Check the listing for details. Aqua Cast Water Activated Casting Compound. Condition: New. Listed at 35.24 USD. Aqua Cast is an environmentally friendly fusion of powder and polymer which only needs the addition of water to make beautiful homeware We have fused the acrylic polymer additives into one ground breaking powder. All mechanical properties normally found in a traditional powder and polymer mixture remain the same, giving Aqua Cast excellent cured strength. It couldn't be easier, simply add water, mix and pour. The guide mix ratio is 100 : 35 (100parts powder to 35 parts water, or 2.8 : 1) The user can change the water addition to create a lower or higher viscosity (runnier or thicker) to suit the individual application. Aqua Cast product mass per kit size Aqua Cast 3kg powder (equates to 4.05kg usable material) Aqua Cast 10kg powder (equates to 13.5kg usable material) Aqua Cast 15kg powder (equates to 20.2kg usable material) Aqua Cast 25kg powder (equates to 33.8kg usable material) Easily coloured with water based pigments such as our resi-TINT acrylic inks, acrylic paints or mica powders, e.g. resi-TINT MAX Neon Powder Environmentally friendly Perfect for coasters, ornamental vases, planters, candle holders, soap dishes and detailed figurines Easily pigmented using resi-TINT inks or other water based pigments Ideal for ceramics & textured art pieces Excellent reproduction of detail Can be used to create terrazzo pieces High surface hardness and strength Smooth, impact resistant surface High degree of weather resistance for external applications when sealed FAQ's Is Aqua Cast weatherproof and waterproof? No, it is porous when cured. For external applications and those where the article will hold water it will need to be sealed. We recommend our range of hydroflow Sealers How hard and durable is Aqua Cast? It is extremely tough and durable. Once cured Aqua Cast cures to a hardness of 208 MPa (Brinell) The compressive strength is 55 Mpa when mixed in the guide ratio of 100:35. Will it fade with exposure to sunlight? No this product is 100% UV stable. Is it fire-resistant? Yes, Aqua Cast does not self-ignite nor propagate flame. It is suitable for creating candle holders and fireplaces. Specifications Drying time Demould in 60-90 minutes For maximum cured strength 24-48 hours Mix ratio 100 : 35 (2.8 : 1) e.g. 100g of powder to 35g of water Pot Life 10-15 minutes @ 23°C Shelf life Indefinite when kept dry in storage Mixing Adding colour Use any water based pigment e.g. resi-TINT acrylic inks, acrylic paints or mica powders, e.g.resi-TINT MAX Neon Powder Any solid can be added, sand, mica, quartzite, dried shards of Aqua Cast etc. Mixing the powder The desired viscosity & consistency can be controlled to suit the application. Alterations to the guide powder to water ratio will affect the product performance, particularly in terms of drying time. Measure the desired amount of water, add the corresponding quantity of powder gradually during mixing. For example: 100g powder to 35g/ml water 150g powder to 52g/ml water 200g powder to 70g/ml water 300g powder to 105g/ml water500g powder to 175g/ml water Mix by hand or with an electric mixing blade for 2-4 minutes until uniform and smooth. Add pigments at the mixing stage to obtain the desired colour shade. The mixed solution will rapidly become creamy and lump free, tap the mixing container to help remove trapped air. Application Immediately pour into your mould and allow to settle. Any residual bubbles can be popped by agitating or tapping the mould. Allow to harden for 60-90 minutes before demoulding (temperature and mix ratio dependent). Allow to dry for 24-48 hours to build cured strength.
