Formerly marketed as Super ThoroSeal White, this product delivers a long-lasting, semi-smooth decorative white finish while creating a durable moisture barrier. Sold as a single 5-gallon unit weighing 38 pounds, it is applied by masonry contractors, waterproofing specialists, and experienced trade professionals working on below-grade or above-grade concrete and block assemblies.\u003c\/p\u003e\u003cp\u003eMS583WH5G is suited for residential and commercial masonry waterproofing applications where a surface coating must resist hydrostatic pressure, dampness, and general moisture migration. Typical installation scenarios include foundation walls, retaining walls, concrete block, poured concrete, stucco, and similar masonry substrates requiring a protective, water-resistant finish coat. Its white finish also serves light decorative purposes in addition to its primary protective function.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePolymer-modified portland cement formulation for strong adhesion to concrete and masonry\u003c\/li\u003e\n\u003cli\u003eResists water intrusion, dampness, and seepage at the substrate surface\u003c\/li\u003e\n\u003cli\u003eSemi-smooth white finish provides a clean, finished appearance after application\u003c\/li\u003e\n\u003cli\u003eFormerly known as Super ThoroSeal White — direct successor product for existing users\u003c\/li\u003e\n\u003cli\u003e5-gallon unit size suitable for mid-to-large coverage areas\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement coating for concrete and masonry waterproofing applications where polymer-modified cement-based surface treatments are specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eApplication is typically performed by masonry contractors or waterproofing professionals familiar with surface preparation requirements for cementitious coatings. The substrate must be clean, sound, and free of oil, efflorescence, loose material, and standing water prior to application. Follow manufacturer mixing instructions carefully, as improper water-to-powder ratios will affect adhesion and water resistance. Refer to local building codes and project specifications for required coating thickness and curing conditions.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 38 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContainer Size\u003c\/strong\u003e: 5 gallons\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Semi-smooth white\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBase Material\u003c\/strong\u003e: Polymer-modified portland cement\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00080492050103\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HONEYWELL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MS583WH5G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HONEYWELL","offers":[{"title":"Default Title","offer_id":51342875853106,"sku":"MS583WH5G","price":78.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310549538.jpg?v=1782009275","url":"https:\/\/voomisupply.com\/products\/honeywell-ms583wh5g-masterseal-583-masonry-waterproofer","provider":"Voomi Supply","version":"1.0","type":"link"}
