    Application steps

    APPLICATION

    The surface to be treated should be clean, dry and free from dirt, dust, oil and grease. All surfaces where bitumen coating to be applied must be thoroughly cleaned.Remove all dust, dirt or contamination. To get sound clean, dry surfaces. All major cracks to be opened in "V" shape & fill it up with repair mortars. Honey combed or spelled concrete to be repaired with a suitable repair mortar. Nail heads and other protrusions that are likely to damage the coating must be removed or grounded.
    Priming: Normally priming is not required, however priming the surface is recommended when the surface is very dry & porous. The priming coat is made by diluting Sika® Bitumen PK with 20-30% clear compatible water.
    Sika® Bitumen PK may be applied by brush or roller or spray machine to prepared surfaces. Stir well before use, replace lid when not in use. For any spillage soak up with sand or sawdust and wash down immediately.
    As damp proof membrane and vapour barrier, two coats of Sika® Bitumen PK are recommended. Allow a minimum 2 hours between the first coat and second coat.
    The second coat should be applied at right angle and ensure that no pinhole is left. All applications should be continued up vertical to the existing damp proof course.
