Product Summary
Construction and Materials
National Gypsum Company offers a range of finishing and setting compounds designed for professional drywall applications. These products are formulated to provide durable, smooth surfaces ready for painting or texturing.
Construction and Materials
The primary construction of these compounds involves gypsum, a naturally occurring sulfate mineral. This gypsum is processed and combined with other additives to create the various formulations available.
- Gypsum Base: The core component of all compounds.
- Additives: Specific formulations include various chemicals to control properties such as:
- Setting time
- Workability
- Bonding strength
- Shrinkage
- Water retention
Product Categories and Applications
National Gypsum's compounds are categorized to suit different stages of drywall finishing and specific performance requirements:
- Ready Mix Compounds: These are pre-mixed, all-purpose compounds designed for ease of use. They are suitable for taping, filling, patching, and skim coating. Their formulation typically allows for good adhesion and easy sanding.
- Setting Compounds: These are powder-based compounds that are mixed with water on-site. Setting compounds offer a harder finish and faster set times compared to ready-mix, making them ideal for heavy fills, embedding joint tape, and filling larger cracks or holes. They are known for their minimal shrinkage and excellent strength.
- Fire Smoke Stop Compound: Specifically engineered for fire-rated assemblies. These compounds are designed to maintain the integrity of fire-rated walls and ceilings, contributing to smoke and fire containment. Their formulation is critical for achieving required fire resistance ratings.
- Textures: Compounds designed to create decorative surface finishes. These can be applied to drywall or plaster surfaces to add visual appeal and hide imperfections. The materials are formulated to allow for various application techniques, such as spray, roll, or trowel application, to achieve different texture patterns.
