Ready to use with only the addition of potable water, it mixes to a stiff, no-slump putty consistency in under 30 seconds and achieves flash set in 1 to 3 minutes. A slower 3 to 5 minute set formulation is also available for applications where more working time is needed. Licensed masons, waterproofing contractors, and concrete repair specialists install this product in active-leak conditions where standard patching materials cannot perform.\u003c\/p\u003e\u003cp\u003eThis hydraulic cement is suited for residential, commercial, and civil infrastructure repair scenarios where water is actively infiltrating through cracks, joints, or voids in concrete or masonry. Typical applications include below-grade foundation walls, tunnels, utility vaults, elevator pits, and wet basements. The material is designed for saturated surface dry (SSD) conditions and can be applied directly into running-water situations. Compatible surfaces include structurally sound concrete and masonry that have been mechanically abraded to a surface profile of CSP greater than 3 per ICRI Guideline 310.2.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRapid flash set in 1 to 3 minutes stops active water flow on contact\u003c\/li\u003e\n\u003cli\u003eSlower 3 to 5 minute set option available for extended working time\u003c\/li\u003e\n\u003cli\u003eMixes to a hand-formable, stiff putty consistency with no slump\u003c\/li\u003e\n\u003cli\u003eRequires only potable water — approximately 1 quart per 8 to 9 pounds of material\u003c\/li\u003e\n\u003cli\u003eSuitable for SSD and actively running-water conditions\u003c\/li\u003e\n\u003cli\u003eDesigned for use on structurally sound concrete and masonry substrates\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a hydraulic water-stop repair compound for use on concrete and masonry substrates meeting ICRI Guideline 310.2 surface preparation requirements. Exposed steel surfaces in the repair area should be primed with DURALPREP A.C. prior to application.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed waterproofing contractor or qualified mason familiar with hydraulic cement products. Before mixing, ensure the substrate is structurally sound and mechanically abraded to the required surface profile. Mix rapidly with a trowel for no more than 30 seconds and form immediately into the void — set begins within minutes and cannot be reversed once initiated. Do not re-temper or rework the mix after set begins.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSet Time (Standard Formula)\u003c\/strong\u003e: 1 to 3 minutes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSet Time (Slow Formula)\u003c\/strong\u003e: 3 to 5 minutes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMix Ratio\u003c\/strong\u003e: approximately 1 quart water per 8 to 9 pounds of material\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMix Time\u003c\/strong\u003e: no more than 30 seconds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSurface Profile Requirement\u003c\/strong\u003e: CSP greater than 3 per ICRI Guideline 310.2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContainer Size\u003c\/strong\u003e: 5 gallon\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: METRO SEALANT WATERPROOFING SUPPLY\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 561857\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"METRO SEALANT \u0026 WATERPROOFING SUPPLY","offers":[{"title":"Default Title","offer_id":51620383555890,"sku":"561857","price":110.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2A73139C-5C77-444A-8B53-E14B1BCC4350-scaled-1-768x768_jpeg.webp?v=1787342543","url":"https:\/\/voomisupply.com\/products\/metro-sealant-561857-hydraulic-cement-water-stop-5-gallon","provider":"Voomi Supply","version":"1.0","type":"link"}
