Gold Bond® Moulding Plaster

Product catalog summary

Finish Plasters Overview: Gold Bond Gauging Plaster is available in quick set or slow set types and is designed for use with finish lime. It is a specially ground, calcined gypsum that mixes readily with water and lime putty. Proper proportioning is essential as gauging adds strength and hardness to the finish surface, reinforcing the lime against shrinkage and cracking. A finish coat of gypsum gauging plaster and finish lime, mixed at a ratio of 2 parts hydrated lime to 1 part plaster by weight, is primarily for interior smooth trowel application over a gypsum basecoat.

Mill-Mixed Finish Plasters: Products like Kal-Kote Smooth Finish, Kal-Kote Texture Finish Plaster, Uni-Kal Veneer Plaster, or X-KALibur Extended Set Veneer Plaster require only the addition of water. Smooth finish plasters should be applied at a thickness of no more than 1/16", while texture finishes should not exceed 1/8".

Specifications: The products comply with ASTM Designations C 28 and C 59. Application of plaster should follow ASTM C 842 standards.

Technical Data:

Gypsum Gauging Plaster: Coverage is 1000-1400 sq. yds./Ton (921-1290 m2/Metric Ton) or 113-158 sq. ft./Bag (10.5-15 m2/bag).
Gypsum Moulding Plaster: Similar coverage as gauging plaster.
Mill-Mixed Finish Plasters: Kal-Kote Smooth and Texture Finish cover 650-750 sq. yds./Ton (598-645 m2/Metric Ton), while Uni-Kal and X-KALibur cover 600-665 sq. yds./Ton (553-613 m2/Metric Ton).

Physical Properties of Basecoat Plasters: The document provides typical test results per ASTM C 472, including compressive and tensile strengths for various plaster mixes.
