Usage Instructions

To ensure the best results when using Cement, follow these step-by-step usage instructions. This high-strength cement is ideal for solid and hollow casting applications, including lamp bases, thin sections, and other intricate designs. As a capping compound, it meets ASTM C617 and AASHTO standards for strength and performance. For information on cement soundness and expansion, see the ASTM C151 test method, which is also important for evaluating cement properties.

1. Preparation: Before starting, make sure your workspace is clean and dry. Wear protective gloves, safety glasses, and a dust mask to avoid any potential health hazards. White Cement is a high-strength stuff, and proper precautions should be taken.

2. Mixing: To mix the Hydrocal White Gypsum Cement, slowly add the powder to water in a well-ventilated area, following the recommended water-to-powder ratio. Mix thoroughly until the mixture is smooth and free of lumps. The viscosity of this compound makes it easy to pour and excellent for capturing fine details.

3. Application: For casting, apply the mixture to the mold, making sure to fill it completely. For solid casting, pour the mixture into the mold, and for capping, apply a thin layer to the surface. The high green strength of Hydrocal White Gypsum Cement makes it suitable for thin sections that require durability.

4. Setting Time: Allow the mixture to set according to the recommended setting time. The gradual setting time and long plasticity of this white cement provide an extended working time, making it easier to work with.

5. Demolding: Once set, carefully remove the cast from the mold. If necessary, use a soft brush or cloth to remove any excess stuff. The gypsum capping can reach a high strength of 5,000 to 9,000 psi (350 to 630 kgf/cm²) within around 30 minutes, making it a fast and efficient method for preparing concrete compression test samples.

6. Finishing: For a smooth finish, use a fine-grit sandpaper to sand the cast. If desired, appy to protect the surface or enhance the appearance. Hydrocal White Gypsum Cement is compatible with many materials and can be used as over other materials or poured into molds.

7. Storage: Store any unused Hydrocal White Gypsum Cement in a cool, dry place, away from direct sunlight and moisture. Keep the bag tightly sealed to maintain the quality of the compound.
