Osmo Exterior Gap Sealer is a high quality, one component, flexible sealant that has plasto-elastic qualities. It can be used for filling gaps in wood, fixing gaps between masonry, and sealing gaps in door and window frames.
This product can be used in conjunction with the Osmo Gap Sealer Gun Applicator.
Please Note: Osmo Exterior Gap Sealer is not suitable for joints exposed to continuous water immersion.
Ensure that surfaces to be sealed are clean, dry and free from dust, dirt, contamination and loose materials.
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.
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.
