Siroflex Instant Plaster Filler - White - 310ml

The Siroflex Instant Plaster Filler is primarily designed for interior use. It is not formulated for exterior conditions which may affect its durability and finish.

It can be overpainted in 10-20 minutes. Full curing time depends on application thickness, humidity, and temperature, but it's generally quick enough for most touch-up jobs within an hour.

For best results and to prevent shrinkage, it's recommended to apply the filler in thin layers for larger or deeper repairs, allowing each layer to set before applying the next.

It is suitable for use on most common interior wall and ceiling surfaces, including plaster, drywall, and previously painted areas.

While you can paint directly onto the filler after it's dry, priming is recommended for a more uniform finish, especially if the repaired area is large or if you are using a darker paint color.

Once opened, ensure the nozzle is sealed tightly (you can use tape or a suitable plug) and store the tube in a cool, dry place. It's best to use it within the recommended shelf life for optimal performance.

Yes, it's ideal for filling small gaps and cracks around window frames, door frames, and skirting boards.

Ensure the nozzle is cut correctly and the tube is properly seated in the caulking gun. Check if the filler has dried inside the nozzle and clear it if necessary.

While designed to be non-shrinking, excessively deep or wide gaps may require multiple thin applications rather than one thick layer. Ensure the surface is clean and free of dust before application.

Allow the filler to cure fully before attempting to sand. If it's still too soft, it may not have dried completely. For very hard sanding, ensure you are using appropriate sandpaper grit.

Ensure the filler is completely dry and cured before painting. A light sanding to create a key can improve paint adhesion. For best results, use a primer if painting over a large repaired area.
