Dunlop Flexible Acrylic Filler is a high performance, one part, gunnable acrylic filler that remains flexible after drying. Designed for both interior and exterior use, it’s ideal for filling gaps around skirting boards, coving, window and door frames, as well as repairing cracks and damage to walls and ceilings. Its highly flexible nature prevents cracking or de-bonding on drying and it’s compatible with most water-based and synthetic paints.

Dunlop Flexible Acrylic Filler is perfect for

• Filling gaps around door and window frames (timber or UPVC)
• Sealing along skirting boards and coving
• Filling gaps between walls and ceilings
• Sealing around internal fittings
• Repairing cracks in walls and ceilings
• Any areas subject to movement where a flexible finish is required

No, like most flexible fillers, Dunlop Flexible Acrylic Filler cannot be sanded. For the best finish, smooth it while still wet using a damp finger or tool.

Although Dunlop Flexible Acrylic Filler is water resistant and can be used externally, it is not completely waterproof. For areas that are constantly exposed to water, a silicone sealant such as Dunlop FX-90 Silicone Sealant would be more appropriate.

Dunlop Flexible Acrylic Filler offers superior flexibility and anti-cracking properties compared to standard decorator caulks. It’s specifically designed to accommodate movement in the building, which means it won’t crack or split over time. Its unique formulation means it’s less likely to cause problems when painted over, a common problem with other caulks that can lead to unsightly cracks in the paint finish.

A 310ml cartridge of Dunlop Flexible Acrylic Filler will cover approximately 8.5 metres with a 6mm x 6mm bead.

Yes, that’s exactly what it’s designed for! Dunlop Flexible Acrylic Filler is ideal for areas subject to movement and thermal expansion, like the junction between different building materials or around fixtures. Its flexibility allows it to move with the building without cracking.

Remember, for best results with any decorating project, proper preparation is key. Ensure surfaces are clean and stable before applying Dunlop Flexible Acrylic Filler for a professional finish that lasts.
