To obtain a crackled look, there are three steps and three layers involved. Achieve a time-worn cracked and peeling paint effect. Cracking was originally used to make the paint look old. However, now it is also used as an effect in its own right.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-size: 14px;\"\u003eAlso, known as craquelure and crackling paint.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-size: 14px;\"\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-size: 14px;\"\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-size: 14px;\"\u003eHow to Use\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-size: 14px;\"\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-size: 14px;\"\u003e1.

This first coat should be a water-based paint such as Derivan Student or, for larger areas, Derivan Chalkboard paint will give the best results. Leave this coat to dry before going to step 2. It is possible to omit this coat. If the desired effect is to show the surface as cracks, the Cracking Medium can be applied directly to any surface that acrylic paints will normally adhere to. For example, if cracking on a wood surface and the desired effect is to have the paint cracking to reveal the woodgrain underneath, skip the first coat and start at step 2 ensuring the surface is clean and free of oil, grease and dust.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-size: 14px;\"\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-size: 14px;\"\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-size: 14px;\"\u003e2 .Apply the Sandwich Coat of Cracking Medium  \u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-size: 14px;\"\u003eOnce the first coat is dry, apply  Derivan Cracking Medium (water-based) . You can use a brush, sponge applicator or roller (either a sponge or short nap roller). Apply the Cracking Medium so that it is as thick as possible but not so thick that it runs when the surface is held vertically. The Cracking Medium is designed to be a high-build coat; therefore, it is very viscous (thick). Do not be overly concerned with obtaining an even flat surface as the Cracking Medium has a built-in flow agent which will allow it to level out as it dries.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-size: 14px;\"\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-size: 14px;\"\u003eIt is possible to thin the Cracking Medium down with water so that it may be sprayed through a spray gun for larger areas. The amount of water used should not exceed 25%. Also keep in mind that the medium must be at least 1-2mm thick to work. Always do a test with the equipment to be used and the dilution rates before embarking on a large project.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-size: 14px;\"\u003eUse approved respiratory equipment if using a spray gun, and do not inhale the Cracking Medium.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-size: 14px;\"\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-size: 14px;\"\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-size: 14px;\"\u003e3.

The top coat must be applied within 12 hours of Cracking Medium drying. The paint used MUST be Derivan Chalk Board Paint or Derivan Student Paint as the Cracking Medium has been especially formulated to work with this paint. The special formulation, unlike some other brands, allows for different types of cracks to be achieved and repeated with consistency. The Matisse Flow or Structure ranges will not always work as a topcoat with the Cracking Medium unless they are mixed with MM5 Matt Medium (this is discussed further in Cracking Metallic and Tube Colours).\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-size: 14px;\"\u003eWhen applying the topcoat, it is important not to re-work areas that have already been covered as re-working an area can lift the cracking coat and stop the process (see below for more details).\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-size: 14px;\"\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-size: 14px;\"\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-size: 14px;\"\u003e* As with any technique, if you've never tried this before it is advisable to practice on some cardboard or scrap material first.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-size: 14px;\"\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-size: 14px;\"\u003e* Derivan Cracking Medium has been made to crack with Derivan Chalkboard Paint and Derivan Student Paint.  Other brands of paint may work with this medium; however, we cannot guarantee performance.\u003c\/span\u003e\u003c\/div\u003e","brand":"デリバン｜DERIVAN","offers":[{"title":"Cracking Medium　250ml","offer_id":42941675733177,"sku":"","price":2400.0,"currency_code":"JPY","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0580\/5926\/0089\/files\/1c896706879d98ff3cfad5a682f1f8de.jpg?v=1748164606","url":"https:\/\/pigiment.live\/en\/products\/3993","provider":"pigiment.live","version":"1.0","type":"link"}
