DESCRIPTION
WHY IT'S PERFECT FOR YOU

If you're sealing roofs, gutters, or flashings on multiple dwellings or across a larger project, buying MF50 by the box keeps your costs down and your site supplied.

The translucent formula cures flexible and UV stable, which means it doesn't crack or discolour on exposed rooflines. AS4020 potable water approval makes it suitable for rainwater collection systems and gutters that feed tanks — not just standard drainage.

Low odour neutral cure is safer to use in enclosed or partially enclosed spaces compared to acetic-cure silicones. Apply with a standard caulking gun to concrete, masonry, metal, or stone.
