Ref. 01486 Preparation

Imperblock Imprimación

Water-based clear primer

Prepares the substrate before waterproofing: penetrates and seals porous surfaces and ensures adhesion even on low- or non-absorbent substrates. Essential prior step for the polyurethane system.

Recommended CPP system In waterproofing the substrate determines whether a primer is needed, how many coats and which membrane. Adhesion is the system's critical point.
  • Roof concrete and mortar Mineral

    Porous and alkaline. Needs full curing and no rising damp; otherwise the membrane blisters when it heats up.

    CPP system: Imperblock Imprimación + Antigoteras, Fibrado or Membrana Hybrid.

  • Aged bituminous membrane Bituminous

    Oxidised, with loose gravel and open overlaps. It can bleed through and stain light finishes if not sealed.

    CPP system: Overlap repair + Imperblock Antigoteras in 2 cross-applied coats.

  • Ceramic and stoneware tiles Non-porous

    No absorption: without a primer the membrane will not bond. Water ingress concentrates at the joints.

    CPP system: Imperblock Imprimación + Fibrado or Membrana Hybrid.

  • Fibre cement and metal sheeting Non-porous

    High thermal expansion and risk of rust at fixings and overlaps. Degrease and treat rust before waterproofing.

    CPP system: Rust treatment + Imperblock Fibrado with reinforcing tape at overlaps.

  • Old acrylic waterproofing Repaint

    If it retains cohesion it is a good substrate; if it is powdery or detached it must be removed completely.

    CPP system: Adhesion test + reinforcement with Antigoteras or Fibrado.

  • Parapets, junctions and drains Detail point

    They account for 90% of water ingress. Sharp edges and right angles tear the membrane due to lack of radius.

    CPP system: Cove fillet, minimum 15 cm upstand and mesh reinforcement.
