Pro Clima Orcon F is a versatile sealant that creates airtight and windproof seals. It is a flexible, adhesive sealant that can be used indoors and outdoors to seal membranes and airtight components, lasting up to a century. Its flexibility prevents cracking and deterioration over time, ensuring a durable, permanent seal, especially on uneven or challenging surfaces.

Uses

This acrylic sealant is suitable for sealing airtight and windproof membranes on various substrates such as concrete, brick, plaster, wood, hard plastics, rust-resistant metals, chipboard, OSB, plywood, and MDF. It effectively bonds these surfaces for reliable airtightness.

Functionality

Orcon F creates a lasting bond between airtight membranes and building surfaces, making it ideal for sealing vapour barriers to concrete floors and other common construction surfaces. Its elastic properties allow it to remain flexible throughout the building’s lifespan, maintaining airtightness at critical junctions without hardening or cracking like traditional silicone caulks.

Application Instructions

Clean the area thoroughly, removing dust, debris, grease, or silicone residues. Apply a bead of 5-8mm thickness to the surface, ensuring it isn't flattened entirely during membrane attachment to preserve elasticity. For rough or uneven concrete surfaces, priming with Tescon Primer RP or Tescon Sprimer can improve adhesion.

Thanks to their high adhesive strength and quick drying, timber battens do not need to be pressure-treated. When installing blown-in insulation, battens support the insulation and prevent strain on the sealant, ensuring the integrity of the airtight barrier over time.
