Epoxy Filler · Lapox · 1.8 kg

Lapox Fillo — stays where you put it, even on verticals.

Lapox Fillo is a two-component thixotropic epoxy adhesive — thick enough to stay on walls and overhead surfaces, strong enough to bond glass, metals, wood, and stone. Si Epoxy has stocked it since 2019 and it remains the product recommended most often for vertical gap filling and joint repairs. It filled wall joints in a pharmaceutical warehouse in Baddi with zero drip risk and potted transformer units in an electronics workshop in Ghaziabad. As of August 2026, a 1.8 kg bottle is ₹835 incl GST from our Ghaziabad warehouse.

Which Project Should You Use Lapox Fillo For?

Fillo is for gaps, joints, and vertical repairs. If the job needs a thick material that holds its shape, it is the right tool. If you need a bond in seconds or a structural stone setting, the other Lapox products take over.
