;\"\u003e- Other than pigments, no other additional fillers (i.e., metallic powders) are required or recommended.  If metallic powders are desired, they should be used with Winterstone Ultra Mix only.\u003c\/p\u003e\n\u003ch2\u003eWhat is slush casting?\u003c\/h2\u003e\n\u003cp style=\"margin-left: 40px;\"\u003e- Slush casting is when a liquid medium is poured into a mold and \"slushed\" around to provide a thin layer with complete coverage.  Slush casting usually involves multiple pours, leaving time between the pours to allow the medium to set.  \u003c\/p\u003e\n\u003ch2\u003eHow do I reinforce Casting Mix?\u003c\/h2\u003e\n\u003cp style=\"margin-left: 40px;\"\u003e- Once a face layer has been poured, chopped strand can be added to batches which will create the final thickness.\u003c\/p\u003e\n\u003ch2\u003eWhat is the yield of Casting Mix?\u003c\/h2\u003e\n\u003cp style=\"margin-left: 40px;\"\u003e- One pound of dry mix produces approx. 17 cu. in. of hardened end product.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv data-block-type=\"47\" class=\"sqs-block

with a drill works best)\u003c\/li\u003e\n\u003cli\u003eAdd required amount of water - generally 1 part water to 5 parts dry mix.   (Technically 19 parts water to 100 parts dry mix by weight or 22 parts water to 100 parts dry mix by volume.)   Casting Mix is extremely sensitive to very small differences in the quantity of mix water.  The strongest and most durable product results from using as little water as possible\u003c\/li\u003e\n\u003cli\u003eMix with mixer until well mixed (time will vary depending on quantity being mixed).  Be sure to scrape the bottom of the pail to make sure there

molds.  (Polyurethane, silicone, etc.).  Ensure the mold is clean.  Apply appropriate releasing agent to the mold.\u003c\/p\u003e\n\u003cdiv data-block-type=\"2\" class=\"sqs-block html-block

batch of Casting Mix\u003c\/h3\u003e\n\u003cp style=\"margin-left: 40px;\"\u003e- The initial batch should be small enough to use within its open pouring time and yet sufficiient to cover the mold surface to a thickness of 1\/16\" to 1\/8\".   Brush in and\/or pour the Casting Mix into the mold, slushing it around to completely cover .  Pour out any excess.  Allow the face coat to harden for 10-15 minutes.  (NOTE:  Ultra mix can replace Casting Mix for this face coat but an additive will be required to increase fluidity of the Ultra Mix.)\u003c\/p\u003e\n\u003cdiv data-block-type=\"2\"

(up to 1.5% by weight) for additional strength.   Pour the second batch into the cast and slush it around as before.  \u003c\/p\u003e\n\u003cdiv data-block-type=\"2\" class=\"sqs-block html-block

layers\u003c\/h3\u003e\n\u003cp style=\"margin-left: 40px;\"\u003e- The build up can be repeated layer upon layer until the desired thickness is achieved.  The overall thickness need not be greater than 1\/4\" to 3\/8\" for smaller pieces, 1\/2\" to 3\/4\" for life size pieces.  This sample was poured solid.  In this case Urefil micro balloons were added as a filler to reduce material and weight.  Also, when still wet, a threaded rod was added so mounting later is a breeze.\u003c\/p\u003e\n\u003cdiv data-block-type=\"2\" class=\"sqs-block html-block sqs-block-html\"

 Drying\/Demolding\u003c\/h3\u003e\n\u003cp style=\"margin-left: 40px;\"\u003e- Once finished casting cover the entire piece in plastic for even curing.\u003c\/p\u003e\n\u003cp style=\"margin-left: 40px;\"\u003e- The piece may be demolded after 16 to 24 hours, depending on the shape and fragiity of the detail and the flexibility of the mold.  \u003c\/p\u003e\n\u003cp style=\"margin-left: 40px;\"\u003e- If it is demolded before 24 hours, the demolded piece should be re-covered in plastic until the total cure time under plastic is 24 hrs.\u003c\/p\u003e\n\u003cp style=\"margin-left:

type of mold or casting technique used, some minor imperfections may occur.  Repairs should be done before any patinating or sealing work.  \u003c\/p\u003e\n\u003cp style=\"margin-left: 40px;\"\u003e- Seams can be shaved away with a blade or gently sanded away.\u003c\/p\u003e\n\u003cp style=\"margin-left: 40px;\"\u003e- Any air holes or other surface defects can be filled by mixing a small amount of Sculpting or Ultra Mix by hand to a creamy consistency.  Lightly spray the area being repaired and spread the Mix with a fine dry sponge or rubber\/silicone trowel.  Allow this to cure for 24 hours before sanding.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Winterstone","offers":[{"title":"6lb","offer_id":48019448332603,"sku":"842006","price":44.0,"currency_code":"USD","in_stock":true},{"title":"50lb
