The adhesive produces a tough, flexible film that accommodates thermal movement and maintains adhesion across seasonal temperature change.\u003cbr\u003e\u003cbr\u003eIt provides strong bonding performance on concrete, asphalt, metal, wood and existing felt, creating a consistent seal for lap joints and full-coverage bonding layers. Its resistance to dilute acids, alkalis, salt solutions, water and alcohol supports reliable performance in exposed roofing conditions, enhancing the durability of built-up felt systems.\u003cbr\u003e\u003cbr\u003eThe adhesive is also suitable for use as a cold-gritting solution, enabling the application of chippings to the final felt layer for UV protection and surface durability. Designed for brush or mop application, it develops full tack within 15-30 minutes depending on ambient drying conditions, ensuring predictable laying characteristics on site.\u003cbr\u003e\u003cbr\u003eStored correctly and applied in accordance with BS 8217 felt-laying principles, the adhesive supports long-term weathering performance and provides consistent results across multiple roof types. \u003cbr\u003e\u003cbr\u003eThe 5 litre capacity offers practical coverage for medium-sized roofing works and continuous-run bonding.\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\u003ch2\u003eFeatures \u0026amp;
