Compared to classic gypsum, it has a more stable <strong>gypsum setting<\/strong>, making it easier to control colour and <strong>texture<\/strong> is repeatable. Correctly selected <strong>pigment<\/strong> and proper technique allow <strong>achieve a uniform colour<\/strong>but also create <strong>visual effects<\/strong> such as <strong>terrazzo<\/strong> or <strong>marble<\/strong>. In this guide you will find <strong>simple techniques<\/strong>that will help you <strong>dye<\/strong> <strong>gypsum<\/strong> consciously - from the choice of accessories to the finishing touches, with a view to <strong>the creation of decorative<\/strong> details in the home <strong>handicrafts<\/strong>.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p>e-cupstone is <strong>manufacturer of polymeric gypsum<\/strong> - we focus on a coherent ecosystem: <strong><a href=\"https:\/\/ecupstone2.hastastudio.com\/en\/category-product\/gipsy\/\">polymeric gypsum<\/a><\/strong>, <strong><a href=\"https:\/\/ecupstone2.hastastudio.com\/en\/category-product\/pigments\/\">dyes<\/a><\/strong>, <strong><a href=\"https:\/\/ecupstone2.hastastudio.com\/en\/category-product\/silicone-moulds\/\">silicone moulds<\/a><\/strong> i <strong><a href=\"https:\/\/ecupstone2.hastastudio.com\/en\/category-product\/additional-materials\/\">impregnates and varnishes<\/a><\/strong>.<\/p>\n<\/blockquote>\n\n\n\n<h2 class=\"wp-block-heading\">Why does polymer gypsum like colour?<\/h2>\n\n\n\n<p><strong>Polymeric gypsum<\/strong> takes better <strong>pigments for plaster<\/strong> than the classic <strong>gypsum<\/strong>: it is more fluid, vents faster in the mould and, once cured, produces a hard, even <strong>casting<\/strong>. For the creators, this <strong>unlimited possibilities for<\/strong> colours and effects - from subtle pastels to intense saturation. This material <strong>polymer<\/strong> works well with both powdered additives and <strong>liquid pigments<\/strong>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Staining methods: what to choose?<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">1) Colouring \"in the mass\" (purest colour)<\/h3>\n\n\n\n<p>It is a method that <strong>consists of adding to the mass<\/strong> colouring additives during preparation <strong>gypsum mass<\/strong>. First measure <strong>amount of gypsum<\/strong> and water (remember to record <strong>proportions of gypsum<\/strong>), and then:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Pouring gypsum into water<\/strong> - always start the mixture with <em>uploading <strong>gypsum to water<\/strong><\/em>, not the other way around. This way of dosing <strong>gypsum and water<\/strong> facilitates control of viscosity and helps <strong>avoid lumps<\/strong>.<\/li>\n\n\n\n<li><strong>Powdered pigments<\/strong> - easy to dose, allows for intense colour <strong>coloured plaster<\/strong>. Always mix thoroughly so that no <strong>clod<\/strong> has not hit the mould.<\/li>\n\n\n\n<li><strong>Liquid colouring for plaster<\/strong> - quickly blends with the mass and facilitates shade repeatability.<\/li>\n\n\n\n<li><strong>Plaster staining<\/strong> This increases process predictability and reduces contamination at the bench.<\/li>\n<\/ul>\n\n\n\n<p>Use a slow mixer to mix <strong>stirrer<\/strong> in pure <strong>container<\/strong>u; <strong>it is important to maintain adequate<\/strong> habits: work quietly, so as not to aerate the mass and shorten the time <strong>gypsum setting<\/strong>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2) Dyes and pigments: how to choose?<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Pigment<\/strong> mineral or oxide - durable, UV-resistant, ideal for solid colours.<\/li>\n\n\n\n<li><strong>Liquid pigments<\/strong> - comfortable, they give even saturation.<\/li>\n\n\n\n<li><strong>Silk pearlescent dye<\/strong> - A pearlescent effect and delicate play of light. Great for jewellery details and small series.<\/li>\n\n\n\n<li>Special additions: <strong>glitter<\/strong> or small fillers can change the character of a project.<\/li>\n<\/ul>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p>You will find compatible <strong>dyes and varnishes<\/strong> and ready-made kits: <strong><a href=\"https:\/\/ecupstone2.hastastudio.com\/en\/category-product\/pigments\/\">dyes<\/a><\/strong> To <strong>polymeric gypsum<\/strong> and finishes with <strong><a href=\"https:\/\/ecupstone2.hastastudio.com\/en\/category-product\/additional-materials\/\">impregnates and varnishes<\/a><\/strong>.<\/p>\n<\/blockquote>\n\n\n\n<h3 class=\"wp-block-heading\">3) Colour after casting (dry painting)<\/h3>\n\n\n\n<p>After <strong>removing from the mould<\/strong> can be used <strong>acrylic paints<\/strong> - is a good solution for multicoloured details, stencils or rubbings. Such <strong>plaster painting<\/strong> allows for precision and shading, but remember: this is not a substitute for colouring \"in the mass\" if you want a deep and even section colour.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Step by step: preparation and mixing<\/h2>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Weigh water and gypsum<\/strong> - save <strong>proportions of gypsum<\/strong> and stick to the recipe.<\/li>\n\n\n\n<li><strong>Pouring gypsum into water<\/strong> - Spread in a thin stream, allow the powder to soak in.<\/li>\n\n\n\n<li><strong>Adding<\/strong> additives - measure <strong>pigment<\/strong> or <strong>powdered pigments<\/strong>, you can also add to the water <strong>liquid pigments<\/strong>.<\/li>\n\n\n\n<li><strong>Mix<\/strong> quietly 2-3 minutes; wipe the walls if necessary <strong>container<\/strong>a, in order to <strong>avoid lumps<\/strong>.<\/li>\n\n\n\n<li>Check viscosity: with fine details <strong>polymeric gypsum<\/strong> should be a little thinner, with large elements a little thicker.<\/li>\n\n\n\n<li>Pour into the prepared tin.<\/li>\n<\/ol>\n\n\n\n<p>Tip: when you want to conquer <strong>gloss<\/strong> and easy to clean after curing, colour protect <strong>lacquer<\/strong> or <strong>impregnate<\/strong> tailored to <strong>gypsum surfaces<\/strong> - this increases <strong>durability<\/strong> and stain resistance.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Terrazzo, marble and other special effects<\/h2>\n\n\n\n<p><strong>Lastryko<\/strong> (terrazzo) is a hit in <strong>handicrafts<\/strong> and decorations. You will obtain it by two means:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Prepared \"chips\"<\/strong> - prepare in advance thin plates of <strong>polymeric gypsum<\/strong> (different colours) and after curing, cut into <strong>coloured plaster fragments<\/strong>.<\/li>\n\n\n\n<li><strong>Mineral additives<\/strong> - throw in <strong>small pieces of stone<\/strong>granite or glass, as well as <strong>fragments of other material<\/strong>.<\/li>\n<\/ul>\n\n\n\n<p>Such a method <strong>consists of adding to the mass<\/strong> coloured particles, so that <strong>the casting exhibits the characteristic of terrazzo<\/strong> distribution of spots and after grinding <strong>shows a pattern characteristic of terrazzo<\/strong>. If you prefer streaks instead of irregular dots, you can gently <strong>mix<\/strong> two colours just before pouring - a subtle appearance is created <strong>marble<\/strong>. This <strong>unlimited possibilities<\/strong> and extremely wide <strong>unlimited possibilities for<\/strong> personalisation. For a flash, add a touch of <strong>glitter<\/strong>u.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p>Pro tip: light sanding and polishing after pre-curing will bring out the chips and highlight the <strong>decorative<\/strong> nature.<\/p>\n<\/blockquote>\n\n\n\n<h2 class=\"wp-block-heading\">Moulds, casting and safety<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Use only pure forms - <strong><a href=\"https:\/\/ecupstone2.hastastudio.com\/en\/category-product\/silicone-moulds\/\">silicone moulds<\/a><\/strong> are flexible and faithfully reproduce the details, and their resilience protects the <strong>casting<\/strong> when dismantling.<\/li>\n\n\n\n<li>Gently tapping while pouring removes bubbles; with thin walls, control the pace as you <strong>casting thickness<\/strong> influences the setting and drying time.<\/li>\n\n\n\n<li>Always keep <strong>appropriate precautions<\/strong>: <strong>gloves and glasses<\/strong> is standard, especially when working with powders and splashes.<\/li>\n<\/ul>\n\n\n\n<p>O<strong>mould casting<\/strong> draw calmly; with complex shapes, flexibility <strong>silicone mould<\/strong> can realistically <strong>facilitate removal of the casting<\/strong> without loss of detail.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Choice of colour versus type of mix<\/h2>\n\n\n\n<p>Colour and saturation depend on several factors: <strong>type of gypsum<\/strong>, the choice of accessories and the way of working. <strong>Polymeric gypsum<\/strong> (material <strong>polymer<\/strong>) generally gives a stronger colour than regular <strong>gypsum<\/strong>and additionally allows for a smooth <strong>casting<\/strong> with fewer pores. When staining, always test small samples <strong>dry gypsum<\/strong> - You can easily judge the final shade after drying.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Frequently asked questions<\/h2>\n\n\n\n<p><strong>Can it be dyed with paint?<\/strong><br>Yes - in small quantities <strong>paint<\/strong> (e.g. a few drops) can give a pastel look. Remember, however, that excess <strong>paint<\/strong>y may weaken <strong>mix<\/strong> and slow down the process <strong>gypsum setting<\/strong>. Once the details have cured, it is great to paint the <strong>acrylic paints<\/strong>.<\/p>\n\n\n\n<p><strong>How much additive to use?<\/strong><br>Start with 1-3% relative to the weight of the powder and gradually increase. Each <strong>polymeric gypsum<\/strong> reacts slightly differently, so testing allows you to select the target shade and control the <strong>colouring the mass<\/strong>.<\/p>\n\n\n\n<p><strong>Does colour affect processing?<\/strong><br>Usually not, but intense saturation can reduce working time. Quick and clean <strong>processing<\/strong> (sanding, polishing) after pre-curing produces the best effect.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Checklist: from recipe to shine<\/h2>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Plan <strong>casting<\/strong> and prepare a position.<\/li>\n\n\n\n<li>Measure the water and <strong>gypsum<\/strong>; note <strong>proportions of gypsum<\/strong>.<\/li>\n\n\n\n<li>Add <strong>pigment<\/strong> (powdered or <strong>liquid pigments<\/strong>) and only then pour in <strong>gypsum to water<\/strong>.<\/li>\n\n\n\n<li><strong>Mix<\/strong> slowly; avoid aeration.<\/li>\n\n\n\n<li>Pour into the mould; control <strong>casting thickness<\/strong> and curing time.<\/li>\n\n\n\n<li>After <strong>removing from the mould<\/strong> wait until fully dry; only then secure the colour <strong>lacquer<\/strong>em\/impregnate (matt, satin or <strong>gloss<\/strong>).<\/li>\n\n\n\n<li>If you like experimenting, <strong>experiment<\/strong> with crisps and fillers - original series will be created <strong>coloured plaster<\/strong>.<\/li>\n<\/ol>\n\n\n\n<h2 class=\"wp-block-heading\">Inspiration: when which accessory?<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Large, even plane: 'in-mass' colouring + light grinding.<\/li>\n\n\n\n<li>Small figurines and jewellery from the <strong>polymeric gypsum<\/strong>: pearlescent accents (e.g. <strong>silk pearlescent dye<\/strong>).<\/li>\n\n\n\n<li>Pots, trays, holders: <strong>terrazzo effect<\/strong> or <strong>marble<\/strong>; add <strong>small pieces of stone<\/strong> or chips of <strong>gypsum<\/strong>u.<\/li>\n\n\n\n<li>Glossy accents: micro <strong>glitter<\/strong>.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Summary and e-cupstone recommendations<\/h2>\n\n\n\n<p>Colouring <strong>polymeric gypsum<\/strong> gives enormous freedom: from solid colour to sophisticated compositions <strong>terrazzo<\/strong>.
