Adding small amounts of OPEN Thinner replenishes the volatile components, allowing the artist to maintain a long working time and to slow the paint from drying on the palette. It can be difficult to accurately gauge the evaporation rate of volatile ingredients during painting, so add sparingly.\u003c\/p\u003e\u003ch6\u003eThinning OPEN Acrylics\u003c\/h6\u003e\u003cp\u003eOPEN Thinner can be used to lower the viscosity of OPEN Acrylics while preserving maximum working time. Water can also be used for this purpose, and will actually reduce the viscosity of the paint even faster, although it will not preserve the extended open time.\u003c\/p\u003e\u003cp\u003eUse with moderation.

To reopen films before they have fully \"locked down\"i, apply OPEN Thinner directly to the paint film, brushing back and forth until the paint has been reconstituted.

However, depending on the environmental conditions, some thickening of OPEN Acrylics can occur in the course of painting. Some artists have used this natural thickening of the paints as a method of creating a different working consistency without adding a medium.\u003c\/p\u003e\u003cp\u003eWhen using non-absorbent palettes, the following guidelines will help maintain the working time and blendability of OPEN Acrylics:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eMist with OPEN Thinner every 1-4 hours to avoid skinning of paint films.\u003c\/li\u003e\n\u003cli\u003eAlternatively, mist with water every 15-30 minutes.\u003c\/li\u003e\n\u003cli\u003eThin paint mixtures can also be reopened for 8-12 hrs. by applying any of the OPEN products and brushing back and forth until reactivated.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eLeft unattended, and under typical ambient conditions, a dollop of paint roughly the size of a small marble could exhibit noticeable surface thickening within 2-4 hrs. However, if misting with OPEN Thinner, similarly sized dollops were still usable after 24 hrs. , with only slight skinning due to a 12 hour period of drying overnight.\u003c\/p\u003e\u003ch5\u003eNon-Absorbent Palettes Stored While Covered\u003c\/h5\u003e\u003cp\u003eBy simply covering a non-absorbent palette, such as an enameled butcher tray, or placing your palette in an enclosed storage container, even wet mixtures of OPEN Acrylics will stay soft and useable for many days if not weeks. If areas feel tacked up, small additions of OPEN Thinner should easily revive them.\u003c\/p\u003e\u003cp\u003eMisting the palette beforehand with either water or OPEN Thinner will further extend these periods as well as help mixtures of OPEN Acrylics with faster drying GOLDEN Acrylics stay useable. Although both OPEN Thinner and water alone are helpful, OPEN Thinner is generally more effective and is our recommendation.\u003c\/p\u003e\u003cp\u003eThe ability of mixtures of regular GOLDEN and OPEN Acrylic Colors or Mediums to remain useable will be very dependent on the ratios of the mixtures and whether they have been misted with OPEN Thinner or covered with a layer of OPEN Medium. In most cases these should do quite well for a period of days. However, dollops of pure Fluid and Heavy Body Acrylics might become heavily skinned over or not usable during the same period.\u003c\/p\u003e\u003ch4\u003eCLEANING\u003c\/h4\u003e\u003cp\u003eClean tools with soap and water.

Since volatile materials in OPEN evaporate slowly, faster drying layers can easily entrap these materials and delay the time when the layers will fully adhere to each other. While ultimately all layers will coalesce and develop full adhesion, quickly interleafing faster and slower drying layers can cause some of those layers to display early adhesion failure if pulled on, as can happen in hard-edge techniques that use masking tape.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e\u003cem\u003eDo not apply thick films of faster drying gels on top of applications of OPEN Acrylics, Gel, or Medium without waiting for a minimum of two weeks after being touch dry\u003c\/em\u003e.\u003c\/strong\u003eThis extended period is needed to avoid the volatile materials that might still be evaporating from the underlying materials from causing these faster drying gel applications from remaining cloudy or hazy.\u003c\/p\u003e\u003ch4\u003eRewetting OPEN Acrylic Colors\u003c\/h4\u003e\u003cp\u003eOPEN Acrylics can be reactivated for many hours after initial application, allowing for extended periods when multiple layers can be worked and blended into each other. To reopen films before they have fully locked downi, apply OPEN Gel or Medium directly to the paint film, brushing back and forth until the paint has been reconstituted. Even after OPEN paint films have initially set up and become tacky, they can still be reactivated, although more extended or vigorous brushing might be required. Using OPEN Gel or Medium for this process will help maintain film integrity and provide maximum working time. While water and OPEN Thinner are also usable, they are very aggressive at reactivating OPEN paint films and should be used sparingly to prevent partially dried films from lifting altogether.\u003c\/p\u003e\u003cp\u003eTo avoid reactivating underlying paint films, use a light touch when painting over recently worked areas. If one\"s methods require more substantial protection, wait for these layers to lock down, which can take several hours or even days depending on application thickness and environmental conditions.\u003c\/p\u003e\u003cp\u003eTo more quickly isolate layers from potential reactivation by subsequent applications, apply a thin, faster drying coating such as GAC 500, Fluid Matte Medium, or our standard isolation coat recipe of Soft Gel (Gloss) thinned 2 parts gel to 1 part water.

Since volatile materials in OPEN evaporate slowly, faster drying layers can easily entrap these materials and delay the time when the layers will fully adhere to each other. While ultimately all layers will coalesce and develop full adhesion, quickly interleafing faster and slower drying layers can cause some of those layers to display early adhesion failure if pulled on, as can happen in hard-edge techniques that use masking tape.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e\u003cem\u003eDo not apply thick films of faster drying gels on top of applications of OPEN Acrylics, Gel, or Medium without waiting for a minimum of two weeks after being touch dry\u003c\/em\u003e.\u003c\/strong\u003eThis extended period is needed to avoid the volatile materials that might still be evaporating from the underlying materials from causing these faster drying gel applications from remaining cloudy or hazy.\u003c\/p\u003e\u003ch4\u003eRewetting OPEN Acrylic Colors\u003c\/h4\u003e\u003cp\u003eOPEN Acrylics can be reactivated for many hours after initial application, allowing for extended periods when multiple layers can be worked and blended into each other. To reopen films before they have fully locked downi, apply OPEN Gel or Medium directly to the paint film, brushing back and forth until the paint has been reconstituted. Even after OPEN paint films have initially set up and become tacky, they can still be reactivated, although more extended or vigorous brushing might be required. Using OPEN Gel or Medium for this process will help maintain film integrity and provide maximum working time. While water and OPEN Thinner are also usable, they are very aggressive at reactivating OPEN paint films and should be used sparingly to prevent partially dried films from lifting altogether.\u003c\/p\u003e\u003cp\u003eTo avoid reactivating underlying paint films, use a light touch when painting over recently worked areas. If one\"s methods require more substantial protection, wait for these layers to lock down, which can take several hours or even days depending on application thickness and environmental conditions.\u003c\/p\u003e\u003cp\u003eTo more quickly isolate layers from potential reactivation by subsequent applications, apply a thin, faster drying coating such as GAC 500, Fluid Matte Medium, or our standard isolation coat recipe of Soft Gel (Gloss) thinned 2 parts gel to 1 part water. However, as mentioned earlier, this will potentially slow the timeline for the development of full inter-coat adhesion.\u003c\/p\u003e\u003ch4\u003eUsing With GOLDEN Acrylic Colors, Gels and Mediums\u003c\/h4\u003e\u003cp\u003eOPEN Gel and Medium may be mixed in any ratio with nearly the full range of GOLDEN Acrylic Colors, Gels, Pastes, and Mediums.

To reopen films before they have fully locked downi, apply OPEN Gel or Medium directly to the paint film, brushing back and forth until the paint has been reconstituted. Even after OPEN paint films have initially set up and become tacky, they can still be reactivated, although more extended or vigorous brushing might be required. Using OPEN Gel or Medium for this process will help maintain film integrity and provide maximum working time. While water and OPEN Thinner are also usable, they are very aggressive at reactivating OPEN paint films and should be used sparingly to prevent partially dried films from lifting altogether.\u003c\/p\u003e\n\u003cp\u003eTo avoid reactivating underlying paint films, use a light touch when painting over recently worked areas.

Since volatile materials in OPEN evaporate slowly, faster drying layers can easily entrap these materials and delay the time when the layers will fully adhere to each other.

To reopen films before they have fully locked downi, apply OPEN Gel or Medium directly to the paint film, brushing back and forth until the paint has been reconstituted. Even after OPEN paint films have initially set up and become tacky, they can still be reactivated, although more extended or vigorous brushing might be required. Using OPEN Gel or Medium for this process will help maintain film integrity and provide maximum working time. While water and OPEN Thinner are also usable, they are very aggressive at reactivating OPEN paint films and should be used sparingly to prevent partially dried films from lifting altogether.\u003c\/p\u003e\u003cp\u003eTo avoid reactivating underlying paint films, use a light touch when painting over recently worked areas.

Since volatile materials in OPEN evaporate slowly, faster drying layers can easily entrap these materials and delay the time when the layers will fully adhere to each other.

To reopen films before they have fully locked downi, apply OPEN Gel or Medium directly to the paint film, brushing back and forth until the paint has been reconstituted. Even after OPEN paint films have initially set up and become tacky, they can still be reactivated, although more extended or vigorous brushing might be required. Using OPEN Gel or Medium for this process will help maintain film integrity and provide maximum working time. While water and OPEN Thinner are also usable, they are very aggressive at reactivating OPEN paint films and should be used sparingly to prevent partially dried films from lifting altogether.\u003c\/p\u003e\u003cp\u003eTo avoid reactivating underlying paint films, use a light touch when painting over recently worked areas. If one\"s methods require more substantial protection, wait for these layers to lock down, which can take several hours or even days depending on application thickness and environmental conditions.\u003c\/p\u003e\u003cp\u003eTo more quickly isolate layers from potential reactivation by subsequent applications, apply a thin, faster drying coating such as GAC 500, Fluid Matte Medium, or our standard isolation coat recipe of Soft Gel (Gloss) thinned 2 parts gel to 1 part water.

With the extended open time, brushes that have been unintentionally left out for many hours can still be readily cleaned.

(Support Induced Discoloration). This is especially true if working with thicker translucent layers or ones that have been kept wet for extended periods, where moisture has ample time to penetrate into these substrates and allow impurities to be solubized. Because of this, we strongly recommend using MDO (Medium Density Overlay) or furniture grade Birch plywood if wanting to paint on a wood substrate.

Engineered to meet the highest standards of professional airbrush illustrators, High Flow Medium possesses excellent spraying properties and is formulated to minimize tip build-up, clogging and surface defects.\u003c\/p\u003e\u003ch4\u003ePRODUCT APPLICATION\u003c\/h4\u003e\u003ch5\u003eMixing Directions\u003c\/h5\u003e\u003cp\u003eHigh Flow Medium can be blended with GOLDEN Airbrush Colors or High Flow Acrylics in any ratio desired, allowing artists to precisely control of the transparency of the colors. These attributes are very important for techniques such as shading and smooth gradations.\u003cbr\u003e\u003cbr\u003eHigh Flow Medium can also be used with any of the GOLDEN Heavy Body, Fluid, High Load, and Iridescent \u0026amp; Interference Acrylics. When the mixture of Paint and Airbrush Medium exceeds a ratio of 1:2 or more, High Flow Medium can be added to further thin and extend. This will keep the retarder level balanced for a quicker drying film, without sacrificing sprayability . GOLDEN Airbrush Medium is useful to make products spray better, but it can quickly over-compensate the amount of needed retarding agents. Such an overload will hurt the drying and increase the likelihood of Frisket1 pull-up (see below).\u003c\/p\u003e\u003ch5\u003eBlending Suggestions\u003c\/h5\u003e\u003cp\u003eStir gently to ensure homogeneity before blending with GOLDEN Airbrush Colors or High Flow Acrylics. Also mix Airbrush Colors and High Flow Acrylics according to label directions before blending with High Flow Medium. Any ratio of High Flow Medium to Airbrush Color or High Flow Acrylics can be used. Generally, a ratio of 5 to 10 parts High Flow Medium to 1 part (by volume) Color is a useful starting point to yield adequate transparency. Careful blending is required to minimize foam generation, as excessive shaking or stirring readily entraps air bubbles which may result in surface defects.\u003c\/p\u003e\u003cp\u003eWater can also be used with High Flow Medium and the Airbrush Colors or High Flow Acrylics, but doing so will reduce the sprayability and frisket performance that High Flow Medium enhances. When using water with High Flow Medium, a 1:2 ratio of water to High Flow Medium is the maximum amount of water recommended.\u003c\/p\u003e\u003ch5\u003eSpraying Iridescent and Interference Colors\u003c\/h5\u003e\u003cp\u003eBeyond the Iridescent paints offered in GOLDEN High Flow Acrylics, GOLDEN also has a broader range of both Iridescent and Interference colors in Fluids and Heavy Body, and both of these can be reduced with High Flow Medium for spray-applications. Generally, the Airbrush Medium is recommended for reducing Fluid Acrylics, however, testing has shown the reflectance to be higher when High Flow Medium is used instead. The lower level of retarders in the Medium will allow for faster drying times when spraying larger areas with an even film.\u003c\/p\u003e\u003ch5\u003eFrisketing\/Masking Techniques\u003c\/h5\u003e\u003cp\u003eWhen frisketing is of critical importance, GOLDEN High Flow Medium should be used to extend the Airbrush Colors and High Flow Acrylics. This combination dries more quickly, friskets extremely well, and has excellent spray performance. GOLDEN Airbrush Medium also functions as an extender for Airbrush Colors and High Flow Acrylics for applications requiring greater transparency and greater open time (slower drying). Because of the slower drying, using the Airbrush Medium with the Airbrush Colors or High Flow Acrylics may result in poor frisket performance (color pulling up with the frisket or mask), unless the film is completely allowed to dry.\u003c\/p\u003e\u003ch5\u003eDrying Recommendations\u003c\/h5\u003e\u003cp\u003eWhen frisketing or working with loose masks, allow adequate time for the paint film to dry and refrain from using excessive force during frisket application. Generally, a 10-minute drying time is recommended; however, this time can change dramatically in relation to climatic conditions. High humidity (greater than 80% RH) and\/or low temperatures (less than 60oF) will slow the drying process. Low humidity (less than 40% RH) and\/or high temperatures (greater than 80oF) will speed the drying process.\u003c\/p\u003e\u003cp\u003eUse of a hair dryer or heat lamp can be used to shorten drying times, but exercise caution as excessive heat can warp the illustration board, and\/or create air bubbles under any frisket in place, or interfere with film formation and yield a fragile film.\u003c\/p\u003e\u003ch5\u003eGeneral Information\u003c\/h5\u003e\u003cp\u003ePaint on any non-oily surface. Non-absorbent surfaces should be abraded for increased adhesion. Clean tools with soap and water. Keep tools wet during use. Do not allow the product to dry in airbrush.
