How do I mix Waterseal Non Shrink Grouting Powder?
To prepare the master mix, combine 20 Kg Non Shrink Grouting Powder with 15 litres of clean water and 5 litres of Waterseal PSV Premix. Mix thoroughly until a smooth, lump-free slurry is obtained. Use the required quantity immediately for core filling or grouting applications.
How much area does one 20 Kg pack cover?
One 20 Kg pack can typically fill approximately 6 standard pipe core cuts. Actual coverage depends on the pipe diameter, core cut width, depth, and the amount of material required for complete filling.
How long does Non Shrink Grouting Powder take to set?
Waterseal Non Shrink Grouting Powder has an initial setting time of approximately 30–40 minutes under normal conditions. Setting time may vary depending on the ambient temperature, humidity, and the quantity of water used during mixing.
Can Waterseal Non Shrink Grouting Powder be used for waterproofing?
Yes. When used together with Waterseal PSV Premix Waterproofing Chemical, it provides a strong, crack-free, and waterproof seal around pipe penetrations, drainage outlets, expansion joints, and core cuts, helping prevent future water seepage and leakage.
How much Waterseal PSV Premix is required for one 20 Kg pack of Non Shrink Grouting Powder?
For one 20 Kg pack of Waterseal Non Shrink Grouting Powder, we recommend using one 5-litre pack of Waterseal PSV Premix along with 15 litres of clean water to prepare the master mix.
