Junckers Prefill is a single-pack, fast drying water-borne pre-filler which fills up gaps, cracks and knots easily on internal timber floors when mixed with sanding dust. For use with Junckers other water-based floor systems only (Junckers Strong, High Performance Sport & Commercial).
Coverage is difficult to estimate because it is dependent on the condition of the floor, but allow a maximum coverage of 20 square meters per litre. Drying times: Approximately 45-90 minutes (at 20°C and normal drying conditions). Apply using a broad bladed filling/smoothing knife etc. When using Junckers Prefill, mix enough sanding dust into Junckers Prefill until a thick but spreadable paste is obtained. If too thick dilute with water.
