Clear Multi-Surface Waterproofer","description":"\u003cp\u003eThompson's WaterSeal Clear Multi-Surface Waterproofer is a water-repellent sealer for exterior wood, concrete and brick. It soaks into porous substrates and leaves a clear, non-film-forming barrier that sheds water rather than sitting on the surface as a coating, so the texture and color of the substrate are left essentially as found. The manufacturer lists it for use as a wood sealer, brick sealer and concrete waterproofer.\u003c\/p\u003e\n\u003cp\u003eSurfaces have to be clean and dry before application, and the splash test is the standard check on whether a surface needs treatment: sprinkle water on the substrate, and if it soaks in and darkens within a few seconds the surface is porous enough to seal. One light coat is enough in most applications, and the product goes on milky white and dries clear, which makes it easy to see what has already been covered. It can be brushed, rolled or put down with a pump-up garden sprayer.\u003c\/p\u003e\n\u003cp\u003eBecause it is a penetrating water repellent rather than a structural waterproofing membrane, it belongs on above-grade exterior work - it is not intended for below-grade use where hydrostatic pressure is a factor, and it is not a paint additive. Repeat the splash test annually to judge when the surface is due for a refresh.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eClear, transparent formula dries clear and helps maintain the natural color of the substrate\u003c\/li\u003e\n\u003cli\u003eProven to waterproof concrete, brick and exterior wood, so one product covers mixed-substrate exteriors\u003c\/li\u003e\n\u003cli\u003eOne coat is recommended; approximate coverage of 50 to 375 sq. ft. per gallon depending on the porosity of the surface\u003c\/li\u003e\n\u003cli\u003eApplies by brush, roller or pump-up sprayer; appears milky white while wet and dries clear\u003c\/li\u003e\n\u003cli\u003eSoap and water cleanup\u003c\/li\u003e\n\u003cli\u003eDry time of 24 to 72 hours; allow surface and air temperatures above 50F during application and for 48 hours after\u003c\/li\u003e\n\u003cli\u003ePenetrating water repellent rather than a film coating, so it does not peel the way a surface film can\u003c\/li\u003e\n\u003cli\u003eNot for below-grade applications where water pressure is a problem, and not to be used as a paint additive\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eExterior wood decks, stairs and railings\u003c\/li\u003e\n\u003cli\u003eFences, pergolas, arbors and outdoor furniture\u003c\/li\u003e\n\u003cli\u003eExterior wood siding and trim left natural\u003c\/li\u003e\n\u003cli\u003ePoured concrete patios, walkways and steps\u003c\/li\u003e\n\u003cli\u003eBrick and masonry walls, chimneys and veneer\u003c\/li\u003e\n\u003cli\u003eConcrete block retaining walls and garden walls\u003c\/li\u003e\n\u003cli\u003eSeasonal re-treatment of previously sealed exterior surfaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eProduct Details\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Thompson's WaterSeal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Line:\u003c\/strong\u003e Multi-Surface Waterproofers\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Clear multi-surface waterproofer \/ water-repellent sealer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOpacity:\u003c\/strong\u003e Clear\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFor Use In Location:\u003c\/strong\u003e Exterior\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSubstrates:\u003c\/strong\u003e Wood, concrete, brick and other exterior surfaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContainer Size:\u003c\/strong\u003e 1.2 gal.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApproximate Coverage:\u003c\/strong\u003e 50 - 375 sq. ft. per gallon\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable class=\"product-specs\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eVolume\u003c\/th\u003e\n\u003ctd\u003e1.2 GAL\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eBrand\u003c\/th\u003e\n\u003ctd\u003eThompson's WaterSeal\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Thompson's WaterSeal","offers":[{"title":"Default Title","offer_id":55048720089427,"sku":"32053241116","price":28.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1012\/7743\/4195\/files\/arch-placeholder-coming-soon_8cbe1853-4e54-4cf3-92f7-2d95adf707b9.webp?v=1790259776","url":"https:\/\/arch-9365.myshopify.com\/zh\/products\/thompson-s-waterseal-1-2-gal-clear-multi-surface-waterproofer-32053241116","provider":"ARCH","version":"1.0","type":"link"}
