APPLICATION NOTES:
- MC-Grout is used to counteract the normal shrinkage of mortar and concrete. MC-Grout has selected and pre-mixed aggregates to produce a homogeneous, stable, and water-free mixture. Consumption: 76 – 78 bags for 1m³ mortar (depending on the water amount while mixing).
- If pouring mortar into large cavities: Depending on the size and thickness of the mortar layer, large aggregates can be added to MC-Grout mortar: For example, with diameters of 4-6mm, 8-16mm with a mass equal to 50% to 100% of the dry mass of MC-Grout. Ensure that the thickness of the poured layer is at least 3 times the largest size of the added aggregate. When constructing thicknesses > 60mm, adding large aggregates and using cold water will reduce the temperature generated during the initial setting process.
- Substrate preparation:
– Before construction, concrete surfaces must be clean, free of oil, grease and dirt. Metal surfaces must not rust. No standing water.
– After roughening the concrete surface, the surface must be saturated with moisture. - Mixing:
– Use an appropriate mixer and do not mix by hand. Allow 3 minutes mixing time to get a mixture showing homogeneous consistency.
– Leave the mixture for about 3-5 minutes to reduce the air holes and the chemical components to work together.
– Placing the grouting material as soon as possible after mixing to gain full benefit, and keeping mortar flow uninterupted. - Curing: Curing the exposed surface of the grout as soon as the surface is dry, avoiding the rapid loss of water causing cracking and reducing the quality of the mortars.
- Cleaning: Use clean water to clean tools immediately after application. When the product is solidified, it can only be cleaned by mechanical methods.
- Safety information:
– The product does not contain toxic substances, safe to use with construction safety principles. For example, use gloves, safety glasses, …
– Avoid contact with food and utensils, avoid prolonged contact with skin. In case of contamination, wash thoroughly with water. If splashed into eyes or mouth, wash thoroughly with clean water and seek medical assistance immediately.
