Natural Mineral Filler

A lime-based filler, made a kinder way. Natural Mineral Filler is bound with natural hydraulic lime instead of gypsum or cement, a breathable mineral binder that has smoothed walls for centuries. A fine filler for levelling and preparing interior walls before you decorate.

Unlike ordinary lime fillers, it bonds to low-absorption surfaces, so it fills straight over sound painted walls as well as bare plaster, plasterboard and cement renders, with no stripping back needed. Make sure existing paint is sound, remove any flaking first and test a small area.

  • Cement-free, solvent-free and negligible in VOC
  • Breathable and vapour-permeable, so your walls can breathe
  • Low shrinkage, high elasticity
  • Internal use, apply in coats up to 10 mm, conforms to BS EN 998-1

Mixing: add roughly 0.2 to 0.24 litres of clean water per kg to a smooth paste (whisk 4 to 5 minutes). Use within 4 hours.

Available in 1 kg, 3 kg, 5 kg and 10 kg.

Contains natural hydraulic lime. Danger: causes skin irritation and serious eye damage. Wear protective gloves and eye protection, and keep out of reach of children. Safety Data Sheet available on request.
