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.

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.
