{"product_id":"watco-bund-sealer","title":"Watco Bund Sealer","description":"\u003cp\u003eWatco Bund Sealer is a glass-flake reinforced epoxy coating for sealing suitable containment areas, concrete and small areas of metal. Its high-solids, two part formulation creates a thick, glossy protective film with resistance to a wide range of chemicals, making it useful around tanks, pipes and bund walls and floors.\u003c\/p\u003e\n\u003cp\u003eA continuous coating is essential in a containment area. Bund Sealer is normally applied in one full coat, with additional material where a rough or porous surface needs it. Minor cracks and floor-to-wall junctions can be reinforced using the specified fibreglass tape detail. Choose Black or Light Grey, and check the technical sheet's chemical-resistance information against the substances, concentrations and exposure conditions involved.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eGlass-flake reinforced epoxy for chemical-resistant protection.\u003c\/li\u003e\n\u003cli\u003eFor suitable interior and exterior containment surfaces.\u003c\/li\u003e\n\u003cli\u003eOne full coat normally provides the specified film.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSurface Preparation\u003c\/h3\u003e\u003cp\u003eThe surface must be sound, clean and free of dust, oil and loose material. Remove contamination with a cleaner suited to the substrate and rinse as directed. Abrade sound retained paint and remove weak or defective coatings. New concrete normally needs eight weeks to dry. Repair larger cracks before coating; use the specified fibreglass tape detail at suitable minor cracks and junctions.\u003c\/p\u003e\u003ch3\u003eTechnical Data\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003ePack size \/ colours\u003c\/th\u003e\n\u003ctd\u003e4L \/ Black and Light Grey\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eComposition\u003c\/th\u003e\n\u003ctd\u003eTwo part, glass-reinforced epoxy\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCoverage film thickness\u003c\/th\u003e\n\u003ctd\u003e300 microns\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMinimum conditions\u003c\/th\u003e\n\u003ctd\u003eAir 10°C; substrate 5°C; best results from 15°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePot life\u003c\/th\u003e\n\u003ctd\u003e25 minutes at 20°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eShelf life\u003c\/th\u003e\n\u003ctd\u003e24 months unopened\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003ch3\u003eCoverage\u003c\/h3\u003e\u003cp\u003eApproximately 14m² per 4L (3.5m²\/L). Do not exceed this spread rate. Rough, porous or open-textured surfaces may need another coat to create a complete, continuous film.\u003c\/p\u003e\u003ch3\u003eDirections for Use\u003c\/h3\u003e\u003col\u003e\n\u003cli\u003eStir each component separately, combine the full pack and mix thoroughly with a wide bladed tool, scraping the sides and base. Do not thin or part mix.\u003c\/li\u003e\n\u003cli\u003eTransfer the mixed coating promptly into a suitable tray or bucket and use immediately; epoxy left in the mixing tin generates heat.\u003c\/li\u003e\n\u003cli\u003eApply a full coat with a brush or roller, working it into the substrate. Reinforce specified details and inspect for incomplete coverage.\u003c\/li\u003e\n\u003cli\u003eAt 20°C, the technical sheet gives twelve hours for light traffic, twenty-four hours for heavy traffic and seven days for full chemical resistance. Do not wash or leave water standing on the surface for at least seven days.\u003c\/li\u003e\n\u003c\/ol\u003e\u003ch3\u003eLimitations\u003c\/h3\u003e\u003cp\u003eDo not apply to wet surfaces or areas subject to rising damp. The technical sheet excludes locations with structural movement or vibration. Check the complete chemical-resistance schedule rather than assuming resistance to every chemical. Light Grey can discolour under UV without necessarily losing durability. Condition material at 15–25°C before use and protect from freezing.\u003c\/p\u003e\u003ch3\u003eProduct FAQs\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWill one coat be enough?\u003c\/strong\u003e\u003cbr\u003eUsually, at the specified 14m² per 4L rate.
