Brand Ready-Mixed Joint Compounds contain vinyl binders and other ingredients that provide performance
superior to that of ordinary ready-mixed products. Blended to a creamy, smooth consistency, United States Gypsum
Company vinyl-based formulations give excellent slip and bond and easy workability. They can be used directly
from the container, and require only minimal mixing, thinning, and retempering. Joint finishing is fast, easy, and
smooth, reducing labor costs and improving appearance and quality of the job.
BEADEX

Ready-Mixed Taping Joint Compound A high-performance product for embedding tape. Ideal for patching
plaster cracks and for use on most gypsum board when maximum bond and crack resistance are essential. It is
the best ready-mixed compound for laminating.
BEADEX
®
Ready-Mixed Topping Joint Compound A low-shrinkage, easily applied and sanded product recommended
for second and third coats over B
EADEX Ready-Mixed Taping and All-Purpose Compounds. Bond strength, however,
is insufficient for embedding tape or for first coat metal beads and trim.
BEADEX
®
Ready-Mixed All-Purpose Joint Compound Used for embedding and finishing, also for hand-applied simple
texturing. Combines single-package convenience with good taping and topping performance. Also recommended
for skim coating, laminating and repairing cracks in interior plaster and masonry not subject to moisture.
Advantages Ready-mixed convenience and economy Factory-mixed for high quality. Mixing and sanding time are reduced
substantially.
Proper compound for each task A two-compound system for quality joint finishing: BEADEX Ready-Mixed Taping
Joint Compound, for embedding, and B
EADEX Ready-Mixed Topping Joint Compound for second and third coats.
For the convenience of a single compound for both taping and topping, B
EADEX Ready-Mixed All-Purpose Joint
Compound is ideal.
Better slip, excellent bond Compounds feature superior ease of handling, good crack-resistance, and excellent
adhesion. Superior bonding properties are retained by the taping compound even under humid job conditions,
which often weaken bonding of other compounds.
Fewer droppings, less waste Better consistency of these compounds minimizes droppings and reduces risk of
staining woodwork. Costly job cleanup is virtually eliminated. In container, compound can be kept in wet-mix
stage for use months later.
Fewer decorating problems Tests show that BEADEX Ready-Mixed Joint Compounds are especially resistant to
cracking along tape edges. Smoothness of finished joints and lack of any chemical reaction with quality paints
or wallpaper simplify decoration.
Limitations 1. Protect container from freezing and extreme heat.
2. Prior to using any epoxy coating over any surface treated with joint compound, consult the epoxy coating
manufacturer and follow manufacturer’s specific recommendations regarding the preparation or suitability of
substrates for the epoxy coating. Many epoxy coatings exert significant shear stress on the substrate as the
strong epoxy film shrinks while curing/drying. This stress can cause the bond of the joint compound to fail,
resulting in delamination problems.
Preparation Install gypsum panels in accordance with manufacturer’s recommendations.
In cold weather and during gypsum panel joint finishing, temperatures within the building shall be maintained
at a minimum of 55 °F (13 °C). Adequate ventilation shall be provided to carry off excess moisture.
Mix contents lightly without adding water. Use directly from container for covering fasteners and corner bead.
For taping and finishing joints (especially for use in mechanical tools), thin as necessary. Add water in half-pint
increments to avoid overthinning. Remix lightly and test apply after each water addition.
