{"product_id":"pts-r12","title":"PTS-R12","description":"\u003cp\u003e\u003cstrong\u003eA low-modulus, water-curable elastomeric membrane that seals interior and exterior surfaces with one product and no mixing.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003ePTS-R12 is a single-component, 100%-solids waterproofing membrane, adhesive, and coating from the PSI Poly-Tuff line. It cures by reaction with atmospheric moisture, so there is no two-part mixing, no measuring, and no pot-life waste. Roll, brush, trowel, or gun it to the thickness the job calls for and it builds a long-lasting, weather-tight seal that stays flexible through extreme temperature swings.\u003c\/p\u003e\n\u003cp\u003eThe chemistry bonds primerless to most common building substrates and grips even damp masonry, which keeps crews moving on real-world job sites. It is low odor and non-gassing, resists dirt pickup, and holds its elasticity from deep cold to summer heat. Use it as a stand-alone membrane, as a high-movement waterproofing layer, or as an elastic adhesive for flashing details and under Flexi-Ply systems.\u003c\/p\u003e\n\u003ch3\u003eSpecs\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e single-component, low-modulus, water-curable elastomeric waterproofing membrane, adhesive, and coating\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSolids:\u003c\/strong\u003e 100% by weight, 100% by volume\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White and Grey\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackaging:\u003c\/strong\u003e 2 gallon and 5 gallon pails\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoverage:\u003c\/strong\u003e apply not less than 30 mils for membrane and roof coating (about 50 sq ft per gallon); 60 mils for planter box and below-grade work (about 25 sq ft per gallon)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness:\u003c\/strong\u003e Shore A 30 ± 5 (low modulus)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eElongation at break:\u003c\/strong\u003e 300 to 400%\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eService temperature:\u003c\/strong\u003e -25°F to 200°F (-32°C to 93°C)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCure:\u003c\/strong\u003e skins in 15 to 45 min; water-cured cures through in 2 to 6 hr; cures in 1 to 2 days without added water\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApply above:\u003c\/strong\u003e 40°F (4°C)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards:\u003c\/strong\u003e meets ASTM C-836 and E-96; ASTM C-920 Type S, Grade NS, Class 25; primerless on most substrates; bonds to damp masonry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhere to use\u003c\/h3\u003e\n\u003cp\u003eInterior and exterior roofing, concealed waterproofing, under-tile and under-concrete waterproofing, planter boxes, parapet walls, expansion joints, green roofs, pot-hole filling, and leveling of uneven surfaces.

For heavy builds above 20 mils, or when weather is changing fast and you need a quicker set, blend in 4 to 5 ounces of water per gallon to water-cure it.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes it need a primer?\u003c\/strong\u003e\u003cbr\u003eIt is primerless on most substrates and bonds to damp masonry. Metal should be clean, rust-free, and solvent-wiped; new concrete and masonry should cure 14 days before application.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow thick should I apply it?\u003c\/strong\u003e\u003cbr\u003eNot less than 30 mils for membrane and roof coating applications, and 60 mils for planter box and below-grade waterproofing.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow fast does it cure?\u003c\/strong\u003e\u003cbr\u003eIt skins over in 15 to 45 minutes. Water-cured, it cures through in 2 to 6 hours depending on temperature, humidity, and thickness. Used without added water, cure runs 1 to 2 days.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I use it on vertical and overhead surfaces?\u003c\/strong\u003e\u003cbr\u003eYes. It is non-sag and can be applied vertical or overhead with a quality caulking gun. Apply when temperatures are above 40°F.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eDistributed and supported by Latux.\u003c\/em\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0814\/3178\/9786\/files\/PTS-R12-Data-Sheet.pdf?v=1786631485\" target=\"_blank\" rel=\"noopener\"\u003eDownload data sheet (PDF)\u003c\/a\u003e\u003c\/p\u003e","brand":"PSI","offers":[{"title":"White \/ 2 Gallon","offer_id":48337442996442,"sku":"PT-R12-WHITE-2","price":113.63,"currency_code":"USD","in_stock":false},{"title":"White \/ 5 Gallon","offer_id":48337443029210,"sku":"PT-R12-WHITE-5","price":284.11,"currency_code":"USD","in_stock":false},{"title":"Grey \/ 2 Gallon","offer_id":48337443061978,"sku":"PT-R12-GREY-2","price":113.63,"currency_code":"USD","in_stock":false},{"title":"Grey \/ 5 Gallon","offer_id":48337443094746,"sku":"PT-R12-GREY-5","price":284.11,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0814\/3178\/9786\/files\/9430841884890__5Gallon.png?v=1786908625","url":"https:\/\/latuxepoxy.com\/es\/products\/pts-r12","provider":"Latux Epoxy","version":"1.0","type":"link"}
