Main purpose

To create a flexible airtight and windtight seal between membranes and uneven surfaces.

Use it on

Concrete, brick, plaster, timber, hard plastic, rust-proof metal, chipboard, OSB, plywood and MDF internally or externally.


Orcon F is a multi-purpose airtight and windtight flexible adhesive sealant for sealing membranes and airtight components internally and externally. It remains flexible and will not crack or breakdown over time.  This ensures a permanent airtight seal can be achieved especially on uneven surfaces and on difficult or hard-to-tape areas.

Where to use it

Pro Clima Orcon F airtight sealant can be used on concrete, brick, plaster, timber (smooth planed, rough sawn and painted), hard plastic, rust-proof metal, chipboard, OSB, plywood and MDF to seal all types of absorptive airtight and windtight membrane.

What it does

Orcon F will permanently stick internal or external airtight and windtight membranes to any surface commonly found on a building site. It is commonly used and ideal for sealing airtight membranes (airtight vapour checks) to concrete floor surfaces.

With its high resistance to adverse weather conditions, the adhesive can be stored in low temperatures in the event of frost or freezing conditions (down to -20°C).  It can also be applied to plaster and concrete that has set but not yet fully dried.  

When applying a 5-8mm bead of Orcon F: The 310ml cartridge can seal 6-15m. The 600ml foil tube can seal 12-30m.

How it works

The powerful acrylate based adhesive glue penetrates deep into surfaces ensuring an airtight adhesive bond is maintained at a molecular level.

Why we love it

Orcon F is very elastic remaining permanently flexible to ensure superior protection of airtight connections for the lifetime of a building.  Orcon F, unlike other standard silicone type caulking, won’t harden, crack or become brittle and cause air leakage at critical junctions.

It provides airtight bonds according to DIN 4108-7, SIA 180 and OENORM B 8110-2 and is also Passivhaus certified in conjunction with Pro Clima Intello Plus membrane and Tescon Vana tape achieving the best system airtightness results ever achieved.   

It also achieved excellent values in the hazardous substance test, has been tested according to the ISO 16000 evaluation scheme.

How to Install

Make sure the area is brushed to remove dust/debris and is free of any water repelling contaminants like grease or silicone. Apply a 5-8mm bead on the surface you will be bonding to.  It is important not to flatten the bead completely when sticking an airtight membrane to it; this ensures long term elasticity.

When applying to concrete floor screed and rough uneven concrete slabs, it is recommended to prime the area first with Tescon Primer RP or Tescon Sprimer to ensure enhanced adhesion.

Thanks to its very high adhesion and excellent quick drying time, no pressure lath/timber baton is required. If blown-in insulation will be used, a baton should be installed to prevent the weight or pressure of the insulation pulling on the adhesive.

Hints and Tips

If you ever need to seal a membrane to a floor without using tape; for example with Pro Clima DA-S, we would recommend using the 600ml foil tube, large applicator gun and a double nozzle.  This nozzle will apply two beads side-by-side, one on the floor and one on the membrane, at the same time.
