{"product_id":"usg-4-5-gal-ready-mixed-joint-compound-jc5gl","title":"USG 4.5 Gal. Ready-Mixed Joint Compound","description":"\u003cp\u003eUSG ready-mixed drywall joint compound, supplied wet in a resealable plastic pail. The material comes premixed to a spreadable consistency, so it can be pulled straight from the bucket onto a hawk or pan and worked with a taping knife without batching powder and water on site.\u003c\/p\u003e\n\u003cp\u003eReady-mixed compounds are air-drying rather than chemically setting: they stiffen as water leaves the film, which keeps working time open and allows a coat to be reworked while it is still wet. Because each coat shrinks a little as it dries, joints are built up in successive passes - a bedding coat that embeds the tape, then fill and finish coats - with full drying and light sanding or sponging between passes.\u003c\/p\u003e\n\u003cp\u003eThe compound is an interior finishing material and must be kept above freezing in storage; repeated freeze-thaw cycling breaks the emulsion and ruins the mix. Finished joints and skim coats should be primed before paint so the compound and the surrounding paper face take colour evenly.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePremixed and ready to use from the pail, with no powder-and-water batching required on site\u003c\/li\u003e\n\u003cli\u003eAir-drying formulation that hardens as water evaporates, leaving an open working time for tooling and reworking\u003c\/li\u003e\n\u003cli\u003eConsistency can be adjusted with small additions of clean water for hand knives or mechanical finishing tools\u003c\/li\u003e\n\u003cli\u003eDries to a surface that sands and sponges easily for a smooth, level joint\u003c\/li\u003e\n\u003cli\u003eBuilds in multiple coats over tape, fasteners and bead to compensate for drying shrinkage\u003c\/li\u003e\n\u003cli\u003eSupplied in a resealable pail so unused material can be closed up and kept workable between coats\u003c\/li\u003e\n\u003cli\u003eInterior use only; protect from freezing in storage and transit\u003c\/li\u003e\n\u003cli\u003eAccepts primer and finish paint once the compound is thoroughly dry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eEmbedding paper joint tape at tapered and butt joints in gypsum board\u003c\/li\u003e\n\u003cli\u003eFill and finish coats over taped joints, fastener heads and metal corner bead\u003c\/li\u003e\n\u003cli\u003eSkim coating wall and ceiling surfaces to level texture variation before priming\u003c\/li\u003e\n\u003cli\u003ePatching cracks, dings and fastener pops in existing drywall and plaster surfaces\u003c\/li\u003e\n\u003cli\u003eFinishing interior partitions, soffits and ceilings in residential and commercial fit-out\u003c\/li\u003e\n\u003cli\u003eRepair work around outlet cut-ins, trim removal and small openings\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 USG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Drywall Joint Compound\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eForm:\u003c\/strong\u003e Ready-Mixed (wet, premixed)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardening Method:\u003c\/strong\u003e Air-drying\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContainer:\u003c\/strong\u003e Resealable pail\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUse Location:\u003c\/strong\u003e Interior\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\"\u003eWeight\u003c\/th\u003e\n\u003ctd\u003e61.7 LB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eVolume\u003c\/th\u003e\n\u003ctd\u003e4.5 GAL\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eBrand\u003c\/th\u003e\n\u003ctd\u003eUSG\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"USG","offers":[{"title":"Default Title","offer_id":55112700264787,"sku":"JC5GL","price":19.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1012\/7743\/4195\/files\/usg-4-5-gal-ready-mixed-joint-compound-jc5gl.webp?v=1790734561","url":"https:\/\/arch-9365.myshopify.com\/zh\/products\/usg-4-5-gal-ready-mixed-joint-compound-jc5gl","provider":"ARCH","version":"1.0","type":"link"}
