Toupret Fill-Flex Flexible Filler White 310ml — Cracks in Flexible Surfaces

Ready-to-use, highly flexible filler designed for filling and sealing gaps and cracks in both interior and exterior applications. It is formulated for areas where movement can occur after application, such as skirting boards, staircases, architraves, window frames, and door frames. The flexible formulation is designed to accommodate minor substrate movement, helping to reduce the risk of cracking in normal service conditions.

This flexible gap and crack filler is suitable for use on a wide range of common construction and decorating surfaces, including gypsum plaster, plasterboard, cement, concrete, cellular concrete, breeze blocks, bricks, stone, masonry, primed wood, and previously painted surfaces. It can be used on both new and renovation projects, on surfaces that are painted or unpainted.

The product is supplied ready to use in a cartridge with a nozzle for controlled application into joints, gaps, and linear cracks. This format allows precise application, particularly in trim work and detailed areas around woodwork and masonry. It is designed to adhere to many typical building substrates, including plaster, masonry, primed timber, and existing paint layers. Whether spot priming is required depends on the specific surface condition and preparation, so a sound, clean, and suitable substrate is always important for best results.

Once applied and fully cured, the filler can be overcoated with standard decorative paints used in interior and exterior decorating. Drying and curing times can vary depending on joint size, temperature, humidity, and ventilation conditions, so sufficient curing time should always be allowed before overpainting.

This product is intended for general building maintenance, repair, and finishing work where a durable, flexible seal is required to accommodate minor movement and help maintain a neat finish over time.
