Polyurethane Filla Foam Crack Filler

Benefits

• Quick expanding rate - high foaming speed.
• Quick expanding rate - high foaming speed.
• Weatherproof - excellent water resistance.
• Insulating - excellent thermal and acoustic insulation.
• Versatile-cured products can be cut, plastered, drilled and painted.
• Good dimensional stability - won't crack with movement.
• Good sag resistance - does not run off vertical surfaces.
• No priming required - excellent primerless adhesion to most construction materials.
• Gap filling - moulds itself to surface irregularities.
• Will not rot - does not support mould or fungus.
• Chemical resistant - not affected by most solvents.

Applications

• Fills cracks, joints and gaps around pipes, vents, utility lines and electrical outlets.
• Seals out drafts around windows, doors and baseboards.
• Fills large gaps and spaces between prefab elements.
• Provides structural space e.g. below shower tray.
• Seams between chimneys, roof panels and wall panels.
• Insulates vehicles, caravans and boats.
• Insulating electrical outlets.
• Thermal, sound and water insulation.
• Bonds roof tiles.
• Gluing of insulating panels like polyurethane and polystyrene.
• Increases the rigidity of structures.
• Backing material before the application of sealants.
• Rodent and insect barrier.

Limitations

• Must be coated if exposed to sunlight/UV.
• Not to be applied below 5ºC.
• Does not bond to polyethene, polypropylene, Teflon or silicone.

Cleaning

• Any excess uncured foam can be removed with an organic solvent e.g. thinners or acetone (nail varnish remover).
• Cured foam can only be removed mechanically, and may leave a stain on surfaces.
• Hold the can upright and briefly press the trigger to use the propellant to remove any foam blocking the valve
• adaptor. Take care not to eject all the propellant during the cleaning process.
• Clean the nozzle and valve with thinners or acetone immediately after use.
