Bestgrout CE400 Vữa rót không co ngót cường độ cao gốc xi măng Mác 400 – bao 25kg

Surface preparation:​

• The surface must be clean, solid, and free from grease or impurities, and must be treated as leaking before (if any). The water absorption surface must be saturated to avoid water loss locally and reduce the flow of materials in the application process.

Mixing:

• BestGrout CE400 powder is added slowly to the mixing water to achieve flexibility (viscosity) as required. However, typically, the optimum mixing water is 13% compared to the weight of powder (3.25 liters of water per 25 kg bag of BestGrout CE400). Use a paddle mixer with a speed of 500-600 revolutions /minute to mix the compound until achieving the homogeneous as required (about 3 minutes).

Applying:

• After mixing, use an iron trowel to stir lightly for a few seconds to release air bubbles. Then, pour the compound immediately into the prepared framework continuously to maintain the pressure necessary for filling the material layer to avoid air entrapment in the structure.
• Notes: The framework must be checked and guaranteed not to leak water during application and before the compound gets cured. Do not use materials that application time over.

Important notes:

• The product is applied to the minimum clearance of structure is 8 mm Curing procedures should be ensured strictly as products originating from other cement.
• When applying to large structures with a thickness greater than 60 mm, to save materials and reduce the heat of hydrolysis, hydration should add large aggregates carefully selected ( such as gravel, small stone 1×1) which is the quantity from 50÷100% and the mixing water is not over 14% to the initial weight of BestGrout CE400. Should be tested before application.

Cleaning:

• Clean tools and equipment with water before the mixed grout hardens.

Safety:

• BestGrout CE400 is alkaline like normal cement and can cause skin irritations to persons with sensitive skin. Wear gloves and masks while handling the product. In case of accidental eye contact, wash with fresh water and seek medical advice immediately.
