It is the value-focused base membrane in the range: one component, easy to premix and squeegee out, and proven over prepared concrete, masonry, plywood, wood, and metal. A low-VOC SC grade is available where 100 g\/L limits apply.\u003c\/p\u003e\n\u003cp\u003eApply a continuous, even coat across the deck at roughly 50 to 60 sq ft per gallon, detail joints and cracks with reinforcement tape and sealant, and let it moisture-cure before topcoating. Add B-Tuff 302 Accelerator when the schedule calls for a faster turn. As with all PSI base membranes, it is covered by a wear-rated topcoat rather than left exposed.\u003c\/p\u003e\n\u003ch3\u003eSpecs\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eChemistry:\u003c\/strong\u003e single-component, moisture-cured aromatic-urethane basecoat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Grey or Tan\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSolids:\u003c\/strong\u003e 81% by weight, 71% by volume (standard grade)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness:\u003c\/strong\u003e Shore A 55 ± 5 (ASTM D-2240)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTensile strength:\u003c\/strong\u003e 800 ± 100 psi (ASTM D-412)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eElongation:\u003c\/strong\u003e 500 ± 50% (ASTM D-412)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVOC:\u003c\/strong\u003e 2.01 lb\/gal (240 g\/L) standard; low-VOC SC grade at 0.78 lb\/gal (94 g\/L)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoverage:\u003c\/strong\u003e 50 to 60 sq ft per gallon per coat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCure:\u003c\/strong\u003e 12 to 16 hr, or 6 to 8 hr with accelerator (75F \/ 50% RH)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSubstrates:\u003c\/strong\u003e concrete, masonry, plywood, wood, metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackaging:\u003c\/strong\u003e 1 gallon, 5 gallon; 55-gallon drum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShelf life:\u003c\/strong\u003e 6 months, factory-sealed, stored 60 to 95F; contains isocyanates and solvents\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eUse it with\u003c\/h3\u003e\n\u003cp\u003ePrime with an Enviro-Grip PSI primer (EP#1, EP#2, or PUR#555 for recoats), bridge joints and cracks with PTS E-101 and reinforcement tape, and finish with a PSI topcoat.
