Description
Parfix Foam Fill Triple Expanding Filler is a polyurethane foam in a 750g aerosol can, made for packing out large gaps, cracks and cavities in and around the home. It expands well beyond its sprayed volume to fill irregular voids, then cures to a durable, water resistant foam that bonds to most common building surfaces.
About the formula
A one-part polyurethane foam based on an isocyanate (MDI) prepolymer, supplied in a pressurised can. Once cured it is a firm, shrink resistant foam that can be cut, sanded and painted. Cured foam is not UV resistant, so exposed outdoor areas should be painted or covered.
Where to use it
Indoors: gaps around pipes and cable penetrations, cracks and holes in walls, and cavities around frames and fittings.
Outdoors: holes and gaps in brickwork and other building surfaces, protected from direct sunlight once cured.
Suitable for most building surfaces, including timber, metal, brick, stone and other masonry. Test on a small hidden area first if you are unsure about a particular material.
How to use it
Wear gloves and safety glasses and work in a well ventilated area. Make sure surfaces are clean and free of loose material, dust and grease. Follow the directions printed on the can for shaking, nozzle attachment and application. Because this foam expands strongly, fill the gap only partly and allow room for growth rather than over-filling. Once fully cured, trim any excess with a knife or saw, then sand or paint as required. Uncured foam is best wiped off straight away with a suitable cleaner as directed on the can. Cured foam must be cut or sanded off.
Important notes
Not UV resistant, so paint or coat any foam that will be exposed to sunlight. Take care not to over-fill, as expanding foam can distort thin frames, door jambs and window casings. Keep the can away from heat, flames and sources of ignition. Check the can label for temperature range, cure times and further directions, as these are not covered in the product data we hold.
