•     Accurate and economical dosage
•     Quick and simple to use, genuinely saves time
•     Suitable for bonding on vertical surfaces
•     Dries quickly without shrinkage
•     Low expansion for rapid, reliable positioning of panels and parts to be bonded
•     Good mechanical strength and thermal and acoustic insulation
•     Flexible, does not crumble
•     Solvent-free for working in comfort
•     Resistant to solvents, paints and other chemicals
•     Not sensitive to ageing
•     Rot-proof. Good mould resistance
•     Not UV-resistant

Hazardous. Follow the precautions for use

Application area

Multi-purpose adhesive for durable, economical and effective fixing of exterior and interior thermal insulation panels. Also suitable for fixing dry walling, aerated concrete, internal non-load bearing walls, partition walls, etc. Sticks to all standard construction surfaces such as concrete, plaster, brick, stone, timber, cork, steel, galvanised steel, rigid PVC, bituminous surfaces, extruded and expanded polystyrene, fibreglass, etc. Can also be used for assembly of electrical junction boxes

Instructions

Shake aerosol vigorously before use (for around 30 seconds). Screw the gun to the aerosol valve. First, protect any surfaces around the working area. Degrease and clean the surfaces to be treated. Regularly shake the aerosol during application. Any adhesive that has not hardened may be removed with a suitable product or some acetone. Hardened adhesive can only be removed mechanically

Insulation panels

For best results, keep the gun at a distance of around 1–2 cm from the surface to be bonded. Apply the adhesive in 30 mm thick lines, in vertical strips, on the contours and in a W shape, keeping at least 3 cm from the edge. Check that at least 40% of the surface is covered with adhesive when pressing the panel on to the surface. Lightweight panels can be applied immediately without waiting. With heavier materials, depending on weather conditions, wait 4 to 8 minutes before applying. Then place the panel or part to be bonded on the surface, pressing heavily for 30 seconds to 1 minute. Check the position and adjust if necessary with an appropriate tool. In some cases, temporary additional mechanical fastening may be necessary

Non-load bearing walls

Bonding of bricks, aerated concrete, stone, granulated slag brick, only for making non-load bearing walls. Apply the adhesive horizontally in 30 mm lines. No waiting time necessary.
