GOLDEN - Crackle Paste (237ml)

GOLDEN - Crackle Paste (237ml)

Acrylic painting medium Designed to develop deep fissure-like cracks Water-based Cleans up with soap and water Made in the USA Video: Golden Artist Colours - Exploring Crackle Paste Golden Crackle Paste is a thick, opaque cracking material, designed to develop deep fissure-like cracks as it cures. The size and extent of the crackle pattern is dependent on many factors, including the thickness of application, and the environmental conditions (temperature, relative humidity and air flow) during drying. This product utilises defects in the film formation process, and controlled failure is problematic. This results in the cracking performance being variable and to some extent unpredictable. Golden has provided the most current and comprehensive knowledge of what may be expected while using this product, but artist-conducted testing will ultimately assure more reproducible and sound applications. Crackle Paste is a water-based product formulated with styrene-acrylic copolymer emulsions, and may have a tendency to yellow. This product has white, low-density solids that replace traditional fillers. Its unique ratio of specific solids and binders allows for a "controlled failure" to occur and the result is its tendency to crack. It has a consistency similar to cake icing, easily manipulated by a palette knife. Peaks will maintain their height and appearance. It is a harder film than the GOLDEN Light Moulding Paste, yet still retains an absorbent surface. Films dry to an opaque, matte finish to which subsequent layers of acrylic paint and mediums can be applied. Crackle Paste can be easily tinted with Golden Heavy Body, Matte, High Load and Fluid Acrylic Paints. It is imperative to test all aspects when working with Golden Crackle Paste. This is a highly variable product, and it should NOT be assumed that it will perform exactly the same each time the product is used. Review this information carefully and conduct testing before using this product on artwork or decorative finishes. Drying times greatly depend upon film thickness. Very thin films will dry to the touch in several hours but may not develop much cracking. Increasing film thickness will increase the tendency to crack and also the size of the cracks and platelets. Cracks can take several days to fully develop. Do not force dry Crackle Paste, nor try to slow the drying by adding Retarder or other additives, as both conditions may interfere with the products ability to crack. Product should be allowed to cure between 65oF and 75oF, and under 75% Relative Humidity. Crackle Paste cleans up with soap and water. Do not let products dry on tools. Keep tools wet while in use. Soak tools in soapy water to remove dried films. About Golden Mediums Golden offer the widest range of mediums for acrylic painting.

GOLDEN - Isolation Coat (237ml)

GOLDEN - Isolation Coat (237ml)

Acrylic painting medium Physically separates the paint surface from removable varnish Seals in absorbent areas Creates an even surface for varnishing Made in the USA Video: Golden Artist Colours - Isolation Coat Application For Small Paintings An isolation coat is a clear, non-removable coating that serves to physically separate the paint surface from the removable varnish. The isolation coat serves two purposes:to protect the painting if/or when the varnish is removed by separating the pigmented area of the painting from the solvents used in removal; and to seal any absorbent areas in order to create an even surface on which to apply the varnish. An isolation coat can be very beneficial to the preservation of a piece of artwork but it is not for every painting. The decision of applying an isolation coat is first an aesthetic decision: Will this serve the purpose of the work? Secondly, are the changes created by the application of an isolation coat and subsequent varnish understood and anticipated? These are important questions to consider as the isolation coat will become a permanent part of the painting. Some ways that an isolation coat may negatively affect the underlying painting are: Foam and bubbles resulting from mixing Soft Gel (Gloss) and water too vigorously. Brushstroke texture Change and/or loss of texture Change or shift of colour Testing and practice should always be done before application to insure that the isolation coat will not change or damage the piece in any way that is undesirable. Here are a couple of examples of pieces that should not receive an isolation coat: Oil paintings Any painting done with water soluble media A piece with intentional varying sheens and surface qualities Work with metallic leaf (imitation gold leaf can tarnish with exposure to gels and paints) Sealing absorbent surfaces of the painting with an isolation coat will assist in the varnish application. This will prevent the varnish from being absorbed within the surface and allow the varnish to function as an easily removable topcoat. This is especially important when using a Satin or Matte varnish because the liquid of the varnish can be absorbed into non-sealed areas leaving the matting solids exposed at the surface and creating a dusty or cloudy appearance. To determine if you have a substantial isolation coat, once the first isolation coat is dry, look at the painting at an angle and the presence of an even sheen should indicate an even surface ready for varnish.
