The Bonda Glass Fibre Reinforced Filler is one of the most useful 'tins of power' you can have.

It is a rapid hardening resilient filler with high glass fibre content. Very good and useful for sealing round pipes and bottom drains etc in a concrete constructed pond and ideal for repairing fractures, splits and holes in glass fibre ponds and tanks.

Hardens off within 1 hour.
