• Scenario 1: The "Missing Layer" Fix

    A common problem in renovation is discovering that the previous builder skipped the Vapour Control Layer (VCL). The result? Moisture gets into your insulation, and heat gets out.

    The Solution:
    You don't need to demolish the wall. You can apply Passive Purple directly onto your existing painted plasterboard.

    • No Demolition: Save thousands by leaving the existing plasterboard in place.
    • Seamless Seal: Roller or spray the Passive Purple over the wall and ceiling. It
      creates a new, robust vapour control layer right on the surface.
    • Paintable Finish: Once the Passive Purple is dry (and turned purple/black), you can decorate directly over it.
    • Option A: Paint it with your chosen emulsion.
    • Option B: Skim over it.
    • Option C: Wallpaper it.
  • Scenario 2: The Masonry Retrofit (Dot &Dab)

    If you are stripping a room back to the bare brick or block, you need to seal the masonry before you put new plasterboard up.

    The Challenge:

    Passive Purple creates a smooth, rubber-like skin. Standard "Dot & Dab"
    adhesive (drywall adhesive) struggles to stick to smooth surfaces.

    The Solution: The SuperGrip System

    We have a simple 3-step system to ensure your plasterboard sticks like rock.

    1. Seal the Wall: Spray or roll Passive Purple directly onto the bare masonry/blockwork. This stops air leaking through the mortar joints.
    2. Prime for Grip: Once the Passive Purple is dry, apply Intelligent Membranes SuperGrip Primer. This adds a gritty, textured "key" to the surface.
    3. Dot & Dab: You can now apply your dabs of adhesive directly onto the SuperGrip layer and install your plasterboard with confidence.

Why Retrofit with Passive Purple?

  • Stop the Drafts: Old brickwork is porous. By sealing the masonry, you stop cold air from permeating your home.
  • Save Space: Traditional timber battens and membranes eat up floor space. Passive Purple is microns thick.
  • Versatile Finishing: Whether you are painting over it or boarding over it, the product works with your renovation plans, not against them.
