    Mainly performance differences
    C1 bond strength ≥ 0.5Mpa
    C2 bond strength ≥ 1.0Mpa

    Our tile adhesive recipe:
    42.5 cement 400 kg,
    Quartz sand 40-70 mesh 450 kg,
    70-140 mesh 150 kg,
    HPMC 100000cps 3 kg,
    RDP 18 kg,
    PVA 1.5 kg,
    Wood fiber 1 kg,

    Posted marble tiles 800X800 problem? If the inspection can pass C2 Level?

    C2 certainly can not. C1 this amount of RDP should be able to achieve.
    Polished tiles 800x800 certainly not, we have tried

    The main difference is to measure the bond strength index, C1 bond strength is greater than or equal to 0.5Mpa, and C2 bond strength is greater than or equal to 1.0Mpa. Generally, small brick with C1-type tile adhesive, stickers more than 800x800 tiles with C2-type tile adhesive.
