Gypsum veneer base, or “blue board”, is similar to standard interior drywall, and like other types of drywall it is manufactured to comply with ASTM C1396. It typically contains blue-tinted paper on one side to differentiate it from other types of drywall, and is designed to be used as a substrate for the application of gypsum veneer plaster. The paper facing is treated to help the plaster adhere to it, and to maintain its strength after absorbing water from the plaster. There is little disclosure on the composition of these treatments, but patent literature indicates that the increased adhesion can be achieved through incorporation of gypsum in the face paper.
Similar to other types of drywall, gypsum veneer base is available in Type X, Type C, and lightweight boards. Foil-backed products are also available for use on the interior face of exterior walls, where the foil functions as a vapor retarder. This Common Product describes a standard 1/2-inch gypsum veneer board. For details on the plaster component see the Gypsum Veneer Plastering Common Product.

All Contents
This is not necessarily representative of all possible content that may be found in this product type. It includes all of the potential content identified during the research process for this Common Product profile. All Content data goes beyond the most common chemicals and materials to provide a more comprehensive representation of what may be found in specific product types. It does not necessarily include all chemicals and materials that may be used by all manufacturers and should not be used as a replacement for a specific manufacturer's product disclosure.
About Process Chemistry
Pharos process chemistry does not necessarily represent all chemicals that may be
used in the production of a chemical or material and may list chemicals that are not
used in all manufacturers' processes. We recommend using Pharos process chemistry as a
starting point in conversations with product manufacturers and chemical suppliers to
determine process chemicals that are relevant to specific products, including known
and potential impurities and residuals. For more information see the
Pharos system description.
A Common Product profile (CP) is a list of substances that are most commonly present in a product type (vinyl composition tile, for example) as delivered to building sites in North America. The profiles are not specific to any manufacturer.
CPs are organized by chemical function. Every substance in a product performs some function - for example, it thickens a paint, or gives a carpet resistance to stains. The CPs provide the most common substance serving each function in a given product type, the hazards these substances carry into a building project, and a general description of the product type. CPs are based upon a wide range of publicly available information, including product declarations, patents, and chemical suppliers' brochures that detail the functional uses of various additives.
For those wanting more than the most common chemical for each function, Pharos subscriptions provide access to the full catalog of possible ingredients that we’ve found may be in products. Where available, these are displayed in the All Contents tab.
The GreenScreen® for Safer Chemicals™ is a benchmarking system to rank the safety of chemicals on a 4 point hazard scale and encourage progress toward safer alternatives. Chemicals that have undergone a full GreenScreen® Assessment™ by Licensed GreenScreen Profilers are given a GreenScreen Benchmark™ score, which is the most authoritative. Chemicals that have been screened using an automated comparison to hazard lists are given a GreenScreen List Translator™ score, which is less authoritative. Full GreenScreen Assessments trump results from List Translator scoring.
GreenScreen scores in order from highest concern to lowest concern are:
