Overview
Osmo Gap Sealer is a high quality, one component, flexible gap filler that has plasto-elastic qualities. It can be used for filling, fixing and repairing all manner of splits and gaps, as well as sealing and filling joints on both finished and unfinished wood flooring, skirting board and door thresholds.
Coverage is dependent on gap width and depth, but as a guide, based on 3mm gaps, a 310ml tube will fill around 30 linear metres.

- Cut the dome seal of the tube with a sharp knife, taking care not to damage the thread

- Cut nozzle top at angle to suite size and shape of gap to be filled
- Porous surfaces such as concrete, stone, cement and plaster can be primed with a mixture of one part acrylic sealant and 4-5 parts water
Application
Always do a test area before starting any project to assess product suitability and final finish. Follow the manufacturer's instructions on the tube at all times. For the best results, application temperature should be between: 5°C and 40°C.
- Apply Osmo Gap Sealer to gaps between joinery and other substrates of between 5mm/25mm (recommended joint depth/width ratio is 1 to 2)
- Immediately after the application, smooth the sealant at once with wet finger or a wet tool
- Excess gap sealant can be removed with a damp, lint-free cloth
- Keep the sealed joint dry for at least two hours
- Cured sealant can be removed mechanically
