Fosroc Nitocote VF — Epoxy Putty for Void Filling and Surface Defect Repair in Concrete ( 1 box - 12pcs)

Concrete surfaces rarely come off the formwork in perfect condition. Honeycombed areas, blow holes, surface voids, tie rod holes, form joint offsets and minor surface defects are common on cast concrete — and they create two problems. Structurally, surface voids allow moisture and aggressive chemicals to penetrate directly to the reinforcement level. Practically, they prevent protective coatings, waterproofing membranes and decorative finishes from achieving continuous bond across the surface — causing coating failure that initiates at every unfilled void.

Fosroc Nitocote VF is an epoxy putty engineered for void filling and surface defect repair in concrete prior to the application of protective coatings, waterproofing systems and surface treatments. The knife-grade consistency allows it to be pressed firmly into blow holes, honeycombed areas, tie rod holes and surface voids — filling them completely and flush with the surrounding concrete surface — before being tooled smooth to provide a continuous, defect-free substrate for subsequent coating application.

The epoxy formulation bonds strongly to prepared concrete substrates, cures to a hard, dense fill that does not shrink away from the void edges, and provides a chemically resistant filled surface that stands up to the same aggressive conditions as the coating system applied over it. The result is a substrate that gives protective coatings and waterproofing membranes the continuous, defect-free bond surface they need to perform to their full design life — without voids acting as stress concentration points or moisture entry paths beneath the coating.

For protective coating applicators, waterproofing contractors and civil engineers working on concrete substrate preparation for coating, lining or waterproofing systems — Fosroc Nitocote VF delivers the epoxy putty performance that void-free concrete substrate preparation demands.

A construction chemical surface preparation solution from Fosroc for concrete finishing before coating — Nitocote VF is the epoxy putty specification for void filling and defect repair where a continuous, defect-free substrate is the requirement.
