Side A (dark grey) and Side B (black) are premeasured and mixed on site to build a seamless, flexible base membrane over prepared concrete, plywood, or metal. With a short pot life and fast gel, it can be placed in a single pass or multiple coats and applied in temperatures as low as 20F, so crews keep moving when other basecoats stall.\u003c\/p\u003e\n\u003cp\u003eThe membrane can be fully reinforced with fabric while still wet, which speeds detailing at joints, drains, and flashings. It is relatively insensitive to moisture and temperature, making it a strong choice for pedestrian walkways, patios, stairways, sun decks, balconies, mechanical rooms, wash racks, kennel runs, and vehicular-traffic areas. Because pot life is short, mix only what the crew can place and reinforce immediately.\u003c\/p\u003e\n\u003ch3\u003eSpecs\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eChemistry:\u003c\/strong\u003e two-component, solvent-free hybrid polyurea urethane basecoat membrane\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Grey (Side A dark grey, Side B black)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMix:\u003c\/strong\u003e premeasured kits, Side A to Side B, do not dilute or estimate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSolids:\u003c\/strong\u003e 94% by weight, 95% by volume\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness:\u003c\/strong\u003e Shore A 80 ± 3 (ASTM D-2240)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTensile strength:\u003c\/strong\u003e 2,500 ± 100 pli (ASTM D-412)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eElongation:\u003c\/strong\u003e 800 ± 100% (ASTM D-412)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePot life:\u003c\/strong\u003e 10 ± 2 min at 75F \/ 50% RH\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTack-free:\u003c\/strong\u003e 3 to 4 hr\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow-temp application:\u003c\/strong\u003e down to 20F (-6.7C)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVOC:\u003c\/strong\u003e under 0.49 lb\/gal (59 g\/L)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoverage:\u003c\/strong\u003e 1,520 sq ft per gallon at 1 mil (theoretical; varies with build)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompliance:\u003c\/strong\u003e contains isocyanates\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackaging:\u003c\/strong\u003e 1-gallon kit (Side A 0.8 gal + Side B 0.2 gal); 5-gallon kit (Side A 4 gal + Side B 1 gal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShelf life:\u003c\/strong\u003e 12 months, factory-sealed, stored 60 to 95F\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eUse it with\u003c\/h3\u003e\n\u003cp\u003ePrime with the recommended Enviro-Grip PSI primer, detail joints and cracks with PTS E-101 sealant and reinforcement tape, and topcoat with a PSI wear coat.

The kit ratio is premeasured, so pair Side A and Side B in the same kit size (1-gallon or 5-gallon) to keep it correct.

B-Tuff 308 can be fully reinforced while wet, which makes flashing and detail work faster.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs it a finished surface?\u003c\/strong\u003e\u003cbr\u003eNo. It is a base membrane and must be topcoated.
