Step-by-step instructions"},"content":{"rendered":"<p>Creating casts from polymer gypsum is a fascinating activity that allows many creative projects to be realised - from wall decorations to terrazzo and utility accessories. The key to success, however, is the right technique for preparing the mass. In this article, we will show you, <strong>how to make polymeric gypsum<\/strong>to obtain <strong>uniform<\/strong>, <strong>even casting<\/strong>without bubbles or imperfections.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What is polymer gypsum?<\/h2>\n\n\n\n<p>Polymer gypsum is a modern material used in various DIY projects. Unlike traditional gypsum, its formula has been enriched with polymer additives, which increases the <strong>durability<\/strong>, <strong>plasticity<\/strong> and resistance to mechanical damage. It is ideal for creating detailing, terrazzo pieces or jewellery.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What do you need to prepare the plaster?<\/h2>\n\n\n\n<p>Before you start mixing, prepare the necessary accessories:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>gypsum powder<\/strong> (e.g. <a href=\"https:\/\/ecupstone2.hastastudio.com\/en\/produkt\/polymer-gypsum-handicast-65mpa\/\">HandiCast polymer gypsum<\/a> from e-cupstone.co.uk),<\/li>\n\n\n\n<li><strong>clean water in appropriate proportions<\/strong>,<\/li>\n\n\n\n<li><strong>bowl<\/strong> or mixing container,<\/li>\n\n\n\n<li><strong>stirrer<\/strong> (manual or mechanical),<\/li>\n\n\n\n<li><strong>protective gloves<\/strong>,<\/li>\n\n\n\n<li><strong>silicone or plastic mould<\/strong>,<\/li>\n\n\n\n<li>optional: <a href=\"https:\/\/ecupstone2.hastastudio.com\/en\/category-product\/pigments\/\"><strong>pigments for plaster<\/strong><\/a>, <a href=\"https:\/\/ecupstone2.hastastudio.com\/en\/category-product\/additional-materials\/\"><strong>impregnate<\/strong>, <\/a><strong><a href=\"https:\/\/ecupstone2.hastastudio.com\/en\/category-product\/additional-materials\/\">lacquer<\/a> for surface finishing<\/strong>.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">How do you choose the ratio of water to gypsum?<\/h2>\n\n\n\n<p>One of the most important steps is to choose the right proportions. In the case of polymer gypsum, it is recommended to <strong>pouring powder into water<\/strong>and not the other way around - thus making it easier to achieve <strong>uniform consistency<\/strong> and avoid lumps.<\/p>\n\n\n\n<p>\ud83d\udc49 Example proportions:<br>For 100 g of powder, add approximately&nbsp;<strong>22-25 ml water<\/strong> - The exact amount depends on the effect you want to achieve. It is always a good idea to check the polymer gypsum manufacturer's recommendations available at <a href=\"https:\/\/ecupstone2.hastastudio.com\/en\/\" class=\"\">e-cupstone.co.uk<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How to make polymeric gypsum - step by step<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Step 1: Prepare the mould and work surface<\/h3>\n\n\n\n<p>Ensure that <strong>silicone mould<\/strong> is clean, dry and placed on a stable surface. You can lightly spray it with non-stick spray.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 2: Measure the amount of water and pour in the powder<\/h3>\n\n\n\n<p>Pour a pre-measured amount of water into a bowl. Then pour in <strong>water powder<\/strong>and not the other way round - this will help to reduce the formation of bubbles.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 3: Mix until smooth.<\/h3>\n\n\n\n<p>With the aid of an agitator <strong>mix the ingredients<\/strong> for approx. 1-2 minutes. The mixture should be smooth, without lumps - only then will the casting be perfect. If necessary, you can lightly <strong>tap<\/strong> container to let the air out.<\/p>\n\n\n\n<p>\ud83d\udd0e Tip: If you want very fine detail, it is worthwhile <strong>mix the gypsum thoroughly<\/strong>to avoid any loss of finish.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 4: Pour the mixture into the mould<\/h3>\n\n\n\n<p>Gently <strong>fill the mould<\/strong>Try to spread the mixture evenly over the entire surface. Take your time - precision is key. For large moulds, we recommend pouring in several layers.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 5: Wait for complete drying<\/h3>\n\n\n\n<p>Leave the mould in a dry and well-ventilated place. Depending on the thickness and ambient temperature, drying time can be up to 72 hours.<\/p>\n\n\n\n<p>\u26a0\ufe0f Do not speed up the process with a hair dryer or oven - this can adversely affect the structure of the casting.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 6: Take out and finish the casting<\/h3>\n\n\n\n<p>After <strong>when the castings are completely dry<\/strong>&nbsp;you can <strong>proceed to sanding<\/strong>, <strong>varnishing<\/strong> or impregnation - depending on the effect you want to achieve. <strong>Finishing<\/strong> is the stage that will put the finishing touches to your project.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The most common mistakes when mixing gypsum<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Bad <strong>amount of water<\/strong> - Too much water = brittle casting, too little = difficulty in pouring into the mould.<\/li>\n\n\n\n<li>Inaccurate mixing - uneven texture and air bubbles.<\/li>\n\n\n\n<li>Removing too quickly from the mould - can lead to damage.<\/li>\n\n\n\n<li>Using the wrong type of gypsum for a particular project.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Why choose gypsum from e-cupstone.co.uk?<\/h2>\n\n\n\n<p>As an experienced manufacturer of polymeric gypsum, we offer products with stable parameters, ideal for creating precise <strong>foundries<\/strong> projects.
