Main purpose

Airtight sealing tape for sealing membrane to window frames, to door frames and to masonry walls, floors and ceilings. Can be plastered over.

Use it on

Internal wall, floor or ceiling junctions.  Permanently sticks to concrete, stone or masonry. Also to timber, PVC, wood or aluminium windows and doors and all Pro Clima airtight membranes. 


Pro Clima Contega Solido SL is an interior airtight tape designed for airtight sealing of window and door frames and also sealing membranes at masonry junctions (wall to floor, wall to ceiling) prior to wet plastering over.  Its fleecy backing gives an excellent key for wet plaster.  

Where to use it

Contega Solido SL will permanently stick to stable concrete, plaster, masonry,  blockwork, bricks, timber, PVC or aluminium.  Use it where the window and door sealing tape used  will be plastered over and when you will apply the tape to the windows and doors that have already been installed into the building (post-installation sealing).

What it does

Passivhaus certified as part of the Pro Clima Intello Plus system, Contega Solido SL is specifically designed for the airtight sealing of windows and doors and also masonry wall junctions. It will seal the gap between a window or door frame and the wall or a Pro Clima membrane and a wall to ensure there will be no air leakage. 

When doing the airtightness detailing for a loft or suspended timber floor insulation refurbishment, Contega Solido SL is ideal for sealing the perimeter of the membranes to masonry walls that have been primed with Pro Clima Tescon Sprimer

Contega Solido SL has a fleecy top layer which is an excellent key for plaster to be applied over the top. The plaster applied to the interior side of the wall (covering the tape) completes the airtight seal for the window or door.  

Why we love it

Installing  Contega Solido SL to the windows after installation makes the sealing of windows and doors neater and easier.  With  Contega Solido SL, the seal is made after the window or door is installed so up to 20mm of the tape will be stuck to the front surface of the frame. 

Contega Solido SL is a perfect alternative to the common use of expanding foam around windows and doors. Foam, is a gap filler, and may not be permanently airtight and may degrade after a period of time.  Contega Solido SL is fully airtight and permanent. 

Window and door openings are one of the main culprits for air leakage; the correct sealing of these openings will ensure your the overall airtightness of the building will not be compromised.

Contega Solido SL is also an excellent tape for sealing masonry wall junctions prior to them being wet plastered.  Very often when wet plaster is used as an air tight layer,  subsequent cracking can occur at junctions (wall to floor, wall to ceiling).  The application of Contega Solido SL at junctions prior to wet plastering means that even if cracks occur at the junctions, then the junction remains is still air tight.

Installation Guide

In the majority of cases, Contega Solido SL is installed after the door/window has been fitted. Ensure the frame of the door/window is clean and free from dust and grease. Remove the backing from the 20mm section.  

Peeling back the 20mm section
Removing the second release strip

Adhere 20mm of the tape onto the front internal face of the window frame and the remainder back to the reveal.

Use a Pressfix tool to make sure the tape is strongly bonded to the frame.  When the window/door is installed in the building, make sure the reveal (where the tape will be stuck) is clean and free of dust.  If the surface is crumbly or produces dust, use Tescon RP Primer or Tescon Sprimer to stabilise the surface and obtain the best permanent adhesion.

Adhesion back to the window reveal

Remove the backing release paper gradually and firmly press the tape to the reveal with a Pressfix tool. The full area contacting the reveal should have pressure applied to it to ensure a strong bond is made between the tape and the blockwork/concrete of the reveal.

The width of the adhesive tape that is to be plastered over should generally not exceed 60 mm (2 3/8") or 50% of the soffit area.

Hints & Tips

Hints & Tips

The use of Tecscon RP Primer or Sprimer on the reveal is always recommended to ensure the surface is in an ideal condition for a perfect bond that will not be compromised.

Particular care is needed to ensure too much tape is not applied to the window/door frame as it will extremely difficult to remove at a later stage.
