Ceresit CR166 Two-component Flexible Waterproofing Slurry - Bucket

Ceresit CR166 is a two-component flexible slurry, strengthened with fibres and designed for waterproofing and damp-proofing on on walls, floors and ceilings. It can be used on deformable and non-deformable mineral substrates. Its flexibility allows it to bridge ≥ 0,75 mm wide cracks – even in cold conditions. Ceresit CR166 waterproofing coating delays the carbonation process and provides effective anti-corrosion protection for concrete/reinforced concrete land and water structures.

• Mix until homogenous, let the slurry mature for 5 min. and mix shortly,
• Apply 1st layer of CR 166 with brush​,
• Fix the tape (e.g. CL 152) into fresh 1st layer in places of expansion joints, inner corners or joints between different material types​,
• Adjust consistency to relevant application tool,
• Apply subsequent layer of CR 166 with trowel or roller,
• When covering a large areas, it is possible to apply CR 166 with a spray gun,
• As a final step, smooth the surface with a trowel,
