Golden Proceed

Manufacturer:  Golden

Product Name:   PROCEED™ Full Bodied Painting & Glazing Medium

PROCEED™ Painting & Glazing Mediums are designed for interior decorative applications, such as faux finishing, wood graining, and Trompe L'Oeil murals.  They are intended to be used in conjunction with other PROCEED decorative products, including the PROCEED Slow-Drying Fluid Acrylics and PROCEED Pigment Dispersions.  PROCEED Painting & Glazing Mediums’ thixotropic nature and other attributes offer artists oil paint-like properties without the need for solvents and the excessive drying times.

PROCEED Painting & Glazing Mediums are thixotropic waterborne painting mediums designed for easy blending and exceptionally long working time.  They are produced with Acrylic Polymer Dispersion, producing a film with excellent flexibility, and chemical, water, and UV resistance.  Thixotropic products have excellent leveling when working –them and quickly “set-up”, becoming more viscous on the palette and substrate, facilitating easy palette management.

Golden offers 2 types of Painting & Glazing Mediums:  PROCEED Full-Bodied Painting & Glazing Medium and PROCEED Low Viscosity Painting & Glazing Medium.

PRODUCT APPLICATION
NOTE: Before opening containers of PROCEED Painting & Glazing Medium; vigorously shake the container to make the product homogenous and smooth.  Failure to properly shake the product will result in lumps and an uneven consistency.

PROCEED Full-Bodied Painting & Glazing Medium sets up to a thicker consistency when left undisturbed and offers better control of material on the palette.  Tool marks made in glazed surfaces do not diffuse and remain crisp until softened.  This material is also less likely to drip and run from application tools when working on broad wall and ceiling applications.

PROCEED Low Viscosity Painting & Glazing Medium, is formulated at a thinner “at rest” consistency and is more “oil like” in its consistency.  The two mediums can be blended together at any ratio to adjust the consistency of the working mixture as needed.

Update 11-19-2007
The formula for this product has been revised.  This revision dramatically improves this product in terms of it's intend use as a painting and glazing medium for fine, detailed decorative techniques such as graining, marbling, striping, trompe l'oeil, and

ornamentation over relatively non-absorbent surface preparations. 
Specific changes in product performance are:

• Improvement in wet-state clarity
• Dramatic extension of open time (up to one-hour working time under most conditions)
• More “oil-like” application characteristics
• Improvement of overnight strap down
• Accelerated through-dry time (typically 48-72 hours)

Mixing with PROCEED Slow-Drying Fluid Acrylics
PROCEED Painting & Glazing Mediums can be mixed in any proportion with the Slow-Drying Fluid Acrylics to adjust the pigment load and the overall transparency of the mixture.  These paints may be blended with either PROCEED Painting & Glazing Medium in any ratio to achieve the desired working properties.  Blending with PROCEED Low Viscosity Painting & Glazing Medium will alter the viscosity of the final blend.  Blending with PROCEED Full-Bodied Painting & Glazing Medium will not.

Mixing with PROCEED Pigment Dispersions
PROCEED Pigment Dispersions are concentrated organic and inorganic colorants with a very low binder level.  This dispersion line differs greatly from Universal Tinting Colorants (UTC’s) as they are not glycol based and are made with the same resin as the other PROCEED products.  Therefore, do not use UTC’s with this product line.
We recommend using PROCEED Slow-Drying Fluid Acrylics to tint the painting and glazing mediums for glazing and color washing applications.  Alternatively, PROCEED Pigment Dispersions can be used.  Caution should be exercised with dispersions, as the dispersion level should not exceed approximately 20% by volume of any mixture.  Over adding dispersion can affect “strap-down” time (the time it takes before a paint film is dry enough to be recoated), water/solvent sensitivity, and working times.

TOPCOATING INSTRUCTIONS
The strap-down time for mixtures using PROCEED Painting & Glazing Medium is 48 hours.  After this time period, the paint film should be water resistant and avoid moving when coated, but care should be given, as it will take up to four weeks or more to achieve its best water resistance.

WORKING PROPERTIES
Working Time
Working Time is typically 15 to 45 minutes, depending on a number of factors.  The nature of the technique used, whether additive (sponging, ragging on, etc.) or subtractive (stippling, ragging off, etc.), will vary the working time considerably.  Environmental factors such as humidity, temperature, absorbency of surface and air circulation also impact the amount of open time.  Allow 15-60 minutes for the paint films to dry before attempting any over painting.

NOTE: Very glossy surfaces will offer the maximum open time, but the product may not have proper adhesion, and may also creep/crawl as it dries.  Avoid direct application onto slick surfaces whenever possible.

The films reactivate and are reworkable for several hours with water or more glaze depending upon conditions, and can remain resoluble for up to 24 hours in certain conditions.  Naturally, the longer the products are allowed to cure, the less soluble they become.  Subsequent layers can be gently applied over the paint films, but more aggressive applications and tool use will solubilize and subsequently lift the paint films from the surface.  If these kinds of techniques are required, simply allow more time for the paint to set up before continuing with the application.

Work on walls and other surfaces base painted with at least two coats of a high quality acrylic architectural coating for maximum working time (see Increasing Working Time section below).  This is vital when working on new wallboard, as the layers of semi-gloss paint will dramatically reduce the absorption of water and retarder in the PROCEED Painting & Glazing Medium, resulting in a greater working time.

Increasing Working Time

1. Surface absorbency affects working time.  Sealing the surface, ideally with a gloss base, allows for maximum working time.  Matte paints, such as flat house paint or artist's gesso, soak up vehicles quickly, thus reducing working time.  Any air movement flowing over the surface will make acrylic paints and glazes dry more quickly.  To maximize the working time, cover or close vents or windows, which blow air directly across the surface.
2. Weather conditions greatly influence working times.  Hot, dry climates and direct sun exposure will reduce working time.  Ideal conditions for maximum working times are cool, rainy, high humidity climates.
3. Adding Golden Artist Colors’ Matte Medium or Polymer Medium will speed the drying time of Proceed Slow-Drying Fluid Acrylics.

COVERAGE
PROCEED Painting & Glazing Medium will cover 400-2,000 square feet per gallon for typical wall glazes, depending on techniques from brushing on to sponging.

THINNING
Thinning PROCEED Painting & Glazing Medium with water is not suggested and not normally required.  These products are balanced blends of materials, and while water can be added to these products, it will affect the working properties such as the thixotropic nature and film strength.  Limit water addition amounts and add only when in a low humidity and high temperature environment to achieve the proper working properties.
