{"product_id":"watco-liquid-waterproofer","title":"Watco Liquid Waterproofer","description":"\u003cp\u003eWatco Liquid Waterproofer is a cement and resin waterproofing coating for suitable concrete, brick and masonry. It forms a tough, flexible layer that resists water while remaining permeable to water vapour, making it useful for damp-prone basements, workshops and storerooms.\u003c\/p\u003e\n\u003cp\u003eThe Off White system is supplied as powder and liquid to be mixed before use. Its consistency can be adjusted using the supplied liquid for floors or suitable vertical applications, and the finished texture depends on the application method. The manufacturer also lists uses including balconies, walkways and certain tanks, subject to the full project specification. Correct preparation and total coating thickness are essential where water pressure is involved.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eCement and resin waterproofing system.\u003c\/li\u003e\n\u003cli\u003eSuitable for prepared interior and exterior masonry.\u003c\/li\u003e\n\u003cli\u003eFlexible coating for damp-proofing and resurfacing applications.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSurface Preparation\u003c\/h3\u003e\u003cp\u003eRemove grease, dust, laitance and other contamination.

The current product page recommends two coats. Increasing total thickness to meet a water-pressure specification increases material use: calculate from the required system thickness rather than the area alone.\u003c\/p\u003e\u003ch3\u003eDirections for Use\u003c\/h3\u003e\u003col\u003e\n\u003cli\u003ePlace the powder in a suitable bucket and add approximately three quarters of the supplied liquid. Mix with a slow-speed drill and paddle for about three minutes until smooth and lump-free.\u003c\/li\u003e\n\u003cli\u003eFor floors, add the remaining liquid and mix thoroughly. For other applications, use only enough of the supplied liquid to reach the specified consistency.\u003c\/li\u003e\n\u003cli\u003eApply to the damp, standing-water-free substrate with a suitable brush or roller. Keep each coat within the product page's 0.5–1.5mm application range.\u003c\/li\u003e\n\u003cli\u003eApply subsequent coats once the first has cured, normally after twelve to twenty-four hours. Allow approximately sixteen hours at 20°C for light traffic and seven days before permanent water pressure.\u003c\/li\u003e\n\u003c\/ol\u003e\u003ch3\u003eLimitations\u003c\/h3\u003e\u003cp\u003eThe required thickness depends on the application and water pressure. The linked technical sheet specifies 3mm total thickness for resistance to a 3m head of water; obtain a confirmed system specification for pressure-retaining work. Do not confuse initial drying with full water-pressure resistance. Remove food from the area during application and curing. Clean tools immediately with water, protect stored components from freezing and read both safety sheets.\u003c\/p\u003e\u003ch3\u003eProduct FAQs\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is supplied in the pack?\u003c\/strong\u003e\u003cbr\u003eA cement-based powder and liquid resin component, which are mixed together as directed before application.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eShould the concrete be dry before coating?\u003c\/strong\u003e\u003cbr\u003eNo. Prepare and saturate the surface, then apply while damp but free of standing water.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much area will one pack cover?\u003c\/strong\u003e\u003cbr\u003eApproximately 12.5m² at 1mm thickness for one coat.
